    The bowie-dick test ensures that the prevac sterilizer is:

    • Reaching the correct temperature

    • Properly removing all the air from the sterilizer during cycles

    • Supplying the proper amount of gluteraldehyde

    • Reaching the correct psi

    Correct Answer
    A. Properly removing all the air from the sterilizer during cycles
    Explanation
    The Bowie-Dick test is used to ensure that the prevac sterilizer is properly removing all the air from the sterilizer during cycles. This is important because the presence of air can prevent proper sterilization and can lead to ineffective sterilization of medical instruments and equipment. The Bowie-Dick test involves placing a specific test pack in the sterilizer and running a specific cycle to check for the presence of air leaks. If the test indicates that the sterilizer is properly removing all the air, it ensures that the sterilization process is effective and the instruments are properly sterilized.
