Which standard or guideline provides primary direction for endoscope inspection and testing practices in the United States?
Answer: ANSI/AAMI ST91: Flexible and Semi-Rigid Endoscope Processing in Health Care Facilities
ANSI/AAMI ST91 is the primary US standard specifically addressing flexible and semi-rigid endoscope processing, including inspection and testing requirements.
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?
Answer: Don appropriate personal protective equipment (PPE)
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.
What is the significance of inspecting the light guide bundle of an endoscope during visual inspection?
Answer: To identify broken fibers that would reduce illumination quality during procedures
Broken fibers in the light guide bundle reduce illumination, which can impair visualization during procedures and indicate scope damage requiring repair.
When conducting a pressure (leak) test using a manual leak tester, what is the correct sequence of steps?
Answer: Attach tester, pressurize scope, submerge in water, then observe for bubbles
The correct sequence is to attach and pressurize the scope before submerging it, so any breach will immediately produce observable bubbles upon submersion.
An endoscope inspection reveals a small crack in the rubber angulation hood at the distal tip. What action should be taken?
Answer: Remove the scope from service and send to the manufacturer or repair facility
A cracked angulation hood compromises the scope's integrity and can harbor microorganisms; the scope must be removed from service for professional repair.
Which of the following findings during channel patency testing would indicate the working channel is NOT patent?
Answer: Resistance is felt when advancing the cleaning brush and water does not flow freely
Resistance during brush passage combined with impeded water flow indicates a blockage or collapse within the working channel, preventing adequate cleaning and compromising patency.
How should a reprocessing technician document scope inspection findings to support traceability?
Answer: Enter all findings—normal and abnormal—in the scope tracking log with date, time, technician ID, and scope identifier
Comprehensive documentation of all inspection findings with full identifiers supports traceability, quality assurance, and patient safety investigations.
