Question 1

What is the term for the process of verifying that an AER consistently achieves the required log reduction of test organisms?

Accepted Answer

Validation

Answer

Validation is the documented process confirming that an AER cycle reliably delivers the intended level of microbial kill under defined conditions.

Question 2

Which scenario would require immediate removal of an AER from service?

Accepted Answer

Disinfectant concentration is confirmed below the minimum effective concentration (MEC)

Answer

Disinfectant below the MEC cannot achieve high-level disinfection, making the machine unsafe to use until the solution is replaced and the MEC is re-confirmed.

Question 3

What is the purpose of running a daily function test or cycle check on an AER?

Accepted Answer

To confirm the machine's mechanical and chemical parameters are within specifications before patient care use

Answer

Daily function tests verify that AER parameters such as temperature, exposure time, and chemical concentration meet specifications before scopes used on patients are processed.

Question 4

Which microorganism is most associated with outbreaks linked to inadequate AER water quality?

Accepted Answer

Pseudomonas aeruginosa

Answer

Pseudomonas aeruginosa is a waterborne organism that can colonize AER water systems and recontaminate scopes during the rinse phase if water quality is inadequate.

Question 5

How should AER channel adapters and connectors be maintained between uses?

Accepted Answer

Stored dry after being cleaned and disinfected per the AER manufacturer's IFU

Answer

Connectors must be cleaned, disinfected, and stored dry between uses as specified by the AER manufacturer to prevent biofilm formation and cross-contamination.
