During a post-reprocessing inspection, an endoscope's control body shows evidence of fluid ingress (fogging inside the video chip window). This indicates:
Answer: A failed leak test that was not caught — remove from service immediately
Fogging or moisture inside the video chip window means fluid entered the scope body, indicating an undetected breach that requires immediate removal from service and repair.
Which of the following describes a 'red-flag' finding that should be documented on a scope tracking log even if the scope passes inspection?
Answer: A transient pressure dip during leak testing that self-corrected
A transient pressure dip, even if recovered, may indicate an intermittent defect and must be documented so the scope's condition can be trended over time.
Which endoscope component is most prone to damage from improper transport and should receive focused inspection?
Answer: Distal tip and bending section
The distal tip and bending section are most vulnerable to impact and bending damage during transport and receive the most focused inspection after return from the procedure.
When a technician applies the leak tester and sees an immediate, rapid drop in pressure before the scope is submerged, the correct interpretation is:
Answer: There is a large breach in the scope that is detectable without submersion
A rapid, immediate pressure drop before submersion indicates a large defect that cannot hold pressurization, confirming the scope must be removed from service.
Inspection of the endoscope's umbilical cord reveals a kink with visible discoloration at the bend site. The recommended action is:
Answer: Remove from service for biomedical evaluation of potential internal damage
A kink with discoloration indicates mechanical stress and possible internal conductor or channel damage, requiring biomedical evaluation before the scope is returned to service.
A scope returned from an ENT procedure has visible debris in the instrument channel that cannot be removed by flushing alone. What is the next step?
Answer: Use a channel cleaning brush of the appropriate size to mechanically remove the debris
Mechanical brushing with an appropriately sized brush is required to physically remove debris that flushing alone cannot dislodge, ensuring adequate cleaning before disinfection.
When is it appropriate to return a scope to service after a positive leak test?
Answer: Never — a positive leak test always requires repair before return to service
A positive leak test always means the scope must be sent for repair before it can be returned to service, regardless of the perceived severity of the breach.
