Why must all removable components such as valves and caps be removed before inspection and leak testing?
Answer: To allow thorough visual inspection and ensure accurate pressure readings
Removing valves and caps allows full visual access to ports and channels and ensures the leak test accurately reflects the scope body's integrity rather than masked by sealed components.
A duodenoscope elevator mechanism is stiff and does not move freely during functional inspection. This finding suggests:
Answer: Possible debris accumulation or mechanical damage requiring repair evaluation
A stiff elevator mechanism may indicate residual soil or mechanical damage; the duodenoscope's elevator channel is a known contamination risk and requires thorough evaluation.
Which action confirms that a scope's air/water channel is fully patent after reprocessing?
Answer: Visual confirmation of water flowing from the distal tip nozzle
Visually confirming that water flows freely from the distal nozzle when the air/water channel is flushed confirms the channel is patent.
When using a pressure manometer during leak testing, the pressure gauge should be read after:
Answer: Pressurizing to the specified range and stabilizing for 30 seconds, then submerging
Pressure must be allowed to stabilize before submerging so the baseline is established, then any subsequent drop indicates a leak.
An endoscope returned to the reprocessing area has a bend in the insertion tube that will not relax. The most likely cause is:
Answer: Coiling the scope too tightly beyond the minimum bend radius during use or transport
Coiling or bending the scope beyond its minimum bend radius can permanently kink internal components, particularly angulation wires and light guide fibers.
The correct sequence for visual and functional inspection of an endoscope AFTER bedside pre-cleaning is:
Answer: Transport to reprocessing → visual inspection → leak test → functional check
After bedside pre-cleaning, the scope is transported to the reprocessing room where thorough visual inspection, leak testing, and functional checks are performed before cleaning.
What is the significance of checking the light guide bundle for broken fibers during inspection?
Answer: Dark spots in the illumination field reduce visibility and may impair procedural safety
Each broken fiber creates a dark spot in the illumination field; sufficient fiber loss significantly degrades image quality and may compromise clinical visualization.
