CER Endoscope Repair and Maintenance 5

Question 1

Which document provides the manufacturer's specific instructions for reprocessing and maintenance of a particular endoscope model?

Accepted Answer

Instructions for Use (IFU)

Answer

The manufacturer's Instructions for Use (IFU) provide model-specific guidance on cleaning, disinfection, and maintenance that must be followed.

Question 2

What is the primary risk of reprocessing an endoscope with a known internal leak?

Accepted Answer

Fluid entering internal components, causing corrosion and cross-contamination risk

Answer

Internal leaks allow reprocessing chemicals and patient material to enter the scope's body, causing corrosion of mechanical parts and potential cross-contamination.

Question 3

Which type of endoscope damage is MOST likely to result in cross-contamination between patients?

Accepted Answer

Breach in the biopsy channel allowing fluid to bypass reprocessing

Answer

A breach in the biopsy channel can harbor biological material that is not fully reached by disinfectants, creating a cross-contamination pathway.

Question 4

After transport from the procedure room, endoscopes should be point-of-use pre-cleaned by:

Accepted Answer

Wiping the exterior and flushing channels with enzymatic solution before transport to reprocessing

Answer

Point-of-use pre-cleaning with an enzymatic solution prevents bioburden from drying and becoming more difficult to remove before formal reprocessing.

Question 5

What is the consequence of using a cleaning brush with a diameter too small for the endoscope channel?

Accepted Answer

Inadequate mechanical action, leaving debris on channel walls

Answer

A brush that is too small will not contact channel walls adequately, leaving biofilm and debris that can compromise disinfection efficacy.
