1. The Perioperative Patient Focused Model presents key components of nursing influence that guide patient care. Select the statement that best describes the dynamic relationship within the model.

a.The patient experience and the nursing presence are in continuous interaction.b.Structure, process, and outcome are the foundation domains of the model.c.The perioperative nurse is the central dynamic core of the model.d.The interrelated nursing process rings bind the patient to the model.

ANS:  A

The Perioperative Patient Focused Model consists of domains or areas of nursing concern: nursing diagnoses, nursing interventions, and patient outcomes. These domains are in continuous interaction with the health system that encircles the focus of perioperative nursing practice—the patient.

REF:   Pages 2-3

1. AORN’s Standards of Perioperative Nursing Practice that describe nursing interactions, interventions, and activities with patients fall under which standards category?

a.Evidence-basedb.Processc.Outcomed.Structural

ANS:  B

Process standards relate to nursing activities, interventions, and interactions. They are used to explicate clinical, professional, and quality objectives in perioperative nursing.

REF:   Page 4

1. Which order best describes the process used to implement evidence-based professional nursing?

a.Literature search, theory review, data analysis, policy developmentb.Regional survey, literature search, meta-analysis, practice changec.Identify problem, scientific evidence, develop policy, evaluate outcomed.Identify issue, analyze scientific evidence, implement change, evaluate process

ANS:  D

Evidence-based practice is a systematic, thorough process by which to identify an issue, to collect and evaluate the best evidence to design and implement a practice change, and to evaluate the process.

REF:   Page 12

1. The ambulatory surgery unit is planning to develop a standardized skin preparation practice for their unit. The best process to gather scientific information is to:

a.conduct a survey of skin prep policies at the next AORN chapter meeting.b.review their surgical site infection data from the last 6 months.c.conduct a literature search on antimicrobial agents and infection prevention.d.review the scientific literature from the leading manufacturers of prep solutions.

Perioperative nurses have an ethical responsibility to review practices and to modify them, based upon the best available scientific evidence, using research and other forms of high-quality evidence to guide practice.

REF:   Page 12

1. The cardiac team is developing a standardized sterile back table setup and is unable to find sufficient research evidence for their project. Where might they look for information on best practices?

a.Survey regional facilities that perform cardiac surgery for their back table models.b.Review case studies and expert opinions on sterile back table setups.c.Review AORN’s recommended practice on creating the sterile field.d.All of the options are correct.

ANS:  D

When there is not enough evidence to guide practice, perioperative nurses should consider gathering information from varied trusted sources that reflect best practices.

REF:   Pages 13-14

1. How do institutional standards of care, such as policies and procedures, differ from national standards, such as AORN’s Standards of Perioperative Nursing Practice?

a.They are written by nurses.b.They are written specifically to address responsibilities and circumstances.c.They are collaborative and collective agreement statements.d.They are rarely based on research.

ANS:  B

Institutional standards apply to the system or facility that develops them and can be directive about specific actions in specific circumstances; national standards provide generalized authoritative statements that can be implemented in all settings.

REF:   Pages 3, 12

1. Which of the following actions best describes an element of the perioperative nursing assessment?

a.Scanning the surgical schedule for the day before morning reportb.Reading the pick/preference list attached to the case cartc.Reviewing the patient medical recordd.Studying an on-line tutorial about the intended surgical procedure

ANS:  C

Assessment is the collection of relevant health data about the patient. Sources of data may be a preoperative interview with the patient and the patient’s family; review of the planned surgical or invasive procedure; review of the patient’s medical record; examination of the results of diagnostic tests; and consultation with the surgeon and anesthesia provider, unit nurses, or other personnel.

REF:   Page 5

1. Lonna Weber is a frail 76-year-old diabetic woman who is scheduled for major surgery. She is vulnerable and at high risk for harm because of several factors related to her preexisting conditions and overall health status. As part of developing a plan to guide Lonna’s care, the nurse uses standardized descriptive terms to guide care. This step of the nursing process is called:

a.nursing diagnosis.b.nursing assessment.c.nursing outcome.d.nursing intervention.

ANS:  A

Nursing diagnosis is the process of identifying and classifying data collected in the assessment in a way that provides a focus to plan nursing care.

REF:   Page 7

1. During the admission interview, the nurse initiated the discharge teaching and demonstrated crutch-walking activities. The teaching activities are what stage of the nursing process?

a.Nursing assessmentb.Nursing implementationc.Nursing outcome preparationd.Nursing evaluation

ANS:  B

Implementation is performing the nursing care activities and interventions that were planned and responding with critical thinking and orderly action. Implementation is the “work” of nursing.

REF:   Page 9

1. While conducting the preoperative interview with Clair Conners, a patient scheduled for a septoplasty, the perioperative nurse learned that Clair was latex sensitive. Based on this knowledge, the nurse reviewed the pick/preference list and reassembled the surgical case cart setup to reflect this new information and change in care delivery. Which two phases of the nursing process are represented in the nurse’s actions?

a.Assessment and planningb.Assessment and implementationc.Planning and implementationd.Nursing diagnosis and intervention

ANS:  C

Planning is preparing in advance for what will or may happen and determining the priorities for care. Planning is based on patient assessment results in knowing the patient and the patient’s unique needs. Implementation is performing the nursing care activities and interventions that were planned and responding with critical thinking and orderly action. Implementation is the “work” of nursing.

REF:   Pages 8-9

1. The perioperative nurse implements protective measures to prevent skin or tissue injury caused by thermal sources. Successful accomplishment of this intervention would meet which of the following desired nursing outcomes?

a.The patient is free from signs and symptoms of chemical injury.b.The patient is free from signs and symptoms of electrical injury.c.The patient is free from signs and symptoms of radiation injury.d.All of the options are correct.

ANS:  D

Chemical and thermal sources used in surgery can cause skin and tissue burns (e.g., electrosurgery, povidine-iodine, radiation, lasers). The patient is free from signs and symptoms of chemical injury, radiation injury, and electrical injury are approved NANDA-International nursing diagnoses.

REF:   Pages 8, 10

1. The nursing diagnosis is derived from:

a.patient data retrieved from the nursing assessment.b.synthesized clues from the admitting diagnosis and surgery schedule.c.the approved NANDA-International list attached to the patient medical record.d.the admission form on the front of the chart.

ANS:  A

Nursing diagnosis is the process of identifying and classifying data collected in the assessment in a way that provides a focus to plan nursing care.

REF:   Page 7

1. Doreen Jasper, a preoperative admission for laparoscopic cholecystectomy with operative cholangiogram, was interviewed by her perioperative nurse in the preoperative intake lounge. Doreen’s weight on admission was 245 lb. After the assessment, the nurse returned to the OR and modified the standard plan of care by instituting risk reduction strategies that were derived from information from the preoperative assessment. A good example of this action would best be described by:

a.replacing the regular OR bed with a bariatric-specific OR bed.b.providing protective lead aprons for all staff during the procedure.c.writing the patient’s name, allergies, and body weight on the white board.d.administering antibiotics to the patient 1 hour before the incision.

ANS:  A

Planning is preparing in advance for what will or may happen and determining the priorities for care. Planning based on patient assessment results in knowing the patient and the patient’s unique needs so that alterations in events, such as positioning the patient on a bariatric-specific OR bed as opposed to a regular OR bed, can be readily accommodated. Replacing the OR bed with a larger OR bed is a nurse-sensitive preventive intervention that provides equipment based on patient need.

REF:   Page 8

1. Accurate documentation is an integral part of all phases of the nursing process. For this reason, perioperative nursing care documentation:

a.should not include technical care.b.must include a description of patient care delivered and patient response to that care.c.must be aligned with appropriate PNDS elements.d.will have PNDS integrated into all mandatory fields.

ANS:  B

Documentation of the nursing care given should include more than the technical aspects of care, such as the sponge count or the application of the electrosurgical dispersive pad. Nursing care documentation should be associated with the assessment and nursing diagnoses, with preestablished outcomes against which the appropriateness and effectiveness of care may be judged.

REF:   Page 10

1. When delegating a task, such as a preoperative skin prep, to an unlicensed individual, the perioperative nurse:

a.still retains responsibility and authority for the outcome of the task.b.must comply with the seven “rights” of delegation.c.transfers the authority to perform the task to a competent person.d.transfers the supervision of the competent person to another competent person.

ANS:  C

Delegation transfers to a competent person the authority to perform a selected nursing task in a selected situation according to the five “rights” of delegation. When the perioperative nurse delegates a task, he or she retains accountability for that delegation.

REF:   Page 10

1. The nursing excellence center for education at Sunny Shores Hospital developed standards for nursing advancement that would reflect high-level achievement of professional performance. They developed a clinical advancement ladder based on the leading skill and knowledge acquisition model and established worthy criteria for each level. Select the response that might best describe the highest level of achievement for a perioperative staff nurse.

a.CNOR credential, BSN, and chair of the nursing research committeeb.Published article in the Sunny Shores newsletter and 15 years’ service pinc.BCLS instructor and weekend EMT transportd.All of the options are correct.

ANS:  A

Achieving certification (certified nurse, operating room [CNOR]), pursuing lifelong learning, and maintaining competency and current knowledge in perioperative nursing are the hallmarks of the professional.

REF:   Page 4

1. Performance improvement activities in the perioperative practice setting are designed to promote:

a.cost savings by eliminating fines for near-misses and never events.b.customer satisfaction and loyalty.c.performance measurement activities.d.efficient, effective quality care.

ANS:  D

Performance improvement efforts encompass improvements in quality and effectiveness, based on ethical and economic perspectives. A performance measurement and improvement approach facilitates the delivery of safe, high-quality perioperative patient care.

REF:   Page 14

1. Perioperative nursing diagnoses and interventions are directed toward, and guided by, the tremendous risks for harm to the patient inherent in surgery and interventional procedures; therefore nursing actions can generally be categorized as:

a.therapeutic/restorative.b.preventive/protective.c.caring/comforting.d.advocating/justifying.

ANS:  B

Perioperative nurses possess a unique understanding of desired outcomes that apply to all patients. In contrast to some nursing specialties in which nursing diagnoses are derived from signs and symptoms of a condition, much of perioperative nursing care is preventive in nature, based upon knowledge of inherent risks to patients undergoing surgical and invasive procedures. Perioperative nurses identify these risks and potential problems in advance and direct nursing interventions toward prevention of undesirable outcomes, such as injury and infection.

REF:   Page 3

1. A registered nurse first assistant (RNFA) is considered an advanced practice nurse when he/she has achieved:

a.RNFA certification.b.clinical performance ladder level 4 or above.c.graduate degree in nursing (MSN).d.facility practice privileges.

ANS:  C

APNs must have graduate nursing education (at least a master’s degree).

REF:   Page 16

1. Emerging perioperative nursing roles are defined by the tremendous growth in science and technology combined with the increasing complexity of surgery and the interventional disciplines. An example of an emerging nursing role is:

a.sterile processing clinical specialist.b.general surgery service liaison.c.weekend resource nurse.d.Informatics nurse specialist.

ANS:  D

Informatics is another specialty in which some perioperative nurses are focusing. Pressures for more efficient management of fiscal, material, and human resources have stimulated the development of electronic information systems for diverse functions in perioperative patient care settings.

REF:   Page 16

1. The relationship between the Perioperative Patient Focused Model and the Perioperative Nursing Data Set (PNDS) is evidenced by their unique language and use of the nursing process to guide care. The most notable feature of their similarity is that the PNDS:

a.promotes standardized perioperative documentation.b.fosters research on best practices.c.begins with outcome statements.d.promotes standardized perioperative documentation and begins with outcome statements.

ANS:  C

Similar to the Perioperative Patient Focused Model, the PNDS begins with patient outcomes. Each outcome is defined and interpreted, and presents criteria by which to measure outcome achievement.

1. Surgical site infections (SSIs) are most often caused by gram-positive cocci and may arise from the patient’s own endogenous sources. The most typical causative microorganism cultured from SSIs is:

a.Staphylococcus epidermidis.b.Streptococcus pyogenes.c.Staphylococcus aureus.d.Enterococcus.

ANS:  C

The organisms most commonly found in postoperative SSIs include staphylococcal, enterococcal, pseudomonal, and streptococcal species. S. aureus is the most frequently identified organism.

REF:   Page 48

1. A swab of a fluid collection from an edematous, red, and separating postoperative wound is sent to the microbiology lab for culture, sensitivity, and Gram stain. The surgeon expects that the result will show a gram-positive coccus. This Gram stain designation is based on the:

a.ability to cause plasma to coagulate and form a microscopic clot.b.physical and chemical properties of the cell wall.c.formation of aerobic clustered spheres.d.appearance of a thicker and brownish colored cell wall.

ANS:  B

Gram stain is a procedure for staining bacteria; it is the first step in classifying and differentiating bacteria into two large groups (gram-positive and gram-negative) based on the chemical and physical properties of their cell walls. A gram-positive microorganism has a thicker cell wall than a gram-negative microorganism.

REF:   Pages 48-49

1. The hospital epidemiologist was alerted when several cultures had recently revealed suspicious similarities. He was concerned about two unrelated patients with similar abscesses in similar body regions. Susan Grant, a 72-year-old diabetic patient taking immunosuppressive medications for chronic Crohn’s disease, had an incision and drainage of a perianal fistula. Shawn Ames, a healthy 22-year-old college student and motocross racer, had an incision and drainage plus excision of a pilonidal cyst. Both patients cultured out a new subtype of S. aureus. Susan’s specimen results showed a significant colony growth of S. aureus plus differential growth of coagulase-negative S. epidermidis, while Shawn’s specimen was a high colony growth coagulase-positive, similar subtype of S. aureus. The epidemiologist charged his department to be alert for this S. aureus subtype and cross-check for trends. He was most concerned about one of these patients in particular and pulled up the medical record for review. Which patient may be at higher risk with the more virulent strain and why?

a.Susan because she is immunocompromised and elderly and has Crohn’s diseaseb.Shawn because he has pilonidal sinus tracts from sacral pressure caused by racingc.Susan because she has a mixed microorganism culture that is coagulase negatived.Shawn because he has a high microbial load that is coagulase positive

ANS:  D

Coagulase-positive staphylococci are more virulent or pathogenic than coagulase-negative staphylococci. S. aureus is hemolytic, parasitic, pathogenic, and coagulase positive. S. epidermidis is parasitic, less pathogenic, and coagulase negative. Virulence is the potency of a pathogen measured in the numbers required to kill the host.

REF:   Pages 48-49

1. While antibiotics have been credited with saving lives, misuse of antibiotics has contributed to the evolution of multidrug-resistant organisms (MDROs). Antibiotic use is prolific in the perioperative setting. Select the antibiotic application has evidence to support it as a best practice and not, potentially, a misuse of antibiotics.

a.Antibiotics given IV within 1 hour of the incision for every procedure with an incision or entered body systemb.Vancomycin paste applied to cut edges of the sternum in cardiac surgeryc.Tobramycin and methylmethacrylate bead implants into deep orthopedic incisions at risk for osteomyelitisd.Bacitracin ointment on a clean subcuticular sutured incision as part of the dressing

ANS:  A

Drug resistance from treatment-related causes is often the result of misuse (e.g., incorrect use, overuse, or underuse) of antibiotics. It is believed that 50% of all antibiotic use in the United States can be characterized by misuse in one form or another, and efforts to reduce surgical site infections include appropriate prophylactic antibiotic use in surgical patients. It is estimated that half of all antibiotic prescriptions written are not warranted. During antibiotic therapy, the patient may have retained a few resistant organisms. By natural selection, as the susceptible organisms are killed, the resistant organisms multiply and become predominant. Failure to perform sensitivity testing along with inappropriate dosing can contribute to resistance. Although some surgical complications are unavoidable, surgical care can be improved through decisions and subsequent care focusing on evidence-based practice recommendations. Research shows that delivering antibiotics to a patient within 1 hour of beginning surgery can dramatically decrease SSI rates, yet this practice is not followed in all situations.

1. The Centers for Disease Control and Prevention (CDC) has identified pathogens that could pose a threat to national and world security and safety through bioterrorism. Select the four most probable agents that could be used to cause mass transmission, mortality, panic, and social disruption.

a.Anthrax, tuberculosis, C. difficile, tularemiab.Smallpox, plague, botulism, tularemiac.Smallpox, monkeypox, avian influenza, anthraxd.Anthrax, H1N1 influenza, botulism, smallpox

ANS:  B

The potential for bioterrorism is a reality in today’s world. The CDC has identified agents that may pose a risk to national security because of their (1) easy dissemination or transmission from person to person, (2) potential to cause high mortality and have a major public health impact, (3) potential to cause public panic and social disruption, and (4) necessity for special action for public health preparedness.

REF:   Pages 64-66

1. Willard Braun was admitted to the ICU 3 weeks ago for heart failure and intractable atrial fibrillation. He has had diarrhea for 4 days that has cultured C. difficile. The transmission-based precautions sign on the door to his room alerts the staff to employ:

a.Contact Precautions with eye protection.b.both Standard Precautions and Contact Precautions.c.body substance isolation.d.droplet Precautions with standard isolation technique.

ANS:  B

In addition to Standard Precautions, Contact Precautions should be used for patients known or suspected to be infected or colonized with epidemiologically important organisms that can be transmitted by (1) direct contact, as occurs when the caregiver touches the patient’s skin, or (2) indirect contact, as occurs when the caregiver touches patient care equipment or environmental surfaces in the patient’s room.

1. Ernesto Horn was admitted to the emergency department (ED) with respiratory symptoms, facial and upper body abrasions, burns, and moist lesions after a small package, delivered to his office, exploded and sprayed him with dried powder and glass shards. In response to the reported mechanism of injury, the ED team sequestered him in a secluded area away from the rest of the patients. The team believed that this was highly suspicious of a bioterrorism event. The epidemiologist was called and the patient was transferred to a negative-pressure isolation room and placed on Standard, Contact, Airborne, and Droplet Precautions. Based on these actions, what microorganism agents might be suspected to be involved?

a.Plague and tuberculosisb.Smallpox and tuberculosisc.Ebola virus and anthraxd.Anthrax and smallpox

ANS:  D

Anthrax: Cutaneous lesions can occur from direct contact and inhalation from droplet, aerosolization. Use Standard Precautions with special attention to protection and containment of any draining wounds, inclusive of cutaneous lesions. Smallpox: Inhalation of droplets, droplet nuclei, aerosols, and direct or indirect contact; Standard, Droplet, Airborne, and Contact Precautions for patients with vesicular rash pending diagnosis. Avoid contact with organism while handling contaminated bedding. Wear protective attire to include gloves, gown, and N95 respirator.

1. Positive-pressure air handling systems with unidirectional flow of non-recirculated air from the ceiling to the floor are designed to:

a.create mild air turbulence to prevent dust from settling on surfaces.b.augment the oxygen-enriched environment with dust-free air.c.flow clean air over the patient and prevent corridor air intake.d.All of the options are correct.

ANS:  C

To control bioparticulate matter in the OR environment, ventilating air should be delivered to the room at the ceiling and exhausted near the floor and on walls opposite to those containing inlet vents. Airflow should be in a downward directional flow, moving down and through the location with a minimum of draft, to the floor and exhaust portals. Air pressure in the OR should be greater than that in the surrounding corridor; this is called “positive pressure” in relation to corridors and adjacent areas. This positive pressure helps maintain the unidirectional airflow in the room and minimizes the amount of corridor air (less clean area) entering the OR (more clean area).

REF:   Page 67

1. The design of the physical space within an OR attempts to minimize horizontal surfaces by placing cabinets flush with the wall. This prevents dust settling on multiple surfaces and decreases the areas that have to be monitored and cleaned. Another concern with horizontal surfaces is that air turbulence from staff movement and activity plus door movement, when it opens and closes, can:

a.mobilize resting dust from these surfaces.b.contaminate sterile areas.c.disrupt the unidirectional airflow.d.All of the options are correct.

ANS:  D

Movement and activity in the OR can create a turbulent airflow and may recirculate settled bacteria. Doors to ORs should be kept closed to maintain correct ventilation, airflow, and air pressure. Cabinets should be recessed into the wall if possible. For noncabinet shelving, open wire shelves are preferred because dust and bacteria do not accumulate, and air can circulate freely around shelf contents.

REF:   Page 67

1. All surgical patients present with the risk for hypothermia from a variety of factors inherent in the surgical experience. Hypothermia has been shown to be a factor that may place the surgical patient at risk for infection and delayed healing. Select the intervention that is an engineered control factor to protect the patient from hypothermia.

a.Surround the patient with a forced air–warming blanket and foil head covering.b.Set the ambient room temperature between 68° and 73° F and limit exposure.c.Line the OR bed with a circulating fluid mat and insert a rectal temperature probe.d.Cover and surround the patient with several warm bath blankets and change them at frequent intervals.

ANS:  B

Maintaining the ambient room temperature and limiting patient exposure is the first line of defense in protecting the patient from hypothermia. Temperatures in ORs should be maintained at 68° F (20° C) to 73° F (23° C).

REF:   Page 67

1. The mechanism of lethality (microbial death) with steam sterilization is achieved with this event.

a.Time, temperature, and steam pressureb.Reduced and limited mitosis within the bioburdenc.Saturated vaporization of the microbial cytoplasmd.Denaturation and coagulation of enzyme proteins

ANS:  D

Microorganisms are believed to be destroyed by moist heat through a process of denaturation and coagulation of the enzyme-protein system when steam sterilized. This fact is based on the theory that all chemical reactions, including coagulation of proteins, are catalyzed by the presence of water.

REF:   Pages 67-68

1. Within a steam sterilizer, at a temperature of 100° C (212° F), the water condensation and the steam are the same temperature. This scientific phenomenon is called ___________________ and will __________________.

a.Steam saturation; not kill microorganismsb.Steam distribution; promote microbial killc.Sterilization; kill all microorganisms to 106d.Saturated steam; kill microbes at 106

ANS:  A

When a cold item is introduced into the steam, some of the steam releases its latent energy to the object and changes back to liquid water. This phenomenon allows items to be heated much more rapidly in steam than in dry heat. The phenomenon of steam changing to liquid water is called condensation, and the steam and the liquid water are at a temperature of 100° C (212° F) when this occurs. At this point, the steam is said to be saturated. This 100° C (212° F) temperature is insufficient to kill microorganisms, however. To kill microorganisms, a saturation temperature of 250° F (121° C) is necessary.

REF:   Page 68

1. With the production of more steam in the sterilizer chamber, the pressure increases as well. The steam should contain little or no entrapped liquid water. Steam quality is the term that describes the amount of water mixed with the steam. The constitution of high-quality steam would be measured by:

a.97% or greater.b.100%.c.<3% of the mixture is liquid water.d.All of the values are correct.

ANS:  D

The higher the steam pressure, the higher the temperature. The steam is the sterilizing agent. Any compressed air remaining in the chamber mixes with the steam and lowers the steam temperature. This reduced-temperature steam is incapable of sterilization. Steam entering the sterilizer chamber should contain little or no entrapped liquid water. The term steam quality describes the amount of steam vapor and liquid water in the mixture. A steam quality of 100% indicates that no liquid water is present in the steam. A steam quality of 97% or greater (i.e., <3% of the mixture is liquid water) is recommended to achieve an efficient sterilization process.

REF:   Page 68

1. Sterilization prepares instruments to be used within, and on, sterile tissues. It kills vegetative microorganisms and endospores within a probability of 106. The process of decontamination prepares instruments to be:

a.handled without gloves and prepared for sterilization.b.free of bioburden and safely handled with gloves.c.clean at a high level of disinfection.d.None of the options are correct.

ANS:  B

The efficacy of the sterilization process depends in part on lowering or limiting the amount of bioburden present on the item to be sterilized. Items to be sterilized should be precleaned to lower the bioburden to the lowest possible level. Items that were soiled with blood or body fluids and that have only been cleaned may not have been sufficiently decontaminated to allow handling by workers not wearing protective attire. If such an item tolerates high-pressure water washing, it can be decontaminated further by processing through an unwrapped washer/disinfector cycle. It is then safe to handle. It is recommended that gloves be worn during preparation and wrapping until meticulous inspection has cleared the instruments to be handled without gloves.

REF:   Pages 68-69

1. Qualities of an effective packaging material must include these key characteristics. Select the three most important qualities.

a.Cost, good barrier, lint-free writable surfaceb.Good steam penetration and removal, good barrier, aseptic presentationc.Aseptic presentation, event-related sterility indicators, writable surfaced.Stackable in sterilizer/storage shelf, comparable cost, low toxicity

ANS:  B

To be effective, packaging material should have the following characteristics: allows for adequate steam penetration and removal; provides an adequate microbial barrier; resists tearing or punctures; has proven seal integrity (i.e., does not delaminate when opened and does not allow a reseal after opening); allows for aseptic delivery of package contents; is free of toxic ingredients and nonfast dyes; is low-linting; is cost-effective by cost and value analysis.

REF:   Page 71

1. The final step, after decontamination and before sterilization, is the prep, pack, and wrap process. The sterile processing technologist has taken the laparotomy set from the washer/decontaminator to prepare for sterilization. Select the most appropriate order that the instrument set must travel before reaching the steam sterilizer.

a.Air-dry, inventory, inspect, lubricate, assemble and string instruments, wrap and tapeb.Inspect, unlock locked clamps, count and string instruments, place indicators, wrap and tapec.Inspect, unlock locked clamps, string instruments, inventory, replace missing items, wrapd.Inspect, inventory against list, assemble, place integrators, wrap and tape

ANS:  D

The final step before sterilization for reuse includes instrument preparation and packaging. These activities occur in a clean area, separate from the area where decontamination occurred. Instruments are inspected carefully for cleanliness and functionality. Soiled instruments are returned for further cleaning. Instruments with movable parts are treated with a water-soluble lubricant solution that contains an antimicrobial agent to retard growth in the lubricant solution. Broken or worn instruments are set aside for repair. Instruments are assembled into sets according to set content lists prepared by perioperative nursing staff.

REF:   Page 71

1. Both sterilization and disinfection describe the elimination of microbial contamination and the achievement of a state suitable for patient care in select situations. However, disinfection differs from sterilization in that the process for disinfection uses:

a.contact Precautions as well as Universal Precautions.b.hospital-grade disinfectant/sterilants.c.semicritical medical devices used for ambulatory procedures.d.agents to disinfect and eliminate most, if not all, pathogenic microbes.

ANS:  D

Disinfection is defined as the process of eliminating many or all pathogenic organisms, except bacterial spores, from inanimate objects. In healthcare facilities, equipment is usually soaked in liquid chemicals for a specified period to achieve disinfection of the equipment or item. The disinfection process may destroy tubercle bacilli and inactivate hepatitis viruses and enteroviruses but usually does not kill resistant bacterial spores. The term disinfection also may refer to treatment of body surfaces that have been contaminated with infectious material. Chemicals used to disinfect inanimate objects are referred to as disinfectants. Chemicals used for body surfaces are known as antiseptics. The term germicide refers to any solution that destroys microorganisms.

1. An integrator is a multiparameter indicator designed to measure:

a.time and pressure.b.pressure, steam, and temperature.c.temperature, time, and presence of steam.d.sterility and pressure.

ANS:  C

Integrators are so named for their ability to integrate time, temperature, and the presence of steam. They reduce the risk of using an unsterile pack and may be used with numerous types of sterilization processes.

1. The evening before the procedure was scheduled, the central sterile processing department received two complete sets of an orthopedic spine fusion system that contained titanium-implantable instrumentation, four flexible coated retractor blades, and a sterilized internal paper inventory form. The sterilization instructions provided by the vendor representative recommended steam sterilization for the implants, but stated that the flexible coated blade retractors could not be exposed to temperatures higher than 220° F. The appropriate sterilization option for these instruments and devices would be:

a.hydrogen peroxide gas plasma sterilization for everything.b.steam sterilization for the implant sets and paper inventory form, hydrogen peroxide gas plasma for the retractors, wrapped separately.c.steam sterilization for the implant sets, hydrogen peroxide gas plasma for the retractors and paper inventory form, wrapped separately.d.steam sterilization for everything with a shortened dry time.

ANS:  B

Low-temperature hydrogen peroxide gas plasma sterilization should be used for moisture-sensitive and heat-sensitive items and when indicated by the device manufacturer. Cellulosic-based products, such as paper and linen, are not recommended for use with plasma systems because they tend to absorb the vapor and cause the sterilization cycle to abort.

1. The circulating nurse prepped the face, neck, and upper chest for a radical neck dissection. After removing the protective towels around the prep site, the surgical fellow applied the head drape and the rest of the patient was draped. During the preincision surgical time-out, the fire risk score was determined to be high. When the surgeon reentered the room, after leaving the room to scrub, and donned her gown and gloves, she noticed an area on the neck that did not look prepped. She asked for prep solution on a sponge and sponge forceps to complete the prep area, taking care not to moisten the head drape. After handing off the used sponge forceps she asked for the scalpel. What step was omitted in this process?

a.The new prep area was not given time to dry.b.The time-out should have been repeated with the surgeon scrubbed.c.The patient should have been reprepped and redraped with all new drapes.d.The scrub person should have given the surgeon a sterile towel to cover the unprepped area.

ANS:  A

Avoid pooling of preparation solution. If linens on the OR bed or the patient become soaked with solution, remove them from the area. Allow preparation solution to dry completely (3 to 5 minutes) before surgical drapes are applied. This may be incorporated as a time-out or “all-clear” announcement before proceeding with the draping process.

a.At the vagina and perineum; the nurse should check with the anesthesia provider before touching the patientb.At the incision site to the periphery of the abdomen only the nurse should begin and complete perioperative documentation of skin preparation including wound classificationc.At the cleanest area first and proceeds to less clean areas (abdomen then vagina/perineum); a skin assessment should be performedd.At the vagina and perineum first with urinary catheter insertion and then proceeds to the pelvic abdomen; a skin assessment should be performed

ANS:  C

Factors to be considered in skin disinfection are as follows: condition of the involved area, number and kinds of contaminants, general physical condition of the patient, characteristics of the skin to be disinfected, and patient allergies. The surgical principle followed when preparing the patient’s skin for surgery (“prepping”) is to prepare (“prep”) the cleanest area first and then move to the less clean areas (clean to dirty). The skin at the surgical site should be exposed and inspected before beginning the skin prep.

1. Closed gloving is the technique of choice for the initial donning of sterile gloves by the scrubbed team member; however:

a.it can only be used for the initial gloving.b.it requires two people to execute without contamination.c.there is a risk of contamination if the thumbs are not extended.d.All of the options are correct.

ANS:  A

The closed method of gloving is the technique of choice when initially donning a sterile gown and gloves. Because the cuffs of a sterile gown collect moisture, become damp during wearing, and are considered unsterile, the closed-gloving technique can be used only for initial gloving. Cuffs may not be pulled down over the wearer’s hand for subsequent gloving. For subsequent gloving, an alternative technique must be used, such as assisted gloving or open gloving.

REF:   Page 99

1. Which glove lubricant, used to facilitate easy donning, is considered a best practice?

a.Sterile talcum or corn starch powderb.Sterile petroleum-based oilsc.Sterile silicone filmd.None of the options is a best practice.

ANS:  D

The use of powder as a glove lubricant is not recommended because of three primary hazards: the potential for postoperative complication of powder granulomas; powder fallout from hands and gloves, which provides a convenient vehicle for dissemination of microorganisms throughout the OR; and the ability of powder to carry and disperse latex proteins, contributing to an increased latex sensitivity among healthcare workers and others.

Members of the scrub surgical team should use the following procedure to remove soiled sterile scrub attire: gowns, gloves, and then masks. Hands must be washed after removing soiled sterile attire.

REF:   Page 99

1. To protect the forearms, hands, and clothing from contacting bacteria on the outside of the used gown and gloves, members of the scrubbed surgical team should use the following procedure to remove soiled gowns and gloves. Which choice lists the appropriate first 3 steps in the removal of the sterile gown?

a.Wipe gloves clean, untie side gown closure, grasp gown at one shoulder seam.b.Wipe gloves clean, grasp gown at both shoulder seams, pull over and off arms.c.Unfasten gown back closures, grasp gown at one shoulder seam, pull down over both arms and gloves while everting glove cuffs.d.Grasp both gown shoulders, slide gown down over arms, grasp gloves inside gown sleeves and pull gown and gloves off together.

ANS:  A

Bring the neck and sleeve of the gown forward and off the gloved hand, turning the gown inside out and everting the cuff of the glove. Repeat the previous two steps for the other side. Keep arms and gown away from body while turning the gown inside out and discarding carefully in the designated receptacle.

REF:   Pages 100-101

1. Describe the best practice for aseptic removal of sterile gloves after removal of the sterile gown at the end of the procedure. Select the best practice to protect the wearer from cross-contamination.

a.Remove both gloves together using the gloved fingers of one hand to secure the everted cuffs of the other hand, turning both gloves inside out. Discard gloves in regular trash since they are inside out. Remove mask by the ties and wash hands.b.Using the gloved fingers of one hand to secure the everted cuff, remove the glove, turning it inside out. Discard appropriately. Using the ungloved hand, grasp the fold of the everted cuff of the other glove and remove the glove, inverting the glove as it is removed. Discard in biohazard trash. Remove mask by the ties and discard. Wash hands.c.Both practices are appropriate.d.Neither practice is appropriate.

ANS:  B

Using the gloved fingers of one hand to secure the everted cuff, remove the glove, turning it inside out. Discard appropriately. Using the ungloved hand, grasp the fold of the everted cuff of the other glove and remove the glove, inverting the glove as it is removed. Discard appropriately. After leaving the restricted area, remove the mask by touching the ties or elastic only. Discard in the designated receptacle. Wash hands and forearms.

1. The surgical hand scrub is designed to render the hands, nails, and arms:

a.surgically clean.b.free of transient microorganisms, dirt, and skin oils.c.coated with residual antimicrobial residue to prevent microbial regrowth.d.All of the options are correct.

ANS:  D

The purposes of surgical hand hygiene are as follows: to remove dirt, skin oil, and transient microorganisms from the nails, hands, and forearms; to reduce the resident microbial count to as near zero as possible; and to leave an antimicrobial residue on the skin to prevent regrowth of microbes for several hours. The skin can never be rendered sterile, but it can be made surgically clean by reducing the number of microorganisms present.

REF:   Page 93

1. Decontamination of the hands can be done by a variety of methods. The Joint Commission (TJC) states that a thorough handwash with an antimicrobial agent may be as effective as the traditional surgical scrub using a brush or sponge. Facility infection control procedures govern the selection of materials and the methods used for surgical hand hygiene. Select the best practice for surgical hand hygiene.

a.Alcohol-based hand rubb.Anatomic counted strokes with 4% chlorhexidine gluconate brushc.Anatomic timed strokes with povidine iodine sponged.Any of the options with an antimicrobial hand wash

ANS:  D

For the traditional, standardized surgical scrub, individually packaged disposable brushes and sponges or synthetic sponges without a brush may be used. The use of synthetic sponges in place of brushes has gained wide acceptance, especially where long and repeated scrubbing may be traumatic to the skin. A thorough handwash with an antimicrobial agent may be as effective as the traditional surgical scrub using a brush or sponge. An anatomic scrub, using a prescribed amount of time or number of strokes plus friction, is employed for effective cleansing of the skin. The prescribed number of strokes with a brush is usually 30 strokes to the nails and 20 strokes to each area of the skin. When using the timed approach, the institution’s policies and procedures should be followed. A standardized procedure for handwashing should be established and followed within the healthcare setting. This may be accomplished by a surgical scrub or with the use of an approved hand rub agent.

REF:   Page 93

1. Which of the following choices reflects the appropriate order of four of the steps in preparing for the surgical hand scrub procedure?

a.Wash hands and wrists, remove jewelry, replace mask and eye protection, contain hair.b.Contain hair and earrings in hat, wash hands and clean under nails, place mask and eye protection, remove jewelry.c.Remove jewelry, contain hair, don fresh mask and eye protection, wash hands and forearms.d.Don fresh mask, contain hair, place eye protection, clean under nails.

ANS:  C

A standardized procedure for handwashing should be established and followed within the healthcare setting. Remove all jewelry, including rings, watches, and bracelets, from the hands and forearms. Cover all head and facial hair. Don a surgical mask. If other personnel are at the scrub sink, a surgical mask should be worn in the presence of hand scrub activity. Protective eyewear, such as goggles with side shields or a full-face shield, should be adjusted to ensure clear vision and to avoid lens fogging. If visibly soiled, wash hands and forearms with soap and running water immediately before beginning the scrub procedure.

REF:   Pages 93-94

1. If a sterile glove becomes contaminated during the procedure, the best practice for corrective action is:

a.reglove with open-glove or assistive glove technique.b.reglove with closed-glove technique.c.remove gown and gloves and regown and reglove.d.place a new sterile glove over the contaminated glove.

ANS:  A

Cuffs may not be pulled down over the wearer’s hand for subsequent gloving. For subsequent gloving, an alternative technique must be used, such as assisted gloving or open gloving.

REF:   Page 99

1. In several studies, it was determined that the risk of contamination and subsequent infection to the wearer can be reduced by wearing two pairs of sterile surgical gloves, as opposed to wearing one pair. Select the correct statement that refers to double gloving in terms of a best practice.

a.The Centers for Disease Control and Prevention (CDC) endorses double gloving for all surgery and invasive procedures.b.Wearing two glove layers permits regloving using the closed-glove technique for a contaminated glove.c.Wearing a glove liner between both layers of gloves may eliminate the risk of perforation to the inner glove, protecting the wearer from sharps injury.d.The AORN publication titled Recommended Practices for Prevention of Transmissible Infections in the Perioperative Practice Settingrecommends the double-glove procedure during invasive procedures.

ANS:  D

The AORN publication titled Recommended Practices for Prevention of Transmissible Infections in the Perioperative Practice Setting recommends the double-glove procedure during invasive procedures because of several issues based on a systematic review of the literature.

1. Sterile surgical drapes are used to create the sterile field, protecting the patient from endogenous and exogenous sources of contamination. Of the characteristics listed, which are essential to maintaining the sterile field?

a.Provide barrier protection from microorganisms, fluid, and particulate matterb.Limit environmental impact and flammabilityc.Ensure a fiscally responsible cost/benefit ratio and reduce glared.All of the options are important.

ANS:  A

Sterile drapes provide a barrier to microorganisms, particulate matter, and fluid while protecting the patient from both exogenous and endogenous sources of contamination.

REF:   Page 104

1. When applying sterile drapes to create the sterile field on the patient, which of the following principles is most important?

a.The circulating nurse should monitor the scrub person’s gowned arms when reaching over the unsterile parts of the patient.b.Gently shake and fan out the drapes to open up the folds before approaching the patient.c.Drape the patient starting with the incision area and proceeding to the periphery.d.All of the options reflect violations of sterile technique.

ANS:  C

The draping procedure should begin at the area of the intended incision and proceed outward to the periphery. Always drape from a sterile area to an unsterile area by draping the near side first. Never reach across an unsterile area to drape. When draping the opposite side of the OR bed, go around the bed to drape.

1. The transplant team received the liver from the procurement team moments after it arrived by medical air lift. The OR was ready with a scrubbed team of a circulating nurse, scrub person, transplant surgeon, and surgical resident and with a sterile back table set up and counted to prepare the liver for transplant. As the surgeon began to dissect out the liver vessels, he realized that the liver could reasonably serve two recipient patients and he had another suitable donor candidate. The surgeon was aware that all of the available OR rooms were blocked and running until midnight, and the second patient could not be scheduled until this case was finished. As he carefully segmented and split the liver, the second patient was contacted to come to the medical center. The anesthesia provider transported the original intended recipient patient into the room and proceeded to prepare and induce the patient with a general anesthetic. The circulating nurse suddenly realized the sterile technique violation dilemma after the patient was asleep. Which option best reflects appropriate sterile technique and the best care for both patients?

a.The patient should have been taken to a second available OR, not the room with the liver dissection underway, since it was being split for two patients.b.The patient should have been held in preoperative holding until the liver was split and the second segment placed back into the cooler.c.The back table should have been covered with sterile drapes and moved to a second available room.d.The surgeon should proceed with splitting the liver, replacing the segment for the second patient back into the cooler, and storing the cooler in the back of the OR for the second transplant patient, whose procedure will follow in the same OR.

ANS:  B

The presence of the patient in the OR while the liver is being split to provide a transplant organ for a second patient is a sterile technique violation as the probability of contamination of the liver segment from microbes from the first patient could affect the segment to be transplanted to the second patient. All surgical patients are potentially infected with bloodborne or other infectious material. Contamination in the OR can occur from various sources. The patient, healthcare workers, and inanimate objects are all capable of introducing potentially infectious material onto the surgical field. The patient should be provided a clean, safe environment.

1. Effective instrument decontamination is dependent on a particular sequence designed to lower bioburden to the lowest level. Number the steps below to reflect the correct order of processing a basic set of laparotomy instruments through decontamination.

_____ a. During surgical procedure, wipe instruments with sterile water.

_____ b. Transport in closed container to decontamination area.

_____ c. Employ ultrasonic washer.

_____ d. Preclean with neutral enzyme agent in leakproof container in procedure room.

_____ e. Disassemble and unlock all instruments; place heavy instruments on bottom.

_____ f. Rinse with cold water in deep sink.

_____ g. Remove and discard all disposable sharps.

_____ h. Place in automated instrument washer/decontaminator.

ANS:

1 = A

2 = G

3 = E

4 = D

5 = B

6 = F

7 = H

8 = C

Items to be sterilized should be precleaned to lower the bioburden to the lowest possible level. Instruments should be kept as free as possible from gross soil and other debris during the surgical procedure. Throughout the surgical procedure, the scrub person should wipe used instruments with sponges moistened with sterile water. Initial decontamination should begin immediately on completion of the surgical procedure. All instruments that can be immersed are disassembled, and box locks are opened to allow solution to contact all soiled surfaces. These instruments should be placed in a basin, solid-bottom container system, or bin with a lid. An enzyme solution, foam, or spray can be added to the instruments to begin the process of breaking down any proteinaceous materials that may remain on the instruments. Soiled instruments should be within leakproof containers or trays inside plastic bags when they are transported from the OR for cleaning and decontamination. In the decontamination area, pretreatment involves an initial cold water rinse with tap water or a soak in cool water with a protein-dissolving and blood-dissolving enzyme. After completion of this pretreatment, the instruments should be processed in an automated device, and washed by hand if an automated device is not available Automated processing is completed with the use of washer/sanitizers or washer/decontaminators. The ultrasonic cleaning process is designed to remove fine soil from crevices and box-lock areas of instrumentation. It should be used only after gross debris has been removed from instruments.

MULTIPLE CHOICE

1. The liver, pancreas, and spleen share many similarities. Select the statement about these organs that is true.

a.All three are solid organs and very vascular.b.All three are metabolic organs.c.All three organs have terminal attachments to the duodenum.d.All of the options are false.

ANS:  A

All three organs are solid (not hollow or collapsible) organs. A pathologic condition in the liver, biliary tract, pancreas, or spleen often requires surgical intervention. These organs are highly vascular and control many metabolic and immune functions of the body.

REF:   Pages 357-361

1. The functional units of the liver are the lobules. The functional cells of the liver are the ______________ and they manufacture _______________.

a.Kupffer cells; phagocytesb.sinusoid cells; lymphocytesc.hepatocytes; biled.portal triad cells; ductal epithelium

ANS:  C

Lobules are the functional units of the liver. Each lobule contains a portal triad that consists of a hepatic duct, a hepatic portal vein branch, and a branch of the hepatic artery, nerves, and lymphatics. The hepatic cords consist of numerous columns of hepatocytes—the functional cells of the liver. The hepatic sinusoids are the blood channels that communicate among the columns of hepatocytes. The sinusoids have a thin epithelial lining composed primarily of Kupffer cells—phagocytic cells that engulf bacteria and toxins. Bile is manufactured by the hepatocytes.

1. The liver is essential in the metabolism of carbohydrates, proteins, and fats, generating nutrient stores of which substance that supplies energy sources to the brain and body?

a.Carbohydrate glucose substrateb.Glycogenc.Serum glucosamined.Bile salts

ANS:  B

The liver is essential in the metabolism of carbohydrates, proteins, and fats. It metabolizes nutrients into stores of glycogen, used for regulation of blood glucose levels and as energy sources for the brain and body functions.

REF:   Pages 357-358

1. The biliary system (also called the biliary tree) drains bile from the gallbladder to the ampulla of Vater. The primary function of the gallbladder is to:

a.manufacture bile.b.convert bile salts into bile enzymes.c.store and concentrate bile.d.contract to secrete bile into the hepatic duct.

ANS:  C

The gallbladder, which lies in a sulcus on the undersurface of the right lobe of the liver, terminates in the cystic duct (Figure 11-3). This ductal system provides a channel for the flow of bile to the gallbladder, where it becomes highly concentrated during storage. The liver produces about 600 to 1000 ml of bile each day. The gallbladder’s average storage capacity is 40 to 70 ml. As the musculature of the gallbladder contracts, bile is forced into the cystic duct and through the common duct. As the sphincter of Oddi in the ampulla of Vater relaxes, bile is released, flowing into the duodenum to aid in digestion by emulsification of fats.

1. While the pancreas’ function is carbohydrate metabolism with the production of insulin and digestive enzymes, the spleen’s function is primarily ___________ with the production of _______________.

a.immunologic; leukocytesb.metabolic; granulocytesc.anabolic; plasma cellsd.as a blood reservoir; phagocytes

ANS:  A

The spleen has many functions. Among them are defense of the body by phagocytosis of microorganisms, formation of nongranular leukocytes and plasma cells, and phagocytosis of damaged red blood cells. It also acts as a blood reservoir. The pancreas contains groups of cells, called islets, or islands, of Langerhans, that secrete hormones into the blood capillaries instead of into the duct. These hormones are insulin and glucagon, and both are involved in carbohydrate metabolism.

1. Matthew Ryan, a 9-year-old boy, is admitted to the emergency department for a sledding accident, when he lost control of his sled and crashed into a tree. He is pale and in pain; his abdomen is tender and firm to palpation. The CT scan suggests rupture of the spleen with internal bleeding. Matthew’s scheduled surgery will most probably be a(n):

a.laparoscopic splenic resection with sutured mesh overlay.b.open splenic lobectomy with vascular ligation.c.open total splenectomy.d.open splenic repair with sutured anastomosis and argon plasma coagulation vessel sealing.

ANS:  C

Splenectomy is removal of the spleen. It is performed for multiple reasons, including trauma to the spleen. Contraindications to laparoscopic splenectomy include severe portal hypertension, uncorrectable coagulopathy, severe ascites, extreme splenomegaly, extensive adhesions, and most traumatic injuries to the spleen. For these patients, an open approach is indicated.

1. Open common bile duct (CBD) exploration may be indicated in some cases where:

a.the patient has undergone prior biliary surgery.b.a positive cholangiogram shows a CBD obstruction during an open cholecystectomy.c.laparoscopy technology is not available.d.All of the options are correct.

ANS:  D

With the advent of endoscopic, percutaneous, and laparoscopic techniques (Figure 11-13), open exploration of the common bile duct is rarely performed. When these newer methods are not available, when they are not possible because of prior surgery, or when an open procedure is otherwise necessary, open common bile duct exploration is performed.

1. An example of a potential risk associated with pneumoperitoneum would be:

a.tachycardia caused by peritoneal irritation from the CO2.b.CO2 absorption into the peritoneal capillaries, causing decreased oxygen saturation.c.bradycardia from CO2 pressure lower than 15 mm Hg.d.gas embolus into an exposed blood vessel during the procedure.

ANS:  D

CO2 is the gas of choice for pneumoperitoneum. The perioperative nurse should set the insufflation unit to a maximum pressure of 15 mm Hg. Pressure higher than 15 mm Hg may result in bradycardia or a change in blood pressure, or may force a gas embolus into an exposed blood vessel during the operative procedure.

1. Steven Morganstein, a 51-year-old male with hepatobiliary disease, is scheduled for surgery. The perioperative nurse, during the preoperative assessment, questions and examines the patient for signs and symptoms of jaundice, petechiae, and lethargy and:

a.reviews his chart for bleeding and coagulation times and the platelet count.b.asks Steven his blood type and when he last donated blood.c.palpates Steven’s abdomen for left upper quadrant tenderness and liver margins.d.reviews the findings of his endoscopic retrograde cholangiopancreatoscopy (ERCP).

ANS:  A

The patient with hepatobiliary disease may have extreme jaundice, urticaria, petechiae, lethargy, and irritability. Depending on the extent of the disease, bleeding and coagulation times may be increased and the platelet count decreased, contributing to intraoperative concerns with achieving hemostasis.

1. Luanne Williamson, a 39-year-old, 248-lb mother of 4 children, is assisted with transfer from a transport vehicle to the OR bed for laparoscopic cholecystectomy, operative cholangiogram, and possible common bile duct exploration. The perioperative nurse determined that Luanne is at risk for positional injury related to her size and the positional requirements and OR bed manipulations required for this procedure. An appropriate nursing implementation for positioning this patient would be to:

a.place two safety belts over the thighs and lower legs to prevent the patient from sliding out of position when the surgeon tilts the table for better exposure and access.b.place a positioning lift under the lower right side of the chest to elevate the lower rib cage for exposure and access to the viscera in the right upper quadrant of the abdomen.c.abduct the patient’s right arm on an armboard at less than 90 degrees to allow an assistant to stand near the patient’s right upper quadrant and retract the liver with a wide Deaver retractor.d.place two safety belts over the thighs and lower legs to prevent the patient from sliding out of position when the surgeon tilts the table for better exposure and access, and place a positioning lift under the lower right side of the chest to elevate the lower rib cage for exposure and access to the viscera in the right upper quadrant of the abdomen.

ANS:  D

For biliary surgery, the patient is placed in supine position. The patient’s arms are usually placed on padded armboards with the palms up and fingers extended. Armboards are maintained at less than a 90-degree angle to prevent brachial plexus stretch. A small positioning aid may be placed under the lower right side of the thorax to elevate the lower rib cage, providing better exposure and access to the viscera in the right upper quadrant of the abdomen. A lateral tilt of the OR bed may be used in combination with reverse Trendelenburg’s position for procedures such as laparoscopic cholecystectomy.

He had an ERCP 1 week ago and, based on the findings, was scheduled for surgery at the comprehensive cancer center, where he works in the interventional endoscopy unit. He is aware of the poor prognosis for this disease and his nurse has recorded his nursing diagnosis as: Anxiety related to impending surgical procedure, perioperative events, and surgical outcome. An appropriate nursing action for Alfred would be to:

a.encourage verbalization of his fears and reinforce the standardized age-appropriate coping mechanisms.b.describe for him the steps of the operative procedure.c.offer emotional reassurance by using touch, assisting him to a position of comfort on the OR bed, and offering warm blankets (thermal comfort).d.share with Alfred his nursing diagnosis and reinforce the desired nursing outcome related to anxiety.

ANS:  C

When patients are anxious, the perioperative nurse should speak slowly and clearly, using terminology the patient can understand. Offer emotional reassurance by using touch, assisting the patient to a position of comfort on the OR bed, and offering warm blankets (thermal comfort).

1. Jan Stuyvesant, a perioperative nurse, was the scrub person during a robotic-assisted laparoscopic cholecystectomy. She locked the robotic endoscissor into the adaptor on the robotic arm and positioned the tip end into the trocar port in order for the surgeon to dissect the cystic duct and artery, while the surgical assistant placed the clips on the cystic duct and artery. As she reached across the sterile field to insert the cholangiocatheter through the port, the anesthesia provider accidentally made contact with the distal end of the catheter as he stood up to reach the monitor controls. The contaminated end of the catheter touched the endoscopic clip applier, the endoscissor connector that the surgeon was using, the glove of the assistant, and Jan’s gown sleeve. The surgeon ordered everyone to change their gown and gloves and covered the port area with a sterile towel. What was the rationale for the surgeon to continue to dissect and not change his attire?

a.The tip of the dissector that was in the patient’s abdomen was not contaminated.b.The surgeon planned to remove the dissector after he finished dissecting and then dispose it.c.The surgeon’s gown was not touched, just the dissector connection to the robotic arm.d.The surgeon was not in contact with the sterile field because he worked from the robotic console.

ANS:  D

The surgeon manages the robotic system from a console away from the operative field. With current robotic systems, the surgeon sits at an operative console with three-dimensional imaging and handheld controls. Movement of the controls follows the movement of the instrument’s tip. Robotic arms function just like a surgeon’s hands.

1. Joanne Grizwald, a 24-year-old woman with type 1 diabetes who is in end-stage kidney failure, is scheduled for a combined kidney-pancreas transplant. She is relatively healthy and at normal weight for her height in spite of her disease process. Her bleeding time and coagulation parameters are within normal limits. The circulating nurse has set up the autotransfusion system, verified Joanne’s blood type, and crossmatched blood availability. The scrub person, while organizing the sterile back table, identified several instruments that she will not need. She organizes those instruments on the most distant part of the back table. What instruments is the scrub person unlikely to need during this procedure?

a.Based on Joanne’s coagulation status, excess bleeding is not expected to be an issue.b.Hemostasis will be achieved by the use of microfibrillar collagen agents that do not leave electrosurgical eschar (burned tissue) on the bleeding surfaces, thereby reducing the chance of infection.c.Any excess bleeding will be removed and returned to the patient through the autotransfusion system.d.The transplant procedure is an open approach and laparoscopic instruments (the insulated electrosurgical-adapted scissors, graspers, and the endoscopic suction tips) are not needed.

ANS:  D

Pancreatic transplantation is the implantation of a pancreas from a donor into a recipient for patients with type 1 (formerly known as juvenile-onset) diabetes. Options for pancreatic transplant include a pancreas transplant alone (PTA), an option chosen for patients with functioning kidneys, or a simultaneous pancreas-kidney transplant (SPK). The whole-organ pancreatic transplantation procedure is performed through an oblique incision opposite the side of the renal transplant in the lower abdominal quadrant.

1. During an emergent total open splenectomy on a patient with blunt force trauma to the abdomen, the circulating nurse and anesthesia provider noticed rust-colored urine in the urinary collection container. They had just hung the third unit of whole blood. What nursing action is the first priority?

a.Send a sterile urine sample for stat cytologic studies.b.Notify the scrubbed team of the urine color change and check the bladder for trauma.c.Stop the blood transfusion.d.Check the blood unit for patient-specific identification and expiration date.

ANS:  C

The first response is to stop the transfusion; the surgical team had just started transfusing another unit of blood and the probability of a transfusion reaction is likely. There would be no immediate harm to the patient from stopping the blood transfusion. Instead, the surgical team should increase the IV flow rate of saline or lactated Ringer’s. When additional blood or blood products are required, the perioperative nurse communicates with blood bank personnel so that products are readily available, and then in conjunction with the anesthesia provider completes the required steps to verify blood/blood products before transfusion. Autologous blood or donor-directed blood products may be used in elective procedures involving the liver, pancreas, spleen, and biliary tract. Cell saver devices may be used.

1. What technologic characteristic of robotic surgery provides a superior indication for robotic-assisted laparoscopic cholecystectomy?

a.The surgeon controls two instruments plus a camera while an assistant suctions and retracts.b.Bladeless robotic trocars minimize entry injury and inadvertent hemorrhage.c.The magnified three-dimensional picture may reduce bile duct injuries during dissection.d.Robotic stapler and suture devices promote intracorporeal anastomotic techniques.

ANS:  C

Robotic surgery enables surgeons to perform more advanced and complex procedures. The view of the ductal anatomy is subjectively superior with robotic surgery because of the magnified three-dimensional picture, which may reduce bile duct injuries.

1. Marvin Townsend is a 29-year-old man with paraplegia caused by spinal cord injury from a diving accident 4 years ago. He is transported into the trauma ED after being hit by a car as he was crossing the street in his wheelchair. He has a possible rupture of his liver and is scheduled for surgery. The perioperative nurse, on response to the trauma call, meets him in the ED to conduct a preoperative assessment and prepare for his procedure. Marvin tells the nurse that he is latex-sensitive because he was told that as a spinal cord injured person he should always be considered latex-allergic. An appropriate risk reduction strategy for Marvin’s latex sensitivity/allergy would be to:

1. Jarvin Patel, a 42-year-old woman from Mumbai, India, is visiting her daughter and new grandson. She is a devout follower of Hindu religious practices and has been diagnosed with splenomegaly, possibly from idiopathic thrombocytopenia. Jarvin is scheduled for a total splenectomy. During the preoperative assessment, the perioperative nurse, an observant Hindu herself, is concerned about the possibility of significant bleeding because of Jarvin’s coagulopathy and the need for hemostatic agents that are typically used to stop bleeding. Many of these products are manufactured from bovine source products and it would be in conflict with Jarvin’s religion to use products from a cow. An appropriate risk reduction strategy for selection of hemostatic agents that would not be in conflict with Jarvin’s belief system would be:

a.substitute absorbable gelatin and oxidized collagen products; soak in thrombin.b.substitute absorbable gelatin and oxidized collagen products; use high ESU settings.c.substitute absorbable gelatin and oxidized collagen products; use regular ESU settings.d.substitute microfibrillar collagen soaked in thrombin; add epinephrine 1:1000.

ANS:  C

These hemostatic products do not contain bovine products: absorbable gelatin, powder, or compressed forms (Gelfoam); purified porcine gelatin, beaten, dried, and heat-sterilized;and oxidized cellulose (Surgicel, Surgicel Nu-Knit); absorbable oxidation product of cellulose. These products are manufactured from bovine products: absorbable collagen (Collastat, Superstat, Helistat); bovine collagen origin. Collagen activates the coagulation mechanism, aggregation of platelets; microfibrillar collagen (Avitene, Instat), hydrochloric acid salt of purified bovine corium collagen; thrombin enzyme extracted from bovine blood.

1. The donor liver OR is prepared for an open laparotomy procedure with basic laparotomy and vascular instruments and accessories. A second sterile instrument table is set up to receive and prepare the procured liver. Select the additional instruments and accessories needed on the donor organ preparation table.

a.vascular instruments, silk sutures and ties, sterile ice, flushing solution, and slush machine.b.flushing solution, ice chest, sterile ice, powered sternal saw, and long Kocher clamps.c.culture tubes, Wisconsin University forceps, Deaver retractors, and slush machine.d.toothed forceps, vessel loops, two sterile plastic draw-string bags, and flushing solution.

ANS:  A

The donor OR is prepared for a major laparotomy procedure. Basic instrumentation and equipment includes a basic laparotomy set, cardiovascular instruments, power sternal saw, and nephrectomy instruments. A sterile, draped, medium-size instrument table is needed for preparation of the liver away from the main sterile field and instrument tables. The procurement team provides special Collins solution for flushing the organs, sterile plastic containers and ice chests for organs, and in situ flush tubing. The liver is generally placed in two plastic Lahey bags immediately after procurement.

1. The recipient liver OR is arranged for a major laparotomy and vascular procedure with customized instruments, supplies, and sutures according to the transplant surgeon’s preference. In addition to the general patient care accessories, equipment, and supplies needed for any large surgery, also included are intraoperative laboratory testing and an autotransfusion system. Describe the boundaries of the surgical skin prep for the patient about to receive a liver transplant.

a.From neck to midthigh; midaxillary line to midaxillary lineb.From nipple line to pubis; bedline to bedlinec.From the neck to midthigh; bedline to bedlined.From nipple line to midthigh; midaxillary line on the patient’s left side, and bedline on the right

ANS:  C

Each transplant surgeon has preferred instruments, supplies, and sutures. The patient is placed supine with knees slightly flexed and padded. An indwelling urinary catheter is inserted after induction of anesthesia. The patient is prepped from the neck to midthigh, bedline to bedline. Prep solution should not pool at the bedline or wet the sheets on the OR bed. Fire safety precautions for prep solutions must be followed.

MULTIPLE RESPONSE

1. Both Maryanne and Charles Rigler had surgery 6 days ago. Charles had a living-related donor liver transplant and Maryanne, the matched donor, provided a segment of her healthy liver for her husband. They have both recovered as expected and are preparing for discharge. They are concerned about who will be the primary caregiver, since they are both recovering at the same time and rate. They also realize that they will need clear and realistic instructions and support because of their unique situation. They are most concerned about incision care, side effects that could mean complications, nutrition, and activity restrictions and escalation. An appropriate risk reduction strategy for Maryanne and Charles would give first priority to (select all that apply):

a.secure an order for social services consult.b.secure an order for a physical rehabilitation plan.c.provide Maryanne and Charles with the standard discharge education with emphasis on their concerns.d.elicit their abilities to provide for themselves and their resources of support.

ANS:  C, D

The patients should be included in the decision-making about their post discharge care and have the opportunity to discuss, with the nurse or other healthcare services, their resources for support in order for them to mutually make a decision about professional assistance and needs that are in the best interest of their recovery. After receiving their discharge expectations, they can better compare the expectations and events with their capabilities and resources. The general discharge instructions for liver surgery patients include the following: keep the incision area clean and dry; solid foods should be added gradually; chew solid foods well, and avoid gulping, eating fast, or swallowing large and bulky portions; avoid carbonated beverages for 3 to 4 weeks to help prevent gas bloating; eat small, frequent meals; follow medication instructions and conduct medication verification; increase exercise gradually to return to normal activities of daily living; exercise regularly; and make an appointment for follow-up care with the surgeon.

1. Number the sequence of critical steps for receiving, checking, and verifying the transplant organ.

____ A. The organ arrives at the OR.

____ B. The circulating nurse and a second RN verify the organ tag with the preliminary crossmatch report to ensure the following match: the recorded ABO type of the recipient is the same or is compatible with the recorded ABO type of the donor, the UNOS (United Network for Organ Sharing) number on the organ is the same as the UNOS number on the Preliminary Crossmatch Report. The two RNs then identify the patient according to hospital policy and sign the Transplant Verification form.

____ C. The transplant surgeon verifies that the UNOS number on the Preliminary Crossmatch Report is the same as the UNOS number on either the organ container or the paperwork provided and verifies the compatibility of the organ and the patient by ABO blood type. The transplant surgeon signs the Transplant Verification form.

____ D. The Transplant Verification form and Preliminary Crossmatch Report are placed on the permanent part of the patient’s medical record.

____ E. Crossmatch and ABO reports from the human leukocyte lab and blood bank are received.

____ F. The Transplant Verification form (deceased donor) is attached to the record.

____ G. Once the patient is taken into the OR, a time-out is taken with the OR team according to OR policy and procedure.

____ H. The OR charge nurse verifies the recipient’s preliminary crossmatch and ABO report.

____ I. The circulating nurse identifies the box with a recipient patient label.

1 = E

2 = H

3 = A

4 = I

5 = B

6 = C

7 = G

8 = D

9 = F

Before the transplant surgical procedure, a process of nine checkpoints is implemented to ensure identity and matching between the organs/tissues of the donor and the recipient. Before the patient enters the OR, the following must occur: (1) Once a transplant has been posted, Preliminary Transplant Crossmatch Reports are faxed from the human leukocyte antigen (HLA) lab to the transplant OR. The blood bank will fax ABO reports. (2) The OR charge nurse verifies
