2,200+ practice questions with rationales on iOS

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 patient scheduled for an emergency appendectomy suddenly reports a severe reaction to avocados during the preoperative interview. What is the most appropriate action for the perioperative nurse?

β–Έ Why B is the answer

There is a well-documented cross-reactivity between latex and certain foods, particularly avocados, bananas, chestnuts, and kiwis. Because this patient is presenting for an emergency procedure and reports a severe reaction to avocados, the nurse must assume a latex allergy and immediately initiate a latex-safe environment. Option B is correct because implementing strict precautions prevents a potentially fatal anaphylactic reaction. Option A is incorrect; delaying an emergency appendectomy for allergy testing is clinically unsafe and impractical. Option C is incorrect because epinephrine is a treatment for active anaphylaxis, not a prophylactic measure prior to surgery. Option D is incorrect because proceeding with a standard setup exposes the patient to latex, violating safety protocols and risking severe patient harm.

πŸ”‘ Key takeaway

A reported allergy to highly cross-reactive foods requires immediate implementation of latex precautions.

Question 2

A patient is scheduled for an elective cholecystectomy, but during the pre-procedure verification, the nurse notes that the history and physical is missing from the chart. How should the nurse respond?

β–Έ Why C is the answer

When a history and physical is missing for a patient scheduled for an elective cholecystectomy, the Universal Protocol mandates that all relevant documents be present and reviewed before starting. The procedure must be suspended until the H&P is located or recreated. Option A violates safety standards by proceeding without full clinical context. Option B relies solely on patient recall, bypassing required medical documentation. Option D is incorrect because a brief note does not meet the comprehensive regulatory requirements for an H&P.

πŸ”‘ Key takeaway

The Universal Protocol mandates that all relevant documents be present and reviewed before starting a procedure.

Question 3

Following a laparoscopic bowel resection for perforated diverticulitis, the surgical team is preparing the soiled case cart for transport back to the sterile processing department. The scrub person has placed all hinged instruments in an open position.

β–Έ Why A is the answer

Point-of-use preparation is critical to prevent bioburden from drying on instruments, especially after contaminated cases like a bowel resection. Spraying with an enzymatic pretreatment solution keeps soil moist and begins the breakdown process, which is essential for effective decontamination. Case carts should be closed or covered with a biohazard cover, not a sterile drape, as the contents are now contaminated. Biohazard labels must be clearly visible on the outside of the cart to alert transport staff, not hidden on the inside doors. Heavy trays should always be placed on the bottom shelves to prevent physical damage to lighter, more delicate instrument trays during transport.

πŸ”‘ Key takeaway

Point-of-use instrument care requires enzymatic pretreatment to prevent bioburden drying before transport.
