The May 2026 handbook uses eight content areas; the largest is Intraoperative Patient Care and Safety at 25%. The application is $475 including the first attempt, and retakes are $175 with at least 30 days between attempts during the 12-month eligibility period.

Sample CNOR Practice Questions

Try these sample questions to test your CNOR exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 210+ question experience with AI tutoring.

1Which information is MOST important for the perioperative nurse to obtain during the preoperative patient assessment regarding previous surgeries?

A.The names of all previous surgeons

B.Any complications experienced during prior anesthetics or surgeries

C.The exact dates of all previous surgical procedures

D.The hospital locations where previous surgeries were performed

Explanation: Previous surgical complications, especially those related to anesthesia, airway management, bleeding, or infections, are critical for planning safe perioperative care. This information helps the team anticipate potential risks and implement preventive measures. While dates and surgeon names are relevant, complications directly impact patient safety and surgical planning.

2A patient scheduled for elective surgery reports taking warfarin at home. What is the nurse's priority action?

A.Cancel the surgery immediately

B.Notify the surgeon and anesthesia provider about the anticoagulant use

C.Instruct the patient to stop taking the medication immediately

D.Document the medication and proceed with standard preparation

Explanation: Warfarin and other anticoagulants significantly increase bleeding risk during surgery. The perioperative nurse must communicate this information to the surgeon and anesthesia provider so they can determine if the surgery needs to be postponed, if bridging therapy is required, or if special intraoperative precautions are needed. Never instruct patients to stop anticoagulants without physician orders.

3During preoperative assessment, a patient reveals they have been taking herbal supplements including ginkgo biloba and garlic. Why is this significant?

A.These supplements are contraindicated with all anesthetic agents

B.Herbal supplements can increase bleeding risk and interact with anesthetics

C.Supplements must be discontinued at least one year before surgery

D.The supplements will interfere with surgical equipment

Explanation: Many herbal supplements, including ginkgo biloba, garlic, ginseng, and fish oil, have anticoagulant or antiplatelet effects that can increase surgical bleeding risk. Some herbs also interact with anesthetic agents. The nurse should document all supplements and notify the surgical team, as many need to be discontinued 1-2 weeks before surgery.

4A patient with a history of malignant hyperthermia is scheduled for surgery. What is the MOST important preoperative intervention?

A.Ensure the operating room is equipped with a malignant hyperthermia cart and dantrolene

B.Cancel all surgical procedures for this patient

C.Administer prophylactic dantrolene to all patients preoperatively

D.Use only local anesthesia for all procedures

Explanation: Malignant hyperthermia is a life-threatening reaction to certain anesthetic agents. The perioperative nurse must ensure the OR has a malignant hyperthermia cart with dantrolene (the specific antidote), and that the anesthesia provider uses trigger-free anesthetics. Surgery does not need to be cancelled, but specific precautions are essential.

5Which patient statement during preoperative assessment warrants immediate notification of the anesthesia provider?

A.I had difficulty waking up after my last surgery

B.I had severe nausea after anesthesia five years ago

C.I have a family history of high blood pressure

D.I am nervous about the surgical procedure

Explanation: Difficulty waking up or prolonged emergence from anesthesia may indicate pseudocholinesterase deficiency, a genetic condition that affects metabolism of certain anesthetic drugs. This is critical information for the anesthesia provider to plan safe anesthetic management. While nausea and anxiety are important to document, they are not as immediately life-threatening.

6For a patient undergoing major abdominal surgery, which preoperative laboratory value would be MOST concerning to the surgical team?

A.Hemoglobin of 11.5 g/dL

B.Potassium level of 5.8 mEq/L

C.White blood cell count of 12,000/mm³

D.Platelet count of 130,000/mm³

Explanation: A potassium level of 5.8 mEq/L indicates hyperkalemia, which is significantly above the normal range (3.5-5.0 mEq/L). Hyperkalemia can cause life-threatening cardiac arrhythmias, especially during surgery and anesthesia. This requires immediate intervention before proceeding with elective surgery.

7A patient's preoperative chest X-ray reveals an enlarged cardiac silhouette. What is the nurse's appropriate action?

A.Document the finding and proceed with surgery as scheduled

B.Notify the surgeon and anesthesia provider of the finding

C.Cancel the surgery without notifying the physician

D.Request a repeat X-ray immediately

Explanation: An enlarged cardiac silhouette may indicate cardiomegaly or pericardial effusion, which can affect anesthesia management and surgical risk. The perioperative nurse should communicate this finding to the surgical team so they can assess whether additional cardiac evaluation is needed before proceeding with surgery.

8Which preoperative laboratory finding requires postponement of elective surgery?

A.Sodium level of 132 mEq/L

B.Blood glucose of 180 mg/dL in a diabetic patient

C.Hemoglobin of 7.2 g/dL

D.Creatinine of 1.3 mg/dL

Explanation: A hemoglobin of 7.2 g/dL indicates severe anemia (normal is 12-16 g/dL for women, 13.5-17.5 g/dL for men). Elective surgery should be postponed to allow for investigation of the cause and possible transfusion, as significant blood loss during surgery could be life-threatening. Most surgeons require hemoglobin above 8-10 g/dL for elective procedures.

9The nurse is reviewing an ECG from a preoperative patient and notes new onset atrial fibrillation with a ventricular rate of 140. What is the priority action?

A.Proceed with surgery as the rhythm is stable

B.Administer beta-blockers per protocol

C.Notify the anesthesia provider and surgeon immediately

D.Document the rhythm and continue with routine preparation

Explanation: New onset atrial fibrillation with a rapid ventricular rate is a significant finding that increases surgical risk and requires cardiology evaluation. The anesthesia provider and surgeon must be notified to determine if the surgery should proceed or if the cardiac issue needs stabilization first.

10A patient has a preoperative INR of 1.8. For most major surgeries, what is the desired INR range?

A.Less than 1.5

B.Between 2.0 and 3.0

C.Between 3.0 and 4.0

D.Any value below 2.5 is acceptable

Explanation: For most major surgeries, the INR should be less than 1.5 to minimize bleeding risk. An INR of 1.8 may be acceptable for minor procedures but could increase bleeding risk for major surgery. The nurse should communicate this to the surgeon, who will determine if reversal is needed or if the surgery can proceed with modified technique.
