CER Endoscope Reprocessing Fundamentals Questions and Answers 5

Question 1

What is the typical recommended maximum reuse period (in days) for a single-use enzymatic detergent solution?

Accepted Answer

Single-use only; must be discarded after each scope cleaning

Answer

Enzymatic detergent solutions are single-use and must be discarded after each endoscope cleaning cycle to prevent cross-contamination and enzyme depletion.

Question 2

Which type of brush is required when mechanically cleaning the channels of a flexible endoscope?

Accepted Answer

A channel-specific brush that fits the channel diameter snugly

Answer

Brushes must be sized to fit the channel diameter snugly to ensure full contact with channel walls, and must be long enough to pass completely through the channel.

Question 3

In an automated endoscope reprocessor (AER), what is the function of the self-disinfection cycle?

Accepted Answer

To decontaminate the machine's internal fluid pathways between uses

Answer

The AER self-disinfection cycle runs HLD or another disinfectant through the machine's own internal tubing and channels to prevent the machine itself from becoming a source of contamination.

Question 4

What personal protective equipment (PPE) is required as a minimum when manually cleaning contaminated endoscopes?

Accepted Answer

Gloves, fluid-resistant gown, face shield or mask and eye protection

Answer

OSHA and SGNA guidelines require gloves, a fluid-resistant gown, and face/eye protection to protect reprocessing staff from splashes of blood, body fluids, and chemical disinfectants.

Question 5

What is the significance of the 'reuse life' stated on a high-level disinfectant product label?

Accepted Answer

The maximum number of days the activated solution can be used before it must be discarded regardless of MEC

Answer

The reuse life is the manufacturer-validated maximum number of days an activated HLD solution may be used; it must be discarded after this period even if MEC testing still shows adequate concentration.
