  1. Which type of damage is most commonly associated with improper coiling of flexible endoscopes during transport?

    Answer: Light guide fiber fracture

    Tight or improper coiling stresses the light guide bundle, causing individual fibers to fracture and resulting in black spots in the image.

  2. When inspecting an endoscope's insertion tube, a visible kink indicates:

    Answer: Damage requiring repair before reuse

    A kinked insertion tube indicates structural damage to the braid or coil layers that compromises function and must be repaired before clinical use.

  3. What is the recommended minimum bend radius specification used when storing flexible endoscopes in a drying cabinet?

    Answer: As specified by the manufacturer's IFU

    Manufacturers specify minimum bend radii in their IFUs to prevent internal component stress during storage; these values vary by model.

  4. A technician notices the up/down angulation control is stiff but the left/right control moves freely. The most likely cause is:

    Answer: A broken angulation chain on the up/down axis

    Stiffness in one angulation axis while the other moves freely typically indicates a broken or stretched angulation chain or wire in that specific axis.

  5. Which preventive maintenance task should be performed on endoscope valves and caps after every use?

    Answer: Inspection for cracks, tears, and O-ring integrity

    Valves and caps must be inspected after each use for cracks, tears, and O-ring integrity to ensure leak-tight function during reprocessing and use.

  6. What does a positive leak test result (pressure drop detected) indicate?

    Answer: There is a breach in the endoscope's waterproof integrity

    A pressure drop during leak testing indicates that the endoscope's protective sheath or internal seals have been breached, allowing fluid ingress.

  7. When should the air/water and suction channel brushes be replaced during endoscope reprocessing?

    Answer: After every use per SGNA guidelines

    SGNA guidelines recommend single-use channel brushes or, if reusable, meticulous reprocessing after every use to prevent cross-contamination.
