MDRAO Identification 2 — Questions and Answers
Question 1: Which characteristic is used to differentiate a critical medical device from a semi-critical one during identification?
- Contact with intact skin only
- Contact with sterile body cavities or vascular system (Correct answer)
- Contact with mucous membranes only
- Contact with non-intact skin
Correct answer: Contact with sterile body cavities or vascular system
Critical devices contact sterile tissue or the vascular system and require sterilization, distinguishing them from semi-critical items.
Question 2: When identifying a flexible endoscope, which feature most directly determines its reprocessing classification?
- The length of the insertion tube
- The manufacturer's country of origin
- The body cavities and tissue types it contacts during use (Correct answer)
- The color-coded handle
Correct answer: The body cavities and tissue types it contacts during use
The Spaulding classification of an endoscope is based on which body sites and tissue types it contacts, not physical dimensions or cosmetic features.
Question 3: A technician finds a tray with mixed instruments and no accompanying paperwork. What is the correct first step?
- Reprocess all items using the most stringent method available
- Discard the entire tray as unidentifiable
- Quarantine the tray and contact the originating department for identification (Correct answer)
- Sort by visual appearance and proceed
Correct answer: Quarantine the tray and contact the originating department for identification
Unidentified items must be quarantined and traced back to their source before any reprocessing decision is made.
Question 4: Which label element is MOST critical when identifying a sterilized package at the point of use?
- Package color
- Sterilization lot number and expiry date (Correct answer)
- Technician's initials
- Tray weight notation
Correct answer: Sterilization lot number and expiry date
The sterilization lot number and expiry date allow traceability and confirm whether the package remains within its sterile shelf life.
Question 5: How should a CS technician identify an implantable device that arrives without its original packaging?
- Proceed with standard reprocessing immediately
- Use the device's physical markings and cross-reference manufacturer records (Correct answer)
- Classify it as non-critical by default
- Return it to the OR without reprocessing
Correct answer: Use the device's physical markings and cross-reference manufacturer records
Implantables must be positively identified using engraved markings, serial numbers, or manufacturer records before any reprocessing step.
Question 6: Which of the following best describes a 'loaner instrument' identification challenge in MDRAO practice?
- Loaner instruments always arrive pre-sterilized and ready for use
- Loaner inventories may lack facility-standard labeling and require verification (Correct answer)
- Loaners are classified as non-critical by regulatory default
- Loaner instruments cannot be reprocessed in hospital CSDs
Correct answer: Loaner inventories may lack facility-standard labeling and require verification
Loaner instruments from external vendors often lack standard facility labels and must be inventoried and verified against manufacturer IFU before reprocessing.
Question 7: A rigid container is returned from the OR with its filter intact but the external chemical indicator shows an abnormal color change. What should the technician do?
- Accept the set since the filter is intact
- Reject the set, quarantine it, and investigate before reuse (Correct answer)
- Re-sterilize immediately without further assessment
- Document and release if the internal indicator is acceptable
Correct answer: Reject the set, quarantine it, and investigate before reuse
An abnormal external chemical indicator is a sterilization failure signal; the set must be quarantined and investigated regardless of other findings.
