7. A patient undergoing surgery is positioned in the lithotomy position. Which nerve
is most at risk for injury in this position?
• A) Sciatic nerve
• B) Femoral nerve
• C) Common peroneal nerve
• D) Brachial plexus
Answer: C
Rationale: In the lithotomy position, the common peroneal nerve is at risk for injury due
to compression against the leg stirrups. This can result in foot drop. The brachial plexus
can be injured in the lateral position; the sciatic and femoral nerves can be injured in
various positions. Proper positioning and padding are essential to prevent nerve
injuries.
8. Which of the following is a correct step in the surgical hand scrub procedure?
, Page 4 of 82

Answer: B
Rationale: The surgical conscience is the professional obligation to adhere to sterile

perioperative nursing and patient safety. The CNOR exam tests understanding of this
principle because it distinguishes hospital practice from AORN standards.
10. A patient is positioned in the prone position for a spine procedure. Which
assessment is most critical to prevent complications in this position?
• A) Checking the blood pressure in the lower extremities
• B) Ensuring the patient's eyes are free from pressure
• C) Monitoring the heart rate
• D) Checking the temperature
Answer: B
Rationale: In the prone position, ensuring the patient's eyes are free from pressure is
critical to prevent corneal abrasions or retinal ischemia . Other important
considerations include proper padding of pressure points and maintaining the head in a
neutral position to prevent cervical spine injury.
