IAHCSMM Packaging, Wrapping & Storage 1 — Questions and Answers
Question 1: What is the primary function of sterile packaging?
- To keep instruments organized
- To maintain sterility from the point of sterilization to the point of use (Correct answer)
- To prevent instrument damage during transport
- To label instruments for inventory tracking
Correct answer: To maintain sterility from the point of sterilization to the point of use
Sterile packaging forms a microbial barrier that maintains the sterility of processed instruments until they are needed for use.
Question 2: Which of the following is an example of a nonwoven packaging material?
- Muslin
- SMS (spunbond-meltblown-spunbond) polypropylene wrap (Correct answer)
- Cotton lint-free cloth
- Linen sterilization towels
Correct answer: SMS (spunbond-meltblown-spunbond) polypropylene wrap
SMS polypropylene is a nonwoven synthetic material widely used for wrapping instruments; it provides an effective microbial barrier and is water-resistant.
Question 3: When using the sequential (double) wrap method, the second wrap is applied:
- In the same direction as the first wrap
- At a 90-degree angle to the first wrap for maximum coverage (Correct answer)
- Only if the first wrap is visibly damaged
- After sterilization is complete
Correct answer: At a 90-degree angle to the first wrap for maximum coverage
The second wrap in the sequential method is applied at a 90-degree angle to the first, ensuring no gaps and creating an aseptic presentation package.
Question 4: What is the purpose of event-related sterility maintenance?
- Items expire based on calendar date regardless of storage conditions
- Sterility is maintained indefinitely as long as the package integrity is not compromised (Correct answer)
- Items must be re-sterilized weekly
- All items expire after 30 days
Correct answer: Sterility is maintained indefinitely as long as the package integrity is not compromised
Event-related sterility holds that a properly packaged item remains sterile until an event (tear, moisture, compromise) occurs, not based solely on a calendar date.
Question 5: What minimum seal width is required for heat-sealed peel pouches per AAMI standards?
- 1 mm
- 3 mm
- 6 mm (Correct answer)
- 10 mm
Correct answer: 6 mm
AAMI recommends a minimum 6 mm continuous seal width to ensure an effective microbial barrier in heat-sealed peel pouches.
Question 6: Which of the following conditions should cause a sterile package to be rejected before use?
- Package stored longer than 6 months
- Package sealed with a heat sealer rather than tape
- Package shows moisture stains or wet marks (Correct answer)
- Package label written in permanent marker
Correct answer: Package shows moisture stains or wet marks
Moisture stains indicate the package may have been wet, which compromises the microbial barrier and must be treated as non-sterile.
