CRCST Practice Test 2024 (UPDATED ALL CHAPTERS)

Chapter 17 of the CRCST manual emphasizes the importance of monitoring the disinfection and sterilization processes. Mistakes in these areas can lead to severe patient harm due to infections. As a technician, understanding the different methods to monitor these processes and knowing how to interpret results can significantly impact patient outcomes.

Physical Indicators: These monitors, including time, temperature, and pressure recorders, ensure that the sterilization parameters have been met.
Chemical Indicators (CI): CIs change color to indicate exposure to the sterilization process. These are placed both outside (external) and inside (internal) the sterilization packages.
Biological Indicators (BI): BIs are essentially live bacterial spores placed in sterilizers to verify that the sterilization process kills even the most resistant microorganisms.
