✍️ Sample CER Questions & Answers
1. Which of the following is a key preventive maintenance practice performed by reprocessing staff to avoid costly repairs to the light guide connector?
The waterproof cap is essential for protecting the sensitive electrical contacts and components within the light guide connector from fluid invasion during cleaning and disinfection. Failure to secure the cap properly is a leading cause of major, expensive repairs due to fluid damage.
2. How should a reprocessing 'near-miss' event be handled?
Near-miss events provide valuable learning opportunities and must be formally documented and investigated to prevent future failures that could harm patients.
3. What is the primary hazard of using an endoscope with a bent or kinked insertion tube?
Kinking compresses internal channels, preventing brush passage and adequate disinfectant contact, and weakens the insertion tube structurally.
4. What is a 'competency validation' in the context of endoscope reprocessing staff?
Competency validation is an objective, documented assessment demonstrating that each staff member performs reprocessing correctly per established standards.
5. What does 'process monitoring' mean in the context of AER cycle quality assurance?
Process monitoring involves reviewing AER printouts or electronic logs confirming that all cycle parameters met validated requirements for effective disinfection.
6. What is the purpose of designating specific personal protective equipment for the soiled and clean zones of the reprocessing area?
Zone-specific PPE ensures that contaminated outer garments are removed before entering the clean zone, preventing cross-contamination.
