Decontamination第 15 / 100 题
What is the purpose of the elevated-temperature rinse phase, often around 180 degrees F or higher, in a washer-disinfector cycle?
a.It sterilizes the instruments so they can bypass terminal sterilization
b.It activates the enzymatic detergent so proteins continue to break down
c.It provides thermal disinfection that reduces microbial load and improves drying
d.It cools the load gradually to prevent thermal shock to delicate instruments
解析
The hot rinse delivers thermal disinfection, lowering the bioburden so items can be safely handled in the clean workroom, and the residual heat helps the load dry. Thermal disinfection is not sterilization, so terminal sterilization is still required for critical devices. Enzymes are destroyed at that temperature, and the phase heats rather than cools the load.
