  1. According to ANSI/AAMI ST79, which class of chemical indicator is considered the most sophisticated internal indicator for steam sterilization?

    Answer: Class 6

    Class 6 emulating indicators are cycle-specific and react to all critical sterilization parameters, making them the most sophisticated internal indicator.

  2. Which of the following is a contraindication for using a paper/plastic peel pouch?

    Answer: Sharp or pointed instruments that could puncture the packaging

    Sharp or pointed instruments can puncture peel pouches, compromising the sterile barrier and requiring rigid or puncture-resistant packaging instead.

  3. How should rigid sterilization container filters be inspected before use?

    Answer: Checked for holes, tears, or contamination and replaced if compromised

    Container filters must be visually inspected for physical damage such as holes or tears and replaced if any defects are found to maintain sterile barrier integrity.

  4. What information must be included on the external label of a sterilized package?

    Answer: Contents, sterilization date, lot number, and technician ID

    Labels must include contents, sterilization date or load number, lot/load control number, and technician identifier for traceability.

  5. Which type of packaging is required for ethylene oxide (EO) sterilization to allow adequate gas penetration and aeration?

    Answer: Permeable materials such as paper/plastic pouches or nonwoven wraps

    EO sterilization requires permeable packaging materials to allow gas penetration during sterilization and aeration of residuals afterward.

  6. When wrapping instruments using the envelope (diagonal) fold technique, which part of the wrap forms the final closure flap?

    Answer: The last fold (top point) tucked under

    In envelope wrapping, the top point is the final fold and is tucked under to secure the package, forming the closure flap that is pulled first during opening.

  7. What is the primary reason sterile packages should not be stored on the floor?

    Answer: Floors introduce compression damage and microbial contamination risks

    Floor storage exposes packages to compression damage, moisture, and microbial contamination from foot traffic and cleaning activities.
