Free CER Principles and Maintenance Questions and Answers

Question 1

What is the maximum recommended relative humidity for endoscope storage?

Accepted Answer

60%

Answer

Explanation:
The relative humidity should not exceed 60% for endoscope storage to prevent moisture-related damage and microbial growth. High humidity levels can promote the proliferation of microorganisms and lead to corrosion or deterioration of endoscope components. Therefore, maintaining humidity below 60% helps ensure the integrity and effectiveness of the reprocessing process.

Question 2

How should the airflow be designed in the soiled and decontamination areas of an endoscope reprocessing facility?

Accepted Answer

Air flows into the area (negative pressure)

Answer

Explanation:
The soiled and decontamination areas in an endoscope reprocessing facility should be designed with negative pressure, meaning air flows into the area. Negative pressure helps prevent the spread of contaminants by ensuring that any airborne particles or microorganisms are contained within the designated area, reducing the risk of cross-contamination to adjacent spaces.

Question 3

What is the minimum number of air exchanges per hour recommended for the soiled and decontamination areas in an endoscope reprocessing facility?

Accepted Answer

10

Answer

Explanation:
The soiled and decontamination areas in an endoscope reprocessing facility should hold a minimum of 10 air exchanges per hour. This ensures adequate ventilation and helps remove airborne contaminants, maintaining a clean and safe environment for endoscope reprocessing activities.

Question 4

What may cause a blown endoscope during ethylene oxide sterilization?

Accepted Answer

The endoscope is not vented properly

Answer

Explanation:
Ethylene oxide sterilization of a flexible endoscope may result in a blown endoscope if the endoscope is not vented properly. Ethylene oxide gas can build up within the endoscope during the sterilization process, leading to pressure buildup and potential damage to the endoscope's components. Proper venting ensures the safe release of gas and prevents the risk of a blown endoscope.

Question 5

Which type of scope is used to identify soil or damage within a lumen that cannot be seen by manual visual inspection?

Accepted Answer

Borescope

Answer

Explanation:
A borescope is specifically designed to identify soil or damage within a lumen that cannot be seen by manual visual inspection. It is a useful tool for inspecting hard-to-reach areas and ensuring thorough cleaning and reprocessing of endoscopes.
