Question 1: Which of the following is the MOST effective method for destroying
bacterial spores on non-porous esthetic tools?
A. Sanitizing with an EPA-registered disinfectant spray
B. Immersing in 70% isopropyl alcohol for 10 minutes
C. Autoclaving using steam under pressure at 250°F for 15-20 minutes
D. Wiping with a quaternary ammonium compound solution
CORRECT ANSWER: C. Autoclaving using steam under pressure at 250°F for 15-20
minutes
Rationale: Autoclaving is the only method listed that achieves sterilization, which is
required to destroy bacterial spores. Sanitizing reduces microbes to safe levels but
does not kill spores; alcohol and quaternary ammonium compounds are disinfectants
effective against many pathogens but not spore-forming bacteria. State boards in TX,
CA, FL, and NY require sterilization of tools that penetrate the skin or contact blood.
Question 2: During a client consultation, an esthetician notices multiple small,
flesh-colored bumps with a central dimple on the client's chin. These lesions are
MOST likely:
A. Closed comedones
B. Milia
C. Molluscum contagiosum
D. Sebaceous hyperplasia
CORRECT ANSWER: C. Molluscum contagiosum
Rationale: Molluscum contagiosum presents as small, dome-shaped, flesh-colored
papules with a characteristic central umbilication (dimple). It is a viral infection caused
by a poxvirus and is contagious. Estheticians must recognize contraindications and
refer clients with infectious conditions to a dermatologist. Closed comedones lack the
central dimple; milia are keratin-filled cysts without umbilication; sebaceous
hyperplasia shows a central pore but is yellowish and soft.
,Question 3: According to universal precautions, when should an esthetician wear
disposable gloves during a facial service?
A. Only when performing extractions
B. Whenever there is potential contact with blood, bodily fluids, or non-intact skin
C. Only if the client has a known infectious disease
D. Gloves are not required for basic facial services
CORRECT ANSWER: B. Whenever there is potential contact with blood, bodily
fluids, or non-intact skin
Rationale: Universal precautions, mandated by OSHA and adopted by all state boards,
require gloves whenever exposure to blood, bodily fluids, mucous membranes, or non-
intact skin is anticipated. This protects both client and practitioner. Extractions often
involve micro-tears, but gloves are also needed for any service where barrier protection
is prudent, regardless of known client health status.
Question 4: Which layer of the epidermis is responsible for continuous cell division
and regeneration of the skin?
A. Stratum corneum
B. Stratum granulosum
C. Stratum spinosum
D. Stratum basale
CORRECT ANSWER: D. Stratum basale
Rationale: The stratum basale (germinativum) is the deepest epidermal layer where
keratinocytes undergo mitosis, continuously producing new cells that migrate upward.
The stratum corneum is the outermost protective layer of dead cells; stratum
granulosum contains keratohyalin granules; stratum spinosum provides strength and
flexibility but is not the primary site of cell division.
Question 5: In California, an esthetician license must be renewed every:
A. 1 year
B. 2 years
C. 3 years
D. 4 years
CORRECT ANSWER: B. 2 years
Rationale: California esthetician licenses expire every two years and must be renewed
through the Board of Barbering and Cosmetology. While California does not currently
require continuing education for renewal, timely submission of the renewal application
and fee is mandatory to avoid late penalties or license expiration. Other states may have
different renewal cycles.
Question 6: Which ingredient is commonly used in chemical peels to exfoliate by
breaking down desmosomes between corneocytes?
,A. Hyaluronic acid
B. Salicylic acid
C. Glycolic acid
D. Niacinamide
CORRECT ANSWER: C. Glycolic acid
Rationale: Glycolic acid, an alpha-hydroxy acid (AHA), works by weakening the bonds
(desmosomes) that hold dead skin cells together in the stratum corneum, promoting
exfoliation. Salicylic acid (a BHA) is lipid-soluble and penetrates oil-filled pores;
hyaluronic acid is a humectant; niacinamide is an anti-inflammatory and barrier-
support ingredient. Estheticians must understand ingredient mechanisms to select
appropriate treatments.
Question 7: What is the PRIMARY purpose of performing a patch test 24-48 hours
before a chemical peel or new product application?
A. To determine the client's skin type
B. To assess the client's pain tolerance
C. To identify potential allergic reactions or sensitivity
D. To evaluate product absorption rate
CORRECT ANSWER: C. To identify potential allergic reactions or sensitivity
Rationale: Patch testing is a critical safety protocol to detect hypersensitivity or allergic
contact dermatitis before full application. This prevents adverse reactions that could
cause injury, liability, or client harm. Skin typing is done via consultation and visual
analysis; pain tolerance and absorption are not primary patch test objectives.
Question 8: Which muscle is primarily responsible for elevating the corners of the
mouth during a smile?
A. Orbicularis oris
B. Zygomaticus major
C. Buccinator
D. Masseter
CORRECT ANSWER: B. Zygomaticus major
Rationale: The zygomaticus major originates at the zygomatic bone and inserts at the
corner of the mouth, pulling it upward and laterally to produce smiling. Orbicularis oris
encircles the mouth for pursing; buccinator compresses the cheek for chewing;
masseter elevates the mandible for mastication. Knowledge of facial musculature
informs massage techniques and treatment planning.
Question 9: In Texas, what is the MINIMUM number of training hours required to
qualify for the esthetician licensing examination?
A. 300 hours
B. 600 hours
, C. 750 hours
D. 1,000 hours
CORRECT ANSWER: C. 750 hours
Rationale: Texas requires completion of 750 hours in a TDLR-approved esthetician
program before sitting for the licensing exam. This includes theory and practical
instruction in sanitation, skin care, facials, hair removal, and state laws. Requirements
vary by state: CA requires 600 hours, FL requires 220-260 hours, NY requires 600 hours.
Question 10: Which condition is a CONTRAINDICATION for performing facial
massage?
A. Dry skin
B. Rosacea in the inflammatory stage
C. Mild acne vulgaris
D. Hyperpigmentation
CORRECT ANSWER: B. Rosacea in the inflammatory stage
Rationale: During active inflammation, rosacea presents with erythema, papules, and
telangiectasia; massage can exacerbate vascular dilation and irritation. Estheticians
should avoid stimulating treatments during inflammatory phases and refer to a
dermatologist. Dry skin, mild acne, and hyperpigmentation may be treated with
appropriate protocols and product selection.
Question 11: What is the correct sequence for donning personal protective
equipment (PPE) before a service involving potential fluid exposure?
A. Gloves, gown, mask, eye protection
B. Gown, mask, eye protection, gloves
C. Mask, gown, gloves, eye protection
D. Eye protection, gloves, gown, mask
CORRECT ANSWER: B. Gown, mask, eye protection, gloves
Rationale: CDC guidelines specify donning order: gown first to cover clothing, then
mask/respirator, eye protection, and gloves last to ensure cuffs are covered. This
sequence minimizes contamination risk. Removing PPE follows reverse order with
careful technique to avoid self-contamination. Estheticians must follow infection
control protocols per OSHA and state regulations.
Question 12: Which type of light therapy is MOST appropriate for targeting
Propionibacterium acnes in acne treatment?
A. Red light (630-660 nm)
B. Blue light (415-420 nm)
C. Infrared light (800+ nm)
D. Ultraviolet B (UVB)
