How much time do I have to finish?
You get exactly 3 hours and 45 minutes to complete the session. Plan your pacing to answer about one item per minute.
What is the testing format?
Every item is multiple-choice. You will not see fill-in-the-blank, select-all-that-apply, or essay prompts.
Where do I take the test?
You have two options. You can schedule an in-person appointment at a physical testing center, or you can choose remote proctoring from your own computer.
What subject areas are covered?
The content spans eight domains. The largest section is Intraoperative Patient Care & Safety at 25%. Infection Prevention & Control makes up 16%, and Pre/Postoperative Assessment & Diagnosis accounts for 15%.
What are the smaller content domains?
Communication & Documentation is 11%, Emergency Situations is 10%, and Intraoperative Personnel/Services/Materials is 9%. Plan of Care Development covers 8%, and Professional Accountability is 6%.
What is the passing score?
The exact passing threshold varies by test form. Check the Competency & Credentialing Institute (CCI) official handbook for current scoring methodologies.
How much does it cost to register?
Pricing depends on your membership status and facility affiliations. You must consult the Competency & Credentialing Institute (CCI) official handbook to find the exact registration fees.
How should I prepare for these domains?
Focus your study time heavily on intraoperative care and infection prevention, as they carry the most weight. We offer over 2200 practice questions to help you drill these specific categories.
What are the eligibility rules to sit for this certification?
You need a current, unrestricted RN license. You must also have 2 years and 2,400 hours of perioperative nursing experience, with at least 1,200 of those hours in the intraoperative setting within the past 5 years.

What the questions actually look like

The format is one thing; the questions are another. Here are three realistic examples. The app has 2,200+, timed and scored.

Question 1

A trauma patient with a full stomach requires emergency surgery. The anesthesia provider instructs the nurse to initiate cricoid pressure while the patient is still awake and breathing spontaneously prior to induction.

▸ Why A is the answer

When initiating cricoid pressure on an awake patient prior to induction, you should apply approximately ten Newtons (about 1 kg) of force. This amount is enough to begin occluding the esophagus without causing the patient severe discomfort, coughing, or airway obstruction while they are still conscious. Applying thirty or forty Newtons (Options B and D) is too forceful for an awake patient and is only appropriate after the loss of consciousness. Applying pressure to the thyroid cartilage (Options C and D) is incorrect because the thyroid cartilage does not form a complete ring and will not effectively compress the esophagus against the cervical vertebrae.

🔑 Key takeaway

Awake patients should receive only ten Newtons of cricoid pressure to prevent coughing and airway obstruction.

Question 2

Thirty minutes before a complex spinal fusion with vendor loaner instrumentation, the circulator discovers that the pedicle screw tray is missing from the case cart. The patient is currently in the preoperative holding area.

▸ Why B is the answer

Patient safety dictates that all necessary equipment, especially critical loaner instrumentation for a complex spine case, must be verified as present and sterile before the patient enters the operating room. Notifying the surgeon and delaying transfer prevents the patient from undergoing unnecessary anesthesia while waiting for supplies. Proceeding with induction risks prolonged anesthesia time if the tray is significantly delayed. Substituting a standard hospital set is unsafe because it may not be compatible with the vendor's specific implants. Having the vendor bring a replacement tray directly into the room bypasses required sterile processing biological clearance and facility sterilization protocols.

🔑 Key takeaway

Verify all critical instrumentation is present and sterile before transferring the patient to the OR.

Question 3

During a prolonged abdominal exploratory laparotomy, the surgeon temporarily stops using the active electrosurgical active electrode while inspecting the bowel. To prevent a surgical fire, how should the scrub person manage this device?

▸ Why A is the answer

During a prolonged abdominal exploratory laparotomy, the active electrosurgical active electrode must be managed carefully to prevent accidental activation and subsequent thermal injury or fire. The perioperative nurse must ensure the device is placed in a designated safety holster whenever it is not actively being used by the surgeon. Handing the electrode to the surgical technologist immediately (Option B) is impractical during a dynamic procedure and increases the risk of accidental activation during the transfer. Disconnecting the electrode from the generator (Option C) disrupts the surgical workflow and is unnecessary if the holster is utilized correctly. Positioning the active electrode on a dry sterile towel (Option D) is a dangerous practice, as the towel provides no protection against accidental activation and can easily serve as a fuel source if the device sparks.

🔑 Key takeaway

Active electrosurgical electrodes must be stored in a non-conductive safety holster when not in immediate use.
