CER Scope Inspection and Testing Questions and Answers 4

Question 1

Which standard or guideline provides primary direction for endoscope inspection and testing practices in the United States?

Accepted Answer

ANSI/AAMI ST91: Flexible and Semi-Rigid Endoscope Processing in Health Care Facilities

Answer

ANSI/AAMI ST91 is the primary US standard specifically addressing flexible and semi-rigid endoscope processing, including inspection and testing requirements.

Question 2

A gastroscope is returned from the endoscopy suite with visible debris on the exterior of the distal tip. Prior to beginning the inspection process, what is the FIRST step a reprocessing technician should take?

Accepted Answer

Don appropriate personal protective equipment (PPE)

Answer

Donning appropriate PPE is always the first step when handling a contaminated endoscope to protect the technician from exposure to blood, body fluids, and pathogens.

Question 3

What is the significance of inspecting the light guide bundle of an endoscope during visual inspection?

Accepted Answer

To identify broken fibers that would reduce illumination quality during procedures

Answer

Broken fibers in the light guide bundle reduce illumination, which can impair visualization during procedures and indicate scope damage requiring repair.

Question 4

When conducting a pressure (leak) test using a manual leak tester, what is the correct sequence of steps?

Accepted Answer

Attach tester, pressurize scope, submerge in water, then observe for bubbles

Answer

The correct sequence is to attach and pressurize the scope before submerging it, so any breach will immediately produce observable bubbles upon submersion.

Question 5

An endoscope inspection reveals a small crack in the rubber angulation hood at the distal tip. What action should be taken?

Accepted Answer

Remove the scope from service and send to the manufacturer or repair facility

Answer

A cracked angulation hood compromises the scope's integrity and can harbor microorganisms; the scope must be removed from service for professional repair.
