Question 1

A chemical indicator (CI) placed inside a wrapped instrument set serves what primary function?

Accepted Answer

Confirms the package was exposed to sterilization conditions

Answer

Internal CIs confirm that sterilization conditions (such as steam, temperature, and time) penetrated the packaging and reached the instruments inside.

Question 2

The Bowie-Dick test is used to detect:

Accepted Answer

Air removal and steam penetration issues in pre-vacuum sterilizers

Answer

The Bowie-Dick test verifies that the pre-vacuum sterilizer is effectively removing air and allowing steam to penetrate the load uniformly.

Question 3

Point-of-use treatment of contaminated instruments before transport to the decontamination area should include:

Accepted Answer

Removing gross soil and keeping instruments moist to prevent drying

Answer

Removing gross soil and keeping instruments moist prevents bioburden from drying and hardening, which makes subsequent cleaning much more difficult.

Question 4

Which personal protective equipment (PPE) is required when working in the decontamination area?

Accepted Answer

Utility gloves, face shield, fluid-resistant gown, and shoe covers

Answer

The decontamination area requires full barrier PPE including utility gloves, face shield, fluid-resistant gown, and shoe covers to protect against blood and body fluid exposure.

Question 5

What does the term 'bioburden' refer to in instrument processing?

Accepted Answer

The number and type of viable microorganisms on an unsterilized item

Answer

Bioburden refers to the population of viable microorganisms present on an item before sterilization, which must be minimized through effective cleaning.
