,9. What must be done before placing an endoscope into automated reprocessing equipment?
- Answer: Thorough manual cleaning must be performed. ✔️
10. How does the U.S. Food and Drug Administration (FDA) define validation?
- Answer: Validation is establishing, through objective evidence, that a process consistently yields a
result or product that meets predetermined specifications.
11. What are the seven general steps for manually cleaning flexible endoscopes?
1. Submerge the endoscope completely in a detergent/enzymatic solution.
2. Manually clean all internal and external surfaces, including brushing all internal channels that can
be cleaned.
3. Attach appropriate cleaning adapters following the endoscope manufacturer’s instructions.
4. Flush each internal channel with detergent or enzymatic solution.
5. Soak in detergent/enzymatic solution for the recommended duration as per the manufacturer’s
guidelines.
6. Rinse and submerge the endoscope in clean water; flush the channels.
7. Remove water from the channels by flushing them with air.
12. What should cleaning verification of flexible and semi-rigid endoscopes entail?
1. Visual inspection alongside other verifications to assess both external surfaces and internal
channels.
2. Testing the effectiveness of mechanical cleaning equipment.
3. Monitoring key cleaning parameters.
13. What are the risks associated with delayed processing of endoscopes?
- Answer: Delayed processing allows biofilm formation and soil to dry, making it more challenging to
clean the endoscope effectively.
14. What federal agency is responsible for health promotion and prevention activities in the U.S., which
also aims to enhance public health?

- Answer: It refers to the end of an item that is farthest from the point of origin; for example, the
distal end of the femur is closest to the knee.
17. What are the three main objectives when transporting contaminated endoscopes?
1. Deliver the endoscope promptly.
2. Prevent cross-contamination during transport.
3. Protect the endoscope from damage.
18. What is the risk of a flexible endoscope that has not undergone leak testing?
1. Damaged endoscopes are susceptible to fluid invasion.
2. Unnoticed damage can hinder future procedures.
19. What is the term for fluid invading internal sections of an endoscope, leading to damage?
- Answer: Fluid invasion.
20. What are the eight steps for conducting leak testing on an endoscope?
1. Inspect for tears and damage.
2. Remove suction, air, and water valves.
3. Connect the endoscope to the leak test device.
4. Pressurize, submerging the distal portion; flex, submerge, and inspect the control head.
5. Look for bubbles and signs of damage.
6. Remove the endoscope from water and drain it.
, 7. Release the pressure from the endoscope.
8. Disconnect from the leak tester.
21. What enzyme helps break down fatty deposits, such as bone marrow and adipose tissue?
- Answer: Lipase.
22. What enzyme catalyzes the change of starch?
- Answer: Amylase.
23. True or False: Pre-cleaning at the point of use reduces the chance of biofilm formation.
- Answer: True
24. True or False: Pre-cleaning at the point of use should happen before the endoscope is detached from
the power source.
- Answer: True
25. What is the first action in point-of-use pre-cleaning after removing the endoscope from the patient?
- Answer: Remove any gross soil.
26. When placing the pre-cleaned endoscope in a container for transport, should all accessories used
during the procedure be included?
- Answer: False
27. What is the primary objective of leak testing?
- Answer: To detect any damage present on the interior and exterior of the endoscope.
The endoscope can be returned to circulation to be used for surgery if the leakage is very minimal after
leak testing
false
Pre cleaning at the point of use increase the likelihood of biofilm formation
