CNOR Perioperative Nursing Certification Exam — Questions and Answers

Question 1: What is the primary goal of maintaining sterile technique in the operating room?

To prevent contamination of the surgical site (Correct answer)
To protect the surgical team from exposure to bodily fluids
To enhance the speed of the surgical procedure
To minimize the need for postoperative antibiotics

Correct answer: To prevent contamination of the surgical site

The primary goal of maintaining sterile technique in the operating room is to prevent the introduction of microorganisms into the patient's surgical wound. By minimizing the risk of contamination, sterile technique significantly reduces the likelihood of surgical site infections (SSIs), which can lead to serious complications and prolonged recovery for the patient.

Question 2: What is the primary rationale for using prefilled, pharmacy-prepared syringes in the perioperative setting?

To eliminate the need for medication labeling on the sterile field
To reduce the risk of medication preparation errors at the point of care (Correct answer)
To allow faster administration during emergencies
To decrease the number of medications needed on the sterile field

Correct answer: To reduce the risk of medication preparation errors at the point of care

Pharmacy-prepared syringes undergo standardized preparation and labeling processes that reduce the risk of errors compared to bedside preparation.

Question 3: Which statement about documenting use of an electrosurgical unit (ESU) is consistent with AORN guidelines?

Document the type of ESU, settings used, dispersive electrode placement site, and skin condition under the electrode (Correct answer)
The biomedical technician documents all ESU parameters
Only document ESU use if a skin burn occurs
Document only the generator model number

Correct answer: Document the type of ESU, settings used, dispersive electrode placement site, and skin condition under the electrode

AORN requires documentation of ESU type, power settings, dispersive electrode location, and skin condition at the electrode site before and after use.

Question 4: What action should the perioperative nurse take upon discovering a medication labeling error on the sterile field?

Document the error only at the end of the case
Relabel the container and continue using the medication
Remove the mislabeled medication from the field immediately, discard it, and replace it with a correctly labeled item (Correct answer)
Inform the surgeon but continue using the medication

Correct answer: Remove the mislabeled medication from the field immediately, discard it, and replace it with a correctly labeled item

A mislabeled medication is a safety hazard and must be removed and discarded immediately; it should never be relabeled and reused because the contents cannot be verified.

Question 5: What role does ethics play in Anesthesia Basics practice?

It only matters for legal compliance
Ethics is optional in professional settings
It guides professional conduct and protects stakeholders (Correct answer)
It only applies to managers

Correct answer: It guides professional conduct and protects stakeholders

Professional ethics provide frameworks for responsible decision-making, ensuring practitioners act in the best interest of those they serve.

Question 6: Which reversal agent is used to reverse the effects of benzodiazepines administered during procedural sedation?

Neostigmine
Naloxone
Sugammadex
Flumazenil (Correct answer)

Correct answer: Flumazenil

Flumazenil competitively antagonizes benzodiazepine receptors and is used to reverse benzodiazepine-induced sedation.

Question 7: During a closing count, one instrument cannot be accounted for. What is the appropriate next step?

Perform an X-ray of the patient and conduct a thorough search of the sterile field and room (Correct answer)
Add an additional instrument to balance the count and document the addition
Document the discrepancy and notify the charge nurse after the case
Complete the wound closure and notify the surgeon after the patient leaves the room

Correct answer: Perform an X-ray of the patient and conduct a thorough search of the sterile field and room

An unresolved count discrepancy requires an immediate X-ray and a thorough search of the sterile field and room before the wound is closed.

Question 8: According to AORN, what is the recommended preoperative skin antiseptic of choice for most surgical sites when no contraindication exists?

Plain soap and water preoperative shower only
Iodophor-alcohol combination scrub
10% povidone-iodine paint only
Chlorhexidine gluconate with isopropyl alcohol (CHG-alcohol) (Correct answer)

Correct answer: Chlorhexidine gluconate with isopropyl alcohol (CHG-alcohol)

CHG-alcohol (chlorhexidine gluconate in isopropyl alcohol) is the preferred preoperative skin antiseptic due to its broad-spectrum efficacy, residual activity, and superiority in SSI reduction trials.

Question 9: Which action should the perioperative nurse take when inspecting reusable electrosurgical instruments before a case?

Soak instruments in high-level disinfectant for 20 minutes regardless of prior sterilization
Verify instrument function only by reviewing the sterilization log
Inspect insulation for cracks, pinholes, or discoloration and discard instruments with any defects (Correct answer)
Test each instrument by activating the ESU at full power and touching the tip to a metal basin

Correct answer: Inspect insulation for cracks, pinholes, or discoloration and discard instruments with any defects

Visual and tactile inspection of reusable electrode insulation for any defects is essential, as even small insulation breaches can cause capacitive coupling or direct current leakage during the procedure.

Question 10: Which of the following patients requires placement in a negative-pressure isolation room for perioperative care?

A patient with active pulmonary tuberculosis (Correct answer)
A patient with MRSA wound infection
A patient with Clostridioides difficile colitis
A patient with vancomycin-resistant Enterococcus (VRE)

Correct answer: A patient with active pulmonary tuberculosis

Active pulmonary TB requires airborne precautions, including a negative-pressure room, because Mycobacterium tuberculosis is transmitted via airborne droplet nuclei that remain suspended in air.

Question 11: What is the ALARA principle in radiation safety?

Always Lock And Restrict Access
Automated Limiting Adjustment for Radiation Applications
As Low As Reasonably Achievable — minimize radiation exposure (Correct answer)
All Labs And Rooms Assessed

Correct answer: As Low As Reasonably Achievable — minimize radiation exposure

ALARA means keeping radiation doses as low as reasonably achievable while still obtaining diagnostic-quality images, balancing benefit against risk.

Question 12: Which zone around a sterile-draped table is considered the sterile field boundary per AORN guidelines?

A 12-inch perimeter extending beyond the drape edges
The drape top and sides down to table height
The top surface of the drape only (Correct answer)
The entire surgical suite floor

Correct answer: The top surface of the drape only

Only the top surface of the sterile drape is considered sterile; the edges and sides hanging below table level are not sterile.

Question 13: Which monitoring parameter is considered the gold standard for confirming correct endotracheal tube placement?

Pulse oximetry
Chest auscultation
End-tidal CO2 (ETCO2) capnography (Correct answer)
Chest rise visualization

Correct answer: End-tidal CO2 (ETCO2) capnography

Continuous ETCO2 waveform capnography is the gold standard for confirming and monitoring endotracheal tube placement throughout the procedure.

Question 14: How does documentation support quality in Wound Management?

It only serves administrative purposes
It creates records, ensures consistency, and enables improvement (Correct answer)
Documentation is unnecessary overhead
It is only for billing

Correct answer: It creates records, ensures consistency, and enables improvement

Proper documentation creates accountability, ensures consistency, supports quality improvement, and provides legal protection.

Question 15: A sterile package is found with a small puncture in the outer wrap. The correct action is to:

Apply a sterile patch over the puncture and document
Inspect inner contents visually and use if clean
Reprocess the item regardless of inner wrap integrity (Correct answer)
Use the item if the inner wrap is intact

Correct answer: Reprocess the item regardless of inner wrap integrity

Any breach of sterile packaging — including a puncture in an outer wrap — compromises sterility and requires reprocessing before patient use.

Question 16: A patient develops a fever of 38.5°C on postoperative day 3 after laparoscopic appendectomy. Which SSI classification would apply if wound erythema and purulent drainage are found at the port site?

Healthcare-associated pneumonia
Organ/space SSI
Superficial incisional SSI (Correct answer)
Deep incisional SSI

Correct answer: Superficial incisional SSI

Superficial incisional SSI involves only skin and subcutaneous tissue at the incision site, presenting within 30 days with signs like purulent drainage, erythema, or swelling.

Question 17: Which factor most directly increases a surgical patient's risk for pressure injury during an extended procedure?

Use of general anesthesia
Use of absorbable sutures
Patient age under 30
Prolonged immobility combined with reduced tissue perfusion on bony prominences (Correct answer)

Correct answer: Prolonged immobility combined with reduced tissue perfusion on bony prominences

Immobility during surgery combined with compromised perfusion concentrates pressure on bony prominences, leading to tissue ischemia and pressure injury.

Question 18: What is the primary function of a self-retaining retractor during surgery?

To cut and retract tissue simultaneously
To provide the surgeon with additional grip on slippery tissue
To measure tissue thickness during retraction
To maintain tissue exposure without requiring continuous manual holding (Correct answer)

Correct answer: To maintain tissue exposure without requiring continuous manual holding

Self-retaining retractors maintain tissue exposure on their own, freeing the surgical team's hands for other tasks.

Question 19: What is the purpose of the Aldrete Scoring System used in the PACU?

Measuring surgical wound healing
Assessing intraoperative blood loss
Evaluating patient readiness for discharge from Phase I recovery (Correct answer)
Documenting anesthesia drug dosages

Correct answer: Evaluating patient readiness for discharge from Phase I recovery

The Aldrete Score assesses activity, respiration, circulation, consciousness, and oxygen saturation to determine readiness for Phase I PACU discharge.

Question 20: Which nerve is most at risk during prolonged lithotomy position due to compression at the fibular head?

Femoral nerve
Sciatic nerve
Obturator nerve
Common peroneal nerve (Correct answer)

Correct answer: Common peroneal nerve

The common peroneal nerve wraps around the fibular head and is highly susceptible to compression injury in lithotomy position.

Question 21: During a procedure, the anesthesia provider calls out 'can't intubate, can't oxygenate.' What is the perioperative nurse's immediate priority?

Activate the difficult airway/emergency response and retrieve the emergency cart (Correct answer)
Continue counting instruments
Document the event in the chart
Leave the room to get more help

Correct answer: Activate the difficult airway/emergency response and retrieve the emergency cart

A 'can't intubate, can't oxygenate' scenario is life-threatening; the nurse must immediately activate the emergency response and bring emergency equipment.

Question 22: When caring for a patient undergoing laparoscopic surgery, which risk is unique to the pneumoperitoneum?

Surgical site infection
CO2 gas embolism (Correct answer)
Pressure ulcer formation
Latex allergy reaction

Correct answer: CO2 gas embolism

CO2 used to create pneumoperitoneum can enter the bloodstream through injured vessels, causing potentially fatal gas embolism.

Question 23: Which ethical principle is upheld when a perioperative nurse obtains informed consent verification before a procedure begins?

Fidelity
Justice
Autonomy (Correct answer)
Beneficence

Correct answer: Autonomy

Autonomy respects the patient's right to make informed decisions about their own care, which informed consent verification supports.

Question 24: What is the perioperative nurse's responsibility regarding medication allergies before a case?

Allergies are the sole responsibility of the anesthesia provider
Review allergies only for high-alert medications
Verify and document the patient's allergy history and communicate known allergies to the entire team during the time-out (Correct answer)
Check allergies only if the patient reports a reaction during surgery

Correct answer: Verify and document the patient's allergy history and communicate known allergies to the entire team during the time-out

The perioperative nurse must verify, document, and communicate all known allergies during the pre-procedure verification and time-out so every team member is aware.

Question 25: Which of the following is considered a break in sterile technique?

Wearing a surgical mask in the operating room
Touching a sterile drape with sterile gloves
Keeping sterile instruments on a sterile field
Allowing a sterile object to fall below waist level (Correct answer)

Correct answer: Allowing a sterile object to fall below waist level

In sterile technique, any object that falls below waist level or out of the line of sight is considered contaminated because these areas cannot be consistently monitored for sterility. This principle helps maintain a strict sterile field, preventing microorganisms from non-sterile environments from reaching the surgical site and causing infection.

Question 26: Which documentation element is most critical immediately after an intraoperative adverse event or near-miss?

A note that the event was discussed at the next staff meeting
An objective, factual account of events in the medical record and a facility incident report (Correct answer)
The surgeon's verbal statement about the event
Documentation that the patient was informed during recovery

Correct answer: An objective, factual account of events in the medical record and a facility incident report

Timely, factual documentation in the medical record and a separate incident report are both required for legal, quality, and safety improvement purposes.

Question 27: What is the nurse's priority responsibility during the intraoperative phase?

Ensuring the surgeon’s instruments are sterile
Monitoring the patient's vital signs and condition (Correct answer)
Managing the surgeon's preferences for positioning
Arranging postoperative follow-up appointments

Correct answer: Monitoring the patient's vital signs and condition

During the intraoperative phase, the patient is under anesthesia and highly vulnerable. The nurse's priority responsibility is continuous monitoring of vital signs, oxygen saturation, cardiac rhythm, and overall physiological condition. This constant vigilance allows for the immediate detection of any adverse reactions or changes, ensuring prompt intervention to maintain patient stability and safety throughout the surgery.

Question 28: An OR team is setting up for a procedure involving a patient with active pulmonary tuberculosis. Which respiratory precaution is required for perioperative personnel?

Positive-pressure isolation room and PAPR for everyone
N95 or higher respirator fit-tested to each individual (Correct answer)
PAPR for the surgeon only, surgical masks for others
Standard surgical mask for all personnel

Correct answer: N95 or higher respirator fit-tested to each individual

Airborne precautions for TB require a minimum of an N95 respirator that has been fit-tested to each individual user.

Question 29: Which assessment finding in a post-operative patient who was in lithotomy position most suggests compartment syndrome of the lower leg?

Mild ankle swelling
Pain out of proportion to the procedure and firmness of the calf (Correct answer)
Numbness in the great toe only
Redness over the tibial crest

Correct answer: Pain out of proportion to the procedure and firmness of the calf

Disproportionate pain combined with tense compartment firmness are hallmark early signs of compartment syndrome requiring immediate evaluation.

Question 30: Which is the correct technique for the scrub person to transfer a sharp instrument to the surgeon while maintaining safety?

Toss it across the sterile field
Hold the sharp end while the surgeon grasps the handle
Hand it handle-first while making eye contact
Use the neutral zone (hands-free technique) by placing the instrument in a designated basin (Correct answer)

Correct answer: Use the neutral zone (hands-free technique) by placing the instrument in a designated basin

The neutral zone (hands-free technique) eliminates simultaneous handling of sharps between two people, preventing percutaneous injury.

Question 31: Which type of OR attire is specifically required in the semi-restricted area of the surgical suite?

Street clothes with a gown cover-up
Full sterile gown and gloves with hood
Surgical scrub attire and hair covering (Correct answer)
Sterile draping over street clothes is acceptable

Correct answer: Surgical scrub attire and hair covering

The semi-restricted area requires clean surgical scrub attire and a hair covering to reduce the risk of shedding microorganisms from hair and skin.

Question 32: Which packaging material is compatible with steam but NOT recommended for hydrogen peroxide plasma sterilization?

Nonwoven polypropylene wrap
Tyvek pouches
Rigid sterilization containers with plasma-compatible filters
Cellulose-based materials (paper/muslin) (Correct answer)

Correct answer: Cellulose-based materials (paper/muslin)

Cellulose-based materials absorb hydrogen peroxide, disrupting the plasma cycle and are therefore incompatible with H2O2 plasma sterilization.

Question 33: Which assessment finding in the preoperative holding area requires the nurse to notify the surgeon before proceeding?

Patient had clear liquids 4 hours ago
Patient reports taking aspirin daily and took it this morning (Correct answer)
Mild anxiety about the procedure
Blood pressure of 128/82 mmHg

Correct answer: Patient reports taking aspirin daily and took it this morning

Aspirin taken the day of surgery increases bleeding risk, and the surgeon must decide whether to delay or proceed with appropriate precautions.

Question 34: What is the primary purpose of cleaning instruments BEFORE sterilization?

To reduce packaging time by removing debris
To eliminate bioburden that can shield microorganisms from the sterilant (Correct answer)
To remove surface rust and improve instrument longevity
To meet Joint Commission aesthetic standards

Correct answer: To eliminate bioburden that can shield microorganisms from the sterilant

Organic soil and debris create a physical barrier that prevents the sterilant from contacting microorganisms, making cleaning the most critical pre-sterilization step.

Question 35: Which inhalation anesthetic agent is known for its pungent odor and is most irritating to the airway, making it unsuitable for inhalation induction?

Desflurane (Correct answer)
Sevoflurane
Isoflurane
Nitrous oxide

Correct answer: Desflurane

Desflurane has a pungent, airway-irritating odor that causes coughing and laryngospasm, making it unsuitable for mask induction.

Question 36: What is the recommended minimum free air space around packages in a steam sterilizer load?

Items may be stacked tightly if chamber pressure is increased
Items should be loosely arranged with space between packs (Correct answer)
No spacing required if items are wrapped
Packs must be separated by exactly 1 inch on all sides

Correct answer: Items should be loosely arranged with space between packs

AORN guidelines require loose arrangement with space between packs to allow adequate steam penetration and air removal.

Question 37: A patient undergoing abdominal surgery develops a wound dehiscence on postoperative day 5. Which type of wound closure will MOST likely be used to manage this complication?

Vacuum-assisted closure only
Primary intention
Tertiary (delayed primary) intention (Correct answer)
Secondary intention

Correct answer: Tertiary (delayed primary) intention

Tertiary (delayed primary) closure allows the wound to be left open temporarily for observation and debridement before surgical closure, optimizing conditions for healing.

Question 38: The AORN recommended minimum team size for safely turning an average adult patient prone from supine is:

At least three to four people with an identified leader (Correct answer)
Two people
Five people minimum regardless of patient size
One nurse and the surgeon

Correct answer: At least three to four people with an identified leader

AORN recommends at least three to four team members with a designated leader to safely coordinate airway protection, trunk, and extremity control during prone turning.

Question 39: Which factor most significantly contributes to surgical site infections (SSIs)?

Type of anesthesia used
Duration of the surgery (Correct answer)
The patient’s age
Patient’s fasting period

Correct answer: Duration of the surgery

The duration of surgery is a significant risk factor for surgical site infections (SSIs) because prolonged exposure of tissues to the environment and increased manipulation can lead to greater bacterial contamination. Longer procedures also correlate with increased patient stress and potential for compromised immune response, further elevating infection risk.

Question 40: Which AORN-recommended practice addresses smoke plume generated during laser or electrosurgical procedures?

Using a smoke evacuator at the source of plume generation (Correct answer)
Wearing standard surgical masks only
Limiting smoke exposure to 10 minutes per procedure
Opening OR doors to ventilate

Correct answer: Using a smoke evacuator at the source of plume generation

AORN requires smoke evacuators be placed within 2 cm of the plume source to capture carcinogenic and infectious aerosols before dispersal.

Question 41: An epidural catheter is most commonly placed at which spinal level for cesarean section anesthesia?

S1–S2
C7–T1
T4–T6
L3–L4 or L4–L5 (Correct answer)

Correct answer: L3–L4 or L4–L5

For labor and cesarean section, epidural catheters are placed in the lumbar region (L3-L4 or L4-L5) to avoid spinal cord injury and to target the desired dermatomes.

Question 42: During a procedure, the sterile field is inadvertently left unattended for 15 minutes. What should happen?

The field is considered potentially compromised and must be re-established (Correct answer)
Cover the field with a sterile towel and resume after confirming no contamination
Document the event and continue if the patient's safety allows
Resume the procedure if no one entered the room during that time

Correct answer: The field is considered potentially compromised and must be re-established

An unmonitored sterile field is considered potentially contaminated and must be re-established to ensure patient safety.

Question 43: When performing terminal cleaning of an OR after a case involving an infectious patient, which sequence is correct?

Overhead equipment and lights first, then horizontal surfaces, then floors last (Correct answer)
Walls first, then lights, then floors and equipment simultaneously
All surfaces simultaneously with different team members using the same product
Floors first, then horizontal surfaces, then lights and overhead equipment

Correct answer: Overhead equipment and lights first, then horizontal surfaces, then floors last

Terminal cleaning follows a top-down approach — starting with overhead equipment and lights to prevent re-contaminating already-cleaned lower surfaces as debris falls.

Question 44: For a robotic-assisted laparoscopic procedure requiring steep Trendelenburg, the scrub person's PRIMARY positioning concern beyond nerve protection is:

Risk of patient sliding cephalad off the table
Risk of patient sliding caudally toward the foot of the table (Correct answer)
Increased risk of hypothermia
Increased risk of retinal detachment

Correct answer: Risk of patient sliding caudally toward the foot of the table

In steep Trendelenburg, gravity pulls the patient headward; anti-slide measures at the shoulders and chest are essential to prevent caudal drift.

Question 45: Which instrument should be used to hold tissue without crushing it during delicate surgery?

DeBakey tissue forceps (Correct answer)
Allis forceps
Kocher clamp
Ochsner clamp

Correct answer: DeBakey tissue forceps

DeBakey tissue forceps have fine, atraumatic serrations that hold tissue gently without crushing, making them ideal for delicate tissue handling.

Question 46: When using a shoulder brace in the Trendelenburg position to prevent caudal patient sliding, placement should be at the:

Acromial process padded to avoid direct contact with the brachial plexus (Correct answer)
Acromioclavicular joint
Acromion tip only
Mid-clavicle

Correct answer: Acromial process padded to avoid direct contact with the brachial plexus

Shoulder braces must be padded and positioned at the acromial process; misplacement over the clavicle or plexus risks brachial plexus compression injury.

Question 47: What is the correct order for donning PPE?

Mask, gloves, gown, eye protection
Gloves, gown, mask, eye protection
Any order is acceptable
Gown, mask, eye protection, gloves (Correct answer)

Correct answer: Gown, mask, eye protection, gloves

The correct donning sequence is gown first, then mask/respirator, eye protection/face shield, and gloves last. This prevents contamination during application.

Question 48: According to AORN guidelines, where should the electrosurgical pencil (active electrode) be stored when not in active use during surgery?

Handed off the sterile field to the circulator when not needed
On the sterile field drape near the incision site for quick access
Submerged in sterile saline to prevent accidental activation
In a clean, dry holster or holder away from the patient and drapes (Correct answer)

Correct answer: In a clean, dry holster or holder away from the patient and drapes

AORN recommends storing the inactive electrosurgical pencil in a clean, dry holster positioned away from the patient to prevent accidental activation, fire, or unintended burns.

Question 49: A patient undergoing a total hip replacement is found to have an active methicillin-resistant Staphylococcus aureus (MRSA) nasal colonization. Which preoperative intervention is recommended by AORN?

Apply mupirocin nasal ointment and chlorhexidine skin bathing protocol preoperatively (Correct answer)
Administer vancomycin prophylaxis only without decolonization
Proceed without modification since colonization is not active infection
Cancel the surgery until MRSA is fully eradicated

Correct answer: Apply mupirocin nasal ointment and chlorhexidine skin bathing protocol preoperatively

AORN recommends a decolonization protocol including intranasal mupirocin and preoperative chlorhexidine bathing for MRSA-positive patients to reduce SSI risk.

Question 50: Which action best prevents retained surgical items (RSIs) during an emergency case when a counting policy cannot be fully followed?

Use only instrument trays without sponges
Perform an intraoperative X-ray before wound closure (Correct answer)
Skip documentation and proceed without any count
Rely on the surgeon's memory

Correct answer: Perform an intraoperative X-ray before wound closure

Intraoperative radiographic imaging before closure is the safest backup measure when a standard count cannot be completed.

Question 51: What is the purpose of maintaining a minimum of 15 air exchanges per hour in an operating room?

To keep temperature within the recommended range of 68°F–75°F
To dilute and remove airborne contaminants and reduce surgical site infection risk (Correct answer)
To maintain positive pressure relative to surrounding corridors
To prevent static electricity buildup on equipment surfaces

Correct answer: To dilute and remove airborne contaminants and reduce surgical site infection risk

Fifteen or more total air exchanges per hour (with at least 3 being outside air) dilute microbial load and particulates, directly reducing surgical site infection (SSI) risk.

Question 52: Which document outlines the scope of practice specifically for perioperative nurses?

The Joint Commission Accreditation Manual
AORN's Perioperative Nursing Data Set (PNDS) (Correct answer)
CMS Conditions of Participation
The American Nurses Association Code of Ethics only

Correct answer: AORN's Perioperative Nursing Data Set (PNDS)

The PNDS is AORN's standardized nursing language that defines perioperative nursing practice and patient outcomes.

Question 53: Which of the following is an evidence-based strategy recommended by AORN to prevent venous thromboembolism (VTE) in surgical patients?

Limiting IV fluid administration intraoperatively
Applying sequential compression devices before induction and maintaining throughout the perioperative period (Correct answer)
Administering oral aspirin 30 minutes before surgery
Keeping the patient supine for 12 hours postoperatively

Correct answer: Applying sequential compression devices before induction and maintaining throughout the perioperative period

Sequential compression devices promote venous return and reduce DVT risk and should be applied before induction when the patient is most at risk.

Question 54: Which action is taken when a biological indicator returns a positive result after a routine sterilization cycle?

Notify the surgeon but continue scheduled surgeries
Continue using items if chemical indicators passed
Quarantine all items from that load and recall items already used (Correct answer)
Repeat the cycle and retest before releasing any items

Correct answer: Quarantine all items from that load and recall items already used

A positive BI result requires immediate quarantine of all items from the implicated load and recall of any items already distributed or implanted.

Question 55: What is the primary responsibility of the circulating nurse during a surgical procedure?

Assisting the surgeon with sterile instruments
Monitoring and documenting the patient’s status (Correct answer)
Closing the surgical incision after the procedure
Administering anesthesia to the patient

Correct answer: Monitoring and documenting the patient’s status

The circulating nurse's primary responsibility during a surgical procedure is to manage the overall environment of the operating room and advocate for the patient. This includes monitoring the patient's physiological status, ensuring patient safety, managing non-sterile supplies, and meticulously documenting all aspects of care, while maintaining communication with the sterile team.

Question 56: What is the primary purpose of professional certification in Anesthesia Basics?

To replace practical experience
To meet legal requirements only
To validate competency and knowledge in the field (Correct answer)
To increase salary automatically

Correct answer: To validate competency and knowledge in the field

Certification validates that a professional has met established standards of knowledge and competency in Anesthesia Basics.

Question 57: When documenting blood loss during a procedure, which source should the perioperative nurse use as the primary reference for the estimated amount?

The anesthesia provider's running blood loss total
The surgeon's verbal estimate at wound closure
The scrub technician's visual estimate
Suction canister volume plus surgical sponge weights (Correct answer)

Correct answer: Suction canister volume plus surgical sponge weights

Accurate estimated blood loss (EBL) is calculated by measuring suction canister volumes and weighing surgical sponges to quantify blood absorbed.

Question 58: Which action by the circulating nurse best reduces the risk of surgical site infection (SSI) during a procedure?

Using warm saline for irrigation
Applying a second set of sterile drapes
Administering prophylactic antibiotics before incision as ordered (Correct answer)
Keeping the OR door open for ventilation

Correct answer: Administering prophylactic antibiotics before incision as ordered

Prophylactic antibiotics administered within the recommended window before incision significantly reduce SSI risk.

Question 59: Which anesthetic agent is most commonly associated with malignant hyperthermia when used in susceptible patients?

Ketamine
Succinylcholine (Correct answer)
Propofol
Midazolam

Correct answer: Succinylcholine

Succinylcholine (and volatile inhalation agents) are the primary triggers of malignant hyperthermia in genetically susceptible individuals.

Question 60: According to AORN guidelines, where is the most appropriate site for placing the dispersive electrode?

Over a scar or skin fold for better adhesion
On the patient's chest, regardless of surgical site location
On a well-vascularized, large muscle mass closest to the operative site (Correct answer)
Over a bony prominence closest to the surgical site

Correct answer: On a well-vascularized, large muscle mass closest to the operative site

AORN recommends placing the dispersive electrode on a large, well-vascularized muscle mass as close to the operative site as possible to optimize current return and minimize resistance.

Question 61: Which describes the correct handling of sterile items near the edges of a sterile field?

Only the center 50% of the drape is considered truly sterile
The entire drape surface is sterile if sealed packages were used
Edges are sterile as long as they remain above the table level
A one-inch border around the drape edge is considered non-sterile (Correct answer)

Correct answer: A one-inch border around the drape edge is considered non-sterile

AORN defines a one-inch (approximately 2.5 cm) border at the edges of a sterile drape as non-sterile due to contamination risk from handling and proximity to non-sterile surfaces.

Question 62: Which items are included in the standardized perioperative surgical count per AORN guidelines?

Sponges and sharps only
Sponges, sharps, instruments, and miscellaneous items (Correct answer)
Only items that could be retained in a body cavity
Instruments and sutures only

Correct answer: Sponges, sharps, instruments, and miscellaneous items

AORN's recommended practices include counting sponges, sharps, instruments, and any miscellaneous items (e.g., vessel loops, electrosurgical tips) that could be retained.

Question 63: What is the correct order for donning PPE?

Any order is acceptable
Gloves, gown, mask, eye protection
Mask, gloves, gown, eye protection
Gown, mask, eye protection, gloves (Correct answer)

Correct answer: Gown, mask, eye protection, gloves

The correct donning sequence is gown first, then mask/respirator, eye protection/face shield, and gloves last. This prevents contamination during application.

Question 64: A circulator notices a small tear in a sterile gown cuff during a procedure. What is the correct response?

Notify the scrub and change the gown immediately (Correct answer)
Continue if gloves are intact, since gloves are the primary barrier
Cover the tear with sterile tape and continue
Double-glove over the existing glove to compensate

Correct answer: Notify the scrub and change the gown immediately

A compromised gown must be replaced immediately because it no longer provides an effective sterile barrier.

Question 65: Which study approach is most effective for Wound Management material?

Passive re-reading of notes
Highlighting all text
Active recall with practice questions (Correct answer)
Studying for very long sessions without breaks

Correct answer: Active recall with practice questions

Active recall through practice questions is the most effective study method, as it strengthens memory retrieval pathways.

Question 66: A perioperative nurse notes a discrepancy between the surgeon's verbal order for irrigation solution concentration and the written order. How should this be documented?

Withhold the irrigation until risk management is consulted
Use the written order and make no documentation of the verbal discrepancy
Clarify the order with the surgeon, document the clarification, and proceed with the verified order (Correct answer)
Follow the verbal order and document it without noting the discrepancy

Correct answer: Clarify the order with the surgeon, document the clarification, and proceed with the verified order

Order discrepancies must be clarified at the source, and the clarification and resulting verified order must be documented before the medication is administered.

Question 67: A new policy requires perioperative nurses to use a specific surgical hand antisepsis product. A nurse believes the old product was more effective. The MOST professional response is to:

Continue using the old product and not inform anyone
Refuse to use the new product until personally convinced it is superior
Ask the surgeon to intercede on their behalf
Follow the new policy while submitting evidence-based concerns through the appropriate policy review process (Correct answer)

Correct answer: Follow the new policy while submitting evidence-based concerns through the appropriate policy review process

Professional nurses comply with current policy while using appropriate channels—such as shared governance or policy committees—to raise evidence-based concerns.

Question 68: Which personal protective equipment (PPE) is required when handling a patient with Clostridioides difficile (C. diff) in the perioperative setting?

Gown and gloves with contact precautions (Correct answer)
N95 respirator and face shield
Powered air-purifying respirator (PAPR)
Surgical mask and eye protection only

Correct answer: Gown and gloves with contact precautions

C. difficile requires contact precautions — gown and gloves — because it spreads via the fecal-oral route and spores are not killed by alcohol-based hand rubs.

Question 69: In AORN's team nursing model for the perioperative setting, which statement about role boundaries is MOST accurate?

Each role has defined responsibilities, and crossing those boundaries requires clear delegation by the RN (Correct answer)
All team members may perform nursing assessments interchangeably
Surgical technologists can assume the circulating role when the RN is briefly absent
Role boundaries apply only during teaching cases

Correct answer: Each role has defined responsibilities, and crossing those boundaries requires clear delegation by the RN

AORN's model requires that role crossings occur only through appropriate RN delegation, maintaining accountability and safety.

Question 70: An AORN perioperative nurse serves as the patient advocate during surgery primarily by:

Ensuring the patient's rights and preferences are upheld when they cannot speak for themselves (Correct answer)
Directing the surgical team on operative technique
Documenting the procedure for billing purposes
Managing the sterile instrument count alone

Correct answer: Ensuring the patient's rights and preferences are upheld when they cannot speak for themselves

Patient advocacy is a core perioperative nursing role, especially since patients under anesthesia cannot advocate for themselves.

Question 71: What is the recommended minimum air exchanges per hour in an operating room to reduce airborne contamination?

15 air exchanges per hour
10 air exchanges per hour
20 air exchanges per hour (Correct answer)
5 air exchanges per hour

Keep all pieces together and count them as one item throughout the procedure (Correct answer)
Discard the cut sponge and replace it with a new one from the count
Remove the cut sponge from the count and document removal
Count the pieces separately as individual items

Correct answer: Keep all pieces together and count them as one item throughout the procedure

When a sponge is cut, all pieces must be kept together and counted as a single unit to prevent counting discrepancies.

Question 87: Why must sterile gloves be donned using the closed technique immediately after gowning?

To comply with OSHA bloodborne pathogen requirements
To prevent bare skin contact with the outer glove surface, maintaining sterility (Correct answer)
Because the open technique is reserved for non-surgical sterile procedures
To speed up the process and reduce total time before incision

Correct answer: To prevent bare skin contact with the outer glove surface, maintaining sterility

The closed technique uses the gown cuff to handle the glove, preventing hand skin from contacting the sterile outer glove surface and maintaining its sterility.

Question 88: What is the purpose of a risk assessment?

To track inventory levels
To identify potential hazards and determine mitigation measures (Correct answer)
To assign work shifts
To calculate financial budgets

Correct answer: To identify potential hazards and determine mitigation measures

Question 97: When two scrubbed team members need to pass each other in the OR, which method maintains aseptic technique?

One passes behind the other with back to the sterile field
One steps off the sterile platform while the other passes
They face each other while passing to monitor the sterile field (Correct answer)
They pass back-to-back keeping both away from the sterile field

Correct answer: They face each other while passing to monitor the sterile field

Scrubbed team members should pass each other face-to-face to ensure both can monitor the sterile field and avoid accidental contamination.

Question 98: Which intervention is most effective at preventing surgical site infections (SSIs) related to patient temperature?

Maintaining patient normothermia throughout the perioperative period (Correct answer)
Applying povidone-iodine to the skin immediately post-op
Using laminar airflow only in orthopedic cases
Administering broad-spectrum antibiotics for all cases

Correct answer: Maintaining patient normothermia throughout the perioperative period

Maintaining normothermia reduces SSI risk by preserving immune function and tissue oxygenation, which are impaired by hypothermia.

Question 99: Which of the following best describes a 'retained surgical item' (RSI)?

An item that was counted but not used
An instrument handed back to the circulating nurse
A sharps item returned to the back table
Any item unintentionally left inside a patient after surgery (Correct answer)

Correct answer: Any item unintentionally left inside a patient after surgery

Question 103: A patient with a class IV (dirty-infected) wound is undergoing debridement. The perioperative nurse should anticipate which wound closure method?

Delayed primary closure or healing by secondary intention (Correct answer)
Subcuticular absorbable suture closure
Tissue adhesive (cyanoacrylate) closure
Primary closure with staples

Correct answer: Delayed primary closure or healing by secondary intention

Class IV wounds contain pre-existing infection or devitalized tissue; immediate primary closure is contraindicated due to high SSI risk, so delayed or secondary closure is preferred.

Question 104: What action should be taken if a closing count does not reconcile?

Inform the surgeon immediately and search the field, patient, and environment before closure (Correct answer)
Notify the charge nurse and continue the case
Proceed with closure and document the discrepancy
Recount only the sponges

Correct answer: Inform the surgeon immediately and search the field, patient, and environment before closure

An unresolved count discrepancy requires immediate notification of the surgeon and a systematic search before closure to prevent a retained foreign body.

Question 105: A scrub technician opens a peel-pack and the inner contents touch the non-sterile outer wrapper. What is the correct action?

Inspect the item and use it if no visible contamination is present
Consider the item contaminated and obtain a new sterile item (Correct answer)
Ask the surgeon whether the item is critical enough to use anyway
Wipe the item with a sterile alcohol swab and place it on the field

Correct answer: Consider the item contaminated and obtain a new sterile item

Contact between the sterile item and the non-sterile outer wrapper renders the item contaminated; it must be discarded and replaced.

Question 106: A patient reports a latex allergy during the preoperative assessment. Which scheduling adjustment is most important?

Schedule the case as the first case of the day to minimize airborne latex particle exposure (Correct answer)
Request that the anesthesiologist avoid all IV medications in rubber-stoppered vials
Assign an extra scrub technician to monitor for allergic reactions
Schedule the case last of the day to allow thorough OR cleaning afterward

Correct answer: Schedule the case as the first case of the day to minimize airborne latex particle exposure

Scheduling a latex-sensitive patient as the first case minimizes airborne latex allergen accumulation from previous cases, reducing the risk of anaphylaxis.

Question 107: Which action should be taken with instruments used on a patient with a known prion disease (e.g., CJD)?

Standard steam sterilization followed by quarantine
Segregation and special decontamination protocols per facility policy, or single-use instruments (Correct answer)
Soaking in high-level disinfectant for 30 minutes
Immediate disposal in a biohazard bag after the procedure

Correct answer: Segregation and special decontamination protocols per facility policy, or single-use instruments

Prion-contaminated instruments require specialized handling protocols or single-use instruments because standard sterilization does not inactivate prions.

Question 108: During wound closure, the surgeon asks for a monofilament absorbable suture with a slow absorption rate appropriate for fascia. Which suture material BEST fits this description?

Polyglycolic acid (Dexon)
Plain catgut
Polydioxanone (PDS) (Correct answer)
Polyglactin 910 (Vicryl)

Correct answer: Polydioxanone (PDS)

Polydioxanone (PDS) is a monofilament absorbable suture that retains tensile strength for approximately 6 weeks and is completely absorbed by 6 months, making it ideal for fascial closure.

Question 109: What is the recommended practice when a perioperative nurse relieves another nurse mid-procedure regarding the surgical count?

Wait until a natural count point to perform a handoff count
Accept the outgoing nurse's verbal report of the count status
Review the written count record and sign off without a recount
Perform a count together during the transition to verify all items before accepting responsibility (Correct answer)

Correct answer: Perform a count together during the transition to verify all items before accepting responsibility

AORN recommends that the incoming and outgoing nurses perform a count together during relief to ensure accurate transfer of count accountability.

Question 110: What action should be taken with an instrument that has a cracked or compromised silicone tip protector before sterilization?

Discard the instrument, as the protector damage renders it unsafe
Sterilize the instrument without the protector
Tape the protector in place before placing it in the sterilizer
Replace the damaged tip protector with an intact one before sterilization (Correct answer)

Correct answer: Replace the damaged tip protector with an intact one before sterilization

A cracked tip protector must be replaced because damaged protectors do not protect the instrument tip and may trap moisture that inhibits sterilization.

Question 111: Under AORN's recommended practices, which action best protects the perioperative patient from a retained surgical sponge?

Documenting verbally that no sponges were used
Using radiopaque-marked sponges and performing standardized counts at defined intervals (Correct answer)
Counting only at the close of the procedure to save time
Relying on the surgeon to keep track of sponges used during the case

Correct answer: Using radiopaque-marked sponges and performing standardized counts at defined intervals

Using radiopaque-marked sponges combined with standardized counts at opening, before closure, and at skin closure provides the most reliable protection against retained sponges.

Question 112: A perioperative nurse preceptor's PRIMARY responsibility when orienting a new graduate nurse is to:

Delegate all teaching to the charge nurse
Limit the orientee's exposure to complex cases to reduce errors
Ensure the orientee completes cases as quickly as experienced staff
Facilitate learning while maintaining patient safety throughout the orientation period (Correct answer)

Correct answer: Facilitate learning while maintaining patient safety throughout the orientation period

The preceptor must balance fostering the new nurse's development while never compromising patient safety during any phase of orientation.

Correct answer: Association of periOperative Registered Nurses (AORN)

AORN is the specialty professional organization that develops and maintains evidence-based standards and guidelines specifically for perioperative nursing practice.

Question 114: What is the primary reason OR doors should remain closed during a surgical procedure?

To comply with fire code regulations during procedures
To maintain positive pressure differential and prevent contamination from corridor air (Correct answer)
To keep the room temperature stable for patient comfort
To prevent noise from disturbing the surgical team

Correct answer: To maintain positive pressure differential and prevent contamination from corridor air

OR positive pressure keeps unfiltered corridor air from entering; opening doors disrupts airflow patterns, allows unfiltered air ingress, and increases particle counts at the surgical site.

Question 115: Which action is required when a surgical count is correct and reconciled?

The circulating nurse verbally communicates the correct count to the surgeon and documents it (Correct answer)
The surgeon signs the count sheet
The count sheet is discarded after the case
No action is needed beyond completing the count

Correct answer: The circulating nurse verbally communicates the correct count to the surgeon and documents it

Even a correct count must be verbally reported to the surgeon and documented in the intraoperative record as evidence that no items were retained.

Question 116: Why is accurate documentation critical in perioperative nursing?

To provide legal protection for the hospital only
To ensure the surgeon’s preferences are followed in future cases
To create a comprehensive record of the patient’s care (Correct answer)
To facilitate billing and reimbursement for the procedure

Correct answer: To create a comprehensive record of the patient’s care

Accurate documentation in perioperative nursing is critical because it creates a comprehensive, legal, and chronological record of the patient's entire surgical experience. This detailed record supports continuity of care, facilitates communication among healthcare providers, aids in quality improvement, and serves as a vital reference for future treatment and legal purposes.

Question 117: A perioperative nurse discovers that a surgeon has altered a patient's operative report inaccurately after a complication. The nurse's professional obligation is to:

Accept the surgeon's explanation since they lead the surgical team
Report the falsification to the appropriate authority, such as a compliance officer or risk management (Correct answer)
Correct the report themselves to reflect accurate information
Discuss it only with nursing peers

Correct answer: Report the falsification to the appropriate authority, such as a compliance officer or risk management

Falsification of medical records is a serious legal and ethical violation that must be reported through proper institutional channels such as compliance or risk management.

Question 118: What is the primary goal of maintaining a moist wound environment during healing?

Preventing bacterial colonization entirely
Eliminating the need for wound dressings
Increasing wound surface temperature
Facilitating cell migration and reducing scar formation (Correct answer)

Correct answer: Facilitating cell migration and reducing scar formation

A moist wound environment optimizes cell migration, supports autolytic debridement, and has been shown to reduce scar formation compared to dry healing.

Question 119: The circulator notes that the surgical count is incorrect before skin closure. What is the FIRST action?

Notify the surgeon and perform a methodical recount (Correct answer)
Document the discrepancy and notify the charge nurse after the case
Ask the scrub person to recount alone
Close the incision and obtain an X-ray

Correct answer: Notify the surgeon and perform a methodical recount

An incorrect count requires immediate notification of the surgeon and a systematic recount before closure to locate the missing item.

Question 120: Which electrosurgical waveform mode delivers a continuous, unmodulated current primarily used for cutting tissue?

Naloxone 0.04–0.4 mg IV titrated to effect (Correct answer)
Physostigmine 1 mg IV
Neostigmine 2.5 mg IV with glycopyrrolate
Flumazenil 0.2 mg IV

Correct answer: Naloxone 0.04–0.4 mg IV titrated to effect

Naloxone, an opioid antagonist, is titrated in small doses IV to reverse respiratory depression while minimizing abrupt reversal of analgesia.

Question 122: What is the recommended timing for surgical antibiotic prophylaxis administration?

At the end of the procedure
24 hours before surgery
Within 60 minutes before the surgical incision (120 minutes for vancomycin/fluoroquinolones) (Correct answer)
Immediately after the incision is made

Correct answer: Within 60 minutes before the surgical incision (120 minutes for vancomycin/fluoroquinolones)

Evidence-based guidelines and AORN standards recommend infusing prophylactic antibiotics within 60 minutes of incision (extended to 120 minutes for vancomycin and fluoroquinolones) to ensure adequate tissue levels.

Question 123: Which electrosurgical unit (ESU) practice best prevents a dispersive electrode burns?

Using the lowest possible generator setting regardless of tissue effect
Applying a second dispersive electrode when the first appears loose
Positioning the dispersive electrode on a large, well-vascularized muscle mass close to the operative site (Correct answer)
Placing the dispersive electrode over a bony prominence for firm contact

Correct answer: Positioning the dispersive electrode on a large, well-vascularized muscle mass close to the operative site

The dispersive electrode should be placed over a large muscle mass with good vascularity, close to the surgical site, to ensure low-resistance current distribution and prevent burns.

Question 128: During an emergency situation requiring rapid closure, a count discrepancy is noted. What is the most appropriate action?

Notify the surgeon of the discrepancy, obtain an intraoperative X-ray, and document the events (Correct answer)
Proceed with closure and perform a postoperative X-ray only if symptoms arise
Document the discrepancy and close the wound per surgeon direction
Delay closure until the missing item is physically found

Correct answer: Notify the surgeon of the discrepancy, obtain an intraoperative X-ray, and document the events

Even in emergencies, a discrepancy must be reported to the surgeon, an X-ray obtained when clinically feasible, and all events thoroughly documented.

Question 129: Which of the following is considered a 'high-alert medication' in the perioperative setting?

Povidone-iodine prep solution
Saline irrigation
Sterile water for injection
Heparin (Correct answer)

Correct answer: Heparin

Heparin is classified as a high-alert medication because errors in its administration can cause catastrophic anticoagulation events; it requires independent double-checks.

Question 130: Which intervention is most effective in preventing venous access-related bloodstream infections in surgical patients?

Replacing IV tubing every 24 hours regardless of type
Limiting IV line use to less than 48 hours total
Using maximal sterile barrier precautions during central line insertion (Correct answer)
Applying povidone-iodine to all IV catheter sites daily

Correct answer: Using maximal sterile barrier precautions during central line insertion

Maximal sterile barrier precautions (sterile gown, gloves, cap, mask, and full-body drape) during central venous catheter insertion are the most evidence-based intervention to prevent CLABSI.

Question 131: In the PACU, a patient exhibits stridor, use of accessory muscles, and SpO2 of 88%. What is the most likely cause?

Laryngospasm or upper airway obstruction (Correct answer)
Shivering from hypothermia
Pulmonary embolism
Pain-related tachypnea

Correct answer: Laryngospasm or upper airway obstruction

Stridor with accessory muscle use and low SpO2 indicates laryngospasm or airway obstruction, a life-threatening postoperative emergency.

Question 132: When documenting implant information in the intraoperative record, which data element is required by AORN and The Joint Commission?

The scrub technician who opened the implant
The surgeon's implant preference card number
The implant lot number and manufacturer name (Correct answer)
The cost of the implant

Correct answer: The implant lot number and manufacturer name

Lot number and manufacturer are required for implant traceability so patients can be notified in the event of a recall.

Changing positions with another scrubbed team member face-to-face
Turning their back to the sterile field to retrieve a dropped instrument (Correct answer)
Keeping hands above the level of the sterile drape
Passing instruments within the sterile field with controlled movements

Correct answer: Turning their back to the sterile field to retrieve a dropped instrument

Turning one's back to the sterile field violates aseptic technique because it removes the team member's ability to monitor and protect the sterile area.

Question 134: What is the most effective way to prevent healthcare-associated infections?

Proper hand hygiene (Correct answer)
Taking antibiotics
Cleaning the floor
Wearing gloves at all times

Correct answer: Proper hand hygiene

Hand hygiene (washing with soap and water or using alcohol-based hand rub) is the single most effective measure for preventing the spread of infections in healthcare settings.

Question 135: What distinguishes bipolar electrosurgery from monopolar electrosurgery?

Bipolar electrosurgery uses a separate dispersive electrode on each limb
Bipolar uses higher voltage to achieve faster tissue cutting
Bipolar mode generates a continuous waveform while monopolar uses interrupted pulses
In bipolar electrosurgery, current travels only between the two tips of the instrument, eliminating need for a dispersive electrode (Correct answer)

Correct answer: In bipolar electrosurgery, current travels only between the two tips of the instrument, eliminating need for a dispersive electrode

In bipolar electrosurgery, current passes only between the two tips of the forceps, confining the electrical effect to a very small area and eliminating the need for a dispersive electrode.

Question 136: What does a bispectral index (BIS) monitor measure intraoperatively?

Neuromuscular blockade level
Depth of anesthesia and level of consciousness (Correct answer)
Arterial blood pressure continuously
Cerebral perfusion pressure

Correct answer: Depth of anesthesia and level of consciousness

The BIS monitor analyzes the EEG to produce a 0–100 score reflecting depth of sedation/anesthesia, helping prevent awareness under anesthesia.

Question 137: Which patient factor is an independent risk predictor for peripheral nerve injury during surgery according to AORN evidence-based practice?

Male sex
ASA class I status
Body mass index under 20
Pre-existing peripheral neuropathy or diabetes (Correct answer)

Remove only the outer glove if double-gloving was used and continue
Apply sterile tape over the puncture and continue the procedure

Correct answer: Immediately perform a glove change using assisted technique while maintaining sterile field

A punctured glove must be changed immediately using assisted technique (circulator opens new glove pack) to restore sterile barrier integrity and protect both patient and staff.

Question 181: A surgical instrument with a lumened channel requires what minimum processing classification according to Spaulding?

Critical (Correct answer)
Intermediate
Non-critical
Semi-critical

Correct answer: Critical

Lumened instruments that contact sterile tissue or the vascular system are classified as critical items requiring sterilization.

Question 182: In the context of biofilm formation on surgical instruments, which statement is most accurate?

Biofilms protect microorganisms from disinfection and can cause device-related infections (Correct answer)
Biofilms are easily removed by standard high-level disinfection alone
Once a biofilm forms, the instrument must be discarded
Biofilms form only on implantable devices, not reusable instruments

Correct answer: Biofilms protect microorganisms from disinfection and can cause device-related infections

Biofilms create a protective matrix that dramatically increases microbial resistance to disinfectants and antibiotics, making thorough mechanical cleaning before disinfection/sterilization critical.

Question 183: During a long procedure in the supine position, which area is MOST prone to pressure injury development?

Posterior knees
Anterior thighs
Sacrum and occiput (Correct answer)
Scapulae

Correct answer: Sacrum and occiput

Question 185: Which AORN-recommended practice helps prevent SSI related to hair removal at the surgical site?

Shaving with a razor the night before surgery
Applying depilatory cream 24 hours before surgery
No hair removal is ever required before surgery
Clipping hair with an electric clipper immediately before surgery (Correct answer)

Correct answer: Clipping hair with an electric clipper immediately before surgery

AORN and evidence-based guidelines recommend clipping hair (not shaving) immediately before the procedure to minimize skin microabrasions that increase SSI risk.

Question 186: According to AORN, which is an essential element of a culture of safety in the perioperative environment?

Zero tolerance for any clinical error, with immediate disciplinary action
Limiting communication about errors to senior leadership only
Encouraging staff to report near-misses without fear of punishment (Correct answer)
Assigning blame to the individual who made the error

Correct answer: Encouraging staff to report near-misses without fear of punishment

A just culture of safety requires psychological safety for reporting near-misses so that systemic issues can be identified and corrected.

Question 187: How does documentation support quality in Anesthesia Basics?

It is only for billing
Documentation is unnecessary overhead
It creates records, ensures consistency, and enables improvement (Correct answer)
It only serves administrative purposes

Correct answer: It creates records, ensures consistency, and enables improvement

Proper documentation creates accountability, ensures consistency, supports quality improvement, and provides legal protection.

Question 188: What is the perioperative nurse's documentation obligation when an unlabeled container of medication is found on the sterile field?

Leave it on the field and ask the scrub technician to identify it later
Remove the container from the sterile field, document the event, and notify the surgeon and charge nurse (Correct answer)
Document it only in the anesthesia record
Label it based on the most likely drug and continue the procedure

Correct answer: Remove the container from the sterile field, document the event, and notify the surgeon and charge nurse

Unlabeled medications on the sterile field must be removed immediately, and the incident documented with notification to the surgeon and charge nurse per AORN safe medication practice standards.

Question 189: During a sterile dressing change, the nurse accidentally contaminates a sterile glove. What is the correct action?

Remove the contaminated glove and replace it with a new sterile glove (Correct answer)
Continue the dressing change carefully, avoiding the contaminated area
Wipe the contaminated area with a sterile gauze before continuing
Apply a second sterile glove over the contaminated one

Correct answer: Remove the contaminated glove and replace it with a new sterile glove

A contaminated sterile item must be removed and replaced; double-gloving over contamination does not restore sterility and violates aseptic technique.

Question 190: Which action best ensures patient safety during the intraoperative phase?

Conducting all procedures without a surgical timeout
Allowing visitors in the operating room for emotional support
Verifying the patient's identity and surgical site before the procedure (Correct answer)
Delegating patient positioning entirely to anesthesia staff

Correct answer: Verifying the patient's identity and surgical site before the procedure

Verifying the patient's identity and the correct surgical site, often performed during a 'surgical timeout,' is a paramount safety protocol to prevent wrong-patient or wrong-site surgery. This critical step ensures the entire surgical team is aligned on the procedure details immediately before incision. It significantly reduces the risk of severe errors and is a cornerstone of patient safety in the operating room.

Question 191: How should the perioperative nurse document a patient's allergy to latex that was discovered in the preoperative assessment?

Only verbally to the scrub technician
In the postoperative care unit record only
On a sticky note attached to the chart
In the allergy section of the intraoperative record and communicated in the hand-off report (Correct answer)

Correct answer: In the allergy section of the intraoperative record and communicated in the hand-off report

Latex allergy must be prominently recorded in the allergy section of the intraoperative record and verbally communicated during every hand-off to prevent exposure.

Question 192: Which type of surgical drain operates by creating suction through a compressed reservoir attached to drain tubing?

Jackson-Pratt drain (Correct answer)
Penrose drain
Sump drain
T-tube drain

Correct answer: Jackson-Pratt drain

The Jackson-Pratt drain uses a bulb-shaped reservoir that, when compressed, creates negative pressure to actively evacuate fluid from the wound.

Question 193: Why is patient positioning significant during surgery?

To improve the visibility of the surgical site
To provide comfort for the surgical team
To prevent injury to the patient during the procedure (Correct answer)
To reduce the risk of the surgical site becoming contaminated

Correct answer: To prevent injury to the patient during the procedure

Proper patient positioning during surgery is critical to prevent various injuries, including nerve damage, pressure ulcers, musculoskeletal strain, and circulatory compromise. The surgical team carefully positions the patient to ensure optimal access to the surgical site while simultaneously protecting vulnerable body parts and maintaining physiological stability throughout the procedure. This meticulous attention to positioning is a vital aspect of patient safety.

Question 194: What is the rationale for keeping the sterile field at or above waist level?

OSHA regulations require table height to be waist level
Items below waist level are considered contaminated per aseptic principles (Correct answer)
It improves visibility for all team members
It reduces the risk of ergonomic injury to the scrub person

Correct answer: Items below waist level are considered contaminated per aseptic principles

AORN guidelines consider anything below the waist level of a sterile-gowned person to be unsterile, because those areas cannot be consistently monitored.

Question 195: How should all medications and solutions on the sterile back table be labeled?

Verbal communication to the surgeon is sufficient labeling
Labels are applied only when more than one medication is on the field
Labels are only required for high-alert medications
Each container must be labeled with the drug name, concentration, and amount immediately upon transfer to the field (Correct answer)

Correct answer: Each container must be labeled with the drug name, concentration, and amount immediately upon transfer to the field

AORN and The Joint Commission require that every medication and solution on the sterile field be labeled immediately — even if only one medication is present — to prevent mix-ups.

Question 196: Which of the following BEST describes the nurse's documentation role during an intraoperative cardiac arrest?

Designate a recorder to document resuscitation events in real time, then complete the record immediately after (Correct answer)
Have the anesthesiologist document all events
Document only the outcome (survived/expired)
Defer all documentation until after the resuscitation is complete

Correct answer: Designate a recorder to document resuscitation events in real time, then complete the record immediately after

AORN recommends designating a recorder during resuscitation to capture interventions in real time, with the record completed in full immediately after stabilization.

Question 197: When a perioperative nurse participates in a root cause analysis (RCA) following a sentinel event, their role includes:

Protecting colleagues from disciplinary action
Providing honest, objective information to identify system failures and prevent recurrence (Correct answer)
Representing the hospital's legal interests
Determining who is legally liable for the event

Correct answer: Providing honest, objective information to identify system failures and prevent recurrence

In an RCA, the nurse's role is to contribute honest, factual input to identify system-level contributors to the event and prevent future occurrences.

Question 198: A scrub person inadvertently contaminates a glove during a procedure. What is the correct action?

Notify the circulator and perform a glove change using the closed technique (Correct answer)
Apply sterile drape over the contaminated glove
Continue the case and change gloves at the end
Spray the glove with antiseptic and continue

Correct answer: Notify the circulator and perform a glove change using the closed technique

Any break in sterile technique requires immediate correction; the scrub person must change the contaminated glove using a closed-glove technique.

Question 199: What does the term 'look-alike, sound-alike' (LASA) refer to in medication safety?

Drugs with similar names or packaging that are frequently confused with one another (Correct answer)
Medications that have the same mechanism of action
Medications stored in identical containers for convenience
Generic drugs that look like brand-name drugs

Correct answer: Drugs with similar names or packaging that are frequently confused with one another

LASA medications share visual or phonetic similarities that make them prone to mix-ups; AORN recommends separating LASA drugs physically and using tall-man lettering to distinguish them.

Question 200: At which points during a procedure must counts be performed per AORN standards?

Only when a discrepancy is suspected
Only at skin closure
Before the procedure, at closure of each cavity, at skin closure, and when the team changes (Correct answer)
Only before the procedure and at skin closure

Correct answer: Before the procedure, at closure of each cavity, at skin closure, and when the team changes

AORN mandates counts at specific intervals — initial, before closure of each body cavity, at skin closure, and upon significant team member changes.

Question 201: A patient with an implanted cardiac pacemaker requires monopolar electrosurgery. Which intervention should the perioperative nurse prioritize?

Remove the pacemaker before surgery begins
Use the highest available power setting to minimize procedure time
Switch the ESU to coagulation-only mode for the entire case
Place the dispersive electrode as far from the pacemaker as possible and use short, intermittent bursts (Correct answer)

Correct answer: Place the dispersive electrode as far from the pacemaker as possible and use short, intermittent bursts

Placing the dispersive electrode to route current away from the pacemaker and using short, intermittent bursts minimizes electromagnetic interference that could reprogram or inhibit the device.

Question 202: During a prolonged lithotomy procedure, a patient's legs should be lowered slowly and simultaneously at the end of the case primarily to prevent:

Foot drop
Sudden hypotension from redistribution of blood volume to lower extremities (Correct answer)
Urinary retention
Hip dislocation

Correct answer: Sudden hypotension from redistribution of blood volume to lower extremities
