UPDATE. JUST RELEASED
1. When performing a surgical scrub, the scrub person should always follow which principle
regarding the movement of their hands?
A. From elbows to fingertips
B. From fingertips to 2 inches above the elbow
C. From fingertips to the wrist
D. In a back-and-forth scrubbing motion
Answer: B
Conceptual Explanation: AORN guidelines state that surgical hand antisepsis should
follow a specific progression from the cleanest area (fingertips) to the least clean area
(elbows) to prevent contamination.
,2. According to AORN guidelines, what is the recommended humidity range for the operating
room?
A. 10% to 50%
B. 30% to 70%
C. 20% to 60%
D. 40% to 80%
Answer: C
Conceptual Explanation: AORN recommends a relative humidity between 20% and 60%
to inhibit microbial growth and prevent static electricity, which can be a fire hazard.
3. During a surgical procedure, the circulator notices a hole in the sterile drape. What is the
most appropriate action?
A. Cover the hole with a sterile towel
B. Ignore it if the hole is far from the incision
C. Request that the entire field be re-draped
D. Apply a piece of adhesive tape over the hole
Answer: C
Conceptual Explanation: Integrity of the sterile field is paramount. If a drape is
compromised, the standard protocol is to replace the contaminated items to maintain
aseptic conditions.
, 4. Which of the following is the most critical symptom of Malignant Hyperthermia (MH) that
usually appears first?
A. Unexplained increase in end-tidal CO2
B. Rapid rise in body temperature
C. Muscle rigidity
D. Tachycardia
Answer: A
Conceptual Explanation: While temperature rise is a sign of MH, an unexplained increase
in end-tidal carbon dioxide (EtCO2) is typically the earliest and most consistent sign of an
MH crisis.
5. When placing the electrosurgical return electrode (bovie pad), which site is most
appropriate?
A. Over a bony prominence
B. Directly over a metal implant
C. Over a tattooed area
D. As close to the surgical site as possible over a large muscle mass
Answer: D
