A perioperative nurse is assembling a portfolio to maintain CNOR certification and seeks peer feedback. To ensure the feedback reflects comprehensive clinical accountability, who should the nurse select as the evaluator?

An experienced RN colleague who frequently collaborates with the nurse during varied cases.

The surgical department manager who reviews the nurse's annual attendance and budget metrics.

A newly hired surgical technologist who frequently works with the nurse during shifts.

The lead anesthesiologist who observes the nurse during complex airway management procedures.

A patient is scheduled for a L4-L5 microdiscectomy. The patient is currently in the preoperative holding area and has received midazolam but remains conversational. The circulating nurse notes the surgical site is not yet marked.

Request the operating surgeon mark the site before OR transport.

Ask the preoperative nurse to mark the general lumbar area.

Mark the surgical site yourself after verifying the consent form.

Wait until the patient is positioned prone to mark it.

During a five-year recertification cycle, a nurse accumulates forty hours of documented student precepting in the surgical suite. How should the nurse apply these hours toward renewal?

Apply twenty-five precepting hours toward the total perioperative contact hours.

Submit all forty precepting hours as general nursing contact hours.

Convert the forty precepting hours into academic semester credit hours.

Exclude precepting hours because they do not qualify for recertification.

A 16-year-old female presents for surgery due to a ruptured ectopic pregnancy. The patient is awake, alert, and legally married. Her husband and parents are currently en route to the hospital. Which action should the perioperative nurse take regarding the surgical consent?

Secure informed consent directly from the minor patient.

Secure informed consent directly from the patient's husband.

Secure informed consent directly from the patient's parents.

Proceed with the surgery relying upon implied consent.

A patient is preparing for a total hip arthroplasty and reports during the preoperative assessment that she lives with her 82-year-old husband in a third-floor apartment with three flights of stairs and no elevator. Which action should the perioperative nurse take to ensure discharge readiness?

Initiate an immediate social work referral for inpatient rehabilitation evaluation.

Provide written discharge instructions regarding safe stair climbing techniques.

Request a physical therapy consultation for home exercise program development.

Advise the patient's husband to rent a hospital bed for the home.

What is the pass rate?

The first-time pass rate is roughly 69%. This means nearly a third of candidates fail on their initial attempt.

How many questions are on the test?

You will face 200 multiple-choice questions. Only 185 of these are scored. The remaining 15 are unscored pretest items used to evaluate future test material.

How much time do I have to finish?

You get 3 hours and 45 minutes to complete all 200 items. This gives you slightly over one minute per question.

What is the hardest part of the test?

Many candidates struggle with the heavy emphasis on Management of Intraoperative Activities: Patient Care and Safety, which makes up 25% of the total score. Infection Prevention and Control of the Environment, Instrumentation, and Supplies is the second largest section at 16%.

Do I need to memorize facts or apply them?

You must apply your knowledge. The test uses scenario-based questions that require you to analyze clinical situations and choose the safest, most effective nursing action.

What other topics are covered?

You will see questions on Pre/Postoperative Patient Assessment and Diagnosis (15%), Communication and Documentation (11%), Emergency Situations (10%), Management of Intraoperative Activities: Personnel, Services, and Materials (9%), Individualized Plan of Care Development and Expected Outcome Identification (8%), and Professional Accountability (6%).

How many questions do I need to get right to pass?

The exact passing score is determined by a scaling formula. For the precise number of correct items required, check the Competency & Credentialing Institute (CCI) official handbook.

Do I need specific experience before taking it?

Yes. You need a current, unrestricted RN license and 2 years plus 2,400 hours of perioperative nursing experience. At least 1,200 of those hours must be in the intraoperative setting within the past 5 years.

Where do I take the test?

You can test in person at a designated testing center. You also have the option to use a remote proctor to test from home.

How much does it cost to register?

Pricing details are not standardized for all candidates. To find the current fee schedule, check the Competency & Credentialing Institute (CCI) official handbook.

How often do I need to renew my credential?

You must recertify every 5 years. You can do this by earning 125 contact hours (at least 75 perioperative), accumulating 300 professional-activity points, or re-testing. From January 1, 2026, per-category point limits were removed.

What happens if I fail my first attempt?

Retake procedures vary. For specific re-examination policies and limits, you must check the Competency & Credentialing Institute (CCI) official handbook.

How should I prepare for this difficulty level?

Focus on clinical application rather than rote memorization. We offer 2217 practice questions designed to mimic the scenario-based format you will see on test day.

Judge the difficulty yourself

These are three CNOR practice questions at exam difficulty. See where you land. The app has 2,200+, timed and scored.

Question 1

Following a revision total hip arthroplasty, the patient requests to keep the femoral stem. What is the most appropriate action for the perioperative nurse to take regarding this explanted hardware?

▸ Why B is the answer

Explanted orthopedic hardware is considered medical waste and a potential biohazard. Institutional policy typically requires sending it to pathology for documentation and gross examination before it can be decontaminated and released. Option B is correct because it ensures proper chain of custody and documentation. Option A and Option D are incorrect because giving unsterilized or merely soaked hardware directly to the patient or family violates biohazard safety protocols. Option C is incorrect because hardware should be sent dry; formalin is unnecessary for metal implants and poses an exposure risk to staff.

🔑 Key takeaway

Explanted hardware must undergo gross pathological examination and institutional decontamination before release to a patient.

Question 2

Prior to a lumbar spinal fusion, the circulating nurse is verifying the implants against the surgeon's preference card and notes that the backup pedicle screws are missing from the vendor trays.

▸ Why A is the answer

Verification of implants includes ensuring that both primary and backup sizes are available before the incision is made. The surgeon must be notified immediately to determine if it is safe to proceed without the backups. Allowing the procedure to begin relies solely on the primary screws which poses a severe risk if a screw is dropped or fails during insertion. Requesting the vendor to retrieve the screws during surgery risks prolonged open wound time if the backup is needed before the vendor returns. Instructing the scrub person to prepare alternative devices inappropriately bypasses the surgeon's clinical decision regarding hardware selection.

🔑 Key takeaway

Both primary and backup implants must be verified and communicated to the surgeon before incision.

Question 3

A perioperative nurse is preparing for a total joint arthroplasty. While donning a surgical mask, the nurse crosses the bottom ties over the top ties at the back of the head.

▸ Why A is the answer

Crossing the ties of a surgical mask creates a gaping effect at the cheeks, which allows unfiltered air to escape and enter the sterile field. Option A correctly identifies this risk and prompts the necessary intervention. Option B is incorrect because crossing ties fundamentally prevents a snug fit. Option C is incorrect because ear loops generally do not provide the secure, customizable fit required in the operating room environment. Option D is incorrect because simply tightening the top strings will not correct the structural gap caused by the crossed ties.

🔑 Key takeaway

Crossing surgical mask ties creates side gaps that compromise the filtration seal.
