AORN PERIOP 101 FINAL EXAM
PRACTICE QUESTIONS AND ANSWERS
WITH VERIFIED SOLUTIONS 2026/2027
UPDATE. JUST RELEASED
1. Which of the following medications is the primary treatment for Malignant Hyperthermia
(MH)?
A. Succinylcholine
B. Dantrolene Sodium
C. Atropine
D. Epinephrine
Answer: B
Conceptual Explanation: Dantrolene is the only specific treatment for Malignant
Hyperthermia as it inhibits calcium release from the sarcoplasmic reticulum.
2. A surgical procedure involving the biliary tract with a minor break in technique is classified
as which wound category?
A. Class I: Clean
B. Class III: Contaminated
C. Class II: Clean-Contaminated
,D. Class IV: Dirty-Infected
Answer: C
Conceptual Explanation: Class II Clean-Contaminated wounds are those where the
respiratory, alimentary, genital, or urinary tracts are entered under controlled conditions
without unusual contamination.
3. What is the specific purpose of the Bowie-Dick test in a prevacuum steam sterilizer?
A. To detect air leaks and inadequate air removal
B. To ensure biological spores have been killed
C. To verify the chemical concentration of the steam
D. To check the temperature at the center of the load
Answer: A
Conceptual Explanation: The Bowie-Dick test is a daily air removal test to ensure that the
vacuum system is functioning properly to remove air from the chamber.
4. In the lithotomy position, pressure on the lateral aspect of the knee can cause injury to
which nerve?
A. Femoral nerve
B. Common peroneal nerve
C. Sciatic nerve
D. Obturator nerve
, Answer: B
Conceptual Explanation: The common peroneal nerve is susceptible to compression
against the stirrups in the lithotomy position, which can lead to foot drop.
5. Where should the electrosurgical unit (ESU) dispersive electrode (grounding pad) be ideally
placed?
A. Over a bony prominence
B. Near a large, well-perfused muscle mass
C. On a limb with a metal prosthesis
D. Directly over the surgical incision site
Answer: B
Conceptual Explanation: Muscle mass provides low impedance for the return current;
bony prominences and metal implants increase the risk of burns.
6. AORN standards recommend maintaining which type of air pressure in the restricted areas
of the OR suite?
A. Negative pressure
B. Fluctuating pressure
C. Atmospheric pressure
D. Positive pressure
Answer: D
