Question 1

Which of the following is a sign of light guide bundle degradation in a flexible endoscope?

Accepted Answer

Dark spots or reduced illumination during procedures

Answer

Broken fibers in the light guide bundle appear as dark spots and reduce overall illumination delivered to the distal tip.

Question 2

When should a reprocessor perform a pre-cleaning inspection of an endoscope?

Accepted Answer

Immediately after every patient use, before reprocessing begins

Answer

Post-procedure, pre-cleaning inspection is required after every use to identify damage before reprocessing chemicals or processes can obscure or worsen it.

Question 3

What does a 'positive' result on an endoscope leak test indicate?

Accepted Answer

The scope has a leak and must be removed from service

Answer

A positive leak test result means fluid or air is escaping from an unintended location, indicating a breach requiring repair before reprocessing.

Question 4

Which component seals the endoscope's electrical connections from fluid ingress during immersion?

Accepted Answer

Water-resistant (waterproof) cap

Answer

The water-resistant cap is placed over the video connector during reprocessing to protect internal electrical components from fluid damage.

Question 5

A colonoscope consistently requires repair to the same location on the insertion tube. This pattern MOST likely indicates:

Accepted Answer

A procedural or handling technique issue by clinical staff

Answer

Recurring damage at the same site suggests a consistent handling problem, such as improper technique during insertion, removal, or transport.
