Question 1

When validating an AER after installation, which parameter must be confirmed to meet manufacturer specifications?

Accepted Answer

Disinfectant contact time and concentration

Answer

AER validation requires confirming that disinfectant contact time and concentration meet manufacturer specifications to ensure effective high-level disinfection.

Question 2

An AER cycle aborts mid-process due to a pressure fault. What is the FIRST action the reprocessing technician should take?

Accepted Answer

Remove the endoscope and manually complete high-level disinfection

Answer

When an AER cycle aborts, the endoscope should be removed and manually high-level disinfected to ensure it is safe before patient use.

Question 3

Which water quality standard is most critical for the final rinse phase of an AER cycle?

Accepted Answer

Sterile water or water meeting AAMI ST108 standards

Answer

AAMI ST108 establishes water quality standards, and the final rinse in an AER must use appropriately treated water to prevent recontamination of the endoscope.

Question 4

How often should AER filters (e.g., HEPA or water filters) typically be changed according to best practice?

Accepted Answer

According to the manufacturer's instructions for use

Answer

Filter replacement intervals must follow the AER manufacturer's instructions for use (IFU), as intervals vary by design and water quality.

Question 5

A biological indicator (BI) test of an AER shows growth after the cycle. What does this indicate?

Accepted Answer

The AER cycle may have failed to achieve adequate disinfection

Answer

Growth in a BI after an AER cycle indicates the process may not have achieved the required level of microbial kill, necessitating investigation and remediation.
