Read the first 7 Packaging flashcards as text

  1. What is the primary purpose of using a load control number (lot number) on sterilized packages?

    Answer: To enable recall of items from a specific sterilizer load if a failure occurs

    Load control numbers enable traceability so that all packages from a specific sterilizer load can be identified and recalled if a sterilization failure is discovered.

  2. Which packaging material is NOT compatible with hydrogen peroxide (H2O2) plasma sterilization?

    Answer: Cellulose-based (paper) materials

    Cellulose-based materials such as paper absorb hydrogen peroxide, interfering with the sterilization process; only non-cellulose materials are compatible with H2O2 plasma.

  3. How should a peel pouch be loaded into the sterilizer for optimal steam sterilization?

    Answer: Plastic side down, paper side up

    Peel pouches should be placed plastic side down and paper side up (or on edge) to allow air removal from the paper side and proper steam penetration.

  4. What is the significance of a package passing a Dye Penetration Test?

    Answer: The seal has adequate integrity with no channels or pinholes

    A dye penetration test detects channels, pinholes, or seal defects by showing dye migration into the sealed area, confirming or denying adequate seal integrity.

  5. When packaging a complex instrument with lumens, what additional packaging consideration is required?

    Answer: Ensure the lumen is open and positioned to allow sterilant to flow through

    Lumened instruments must be packaged with lumens open and positioned to allow sterilant (steam or gas) to flow through the channel to ensure sterilization of internal surfaces.

  6. What is the correct storage environment for sterile supply storage areas according to AAMI guidelines?

    Answer: Temperature 60-75°F (16-24°C), relative humidity 30-60%

    AAMI recommends sterile storage areas maintain temperatures of 60-75°F and relative humidity of 30-60% to prevent packaging degradation and maintain sterile barrier integrity.

  7. Which of the following statements about event-related sterility is accurate?

    Answer: Sterility is maintained as long as the package integrity is not compromised

    Event-related sterility means a package is considered sterile until an event (such as damage, moisture, or contamination) compromises the package integrity, not based on a fixed time.
