QUIZ 1: PERIOPERATIVE FUNDAMENTALS (50 Questions)
Section 1: Surgical Asepsis and Sterile Technique (12 Questions)
Q1: Which of the following principles of surgical asepsis is correct?
A. Sterile fields may be prepared in advance and covered until needed
B. The outer 1-inch margin of a sterile field is considered contaminated [CORRECT]
C. Sterile gloves are not required if hands are washed thoroughly
D. Talking is permitted over a sterile field without a mask
Correct Answer: B
Rationale: Per AORN guidelines, the outer 1-inch margin of a sterile field is considered
contaminated due to potential contact with non-sterile surfaces. Option A is incorrect—sterile
fields should be prepared as close to use time as possible and monitored. Option C is incorrect—
surgical hand antisepsis followed by sterile gown and gloves is mandatory for sterile team
members. Option D is incorrect—masks are required to prevent droplet contamination, and
talking should be minimized over sterile fields.
Cognitive Level: Recall
Q2: A surgical instrument is dropped on the floor during a procedure. Which of the following
actions should the surgical first assistant take?
A. Pick it up and continue using it
B. Ask the circulator for a replacement sterile instrument [CORRECT]
C. Rinse it with sterile water and continue
,2
D. Wipe it with a sterile towel and return it to the field
Correct Answer: B
Rationale: Any item falling below the sterile field is considered contaminated. The scrubbed
person maintains sterility and cannot retrieve dropped items. The circulator (non-sterile) retrieves
or replaces the item. Options A, C, and D violate surgical asepsis principles and increase risk of
surgical site infection.
Cognitive Level: Application
Q3: Which of the following is an acceptable method for sterilizing heat-sensitive instruments?
A. Steam autoclave
B. Ethylene oxide gas [CORRECT]
C. Boiling water
D. Alcohol soak
Correct Answer: B
Rationale: Ethylene oxide (ETO) gas sterilization is suitable for heat-sensitive instruments
(plastics, electronics, endoscopes). Steam autoclave (A) uses heat and moisture inappropriate for
heat-sensitive items. Boiling water (C) achieves disinfection, not sterilization (does not kill
spores). Alcohol soak (D) is disinfection, not sterilization.
Cognitive Level: Recall
Q4: During a surgical procedure, the scrubbed surgical first assistant needs to change a glove
that has a tear. Which of the following actions is correct?
A. Change both gloves using the closed gloving technique
B. Change only the torn glove using the open gloving technique [CORRECT]
C. Continue the procedure and change gloves at the end
D. Have the circulator apply a sterile glove over the torn glove
Correct Answer: B
Rationale: When changing a single glove during a procedure, the open gloving technique is
used. The sterile team member maintains sterility of the gown while the circulator assists with
,3
open gloving. Option A is unnecessarily time-consuming. Option C violates aseptic principles.
Option D creates contamination risk and compromised tactile sensitivity.
Cognitive Level: Application
Q5: Which of the following is the appropriate action when the surgical first assistant's gown
becomes contaminated during surgery?
A. Cover the contaminated area with a sterile towel and continue
B. Change the gown immediately [CORRECT]
C. Have the circulator spray the area with antimicrobial solution
D. Ignore the contamination if the sterile gloves are intact
Correct Answer: B
Rationale: Contaminated gowns must be changed immediately to maintain sterile field integrity.
Options A, C, and D do not eliminate contamination and increase surgical site infection risk. The
surgical first assistant should step away from the sterile field, remove the contaminated gown,
and regown using appropriate technique.
Cognitive Level: Application
Q6: When performing a surgical hand scrub, the minimum recommended duration is:
A. 2 minutes
B. 3-5 minutes [CORRECT]
C. 30 seconds
D. 10 minutes
Correct Answer: B
Rationale: Per AORN and CDC guidelines, surgical hand antisepsis requires 3-5 minutes of
scrubbing with antimicrobial agent (or per manufacturer instructions). Option A may be
insufficient for adequate microbial reduction. Option C is inadequate. Option D is excessive and
may damage skin integrity.
Cognitive Level: Recall
Q7: Which of the following statements about surgical masks is correct?
, 4
A. Masks can be reused if they appear clean
B. Masks should be changed between procedures or when wet [CORRECT]
C. Masks are only required during the incision phase
D. Masks with vents are preferred for comfort
Correct Answer: B
Rationale: Surgical masks must be changed between procedures and whenever they become wet
or contaminated. Option A is incorrect—masks are single-use. Option C is incorrect—masks are
required throughout the procedure and in the OR suite. Option D is incorrect—vented masks do
not protect the sterile field from the wearer's exhaled breath.
Cognitive Level: Recall
Q8: The surgical first assistant notices a hole in the sterile drape covering the Mayo stand.
Which of the following actions is appropriate?
A. Cover the hole with a sterile towel
B. Replace the drape or relocate instruments to a sterile area [CORRECT]
C. Continue using the stand if the hole is small
D. Ignore the hole if no one touches it
Correct Answer: B
Rationale: Any breach in sterile barriers requires immediate correction. The drape should be
replaced or instruments moved to a completely sterile area. Options A, C, and D compromise
sterile technique and increase infection risk.
Cognitive Level: Application
Q9: Which of the following is an acceptable method for donning sterile gloves?
A. Touching the outer surface of the gloves with bare hands
B. Using the closed gloving technique after donning a sterile gown [CORRECT]
C. Powdered gloves are preferred for easier donning
D. Gloves can be pulled on without maintaining cuff sterility
Correct Answer: B
