Which of the following is true about a Class 5 indicator?

It reacts only to temperature

It is used for chemical compatibility testing

It is designed to react to all critical sterilization parameters

A Class 5 indicator is specifically designed for complex sterilization processes, providing a more comprehensive assessment compared to simpler indicators. Unlike lower classes that may only reflect temperature or other individual parameters, a Class 5 indicator integrates multiple critical sterilization parameters, such as temperature, time, and pressure, into its performance. This capability ensures that the sterilization process is effective and that the conditions necessary for sterilization have been met.

The other options do not accurately represent the characteristics of a Class 5 indicator. For example, some indicators may only focus on temperature or cleaning status, but a Class 5 indicator goes beyond that by confirming that all aspects of the sterilization process are correctly executed, making it a reliable choice for ensuring overall efficacy in sterilization procedures.
