MDRAO Sterile Storage, Handling, and Distribution 4 — Questions and Answers
Question 1: What is the purpose of positive air pressure in a sterile storage room?
- To prevent unfiltered air from surrounding areas from entering (Correct answer)
- To keep instruments dry by evaporating moisture
- To reduce static electricity on packaging surfaces
- To circulate air to maintain consistent temperature
Correct answer: To prevent unfiltered air from surrounding areas from entering
Positive air pressure in sterile storage rooms causes air to flow outward when doors open, preventing contaminated air from entering.
Question 2: Which personnel are generally permitted access to sterile storage areas?
- Only authorized sterile processing and clinical staff (Correct answer)
- Any hospital staff member requiring supplies
- Vendors during restocking deliveries
- All staff including housekeeping at all times
Correct answer: Only authorized sterile processing and clinical staff
Access to sterile storage areas should be restricted to authorized personnel to minimize contamination and security risks.
Question 3: When inspecting a sterile package before distribution, which finding would indicate the package should NOT be used?
- A peel-pouch with a lifted or non-uniform seal edge (Correct answer)
- A chemical indicator that has changed to the target color
- A label with a lot number and sterilization date
- A package that feels slightly firm due to its contents
Correct answer: A peel-pouch with a lifted or non-uniform seal edge
A lifted or non-uniform seal edge indicates a potential channel breach in the sterile barrier that could allow microbial ingress.
Question 4: How should sterile items be handled to minimize the risk of contamination during transport to the operating room?
- Placed in a covered, closed transport cart or container (Correct answer)
- Carried by hand with sterile gloves and a mask
- Placed on an open tray covered with a sterile drape
- Transported in an open cart moving quickly through corridors
Correct answer: Placed in a covered, closed transport cart or container
Covered, closed transport systems protect sterile items from airborne and contact contamination during transport.
Question 5: Which action should be taken when a sterile item is returned from an operating room unused?
- Inspect the package thoroughly before returning to sterile stock or reprocessing (Correct answer)
- Return it directly to the sterile storage shelf without inspection
- Sterilize it again as a precaution regardless of package condition
- Tag it as 'used' and place it in the biohazard bin
Correct answer: Inspect the package thoroughly before returning to sterile stock or reprocessing
Returned unused items must be carefully inspected for any sign of compromise before a decision is made to return to stock or reprocess.
Question 6: What is the role of air change rates in sterile storage room design?
- To dilute and remove airborne contaminants by replacing room air regularly (Correct answer)
- To adjust temperature automatically based on occupancy
- To provide positive pressure during sterilization cycles
- To maintain carbon dioxide levels for staff safety
Correct answer: To dilute and remove airborne contaminants by replacing room air regularly
Adequate air changes per hour (ACH) dilute and remove airborne particulates and microorganisms, maintaining the cleanliness of the sterile storage environment.
Question 7: Cardboard shipping boxes should NOT be brought into sterile storage areas primarily because:
- They harbor insects, mold spores, and dust that can contaminate sterile packages (Correct answer)
- They obscure item labels and expiration dates
- They make inventory tracking more difficult
- They are combustible and present a fire hazard
Correct answer: They harbor insects, mold spores, and dust that can contaminate sterile packages
Cardboard boxes can carry insects, mold, and particulate contamination from warehouse and shipping environments into clean sterile storage.
