CST OR Setup & Room Turnover 3

Question 1

Which of the following is the CORRECT sequence for donning sterile attire before a case?

Accepted Answer

Gown, then gloves

Answer

The gown is donned first because the hands must remain uncontaminated to open and position the gown; gloves are then applied over the gown cuffs.

Question 2

A case cart delivered to the OR contains a package with an expired sterilization date. The scrub tech should:

Accepted Answer

Return the item, obtain a replacement, and notify the charge nurse

Answer

Expired sterilization dating means sterility cannot be guaranteed; the item must be replaced and the incident reported.

Question 3

The recommended minimum air exchanges per hour in a standard OR to maintain air quality is:

Accepted Answer

15 exchanges per hour

Answer

AORN and ASHRAE standards recommend a minimum of 15 air exchanges per hour in the OR, with at least 3 being fresh outside air.

Question 4

When creating a sterile field, the scrub technician should open the back table drape by:

Accepted Answer

Cuffing the drape over gloved hands and unfolding away from the body

Answer

Cuffing the drape over gloved hands protects the sterility of the gloves while the drape is unfolded away from the body to prevent contamination.

Question 5

Ideally, the back table should be set up how far in advance of the surgical incision?

Accepted Answer

As close to the start of the case as practical; no more than 4 hours before the first incision

Answer

AORN recommends setting up the sterile field as close to the time of use as possible, with 4 hours as an accepted outer limit in most facilities.
