CBSPD Endoscope Reprocessing and Flexible Scope Care

Question 1

What is the minimum level of disinfection required for flexible endoscopes used in semi-critical procedures?

Accepted Answer

High-level disinfection

Answer

Semi-critical devices like flexible endoscopes require high-level disinfection (HLD) to eliminate all microorganisms except high levels of bacterial spores.

Question 2

Which step must be performed immediately after a flexible endoscope is removed from the patient?

Accepted Answer

Point-of-use wiping and flushing of channels

Answer

Point-of-use treatment — wiping the exterior and flushing channels with water or enzymatic solution — must occur immediately to prevent biofilm formation.

Question 3

What is the purpose of leak testing a flexible endoscope?

Accepted Answer

To detect internal damage that could allow fluid ingress

Answer

Leak testing identifies breaches in the endoscope's internal structure that could allow fluids to enter and damage components or harbor pathogens.

Question 4

Which chemical is most commonly used as a high-level disinfectant for flexible endoscopes?

Accepted Answer

Peracetic acid or glutaraldehyde

Answer

Glutaraldehyde and peracetic acid-based products (e.g., Cidex, Steris System 1) are the most commonly used high-level disinfectants for flexible endoscopes.

Question 5

After high-level disinfection, how should flexible endoscopes be rinsed?

Accepted Answer

With sterile water or filtered water

Answer

Sterile or filtered water must be used for the final rinse to prevent recontamination from microorganisms present in tap water.
