How long should I study for the test?
Plan for two to three months of consistent preparation. This gives you enough time to review all eight domains and complete multiple rounds of practice questions without burning out.
Which topics should I study first?
Start with Management of Intraoperative Activities: Patient Care and Safety. This section makes up 25% of the test. Mastering this domain early gives you a strong foundation for the rest of your review.
What is the second most important topic to cover?
Focus next on Infection Prevention and Control of the Environment, Instrumentation, and Supplies. This domain accounts for 16% of the test. Combined with intraoperative safety, these two areas cover nearly half of your assessment.
How many questions will I face?
You will answer 200 multiple-choice questions. Only 185 of these are scored. The remaining 15 are unscored pretest items mixed randomly throughout your session.
How much time do I have to finish?
You have exactly 3 hours and 45 minutes to complete all 200 items. This gives you slightly over one minute per question. Pace yourself during your study sessions to match this timing.
What is the best way to prepare for the question format?
Drill scenario-based questions daily. We offer 2200+ practice questions to help you get used to applying perioperative nursing concepts to realistic patient situations.
Do I need to memorize the exact passing score?
No. The scoring system is scaled based on difficulty. For the exact raw score needed to pass your specific test version, check the Competency & Credentialing Institute (CCI) official handbook.
How heavily is the pre- and postoperative assessment domain weighted?
Pre/Postoperative Patient Assessment and Diagnosis makes up 15% of your score. This is the third-largest domain, making it a critical part of your study schedule.
What about emergency situations and professional accountability?
Emergency Situations accounts for 10% of the test. Professional Accountability is the smallest section at just 6%. Review these areas toward the end of your study plan.
Where do I take the test?
You can test in person at a designated testing center or take it from home via a remote proctor. Choose the environment where you focus best.
How do I maintain my credential after I pass?
You must renew every five years. You can do this by retaking the test, earning 300 professional-activity points, or completing 125 contact hours. At least 75 of those hours must be specific to perioperative practice. Starting January 1, 2026, per-category point limits will be removed.

Start by finding your gaps

Every honest study plan starts with knowing what you don't know. Try three practice questions. The app has 2,200+, timed and scored.

Question 1

A scrub nurse sustains a percutaneous injury with a contaminated suture needle during a trauma laparotomy on a patient with unknown HIV status. What is the most appropriate initial action?

β–Έ Why A is the answer

The immediate action after a percutaneous exposure is to wash the site with soap and water. Squeezing the site (Option B) is contraindicated as it can promote tissue damage and increase pathogen uptake. While notifying the charge nurse (Option C) and testing the source patient (Option D) are required steps in the exposure control plan, they must occur only after the wound is properly cleansed.

πŸ”‘ Key takeaway

Immediate cleansing with soap and water is the first step following any percutaneous bloodborne exposure.

Question 2

A circulating RN observes a certified surgical technologist independently drawing up unlabeled medication from a vial held by the anesthesia provider during a rapid trauma laparotomy.

β–Έ Why B is the answer

The RN must intervene because the surgical technologist's scope requires the RN to verify all medications transferred to the sterile field, regardless of urgency. Option B is correct as it ensures patient safety and adherence to scope. Option A is incorrect because emergencies do not negate the need for proper medication verification. Option C is wrong because passive documentation fails to prevent a potential immediate medication error. Option D is incorrect because unsterile vials cannot be placed directly onto the sterile backtable.

πŸ”‘ Key takeaway

Perioperative nurses must verify all medications transferred to the sterile field regardless of procedural urgency.

Question 3

A patient with advanced Alzheimer's disease who is oriented only to self is admitted to the preoperative area. The patient is undergoing a right hip arthroplasty. Which approach is best for documenting the preoperative neurological baseline?

β–Έ Why D is the answer

Option D is correct because establishing a clear cognitive baseline helps the team recognize postoperative delirium, and a legal guardian is necessary to provide an accurate health history when the patient cannot. Option A is inaccurate because the scenario specifies the patient is oriented to self, so documenting them as fully disoriented misrepresents their baseline. Option B is incorrect because a patient with advanced Alzheimer's who is only oriented to self lacks the capacity to provide informed consent. Option C is incorrect because the perioperative nurse must independently verify and document the neurological baseline immediately prior to surgery, rather than relying on old chart notes that may not reflect the patient's current state.

πŸ”‘ Key takeaway

Establishing a cognitive baseline helps identify postoperative delirium, and collateral history is required for cognitively impaired patients.
