CNOR Practice Test
Updated for October 2026CNOR Meaning
The CNOR credential isnβt for nurses just starting out in the perioperative field; itβs typically earned by OR nurses who have already accumulated a certain level of skill and experience. Having the certification allows them to succinctly demonstrate that fact.
In addition to passing the exam, nurses must maintain an unrestricted RN license in the state where they practice and currently work full- or part-time in a perioperative clinical setting (or nursing education, administration, or research). They also must have at least two years of experience in the OR, including more than 1,200 hours of intra-operative time.
AORN offers a variety of resources to help nurses prepare for the CNOR exam. For example, the article "Surgical specimen management errors in the preanalytic phase: perioperative nursing implications"44 provides an overview of different types of specimen management errors and discusses how these errors can affect patients. It also discusses ways that perioperative nurses can prevent these errors. The CNOR certification is a significant achievement in the nursing profession and is a mark of quality care for patients.

Sample CNOR - Certification Exam Practice Questions
Try these questions from our free CNOR - Certification Exam practice tests. The correct answer and an explanation follow each question.
Which action BEST reduces the risk of surgical site infection (SSI) related to hair removal?
- A. Shaving the operative site the night before surgery with a safety razor
- B. Clipping hair at the operative site immediately before the procedure if removal is necessary
- C. Using depilatory cream 12 hours before the scheduled incision
- D. Performing no hair removal at any time regardless of hair density
Answer: B. Clipping hair at the operative site immediately before the procedure if removal is necessary
Clipping immediately before surgery is preferred over shaving because razors create micro-abrasions that harbor bacteria and increase SSI risk.
Which principle guides the CNOR's role in maintaining the sterile field during a surgical procedure?
- A. Any item of doubtful sterility is considered contaminated
- B. A sterile field can be re-established after brief contamination
- C. Sterile items may touch non-sterile items if contact is brief
- D. The surgeon determines sterility status of items in the field
Answer: A. Any item of doubtful sterility is considered contaminated
A fundamental principle of aseptic technique is that any item whose sterility is uncertain must be treated as contaminated.
A patient develops stridor immediately upon extubation. The FIRST priority nursing action is to:
- A. Administer IV dexamethasone
- B. Call the surgeon
- C. Apply 100% oxygen and assess airway patency
- D. Position the patient supine
Answer: C. Apply 100% oxygen and assess airway patency
Stridor indicates partial airway obstruction; immediate application of oxygen and airway assessment are the first priorities.
A patient who received spinal anesthesia 24 hours prior calls the hospital complaining of a severe headache that is significantly worse when sitting up and relieved by lying flat. The perioperative nurse should recognize these symptoms as characteristic of which complication?
- A. Meningitis
- B. Anesthetic neurotoxicity
- C. Post-dural puncture headache (PDPH)
- D. Subdural hematoma
Answer: C. Post-dural puncture headache (PDPH)
The hallmark symptom of a post-dural puncture headache (PDPH) is its positional nature; it intensifies in an upright position and is alleviated by lying supine. This is caused by the leakage of cerebrospinal fluid from the puncture site in the dura mater, which reduces the fluid cushion around the brain.
