Question 1

What is the correct term for the process of reducing microbial contamination to a safe level without achieving sterility?

Accepted Answer

Disinfection

Answer

Disinfection reduces the number of viable microorganisms to a level considered safe for handling but does not necessarily eliminate all spores.

Question 2

Which ANSI/AAMI standard governs the comprehensive reprocessing of reusable medical devices?

Accepted Answer

ANSI/AAMI ST79

Answer

ANSI/AAMI ST79 is the comprehensive guide to steam sterilization and sterility assurance in healthcare facilities and covers all aspects of device reprocessing.

Question 3

A flash sterilization cycle (immediate-use steam sterilization) at 132°C in a pre-vacuum sterilizer requires a minimum exposure time of:

Accepted Answer

4 minutes

Answer

AAMI ST79 specifies a minimum of 4 minutes at 132°C for immediate-use steam sterilization (flash sterilization) in a pre-vacuum sterilizer with lumened devices.

Question 4

What does the term 'SAL 10⁻⁶' mean in the context of sterilization?

Accepted Answer

There is a 1 in 1,000,000 chance of a viable organism on a device

Answer

A Sterility Assurance Level of 10⁻⁶ means there is a 1 in 1,000,000 probability that a viable microorganism remains on a sterilized item.

Question 5

Which agent is classified as a high-level disinfectant capable of achieving sterilization with extended exposure time?

Accepted Answer

Hydrogen peroxide 7.5%

Answer

Hydrogen peroxide 7.5% is an EPA-registered sterilant/disinfectant that achieves high-level disinfection in 30 minutes and sterilization with extended (6-hour) exposure.
