AORN Aseptic Technique 4

Question 1

Which statement about environmental controls in the OR best supports aseptic technique?

Accepted Answer

Positive-pressure airflow in the OR directs air outward to prevent external contamination

Answer

ORs are maintained at positive pressure relative to corridors to push potentially contaminated air outward, reducing the risk of airborne contamination entering the sterile field.

Question 2

What is the purpose of performing a surgical hand antisepsis (scrub) before donning sterile gloves?

Accepted Answer

To reduce microbial counts on hands so that glove perforation poses less risk

Answer

Surgical hand antisepsis reduces the microbial burden so that if a glove is perforated, the risk of contaminating the surgical site is minimized.

Question 3

Which traffic pattern practice in the OR best supports aseptic technique during surgery?

Accepted Answer

Minimizing door openings to reduce airborne contamination

Answer

Frequent door openings disrupt positive-pressure airflow and increase the introduction of airborne particles, so traffic should be minimized during surgery.

Question 4

A surgeon accidentally contaminates their glove by touching their face shield. What is the priority action?

Accepted Answer

Change gloves immediately before re-entering the sterile field

Answer

A contaminated glove must be changed immediately to restore sterile barrier integrity before continued patient contact.

Question 5

When preparing for a case, the scrub nurse notes the sterilization indicator tape on a wrapped set has not changed color correctly. What should be done?

Accepted Answer

Return the set for re-sterilization and obtain a new sterile set

Answer

Incorrect indicator color change means sterilization cannot be confirmed; the set must not be used and should be returned for re-processing.
