IAHCSMM CRCST Practice Test – Chapter 15

IAHCSMM CRCST Practice Test – Chapter 15 (Certified Registered Central Service Technician) Practice Test. Chapter 15 primarily focuses on the details of various low-temperature sterilization methods, with an emphasis on their advantages, limitations, and specific operational procedures.

The chapter introduces the need for sterilizer performance monitoring, stressing the importance of physical, chemical, and biological indicators to assess the effectiveness of sterilization, particularly the O3 (ozone) sterilization process.

The chapter also elucidates how sterilizer chambers should be carefully managed to avoid overloading and potential sterilization failure. The use of biological indicators containing Geobacillus stearothermophilus spores is highlighted as a key part of monitoring the sterilization process.
