Which of the following is a sign of light guide bundle degradation in a flexible endoscope?
Answer: Dark spots or reduced illumination during procedures
Broken fibers in the light guide bundle appear as dark spots and reduce overall illumination delivered to the distal tip.
When should a reprocessor perform a pre-cleaning inspection of an endoscope?
Answer: Immediately after every patient use, before reprocessing begins
Post-procedure, pre-cleaning inspection is required after every use to identify damage before reprocessing chemicals or processes can obscure or worsen it.
What does a 'positive' result on an endoscope leak test indicate?
Answer: The scope has a leak and must be removed from service
A positive leak test result means fluid or air is escaping from an unintended location, indicating a breach requiring repair before reprocessing.
Which component seals the endoscope's electrical connections from fluid ingress during immersion?
Answer: Water-resistant (waterproof) cap
The water-resistant cap is placed over the video connector during reprocessing to protect internal electrical components from fluid damage.
A colonoscope consistently requires repair to the same location on the insertion tube. This pattern MOST likely indicates:
Answer: A procedural or handling technique issue by clinical staff
Recurring damage at the same site suggests a consistent handling problem, such as improper technique during insertion, removal, or transport.
What is the recommended method for drying endoscope channels prior to storage?
Answer: Flushing with 70–90% isopropyl alcohol followed by forced air
Flushing channels with 70–90% isopropyl alcohol followed by forced air purging promotes rapid drying and prevents microbial growth during storage.
Why should endoscope accessories such as biopsy forceps be inspected before each use?
Answer: To identify sharp edges, cracks, or defects that could damage internal channels
Defective accessories with burrs or sharp edges can lacerate the biopsy channel liner, requiring costly endoscope repair.
