Which component of a flexible endoscope is most commonly damaged by improper angulation during use?
Answer: Angulation wires
Angulation wires are highly susceptible to kinking or breaking when the endoscope is bent beyond its designed range of motion.
A reprocessor notices the endoscope tip will not deflect fully in one direction. What is the MOST likely cause?
Answer: Broken or stretched angulation wire
Broken or stretched angulation wires are the primary cause of limited or asymmetric tip deflection.
What type of damage does prolonged exposure to aldehydes cause to endoscope insertion tube sheaths?
Answer: Softening and swelling of the polymer sheath
Extended aldehyde exposure can degrade polymer materials, causing swelling and loss of structural integrity in the insertion tube sheath.
When performing a leak test, steady bubbling from the biopsy channel opening most likely indicates:
Answer: A perforation in the biopsy channel
Steady bubbling from the biopsy port during leak testing indicates a breach in the biopsy channel wall.
Which maintenance task should be performed on endoscope light guide connectors to prevent damage?
Answer: Inspecting and cleaning the optical surfaces with approved wipes
Light guide connector optical surfaces should be regularly inspected and cleaned with lint-free, approved wipes to maintain image quality and prevent damage.
An endoscope's biopsy channel shows resistance when passing a cleaning brush. What should the reprocessor do FIRST?
Answer: Remove the brush and inspect the channel for damage
Forcing a brush through resistance can cause further damage; the channel should be inspected immediately to identify the obstruction or damage.
What is the purpose of the endoscope control body's rubber exterior during transport?
Answer: Protects internal components from impact and moisture ingress
The rubber exterior of the control body protects delicate internal mechanisms from physical impact and helps prevent moisture from entering during handling.
