IAHCSMM Sterilization Methods & Monitoring 2

Question 1

What does a Class 5 integrating indicator measure?

Accepted Answer

All critical variables: time, temperature, and steam quality

Answer

Class 5 integrating indicators respond to all critical parameters (time, temperature, and steam) and are designed to correlate with the performance of BIs.

Question 2

Hydrogen peroxide gas plasma sterilization is best suited for:

Accepted Answer

Heat-sensitive devices with compatible materials (short lumens, non-cellulose)

Answer

H2O2 gas plasma works well for heat-sensitive items but is incompatible with cellulose (paper, linen) and very long or narrow lumens.

Question 3

What is the purpose of load control numbers (lot numbers) on sterilized packages?

Accepted Answer

To enable traceability and facilitate recall if a sterilization failure is identified

Answer

Load control numbers link each package to a specific sterilization cycle, enabling rapid identification and recall of items if a cycle fails.

Question 4

What is 'parametric release' in sterilization?

Accepted Answer

Releasing sterilized loads based on documented physical parameters meeting all cycle requirements

Answer

Parametric release allows items to be released based on verified physical cycle data (temperature, time, pressure) meeting all specifications without waiting for BI incubation.

Question 5

What sterilization method uses peracetic acid and is commonly used for heat-sensitive endoscopes?

Accepted Answer

STERIS System 1E (peracetic acid immersion)

Answer

The STERIS System 1E uses liquid peracetic acid for rapid, low-temperature sterilization of heat-sensitive immersible devices at the point of use.
