CNOR Practice Questions: What CCI Offers, What to Avoid, and Five OR Scenarios Explained

Search for CNOR practice questions and you'll find everything from CCI's own material to files that promise the "real" exam. The first kind teaches you how CCI asks questions; the second can cost you the credential. Below: what CCI offers, what to avoid, five original questions with the reasoning and source behind each answer, and a way to review practice so it changes your result.

Official CNOR practice: what CCI offers

Checked on CCI's pages and in the CNOR handbook (version 5.2026) on October 27, 2026:

The CNOR page also links a third-party prep app and a prep book. CCI's disclaimer applies to all of it: CCI "does not require or endorse any specific study guides, review products, or training courses," and using review materials, "CCI or otherwise," doesn't imply passing.

What CCI's five CNOR sample questions show

The handbook says the samples "represent similar content" to the exam and are meant to show its format. Read them in the handbook itself. Without reproducing them, here is what they show:

• Short stems. Each is one or two lines, with four answer choices and no long clinical story
• Mostly recall. Three ask for anatomy or a normal physiological value. One asks which type of facility plan covers a system breakdown, and one asks which intervention is contraindicated in a neurological scenario
• No answers. The handbook gives no key, so work out each answer and check it against the references; that habit is the one the exam rewards

CCI's five free practice questions add answers and rationales. Together they are a ten-question sample: enough to see the style, not enough to judge readiness.

Free CNOR practice beyond CCI, and what to avoid

The free CNOR practice questions on this site are 20 original questions with an explanation for every answer, and they need no account. They are Passy's own items, not CCI's. When you want volume, full prep planned for launch adds 1,700 original CNOR questions.

For anything else, two checks protect you:

• Is it original? The handbook says copying or retaining test questions, or "transmitting the test questions in any form to other individuals, organizations, or study groups," forfeits your right to have the exam scored and may lead to civil prosecution and disciplinary action. It lists cheating and "causing, creating, or participating in an examination irregularity" among the grounds for revoking certification. A file advertised as "real" or "recalled" CNOR questions is a risk to your credential, not a shortcut
• Is it current? Today's exam has 200 questions, 185 scored, across CCI's seven subject areas, with task and knowledge statements updated in December 2023. A resource built on "170 scored questions" or another outline doesn't match CCI's current handbook, and CCI plans a six-area exam for 2027, described in the CNOR exam format guide

Five original CNOR-style questions, written by Passy

These are teaching items written for this guide. They aren't CCI items and don't come from any exam. Each answer cites the source it rests on.

Question 1: reprocessing a laryngoscope blade (Infection Prevention and Control)

Under CDC's Spaulding classification, what is the minimum processing a reusable laryngoscope blade needs between patients?

• A. Sterilization, because it is used during an anesthetic procedure
• B. High-level disinfection, because it contacts mucous membranes
• C. Low-level disinfection, because it touches only intact skin
• D. Cleaning alone, because it never enters a sterile body cavity

Keyed answer: B. CDC's rational approach page defines semicritical items as those that contact mucous membranes or nonintact skin, names laryngoscope blades among them, and says they "minimally require high-level disinfection." A applies the process for critical items, which enter sterile tissue or the vascular system; it isn't the minimum. C describes noncritical items. D skips disinfection entirely. The CNOR infection prevention review covers the full scheme.

Question 2: one syringe on the field (Patient Care and Safety)

The scrub person draws local anesthetic into a syringe on the sterile field. It is the only medication on the field, and the surgeon will inject it in about 10 minutes. What does the Joint Commission require?

• A. No label is needed, since it is the only medication on the field
• B. Label it as soon as it's prepared, verified aloud and visually by two people
• C. Label it only if it will sit on the field for longer than one hour
• D. Label it after the procedure, once the final count is complete

Keyed answer: B. The Joint Commission's 2026 standard requires labeling all medications on and off the sterile field "even if there is only one medication being used," labeling each one as soon as it is prepared unless it is immediately administered, and verbal and visual verification by two qualified people whenever the person preparing it isn't the person giving it. A contradicts the single-medication rule. C and D invent timing the standard doesn't allow.

Question 3: a wet skin prep (Emergency Situations)

After an alcohol-based skin prep for a neck procedure, the prep is still visibly wet when the surgeon asks to drape and start electrocautery. What should the nurse do?

• A. Drape right away, since the drapes will cover the wet prep
• B. Wait until the prep has dried completely before draping
• C. Allow cautery on a low setting while the prep finishes drying
• D. Leave the used prep materials until the end of the case

Keyed answer: B. The Joint Commission's Sentinel Event Alert 68 names "failure to allow alcohol-based field preparations to completely dry" and improper disposal of prep material among the contributing factors in surgical fires, and calls alcohol-based preps common fuel sources when not allowed to completely evaporate. Draping (A) doesn't remove the fuel, a low setting (C) is still an ignition source, and D leaves prep material behind.

Question 4: numb lips after local infiltration (Emergency Situations)

Shortly after the surgeon infiltrates a large volume of bupivacaine during a procedure under monitored sedation, the patient says her lips feel numb, she has a metallic taste and her ears are ringing. What do these findings most likely indicate?

• A. Early signs of local anesthetic systemic toxicity
• B. An expected effect of the infiltrated anesthetic
• C. Anxiety that will settle with reassurance alone
• D. Sedation that is wearing off sooner than planned

Keyed answer: A. FDA-approved bupivacaine labeling on DailyMed lists numbness and tingling of the mouth and lips, metallic taste and tinnitus among the possible early warning signs of central nervous system toxicity, and warns that delayed management may lead to acidosis and cardiac arrest. B, C and D all explain the signs away. The next steps are in the CNOR emergency situations review.

Question 5: classifying the wound (Communication and Documentation)

A patient has an elective laparoscopic cholecystectomy for symptomatic gallstones. The gallbladder is removed intact, with no spillage, no infection found and no break in technique. How should the wound be classified?

• A. Class I, clean
• B. Class II, clean-contaminated
• C. Class III, contaminated
• D. Class IV, dirty-infected

Keyed answer: B. CDC's 1999 surgical site infection guideline defines clean-contaminated wounds as those entering the respiratory, alimentary, genital or urinary tract under controlled conditions, and specifically includes biliary tract operations when there is no infection or major break in technique. CDC's NHSN manual (January 2026) doesn't allow gallbladder surgery to be recorded as clean, which rules out A. C would need gross spillage or a major break, and D an existing infection or perforation.

If explanations like these help, planned CNOR practice explains every option the same way, across all eight weighted parts of the outline.

How to review CNOR practice so it changes your result

A practical approach, not a CCI rule:

1. Time yourself. The exam's average pace is about 67 seconds a question (Passy's arithmetic: 225 minutes for 200 questions).
2. Explain every option. Say why the keyed answer is right and why each other option is wrong. A right answer for the wrong reason is still a gap.
3. Log every miss twice. Note the subject area and the reason: missing knowledge, a misread stem, or an answer that matched your unit's routine instead of the references.
4. Check against the references. CCI's CNOR page says exam material is pulled from AORN's Guidelines for Perioperative Practice and three textbooks. When a rationale conflicts with your facility's practice, look it up there.
5. Mix the areas. The exam doesn't announce the topic, so after a few area-by-area sets, switch to mixed sets.
6. Track trends, not one score. No practice score converts to CCI's scaled 620; the CNOR passing score guide explains why. Watch whether your misses in each area shrink.

For variety once the basics are in place, full prep at launch also plans challenges such as No-Miss Run and Hard Mode.

Your next step with CNOR practice questions

Read CCI's five handbook samples and write a one-line reason for each answer before checking the references. Then take the 20 free questions timed, sort your misses by subject area and reason, and use the CNOR study plan guide to send your next week's hours to the areas that cost you most.
