ONCC CNOR Certification Sample Questions

The CC Institute Certified Perioperative Nurse Certification Sample Question Set on this page is designed to familiarize you with the actual ONCC CNOR exam format and question types. These sample questions help you understand how questions are structured and what to expect on test day. While they provide a useful starting point, they represent only a limited preview of the real exam experience.

These sample questions are intended for evaluation and familiarization only. To understand exam style, pacing, and reasoning patterns more clearly, we recommend trying our online sample practice environment. If you are preparing for the CC Institute Certified Perioperative Nurse (CNOR) and want to assess your readiness more rigorously, structured, timed, scenario-based practice is recommended. This approach aligns with the cognitive demands and professional expectations typically associated with perioperative registered nurses, perioperative nursing educators and administrators, perioperative nursing researchers working in settings such as hospital operating rooms, ambulatory surgical and perioperative care settings, perioperative education administration and research settings.

The demo introduces core concepts, while full-length premium simulations provide deeper, scenario-based coverage that more closely reflects the actual cognitive demands of the CC Institute Certified Perioperative Nurse exam, particularly in areas such as perioperative patient assessment and individualized care planning, intraoperative patient care and safety management, infection prevention communication emergency response and professional accountability. You can use these sample questions as a starting point, then progress to the ONCC CNOR Certification Practice Exam for stronger readiness. Our premium simulations are designed to mirror real exam conditions, helping you refine reasoning, pacing, and decision-making before your official exam attempt.

ONCC CNOR Sample Questions:

01. A department is considering asking patients to bathe with an antiseptic preparation before surgery. A colleague objects that this cannot help because the skin will be prepared in the operating room anyway.
What is the most defensible judgment?
a) The practice should be adopted for implant procedures, and for long cases, where infection has the greatest consequence
b) The objection is sound, since the surgical preparation is performed to a standard that makes prior bathing irrelevant
c) The practice should be adopted because it improves the patient's engagement in their own preparation for surgery
d) Reducing the skin's microbial load before arrival lowers the burden the operating room preparation has to overcome

02. A patient with advanced liver disease is scheduled for an abdominal procedure. The preoperative record notes easy bruising and a history of prolonged bleeding after a dental extraction.
How should the perioperative nurse act on this information?
a) Report the bleeding history to the team and confirm what blood products have been arranged and how quickly they can be obtained
b) Request that the surgeon obtain consent specifically for transfusion, since the risk of requiring products is elevated
c) Report the findings to the postanesthesia nurse and the ward team afterward, so they are aware of the increased bleeding risk
d) Arrange for the patient to receive vitamin K before the procedure, since deficiency underlies the impaired clotting

03. A security alert requires the facility to be placed in lockdown while cases are in progress in the surgical suite.
What is the perioperative nurse's role during this?
a) Follow the department's role in the plan, and prepare to evacuate the patient if that is instructed by the security team
b) Contact the security team for information about the nature of the threat before taking any action
c) Follow the department's role in the plan and secure the room while maintaining care of the patient
d) Complete the procedure as quickly as is safe, so that the patient can be moved to a secure area

04. An electronic perioperative record automatically populates several assessment fields with values carried forward from the previous entry. A colleague suggests this saves time and should be relied on where the patient's condition is unchanged.
What is the most defensible judgment?
a) The feature should be disabled entirely, since fields that are populated automatically cannot form part of an accurate contemporaneous record
b) Each populated value must be verified against the patient before it is accepted, because the record asserts an observation was made
c) Carried-forward values are acceptable where the assessment interval is short and no change is expected
d) The values may be accepted provided the nurse signs the entry, since the signature attests to its accuracy

05. During a lengthy procedure using continuous irrigation of a closed cavity, the circulating nurse is tracking the volume of solution instilled against the volume returned.
Why is this difference the measurement that matters, rather than the total volume used?
a) Because the difference shows how much irrigation has been lost to the drapes and the floor during the case
b) Because the difference indicates how effectively the drainage system is clearing the cavity of debris
c) Because the difference allows the volume of blood lost to be calculated once the irrigation is accounted for
d) Because the difference estimates how much fluid has entered the patient's circulation through the exposed surfaces

06. Intraoperative imaging using ionizing radiation will be required repeatedly during a procedure, and the circulating nurse must remain in the room throughout.
Which combination of measures most reduces the nurse's exposure?
a) Wearing the protective garments provided, standing behind the imaging unit rather than beside it, and wearing a monitoring badge
b) Wearing the protective garments provided, ensuring that a thyroid shield is available, and recording the number of exposures
c) Wearing the protective garments provided, standing as far from the source as the role allows, and limiting the time spent close to it
d) Wearing the protective garments provided, leaving the room for each exposure, and confirming the settings with the radiologic technologist

07. The surgeon requests a local anesthetic for infiltration during a procedure. Two preparations of the same agent are available, one containing a vasoconstrictor and one without.
What must occur before the agent is delivered to the sterile field?
a) The nurse selects the preparation containing the vasoconstrictor, since it prolongs the effect and reduces bleeding at the infiltration site
b) The circulating nurse records both preparations in the medication record so that whichever is used is already documented
c) The scrub person draws up both preparations so that either is available at the moment the surgeon asks for it
d) The surgeon specifies which preparation is required, and the nurse and scrub person confirm the label against that request

08. Why does the perioperative nurse keep the anesthetized patient covered except for the area required for the procedure?
a) It preserves the patient's dignity and limits heat loss, neither of which the patient can attend to
b) It reduces the number of items that need to be removed at the end of the procedure
c) It ensures that monitoring devices remain in contact with the skin throughout the procedure
d) It prevents contamination of the field from the skin adjacent to the incision, and from the bed, before draping is complete

09. Specimens preserved in a fixative solution are being handled and transferred at the end of a procedure.
Which practice addresses the hazard the fixative itself presents?
a) Filling the containers away from the sterile field, labeling each one before the specimen is placed, and transporting them upright
b) Using the smallest volume of fixative that will cover the specimen, and sealing each container immediately after filling
c) Transferring the containers in a closed carrier and confirming that the receiving laboratory is expecting them
d) Filling the containers where vapor is controlled, wearing eye and hand protection, with the spill kit within reach

10. A colleague asks the perioperative nurse to sign off a competency assessment for a skill the colleague has performed only once, explaining that the paperwork is due today.
How should the nurse respond?
a) Refer the colleague to the educator, since competency assessment is properly the educator's responsibility
b) Decline, and offer to complete the assessment properly once the colleague has had the practice it requires
c) Sign the assessment, noting on the record that it is based on a single observed performance
d) Sign the assessment and arrange to observe the colleague performing the skill in the near future
