C. Cleaning destroys bacteria; disinfecting removes dirt
D. Cleaning requires EPA-registered products; disinfecting does not
Correct ,,,answer,,,: A
Rationale: Cleaning removes visible soil, debris, and organic matter using soap

come into contact with intact skin (e.g., combs, brushes, capes)?
A. Sterilization
,B. High-level disinfection
C. Intermediate-level disinfection
D. Low-level disinfection
Correct ,,,answer,,,: D

disinfection. Intermediate-level disinfection is for semi-critical items. Sterilization
is required for critical items that penetrate the skin.
