CNOR Certification MCQ 4

Question 1

Flash sterilization (immediate-use steam sterilization, IUSS) should be used:

Accepted Answer

Only when there is no time to perform standard sterilization and documented need exists

Question 2

A patient with a known penicillin allergy is to receive surgical antibiotic prophylaxis. The perioperative nurse should anticipate which alternative?

Accepted Answer

Clindamycin or vancomycin as alternatives based on the procedure and allergy severity

Answer

Clindamycin or vancomycin are commonly used alternatives for patients with penicillin allergy undergoing procedures requiring beta-lactam prophylaxis.

Question 3

Which action BEST reduces the risk of surgical site infection (SSI) related to hair removal?

Accepted Answer

Clipping hair at the operative site immediately before the procedure if removal is necessary

Answer

Clipping immediately before surgery is preferred over shaving because razors create micro-abrasions that harbor bacteria and increase SSI risk.

Question 4

During the postoperative count, the sponge count is incorrect. The IMMEDIATE action is to:

Accepted Answer

Notify the surgeon immediately, search the field and room, and obtain an intraoperative X-ray if the sponge is not found

Answer

An incorrect count mandates immediate surgeon notification, systematic search, and intraoperative radiograph before wound closure to prevent RSI.

Question 5

Which position places the patient at highest risk for air embolism?

Accepted Answer

Sitting (beach chair) craniotomy position

Answer

In the sitting position, the operative site is above the level of the heart, creating negative venous pressure that allows air entrainment into open venous sinuses.
