SGNA and AAMI provide the most widely adopted professional guidelines for endoscope reprocessing, including manual cleaning procedures, in the US.

Question 2

What does 'bioburden' refer to in the context of endoscope decontamination?

Accepted Answer

The total number of viable microorganisms on the endoscope before reprocessing

Answer

Bioburden is the quantitative measure of viable microorganisms present on or in the endoscope that must be reduced through proper cleaning and disinfection.

Question 3

What is the risk of inadequate rinsing after enzymatic cleaning of an endoscope?

Accepted Answer

Residual detergent can interfere with high-level disinfection and potentially cause patient harm

Answer

Enzymatic residue can neutralize disinfectants and cause mucosal injury in patients if it remains in the channels when the scope is next used.

Question 4

Which factor most significantly reduces the effectiveness of enzymatic cleaners?

Accepted Answer

Failure to follow the manufacturer's recommended contact time and temperature

Answer

Enzymatic cleaners require specific contact time and temperature conditions to function optimally; deviating from these parameters significantly reduces soil removal efficacy.

Question 5

What is the correct sequence of manual cleaning steps for a flexible endoscope?

Accepted Answer

Point-of-use pre-cleaning → leak test → enzymatic soak/brushing → thorough rinse

Answer

The correct sequence begins with point-of-use pre-cleaning, followed by leak testing, then enzymatic soaking and brushing, and finally thorough rinsing before high-level disinfection.
