Section 1: Aseptic Technique & Sterile Field (Questions 1–20)
1. Which of the following actions violates sterile technique
when opening a sterile package?
A) Opening the top flap away from the body
B) Opening the side flaps to the side
C) Reaching over the sterile field to open the final flap
D) Opening the package on a dry, clean surface
Answer: C
Rationale: Reaching over the sterile field contaminates it. The
final flap should be pulled toward the body, not reached over. All
other options are correct principles of sterile package opening.
2. What is the maximum allowable distance between the
sterile field and the circulating nurse's non-sterile body?
A) 6 inches
B) 12 inches
C) 18 inches
D) 24 inches
,Answer: B (12 inches)
Rationale: The sterile field must be maintained at least 12 inches
away from non-sterile areas, including the circulating nurse's
body, to prevent contamination.
3. A scrub person's sterile gown becomes contaminated on
the sleeve. What is the appropriate action?
A) Cover the area with a sterile towel
B) Change the gown immediately
C) Continue working but avoid touching that area
D) Apply an impervious sterile drape over the area
Answer: B
Rationale: Any contamination of a sterile gown requires
immediate changing. Covering the area does not restore sterility
and poses a risk to the patient.
4. Which part of the sterile gown is considered sterile?
A) The entire front from shoulders to waist
B) The sleeves from wrist to 2 inches above the elbow
C) The back of the gown
D) The neckline area
Answer: A
Rationale: The sterile area of the gown is the front from
shoulders to waist. The sleeves are sterile from 2 inches above the
elbow to the cuff. The back and neckline are considered non-
sterile.
,5. When performing surgical hand antisepsis, how long
should the scrub last when using an antimicrobial soap and
water?
A) 1–2 minutes
B) 2–4 minutes
C) 4–6 minutes
D) 6–8 minutes
Answer: C (4–6 minutes)
Rationale: AORN guidelines recommend a surgical hand scrub of
4–6 minutes when using antimicrobial soap and water to
effectively reduce microbial counts.
6. Which of the following is NOT an acceptable method of
sterilization for heat-sensitive instruments?
A) Ethylene oxide (EO) gas
B) Hydrogen peroxide gas plasma
C) Steam autoclave
D) Low-temperature sterilization with peracetic acid
Answer: C
Rationale: Steam autoclave uses high heat and moisture, which
can damage heat-sensitive instruments. The other methods are
low-temperature sterilization options appropriate for heat-
sensitive items.
7. What is the primary purpose of the flash sterilization cycle?
A) Routine sterilization of all instruments
B) Sterilization of instruments that cannot be processed
otherwise
, C) Emergency sterilization of a single, unwrapped item for
immediate use
D) Sterilization of implantable devices
Answer: C
Rationale: Flash sterilization is used for emergency sterilization of
a single, unwrapped item when time does not permit standard
processing. It should not be used for routine sterilization or
implants unless absolutely necessary.
8. A sterile field should be established as close as possible to
the time of use. What is the maximum recommended time a
sterile field can remain uncovered before use?
A) 15 minutes
B) 30 minutes
C) 1 hour
D) There is no specific time limit; it depends on air quality
Answer: C (1 hour)
Rationale: AORN guidelines recommend that an uncovered
sterile field should be used within 1 hour of setup to minimize the
risk of airborne contamination.
9. Which of the following is a correct principle of sterile
technique regarding sterile drapes?
A) Drapes should be shaken out to unfold them quickly
B) The top surface of the drape is considered sterile
C) Once placed, drapes should not be moved or repositioned
D) All of the above
