Question 1
A nurse is preparing a sterile field. Which of the following actions contaminated the sterile field?
(Select All That Apply)
A. A cotton ball dampened with sterile normal saline is placed on the field.
B. A contaminated instrument touches the outer edge of the sterile field.
C. A sterile instrument is dropped onto the near side of the sterile field.
D. The nurse turns to address the client's question concerning the procedure.
E. The procedure is postponed for 30 minutes to accommodate the client.
F. A liquid is poured into a sterile container from a distance of 25 cm.
CORRECT ANSWER
A, D, E, F. A cotton ball (porous, cannot be sterile), turning away (turns back to field),
postponement (exposed to air), pouring from too high (splashes).
RATIONALE
• Cotton balls cannot be sterilized; they wick bacteria.
• Turning your back to a sterile field contaminates it because you cannot see if something touched it.
• Extended exposure to air contaminates; pour from 4-6 inches (10-15 cm), not 25 cm.
, Question 2
A nurse should identify that which of the following is the goal of surgical asepsis?
A. To create and maintain a micro-organism-free environment.
B. To kill all micro-organisms on all instruments involved in a procedure.
C. To reduce the presence of pathogenic organisms in the environment.
D. To minimize exposure to the client's blood during an invasive procedure.
CORRECT ANSWER
A. To create and maintain a micro-organism-free environment.
RATIONALE
• Surgical asepsis (sterile technique) eliminates ALL microorganisms, including spores.
• Medical asepsis (clean technique) reduces the number of pathogens.
• Surgical asepsis is required for invasive procedures, wound care, and catheter insertion.
Question 3
When donning sterile gloves using the open-gloving method, which instruction should the nurse give
regarding hand placement?
A. "Ask another team member to assist with donning gloves."
B. "Choose a pair of gloves at least one size smaller than usual."
C. "Grasp only the underside of the cuff with your ungloved hand."
D. "Grasp only the inside of the glove with your ungloved hand."
CORRECT ANSWER
D. "Grasp only the inside of the glove with your ungloved hand."
RATIONALE
• The inside of the glove (cuff edge) will contact the skin and is not considered sterile.
• The outside of the glove is sterile and should only be touched by another sterile glove.
• This prevents contamination of the sterile outer surface.
