CRCST Chapter 8 Practice Test: Cleaning and Decontamination

Decontamination is the critical first step in reprocessing — no sterilization method can compensate for inadequate cleaning. This chapter covers every aspect of the decontamination workflow: point-of-use treatment at the surgical site, safe transport to the decontam area, manual and mechanical cleaning methods, proper PPE donning/doffing sequences, and quality assurance steps like protein residual testing. You will learn the correct order for putting on protective equipment (gown first, gloves last over the cuffs), how to select cleaning chemistry based on soil type, why enzymatic detergents work on protein-based bioburden, and how ultrasonic cleaners use cavitation to reach areas brushes cannot. Every subsequent step in reprocessing depends on thorough decontamination performed correctly here.
