What does a "pass" reading of a Chemical Indicator (CI) signify?

  1. The autoclave needs maintenance

  2. The parameters for sterilization have not been met

  3. The parameters for sterilization have been met

  4. There is a need for immediate reprocessing

The correct answer is: The parameters for sterilization have been met

A "pass" reading of a Chemical Indicator (CI) signifies that the parameters for sterilization have been met. Chemical Indicators are designed to change color or display a specific signal when the sterilization conditions are achieved. Therefore, a "pass" reading indicates that the sterilization process was successful and the instruments can be considered sterile. This is why option C is the correct answer. Options A, B, and D are incorrect because they do not accurately reflect the meaning of a "pass" reading for a Chemical Indicator.
