CER Quality Assurance and Documentation 2 — Questions and Answers
Question 1: Which document must be completed BEFORE an endoscope is returned to clinical use after reprocessing?
- Incident report
- Reprocessing log confirming all steps were completed (Correct answer)
- Manufacturer warranty card
- Patient consent form
Correct answer: Reprocessing log confirming all steps were completed
A completed reprocessing log verifying all steps were performed is required before an endoscope is cleared for clinical use.
Question 2: What is the primary purpose of tracking lot numbers for disinfectants in endoscope reprocessing documentation?
- To calculate inventory costs
- To enable traceability during product recalls or quality failures (Correct answer)
- To satisfy manufacturer warranty requirements
- To document employee training hours
Correct answer: To enable traceability during product recalls or quality failures
Lot number tracking enables targeted recall response and root cause analysis if a specific disinfectant batch is found defective.
Question 3: A reprocessing technician discovers an AER cycle was interrupted mid-cycle. What is the FIRST action?
- Restart the AER cycle immediately
- Document the interruption and quarantine the scope (Correct answer)
- Report to infection control only after completing the cycle
- Return the scope to storage pending further review
Correct answer: Document the interruption and quarantine the scope
The scope must be quarantined and the event documented before any further action to preserve safety and traceability.
Question 4: Which QA indicator directly measures the effectiveness of manual cleaning before high-level disinfection?
- AER cycle time log
- Residual protein test (e.g., ATP or protein assay) (Correct answer)
- MEC test strip result
- Leak test pressure reading
Correct answer: Residual protein test (e.g., ATP or protein assay)
Residual protein or ATP testing detects organic soil remaining after manual cleaning, which could interfere with HLD.
Question 5: How long must endoscope reprocessing records typically be retained according to standard accreditation guidelines?
- 6 months
- 1 year
- A minimum of 3 years, often longer per state law or facility policy (Correct answer)
- Until the endoscope is decommissioned
Correct answer: A minimum of 3 years, often longer per state law or facility policy
Most accreditation bodies require reprocessing records to be kept a minimum of 3 years, though state laws or facility policies may extend this.
Question 6: What information is LEAST likely to be required on a standard endoscope reprocessing log?
- Technician ID or initials
- Patient name or procedure room number (Correct answer)
- Disinfectant lot number and expiration date
- Scope serial number
Correct answer: Patient name or procedure room number
Reprocessing logs track the scope and chemicals, not patient-identifying information, which is stored in procedure records.
Question 7: A quality audit reveals that MEC strips are being tested only at the start of each shift rather than before each use. This is MOST concerning because:
- It wastes test strips unnecessarily
- Disinfectant concentration can drop below effective levels between uses during a shift (Correct answer)
- Manufacturers require hourly testing
- OSHA mandates per-use MEC testing
Correct answer: Disinfectant concentration can drop below effective levels between uses during a shift
MEC can fall below the minimum effective concentration during a shift as scopes are processed, making per-use testing essential.
