Final answer:
Process indicators that change color are useful for monitoring sterilization and determining whether an instrument package has been processed properly.
Step-by-step explanation:
Process indicators that change color are useful for monitoring sterilization. They can help identify whether an instrument package has been processed properly.
One type of indicator is heat-sensitive autoclave tape, which turns black when the appropriate temperature for sterilization is achieved during an autoclave run. Another type is a biological indicator spore test, which uses endospores of bacteria that are resistant to heat to determine if the sterilization process is effective. Additionally, Diack tubes containing temperature-sensitive pellets can be used as autoclave indicators.
Overall, these process indicators are valuable tools for ensuring that sterilization has been performed correctly.
