CER Automated Endoscope Reprocessors 5 — Questions and Answers
Question 1: Which regulatory body requires that AER use be documented in the endoscope's reprocessing log?
- FDA only
- OSHA and The Joint Commission (TJC) (Correct answer)
- EPA alone
- No regulatory body requires this documentation
Correct answer: OSHA and The Joint Commission (TJC)
Both OSHA and The Joint Commission require documentation of reprocessing steps, including AER use, to ensure traceability and compliance.
Question 2: If an AER's chemical disinfectant concentration test (MEC strip) fails at the start of a cycle, what should the technician do?
- Complete the cycle and re-test at the end
- Discard the solution and replenish per the IFU before reprocessing (Correct answer)
- Dilute the solution with water to adjust concentration
- Proceed—the AER compensates automatically
Correct answer: Discard the solution and replenish per the IFU before reprocessing
A failed MEC test means the disinfectant is below the minimum effective concentration; the solution must be discarded and replaced per the IFU before use.
Question 3: An AER manufacturer's IFU states the cycle time is 25 minutes. A facility's staff reduces the cycle to 20 minutes to increase throughput. This practice is:
- Acceptable if the disinfectant concentration is doubled
- A violation of manufacturer IFU and regulatory standards (Correct answer)
- Permissible with department manager approval
- Allowable only for short flexible endoscopes
Correct answer: A violation of manufacturer IFU and regulatory standards
Deviating from the manufacturer's validated cycle time is a violation of the IFU and regulatory standards and may result in inadequate disinfection.
Question 4: Regarding compatibility, what must a facility verify before using a new endoscope model in an existing AER?
- That the endoscope fits physically in the AER basket
- That both the endoscope and AER manufacturers have confirmed compatibility (Correct answer)
- That the same disinfectant brand has always been used
- That the endoscope is under warranty
Correct answer: That both the endoscope and AER manufacturers have confirmed compatibility
Both the endoscope and AER manufacturers must confirm compatibility, as incompatible combinations can damage the endoscope or result in inadequate reprocessing.
Question 5: What is the role of the self-disinfection cycle on an AER?
- It sterilizes the machine's exterior surfaces
- It decontaminates the AER's internal fluid pathways to prevent cross-contamination (Correct answer)
- It tests the machine's mechanical function only
- It is optional and rarely recommended
Correct answer: It decontaminates the AER's internal fluid pathways to prevent cross-contamination
The AER self-disinfection cycle treats the machine's internal fluid pathways to prevent buildup of microorganisms that could contaminate processed endoscopes.
Question 6: Which of the following BEST describes the purpose of leak testing an endoscope BEFORE placing it in an AER?
- To check that the endoscope connector fits the AER manifold
- To detect internal damage that would allow fluid ingress and cause scope damage during reprocessing (Correct answer)
- To measure disinfectant absorption by the scope
- To verify the scope's optical quality
Correct answer: To detect internal damage that would allow fluid ingress and cause scope damage during reprocessing
Leak testing before AER processing identifies breaches in the endoscope's internal integrity, which if undetected would allow reprocessing fluids to damage internal components.
Question 7: An AER that uses peracetic acid (PAA) as the disinfectant requires special consideration regarding:
- Extended drying cycles only
- Material compatibility, disposal regulations, and staff exposure limits for PAA (Correct answer)
- Refrigeration of the disinfectant between cycles
- Use only with rigid endoscopes
Correct answer: Material compatibility, disposal regulations, and staff exposure limits for PAA
PAA-based AER systems require attention to material compatibility with scope components, proper chemical disposal per EPA regulations, and monitoring of staff exposure to PAA fumes.
