Colorado Esthetician Written Practice Exam

What does sterilization use in an autoclave?

1. High-pressure steam under dry heat

2. Chemical disinfectants

3. Soap and water

4. Low-pressure steam under dry heat

The correct answer is: High-pressure steam under dry heat

The correct answer is A: High-pressure steam under dry heat. Sterilization in an autoclave involves using high-pressure steam under dry heat to kill all forms of microbial life, including bacteria, viruses, fungi, and spores. This method is highly effective in achieving complete sterilization of tools and equipment used in esthetician practices. Chemical disinfectants, soap and water, and low-pressure steam under dry heat are not as effective as high-pressure steam under dry heat for achieving sterilization in an autoclave.
