Question 1

A rigid sterilization container's filter retention plate is cracked. What is the correct course of action?

Accepted Answer

Replace the container immediately and remove it from service

Answer

A cracked retention plate cannot reliably secure the filter, compromising the sterile barrier; the container must be taken out of service for repair or replacement.

Question 2

Which wrapping material is preferred for items to be sterilized using hydrogen peroxide gas plasma (VPHP)?

Accepted Answer

Non-woven polypropylene (spunbond) wrap

Answer

Cellulose-based materials (paper, muslin) absorb hydrogen peroxide and are incompatible with VPHP sterilization; non-woven polypropylene wraps are the correct choice.

Question 3

What is the function of a Bowie-Dick test when performed on a pre-vacuum steam sterilizer?

Accepted Answer

Verifies the sterilizer's ability to remove air and penetrate porous loads

Answer

The Bowie-Dick test detects air removal and steam penetration failures in pre-vacuum sterilizers, which is critical for ensuring sterilant contact with porous loads.

Question 4

Instruments with tungsten carbide inserts should be packaged in trays that include which of the following?

Accepted Answer

Silicone mats or foam inserts to prevent contact damage

Answer

Silicone or foam inserts protect delicate tungsten carbide inserts from impact damage during transport and sterilization cycles.

Question 5

Which of the following best describes the 'square fold' (envelope fold) wrapping method?

Accepted Answer

Each corner of the wrap is brought to the center sequentially, creating a neat envelope-style fold

Answer

The envelope or square fold involves folding opposing corners sequentially to the center, producing a neat triangular flap opening that supports aseptic presentation.
