Domain 1: Sanitation and Sterilization (25 Questions)
Q1: A manicurist finishes a service and needs to disinfect metal cuticle nippers.
According to Texas TDLR regulations, what is the correct procedure?
A. Wipe with alcohol and place in a UV sterilizer for 2 minutes
B. Clean with soap and water, dry, then immerse in EPA-registered hospital-level
disinfectant for the labeled contact time [CORRECT]
C. Spray with disinfectant and let air dry for 5 minutes
D. Soak in Barbicide for 2 minutes, then rinse and store in an open container
Correct Answer: B
Rationale: Texas TDLR requires multi-use implements to be cleaned with soap and
water first to remove debris, then dried before immersion in an EPA-registered
hospital-level disinfectant (bactericidal, virucidal, fungicidal) for the full labeled contact
time (typically 10 minutes). Option A is incorrect because alcohol is an antiseptic for
skin, not a disinfectant for implements, and UV sterilizers are not approved for TDLR
compliance. Option C fails because spraying does not provide complete immersion or
adequate contact time. Option D is incorrect because 2 minutes is insufficient contact
time (Barbicide requires 10 minutes), and implements must be stored in clean, covered,
dry containers, not open ones.
,Q2: A client accidentally cuts their finger during a manicure, resulting in bleeding. What
is the FIRST action the manicurist must take?
A. Continue the service while wearing gloves to avoid interruption
B. Immediately stop the service and apply pressure with clean gauze to the wound
[CORRECT]
C. Clean the area with hydrogen peroxide and continue filing
D. Disinfect the workstation while the client holds their own finger
Correct Answer: B
Rationale: Blood exposure requires immediate cessation of service to prevent further
injury and potential pathogen transmission. The first step is always to control bleeding
by applying pressure with clean gauze. Texas TDLR mandates standard
precautions—treating all blood as potentially infectious. Option A violates infection
control protocols and risks cross-contamination. Option C is incorrect because
hydrogen peroxide is for first aid only and damages tissue; it should not be used for
routine nail service procedures. Option D delays proper first aid and neglects the client's
immediate need.
Q3: Which level of decontamination is required for implements that penetrate the skin,
such as cuticle nippers used to remove hangnails?
A. Sanitization with soap and water
B. Disinfection with EPA-registered hospital-level disinfectant
C. Sterilization using autoclave, dry heat, or chemical sterilants [CORRECT]
D. Antiseptic treatment with 70% alcohol
Correct Answer: C
Rationale: Sterilization—the destruction of ALL microorganisms including bacterial
spores—is required for implements that penetrate skin or contact blood. Texas TDLR
,recognizes autoclave (steam under pressure), dry heat sterilization, or high-level
chemical sterilants like glutaraldehyde with extended contact times as appropriate
methods. Sanitization (A) only reduces microorganisms to safe levels for surfaces.
Disinfection (B) eliminates most pathogens but not spores, making it suitable only for
non-porous implements that do not penetrate skin. Antiseptics (D) are for skin
application only and do not sterilize implements.
Q4: At the end of the workday, a manicurist must clean a whirlpool/jetted foot spa. What
is the required procedure according to Texas TDLR?
A. Drain water, wipe surfaces, and refill with fresh water for the next day
B. Drain water, clean with soap/water, circulate EPA-registered disinfectant through jets
for the labeled contact time, drain, rinse, and dry [CORRECT]
C. Add bleach to the water and let it sit overnight
D. Wipe the basin with disinfectant wipes and cover with a towel
Correct Answer: B
Rationale: Texas TDLR specifically requires whirlpool/jetted foot spas to have
disinfectant circulated through the entire system—including jets—to eliminate biofilm
and pathogens that accumulate in plumbing lines. The procedure must include draining,
cleaning surfaces, circulating EPA-registered disinfectant for the full contact time
(typically 10 minutes), then draining, rinsing, and drying. Option A misses critical
disinfection and biofilm removal. Option C uses bleach, which is corrosive to equipment
and not specified as a TDLR-approved method. Option D fails to address the internal jet
system where bacteria proliferate.
Q5: A manicurist notices the disinfectant solution in the implement jar appears cloudy
and contains visible debris. What should she do?
, A. Add fresh disinfectant to top off the solution
B. Change the solution immediately, even if it is before the scheduled daily change time
[CORRECT]
C. Remove visible debris with tongs and continue using the solution
D. Test the concentration with test strips and adjust if needed
Correct Answer: B
Rationale: Texas TDLR requires disinfectant solutions to be changed immediately when
visibly soiled, regardless of the scheduled change time (typically daily). Visible debris
and cloudiness indicate the solution has been compromised and cannot effectively
disinfect implements. Option A dilutes the solution without removing contamination.
Option C does not address the compromised chemical efficacy. Option D is insufficient
because test strips check concentration but cannot restore effectiveness once organic
load has depleted the solution's active ingredients.
Q6: Which of the following is classified as a single-use implement that must be
discarded after one client?
A. Metal nail file
B. Glass nail file
C. Wooden orange stick [CORRECT]
D. Stainless steel cuticle pusher
Correct Answer: C
Rationale: Wooden orange sticks are porous, cannot be properly disinfected, and are
classified as single-use implements under Texas TDLR regulations. They must be
discarded immediately after use on one client in a covered trash receptacle. Metal files
(A), glass files (B), and stainless steel pushers (D) are non-porous, multi-use implements
that can be cleaned and disinfected between clients according to TDLR protocols.
