CER Scope Inspection and Testing Questions and Answers 5

Question 1

Which of the following best describes 'channel integrity testing' as part of endoscope inspection?

Accepted Answer

Verifying that internal channels are unobstructed, undamaged, and able to be effectively cleaned

Answer

Channel integrity testing ensures that all internal channels are free of obstructions, structurally intact, and amenable to effective cleaning and disinfection.

Question 2

A reprocessing technician notices the outer sheath of a duodenoscope has a small raised bump along the insertion tube. What does this finding most likely indicate?

Accepted Answer

A kink or internal separation that may affect scope performance and integrity

Answer

A raised bump or bulge on the insertion tube sheath often signals internal damage such as a kink, broken wire, or sheath separation that can compromise scope function and reprocessing efficacy.

Question 3

After reprocessing, a technician performs a final visual inspection and finds water droplets inside the objective lens of a colonoscope. What does this indicate?

Accepted Answer

Fluid ingress through a breach in the distal optics, indicating scope damage

Answer

Moisture inside the objective lens indicates that fluid has breached the optical seal, which is a sign of scope damage requiring removal from service and repair.

Question 4

What is the recommended action when an endoscope's elevator mechanism (found on duodenoscopes) is stiff or difficult to operate during functional testing?

Accepted Answer

Remove the scope from service for inspection and potential repair

Answer

A stiff elevator mechanism may indicate damage, debris accumulation, or mechanical failure that impairs the device's function and requires professional evaluation.

Question 5

During pre-procedure inspection, a clinician reports that the image on the video processor appears blurry despite the scope passing all reprocessing checks. Which inspection step is most relevant to this finding?

Accepted Answer

Distal lens and optical system visual inspection

Answer

Image blurriness is most likely related to a soiled, damaged, or moisture-affected distal lens or optical system, making optical inspection the most relevant step.
