MDRAO Identification 5 — Questions and Answers
Question 1: During incoming inspection of a loaner surgical set, the manifest lists 47 instruments but only 45 are present. What is the correct MDRAO-aligned response?
- Proceed with reprocessing using the 45 available instruments
- Document the discrepancy, notify the vendor, and do not release the set until resolved (Correct answer)
- Substitute similar instruments from facility stock without notification
- Return the entire set without documentation
Correct answer: Document the discrepancy, notify the vendor, and do not release the set until resolved
Discrepancies between loaner manifests and actual counts must be documented and reported to the vendor; the set cannot be released to the OR until reconciled.
Question 2: Which characteristic helps identify that an endoscope requires high-level disinfection rather than sterilization under the Spaulding classification?
- It enters sterile body cavities
- It contacts only intact mucous membranes without entering sterile tissue (Correct answer)
- It contacts only intact skin
- It is used exclusively for diagnostic imaging outside the body
Correct answer: It contacts only intact mucous membranes without entering sterile tissue
Semi-critical devices contact intact mucous membranes and require high-level disinfection as a minimum, distinguishing them from critical devices requiring sterilization.
Question 3: A technician notices that a chemical indicator strip placed inside a pack has not changed color after sterilization. What does this finding indicate?
- The sterilization cycle was successful
- Sterilizing conditions may not have been reached inside the pack; the load should be quarantined (Correct answer)
- The indicator was expired and can be ignored
- The pack requires re-wrapping only
Correct answer: Sterilizing conditions may not have been reached inside the pack; the load should be quarantined
A non-color-changed internal chemical indicator signals that sterilizing parameters were not met inside the pack, requiring quarantine and investigation.
Question 4: In MDRAO standards, what is the significance of identifying a device's 'compatibility' with a specific sterilization agent?
- Compatibility is irrelevant if the cycle time is extended
- Incompatible materials can be damaged or rendered unsafe, and sterilization efficacy may be compromised (Correct answer)
- All sterilization agents are universally compatible with every device
- Compatibility only matters for single-use devices
Correct answer: Incompatible materials can be damaged or rendered unsafe, and sterilization efficacy may be compromised
Material incompatibility with sterilants can cause device degradation, patient injury, or sterilization failure, making compatibility identification essential before processing.
Question 5: Which biological indicator organism is used to challenge steam sterilization cycles for identification of process efficacy?
- Bacillus anthracis spores
- Geobacillus stearothermophilus spores (Correct answer)
- Clostridium difficile vegetative cells
- Staphylococcus aureus cultures
Correct answer: Geobacillus stearothermophilus spores
Geobacillus stearothermophilus is the standard biological indicator organism for steam sterilization due to its high heat resistance.
Question 6: When a technician identifies an instrument as 'delicate' during tray assembly, which handling modification is MOST appropriate?
- Place the instrument at the bottom of the tray for stability
- Use protective tip guards and position to avoid contact with heavier instruments (Correct answer)
- Sterilize delicate instruments at higher temperatures for faster cycles
- Omit the instrument from the tray to prevent damage
Correct answer: Use protective tip guards and position to avoid contact with heavier instruments
Delicate instruments require tip guards and strategic placement to prevent damage during sterilization and transport, as identified in assembly protocols.
Question 7: According to MDRAO guidelines, what action is required when a sterilization process parameter printout cannot be retrieved for a completed load?
- Release the load based on visual inspection of packages only
- Quarantine the load and investigate the documentation failure before any items are released (Correct answer)
- Re-sterilize the load without documentation
- Accept the load if the biological indicator result was negative
Correct answer: Quarantine the load and investigate the documentation failure before any items are released
Without verifiable process parameter documentation, sterility cannot be confirmed; the load must be quarantined until records are recovered or the load is re-sterilized with full documentation.
