CSFA Aseptic Technique and Sterilization 5

Question 1

Which condition is most likely to compromise the sterility of an event-related sterile package?

Accepted Answer

Physical damage, moisture exposure, or packaging compromise

Answer

Event-related sterility is maintained until the packaging is physically compromised by damage, moisture, or breach, not simply by time elapsed.

Question 2

During hydrogen peroxide plasma sterilization, which materials are incompatible with this process?

Accepted Answer

Cellulose-based materials such as paper or linen

Answer

Cellulose-based materials absorb hydrogen peroxide and interfere with plasma formation, making them incompatible with this sterilization method.

Question 3

What is the correct sequence for surgical hand antisepsis using a surgical hand scrub?

Accepted Answer

Scrub fingernails and subungual areas first, then hands, wrists, and forearms

Answer

Surgical hand antisepsis begins with subungual areas and nails (highest microbial load), then progresses distally to proximally through hands, wrists, and forearms.

Question 4

When applying sterile gloves using the closed-glove technique, the hands must remain:

Accepted Answer

Inside the cuffs of the gown throughout the entire gloving process

Answer

In the closed-glove technique, hands remain inside the gown cuffs until gloves are fully applied, preventing ungloved hands from contaminating the sterile gown exterior.

Question 5

Which factor most critically determines the efficacy of sterilization by steam autoclave?

Accepted Answer

Adequate contact of saturated steam with all surfaces at correct temperature and time

Answer

Steam sterilization efficacy depends on saturated steam making direct contact with all surfaces at the correct temperature for the required time.
