Read the first 7 Endoscope Repair and Maintenance Questions and Answers flashcards as text

  1. A flexible endoscope's biopsy port cover is found cracked after a procedure. The correct action is to:

    Answer: Replace the cover before the next reprocessing cycle

    A cracked biopsy port cover must be replaced immediately because it can harbor microorganisms and compromise the waterproof seal of the endoscope.

  2. Which component of a video endoscope is MOST susceptible to damage from contact with disinfectants that are not compatible with the scope?

    Answer: The CCD or CMOS image sensor

    Chemical incompatibility can damage the delicate CCD or CMOS image sensor and associated circuitry, leading to image degradation or total failure.

  3. The term 'scope creep' in the context of endoscope maintenance refers to:

    Answer: Accumulation of deferred repairs leading to increased breakdown rates

    In maintenance management, 'scope creep' refers to neglecting minor repairs that accumulate and result in more costly breakdowns over time.

  4. Which finding during a post-procedure visual inspection would indicate the endoscope requires immediate removal from service?

    Answer: Fluid visible inside the distal tip under the lens

    Fluid visible inside the distal tip indicates lens seal failure and internal contamination, requiring immediate removal from service and repair.

  5. What is the primary purpose of applying endoscope-compatible lubricant to the angulation mechanism?

    Answer: To reduce friction and prevent premature wear of internal components

    Approved lubricants reduce mechanical friction in the angulation controls, extending the life of wires, chains, and brake components.

  6. An endoscope fails a leak test only when the angulation controls are fully deflected. This pattern suggests:

    Answer: A pinhole defect in the bending section that opens under flexion

    A defect that is apparent only under full angulation indicates a small breach in the bending rubber that opens when the scope is maximally flexed.

  7. According to AAMI ST91, what information should be documented when a flexible endoscope is sent out for repair?

    Answer: Scope serial number, nature of damage, date sent, and reprocessing status before transport

    AAMI ST91 requires documenting the scope's serial number, damage description, date sent for repair, and confirmation that it was properly reprocessed before transport.
