The CNOR (Certified Perioperative Nurse) is a nursing certification awarded by CCI.
CCI publishes the official exam outline, eligibility rules and fees — see CCI's official page before you book.
In our 1050-card CNOR deck the heaviest topics are Procedures (26%), Management (19%), Safety (11%) — that is how this deck is weighted, not the official blueprint, so use it to plan practice and check CCI's exam outline for the real weighting. This guide shows where the material gets hardest, which topics to practise first, and a 5-step plan built on active recall.

These are genuine cards from the heaviest-weighted topics above. Answer each one before you reveal it — that is what active recall means in practice.
A 65-year-old patient reports they can walk up two flights of stairs without stopping or experiencing chest pain. According to AHA/ACC guidelines, how many METs does this represent, and what is the clinical significance for perioperative risk?
Show answer →Functional capacity is measured in Metabolic Equivalents (METs). Climbing two flights of stairs or walking 4 mph equals ≥4 METs. Clinical Significance: Patients with ≥4 METs generally have a lower risk of perioperative Major Adverse Cardiac Events (MACE). If a patient cannot achieve 4 METs (e.g., unable to walk a block or do light housework), they are at higher risk and may require further cardiac testing, especially for high-risk procedures. CCI Exam Tip: CCI often tests the 4 MET threshold as the dividing line for requiring further diagnostic workup versus proceeding to surgery.
During preoperative assessment, a patient has a STOP-BANG score of 5. What is the perioperative nurse's priority action regarding this score, and what does it indicate for the intraoperative phase?
Show answer →A STOP-BANG score of 5-8 indicates a high risk for moderate-to-severe Obstructive Sleep Apnea (OSA). Priority: Notify the anesthesia provider and ensure the availability of difficult airway equipment and post-op CPAP. Intraoperatively, these patients are highly sensitive to opioids and neuromuscular blocking agents, increasing the risk of airway collapse. Clinical Pearl: The STOP-BANG criteria include Snoring, Tiredness, Observed apnea, Pressure (BP), BMI (>35), Age (>50), Neck circumference (>40cm), and Gender (Male). CCI Focus: Recognize that a score ≥3 requires evaluation, but ≥5 is high risk. Do not assume the surgery must be canceled; instead, focus on resource readiness and monitoring requirements.
Which preoperative laboratory finding in a renal failure patient is the most critical red flag for the perioperative nurse regarding the risk of intraoperative metabolic acidosis?
Show answer →A low serum bicarbonate (HCO3-) level (typically < 22 mEq/L). In renal failure, the kidneys cannot excrete hydrogen ions or regenerate bicarbonate, leading to metabolic acidosis. This is exacerbated by the respiratory depressant effects of anesthesia, which can lead to a combined acid-base imbalance. CCI Exam Focus: Acid-base balance is a high-yield topic. A baseline acidosis reduces the patient's physiological reserve to handle the stress of surgery and anesthesia-induced hypoventilation.

These 3 topics alone account for roughly 56% of our 1050-card CNOR deck. Time spent here pays off more than anywhere else.
Answer questions before flipping to the answer — that struggle is what builds retention. Start with the 30 free CNOR cards, then work through the full deck one category at a time.
After a full pass, re-drill only the cards you missed. Small categories are quick wins — closing a weak topic can be an afternoon's work.
Our deck rates 520 cards as hard. If those feel comfortable in your final two weeks, you are studying above test level.
