Which statement correctly identifies the role of process indicators in sterilization monitoring?

• A. Biological indicators confirm the item has been through the sterilization cycle.
• B. Chemical indicators confirm exposure to appropriate conditions.
• C. Biological indicators confirm packaging integrity.
• D. Process indicators confirm the item has been through the sterilization cycle.

Answer: (D)

Process indicators are used to show that a sterilization cycle has been completed for a load. They respond to the cycle’s exposure (temperature, time, etc.) and give a visible signal that the item has been through the process. This helps staff confirm the pack entered and progressed through the sterilizer, but it does not prove sterility by itself—that’s what biological indicators are for, by testing whether spores were killed. Chemical indicators, meanwhile, indicate exposure to the right conditions, but process indicators specifically confirm the cycle occurred.
