esthetics practice according to universal precautions?
A. Rinse with warm water and air dry
B. Immerse in an EPA-registered hospital-grade disinfectant for the manufacturer's

CORRECT ANSWER: B. Immerse in an EPA-registered hospital-grade disinfectant
for the manufacturer's specified contact time
Rationale: Proper disinfection requires using an EPA-registered hospital-grade
disinfectant and maintaining the tool in the solution for the full contact time specified
by the manufacturer to ensure destruction of pathogens. This is mandated by OSHA and
state boards to prevent cross-contamination.
Question 8: Which ingredient is commonly used in chemical exfoliants to dissolve
the bonds between dead skin cells?
A. Hyaluronic acid
B. Alpha hydroxy acids (AHAs)
C. Dimethicone
D. Titanium dioxide
