What is Perioperative Nursing?

Perioperative nursing is the specialty that spans care before, during, and after surgery. Perioperative nurses ensure patient safety, sterile technique, accurate documentation, and smooth team communication across the surgical pathway. They manage complex environments (OR, PACU, preop), respond to crises (malignant hyperthermia, anaphylaxis, massive hemorrhage), and coordinate everything from airway and analgesia plans to implant traceability and infection surveillance.

Sample Questions and Answers

A perioperative nurse is performing the “time-out” immediately before incision. Which of the following is the most important element to confirm during the time-out?

A. Sterile instrument packaging integrity
B. Patient identity, correct site and procedure
C. Estimated blood loss from previous case
D. Availability of postoperative transport
Correct: B
Explanation: The time-out’s core purpose is to prevent wrong-patient/wrong-site/wrong-procedure errors by verbally confirming patient identity, correct surgical site and planned procedure with the entire team present. This single verification step has the greatest immediate impact on preventing catastrophic errors and improves teamwork and shared situational awareness.

According to current ASA guidance, which is acceptable for healthy adults before elective general anesthesia?

A. Solid meal up to 2 hours before induction
B. Clear liquids up to 2 hours before induction
C. No fluids for 12 hours before induction
D. Carbonated beverages up to 1 hour before induction
Correct: B
Explanation: Modern ASA practice guidance allows clear liquids up to two hours before anesthesia in healthy patients to reduce discomfort and hypovolemia while maintaining gastric emptying safety. Solid meals and fatty foods require longer fasting; rigid prolonged fasting is no longer routinely recommended for healthy adults undergoing elective procedures.

Which intervention most reduces surgical site infection (SSI) risk when performed preoperatively?

A. Routine use of topical antibiotics at the incision site by patient before arrival
B. Preoperative bathing with an antiseptic agent per protocol
C. Prolonged preoperative hair removal at home
D. Avoiding any showering for 48 hours preop
Correct: B
Explanation: Evidence supports preoperative bathing with an antiseptic (e.g., chlorhexidine) per facility policy to reduce skin bioburden. Routine topical antibiotics applied by patients and home hair removal can increase infection risk. Proper timing of antiseptic bathing and hair removal modalities (clip not shave) are parts of SSI prevention bundles.

What is the single most reliable action the circulating nurse should take when an instrument, sponge, or needle count does not reconcile before wound closure?

A. Close the wound then obtain an x-ray later
B. Notify the surgeon and initiate a systematic search and x-ray before closure
C. Document and proceed as usual; counts are often incorrect
D. Ask the scrub tech to guess which item is missing and proceed
Correct: B
Explanation: A non-reconciled count is a serious safety issue. The circulating nurse must immediately notify the surgeon and the team, initiate a methodical search, and obtain an intraoperative radiograph if the item cannot be found. Leaving items risks retained foreign bodies, grave patient harm, and severe legal consequences.

Enhanced Recovery After Surgery (ERAS) protocols typically include which perioperative nursing practice?

A. Routine prolonged NPO (nothing by mouth) from midnight for all patients
B. Goal-directed fluid therapy and early postoperative feeding/mobilization
C. Complete withholding of multimodal analgesia
D. Avoidance of prophylactic antiemetics
Correct: B
Explanation: ERAS pathways promote evidence-based elements such as goal-directed fluid management, reduced preoperative fasting, carbohydrate loading where appropriate, multimodal analgesia, early ambulation and feeding—aiming to reduce stress response and improve recovery times. Nurses coordinate and monitor ERAS elements.

A patient on a daily GLP-1 agonist (e.g., semaglutide) is scheduled for elective surgery. Current perioperative guidance suggests:

A. Continue as usual—no special considerations
B. Stop the medication on the day of surgery or as recommended by anesthesia team
C. Double the dose the morning of surgery to reduce nausea
D. Replace it with insulin without consulting anesthesia
Correct: B
Explanation: GLP-1 agonists can delay gastric emptying, raising aspiration risk despite fasting. Expert guidance recommends holding doses per anesthesia/surgical team (often skipping the dose on the day of surgery; weekly agents may be withheld earlier). Decisions should be individualized and coordinated with anesthesia and the prescriber.

Which temperature management strategy is most appropriate intraoperatively to reduce hypothermia risk?

A. Passive warming only (blankets) for procedures >30 minutes
B. Active forced-air warming starting preoperatively and continuing intraoperatively as needed
C. Cooling patient to reduce metabolic demand
D. Letting room temperature determine patient temperature management
Correct: B
Explanation: Active warming (e.g., forced-air warming) begun preoperatively and maintained intraoperatively for many cases prevents perioperative hypothermia, reduces surgical site infections, and improves outcomes. Passive warming is often insufficient for longer or higher-risk procedures; standardized temperature protocols are recommended.

During instrument sterilization, the nurse notices a breach in the packaging integrity of a sterilized tray. The appropriate action is:

A. Use the tray—sterility can be assumed despite minor damage
B. Quarantine the tray, notify sterile processing, and replace with an intact sterile set
C. Rewrap and steam sterilize the same tray in the OR immediately
D. Tape the breach and use the tray for non-sterile tasks only
Correct: B
Explanation: Any breach in sterile packaging compromises sterility. The tray must be quarantined and not used; sterile processing should be notified and a verified sterile replacement obtained. Using or attempting to repair compromised sterile items risks surgical contamination and patient harm.

Which statement about surgical attire and when to don it is correct per contemporary perioperative guidance?

A. Scrubs may be worn in unrestricted public areas of the hospital
B. Dedicated perioperative attire should be worn only in restricted OR zones and not worn outside clinical areas
C. Wearing scrubs outside the facility is acceptable if covered by a coat
D. Head coverings are optional and rarely relevant to infection prevention
Correct: B
Explanation: Perioperative guidance emphasizes wearing dedicated OR attire within restricted zones and avoiding wearing it in public areas to minimize contamination. Head coverings and appropriate attire help reduce microbial shedding; institutions may have specific attire and containment policies to reduce infection and maintain sterile field integrity.

Which is the best perioperative nursing action to reduce venous thromboembolism (VTE) risk in surgical patients?

A. Only educate patients about leg exercises postoperatively
B. Implement risk stratification, pharmacologic prophylaxis when indicated, and mechanical prophylaxis as ordered
C. Avoid pharmacologic prophylaxis to reduce bleeding risk in all patients
D. Encourage bed rest for 48 hours after major surgery
Correct: B
Explanation: VTE prevention requires individualized risk assessment and a combination of measures: appropriate pharmacologic prophylaxis (e.g., heparin, LMWH) when not contraindicated, and mechanical methods (intermittent pneumatic compression). Nursing coordinates implementation, patient education, and adherence to protocols.

Which intraoperative positioning consideration is most important to minimize nerve injury?

A. Padding and neutral alignment of vulnerable areas, frequent checks, and documentation
B. Positioning solely for surgeon convenience without padding
C. Using hard arm boards for stability without padding
D. Reliance on surgical drapes to protect pressure points
Correct: A
Explanation: Preventing position-related nerve and pressure injuries requires careful padding, neutral limb alignment, protection of bony prominences, scheduled checks, and clear documentation. Nurses must advocate for patient safety when positioning conflicts with surgical access.

A perioperative nurse receives a specimen from the surgeon. The nurse should:

A. Label specimen only after leaving the OR to avoid contamination
B. Label the specimen immediately at bedside/sterile field with two patient identifiers and document chain of custody
C. Send the specimen unlabelled with the surgical tray
D. Allow circulating staff to decide when to label later
Correct: B
Explanation: Specimen integrity and patient safety depend on immediate, accurate labeling using two patient identifiers, clear labeling of anatomic site, and documentation of handoffs. Delayed or inaccurate labeling risks specimen misidentification, diagnostic errors, and patient harm.

Which practice most reduces the risk of perioperative fire?

A. Ignoring oxygen enrichment in head/neck procedures
B. Managing ignition sources, controlling oxygen concentration, and using wet towels or drapes as barriers when appropriate
C. Using alcohol-based prep and allowing less than recommended drying time near ignition sources
D. Placing oxygen tubing under the drapes without monitoring
Correct: B
Explanation: Perioperative fire prevention requires controlling the fire triangle: ignition sources (e.g., electrosurgery), oxidizers (oxygen, nitrous oxide), and fuel (alcohol prep, drapes). Proper drying time for antiseptics, minimizing oxidizer concentration, and barriers at the surgical site reduce fire risk. Nursing plays a crucial preventive role.

Which postoperative handover element is essential to include when transferring a patient from the OR to PACU?

A. Only surgical site and estimated blood loss
B. Allergies, airway status, anesthesia and analgesia given, fluid balance, drains/tubes, and outstanding concerns for PACU staff
C. Only billing and scheduling details
D. Family’s social history only
Correct: B
Explanation: A comprehensive handover (SBAR or similar) must include patient identifiers, allergies, airway and respiratory status, anesthesia/analgesia administered, fluid and blood loss, lines and drains, positioning issues, and any intraoperative complications. Complete handover ensures continuity, safety, and appropriate postoperative monitoring.

Regarding antibiotic prophylaxis for surgery, the perioperative nurse’s best practice is to:

A. Give antibiotics at least 24 hours before surgery for all cases
B. Ensure appropriate agent is administered within 60 minutes before incision (120 minutes for certain agents) and document timing
C. Administer after incision to target contamination risk
D. Omit documentation since pharmacy handles it
Correct: B
Explanation: Timely administration (generally within 60 minutes before incision; 120 minutes for agents like vancomycin or fluoroquinolones) is critical to achieve adequate tissue concentrations at incision. Nurses verify correct agent, dose, timing, and document prophylaxis; inappropriate timing reduces effectiveness.

What is the recommended action if a circulating nurse suspects malignant hyperthermia (MH) in a patient showing rising end-tidal CO₂ and muscle rigidity?

A. Document and observe for an hour
B. Immediately call for the MH cart/dantrolene, discontinue triggering agents, hyperventilate with 100% oxygen, and notify anesthesia and surgery team
C. Apply warm blankets and continue case as planned
D. Increase inhalational anesthetic concentration to stabilize patient
Correct: B
Explanation: MH is a life-threatening hypermetabolic reaction requiring immediate action: stop volatile anesthetics and succinylcholine, hyperventilate with 100% oxygen, administer dantrolene promptly, cool the patient, and follow MH protocol. Nurses activate emergency response, prepare drugs, and assist resuscitation.

For prevention of urinary tract infections (UTIs) associated with urinary catheters, best perioperative practice includes:

A. Routine catheterization for every surgical patient regardless of need
B. Use of aseptic technique at insertion, limiting catheter duration, and daily evaluation of necessity
C. Leaving indwelling catheters in place for at least 7 days postoperatively in all cases
D. Replacing catheters every 24 hours regardless of indication
Correct: B
Explanation: Catheter-associated UTI prevention focuses on aseptic insertion, appropriate indication, limiting duration, and daily assessment to remove catheters as soon as no longer needed. Routine use and prolonged duration increase infection risk and are discouraged.

Which documentation detail is most important when a sentinel event occurs in the OR?

A. Short, emotion-based note blaming staff
B. Objective, factual documentation of events, times, actions taken, and notifications without speculation or judgment
C. Leaving the chart blank until after the root cause analysis
D. Writing opinions about colleagues’ performance in the chart
Correct: B
Explanation: Documentation after a sentinel or adverse event must be factual, chronological, and non-speculative, recording objective findings, interventions, patient response, and notifications. Opinions, blame, and conjecture should be avoided; detailed accurate records support patient care and later investigations.

Which sterile technique breach requires immediate action even if the sterile field appears intact?

A. Scrubbed team member touches their mask and then the sterile field
B. Scrubbed members talking during the case
C. Leaving a garbage can near the door
D. Folding back a sterile drape without touching it
Correct: A
Explanation: If a scrubbed person touches a potentially non-sterile surface (like their mask) and then the sterile field, contamination risk exists and must be addressed immediately—by changing gloves/gown or re-establishing sterility as per policy. Minor lapses like talking are less direct breaches but still managed.

The CDC NHSN defines SSI surveillance windows. For most procedures, how long should surveillance for superficial and deep incisional SSIs be performed?

A. 7 days after surgery
B. 30 days after surgery (or up to 90 days for certain implants)
C. 1 year for all procedures
D. No surveillance is necessary after discharge
Correct: B
Explanation: Standard SSI surveillance windows are 30 days postoperatively for non-implant procedures and 90 days (or longer per specific procedure definitions) when prosthetic devices are involved. Accurate surveillance and reporting support infection control and quality improvement.

What is the best perioperative nursing action to reduce microbial contamination from OR traffic?

A. Allow unrestricted door opening during turnover for speed
B. Minimize OR door openings, coordinate equipment/staff outside the room, and plan for supplies to limit unnecessary in/out traffic
C. Encourage family members to enter between cases to check on patient
D. Keep HVAC systems off during procedures to conserve energy
Correct: B
Explanation: OR traffic increases airborne particulates and potential contamination. Coordinating supplies, providing checklists, and minimizing unnecessary door openings reduce contamination risk. Nursing leadership in planning and turnover reduces traffic and improves environmental control.

Which action is most appropriate for perioperative pain management aligned with multimodal analgesia principles?

A. Use only high-dose opioids intraoperatively to simplify postoperative care
B. Combine regional anesthesia, non-opioid analgesics, and opioid sparing techniques when appropriate
C. Avoid nonpharmacologic strategies entirely
D. Delay pain assessment until 24 hours after surgery
Correct: B
Explanation: Multimodal analgesia uses combinations of regional blocks, acetaminophen, NSAIDs (when appropriate), and other agents to reduce opioid requirements and improve pain control. Nurses implement and monitor multimodal plans and educate patients on expectations and therapies.

Which cleaning practice best supports sterilization of reusable surgical instruments?

A. Hand-wiping instruments with detergent only in the OR scrub sink
B. Following manufacturer instructions for cleaning, decontamination, and sterilization in SPD with validated processes and documentation
C. Immersing instruments in plain water overnight then autoclaving
D. Reprocessing unvalidated devices using makeshift methods to save time
Correct: B
Explanation: Reusable instrument safety depends on validated cleaning and sterilization per manufacturer IFUs in central sterile processing (SPD). Proper cleaning, inspection, packaging, sterilizer monitoring, and documentation are required to ensure sterility and patient safety.

Which is the correct response if an OR staff member experiences a needlestick from a contaminated sharp?

A. Clean the area and ignore it if the patient seems low risk
B. Stop procedures as needed, provide first aid, report the exposure immediately, document, and initiate occupational health follow-up per facility policy
C. Continue working and report at the end of the day
D. Dispose of the sharp and keep the event confidential to avoid paperwork
Correct: B
Explanation: Percutaneous exposures require immediate action: allow bleeding, wash the area, report to supervisor/occupational health, document the event, and follow post-exposure protocols (testing, prophylaxis if indicated). Prompt reporting reduces transmission risk and ensures proper follow-up.

When transferring a patient from the operating table to a stretcher, the nurse must ensure:

A. The patient is moved quickly without team coordination
B. Team briefing, proper body mechanics, lockable stretcher, secure lines/tubes, and adequate personnel to prevent falls or device dislodgement
C. Only one person is needed for all transfers
D. Tubes and lines can be disconnected to expedite transfer
Correct: B
Explanation: Safe patient transfer depends on a team brief, adequate personnel, secured airway/lines/drains, locked transfer surfaces, and careful coordination. Disconnected tubes and inadequate staffing increase risk for extubation, bleeding, or falls. Nurses lead and coordinate transfers.

For a patient with diabetes undergoing surgery, optimal perioperative glycemic control aims to:

A. Maintain blood glucose in extreme tight range (<80 mg/dL) to be safest
B. Avoid both significant hyperglycemia and hypoglycemia, using institution protocols to maintain moderate targets and individualized plans
C. Stop all hypoglycemic agents without monitoring glucose levels
D. Ignore glucose until 24 hours after surgery
Correct: B
Explanation: Perioperative glycemic management aims to prevent severe hyperglycemia and hypoglycemia; targets are individualized but generally avoid extreme tight control due to hypoglycemia risk. Nursing involves frequent monitoring, insulin adjustments per protocol, and interprofessional communication.

Which action best supports prevention of pressure injuries during prolonged surgery?

A. Positioning the patient on hard OR table without padding for surgical access
B. Use of pressure-reducing padding, repositioning when feasible, and documentation of risk and preventive measures
C. Leaving the same patient position for any length of procedure without reassessment
D. Using adhesive tapes directly over bony prominences to secure position
Correct: B
Explanation: Preventing pressure injuries requires pressure-reducing surfaces/padding, protecting bony prominences, scheduled reassessment, and documentation. Perioperative nurses advocate for prevention strategies, especially during lengthy procedures or in at-risk patients.

Which perioperative practice improves sterile field integrity during instrument passing?

A. Passing instruments haphazardly to save time
B. Clear verbal or visual cues, controlled movements, and using designated neutral zones for sharps to minimize accidental contamination or injury
C. Scrub tech handing instruments over the patient’s abdomen directly without eye contact
D. Passing needles without a neutral zone to speed turnover
Correct: B
Explanation: Safe instrument passing relies on standardized counting and passing techniques, neutral zones for sharps, verbal cues, and controlled handoffs. These methods reduce sharps injuries, contamination, and improve team coordination in the sterile field.

Which infection prevention practice is essential when using alcohol-based surgical skin prep solutions?

A. Using immediately and draping before product fully dries
B. Allowing appropriate drying time per manufacturer instructions and minimizing pooled solutions under drapes to reduce fire risk and promote antiseptic efficacy
C. Ignoring manufacturer directions since alcohol is always effective instantly
D. Using extra warming devices directly over wet prep to speed the case
Correct: B
Explanation: Alcohol-based preps require specified drying times to achieve maximal antiseptic effect and to avoid fire risk with ignition sources. Pooled prep under drapes increases both infection and fire hazards. Nurses ensure correct application and drying before draping/incision.

What is the primary nursing role in implementing the WHO Surgical Safety Checklist?

A. Only observe and never speak during checklist completion
B. Facilitate team participation, initiate and lead the time-out, verify checklist items, and document completion to ensure safety communication
C. Skip the checklist if the surgeon is experienced
D. Delegate checklist entirely to administrative staff
Correct: B
Explanation: Nurses often lead checklist implementation by calling the time-out, ensuring all team members participate, verifying critical items (identity, procedure, counts, antibiotics), and documenting completion. Active facilitation improves communication and reduces complications across diverse surgical settings.
