Guaranteed – A+ Graded
Section A: Sanitation, Disinfection, Sterilization & Infection
Control (20 Questions)
Q1: A client arrives for a facial treatment. The esthetician notices that the facial brushes
from the previous client are still on the counter, visibly soiled with product residue.
Before placing these implements in disinfectant solution, which step must be
completed first?
A. Immediately submerge the brushes in EPA-registered disinfectant for 10 minutes
B. Thoroughly clean the brushes to remove all visible debris, oil, and product residue
before disinfection
C. Spray the brushes with 70% alcohol and place them in a UV sterilizer
D. Wrap the brushes in a clean towel and set aside for the end-of-day cleaning cycle
Correct Answer: B
,Rationale: Implements must be thoroughly cleaned BEFORE being soaked in
disinfectant. Organic matter (oil, product, debris) inactivates disinfectant chemicals and
prevents proper contact with microorganisms. Cleaning removes visible soil;
disinfection destroys harmful organisms on cleaned surfaces. Option A skips the
essential cleaning step; Option C uses alcohol which is not an EPA-registered
disinfectant for implements; Option D delays proper processing and risks
cross-contamination.
Q2: An esthetician is selecting a disinfectant for metal implements such as tweezers
and extractors. Which solution is considered safe and effective for this purpose when
used at the correct concentration?
A. 70% isopropyl alcohol
B. Household bleach diluted 1:10
C. Phenols in a 5% solution
D. Formalin tablets dissolved in water
Correct Answer: C
Rationale: Phenols in a 5% solution are safe and effective for disinfecting metal
implements. They are EPA-registered and provide broad-spectrum antimicrobial activity.
Option A (alcohol) evaporates too quickly and is not EPA-registered for implement
disinfection; Option B (bleach) is corrosive to metal and no longer widely recommended
,for salon use; Option D (formalin) is no longer considered safe for salon use due to
toxicity concerns.
Q3: A spa owner is reviewing disinfectant protocols with staff. How frequently must
EPA-registered disinfecting soak solutions be changed according to standard practice?
A. After each client
B. Once per shift
C. Once daily
D. Once weekly
Correct Answer: C
Rationale: EPA-registered disinfecting soak solutions must be changed once daily (or
sooner if visibly contaminated or diluted). This ensures maintained efficacy throughout
the workday. Solutions become contaminated with organic matter and lose potency
over time. Option A is impractical and unnecessary; Option B may be insufficient for
high-volume spas; Option D allows excessive contamination and reduced efficacy.
Q4: A new esthetician asks why bleach and alcohol are no longer widely used as
disinfectants in the spa setting. Which explanation is most accurate?
, A. They are too expensive compared to modern alternatives
B. They have been proven completely ineffective against all microorganisms
C. They have limitations including corrosion, rapid evaporation, lack of EPA registration
for salon implements, and safety concerns
D. They are only effective against bacteria, not viruses or fungi
Correct Answer: C
Rationale: Bleach and alcohol are no longer widely used as primary salon disinfectants
due to multiple limitations: bleach is corrosive to metals and irritating to skin; alcohol
evaporates too quickly to maintain required contact time; neither is EPA-registered for
implement disinfection in salon settings; and both present safety concerns. Modern
EPA-registered disinfectants are preferred. Option A is incorrect; Option B is false (they
have limited efficacy); Option D is partially true but not the primary reason for disuse.
Q5: A spa receives a shipment of new chemical peels. Which federal agency requires
that the spa maintain Material Safety Data Sheets (MSDS/SDS) for every product used?
A. EPA (Environmental Protection Agency)
B. FDA (Food and Drug Administration)
C. OSHA (Occupational Safety and Health Administration)
