Read the first 7 Endoscope Repair and Maintenance Questions and Answers flashcards as text
Which type of endoscope damage is typically classified as 'functional' rather than 'cosmetic'?
Answer: Impaired suction due to a partial channel obstruction
Impaired suction from a channel obstruction directly affects clinical performance and patient safety, making it a functional defect requiring immediate repair.
What is the purpose of the endoscope's universal cord water-resistant cap during reprocessing?
Answer: To protect the electrical light guide connector from fluid exposure during immersion
The water-resistant cap seals the electrical contacts of the light source connector to prevent fluid ingress and short-circuit damage during immersion reprocessing.
A flexible endoscope returned from repair should be subjected to which test before returning to clinical use?
Answer: A full reprocessing cycle followed by leak testing and functional verification
After repair, the scope must undergo complete reprocessing, leak testing, and functional checks to confirm it is both safe and clinically ready.
When evaluating endoscope image quality, 'salt and pepper' artifact in the center of the image most likely indicates:
Answer: Damage to the CCD/CMOS chip pixels
Dead or hot pixels on the CCD/CMOS image sensor appear as fixed 'salt and pepper' noise in the center of the image, indicating sensor damage.
Which practice helps prevent 'scope pooling' damage in an endoscopy unit?
Answer: Rotating scope usage evenly and tracking each scope's procedure count
Rotating scope usage evenly prevents individual scopes from accumulating disproportionate wear, extending the fleet's overall lifespan.
A damaged endoscope elevator mechanism (found on duodenoscopes) that cannot be fully raised or lowered should be:
Answer: Removed from service until repaired by a qualified technician
A malfunctioning elevator mechanism compromises both clinical function and the ability to reprocess the duodenoscope's distal cap area, requiring immediate removal from service.
What does the term 'TASS' stand for in the context of endoscope reprocessing failure investigation?
Answer: Toxic Anterior Segment Syndrome
TASS (Toxic Anterior Segment Syndrome) is a rapid, sterile postoperative inflammation that can result from endoscope reprocessing residue or chemical contamination introduced during ophthalmic procedures.
