Question 1Sanitation, Disinfection, and Safety

Under Alaska board rules, which item is classified as a single-use item that must be discarded after use on one client?

  1. A stainless steel tweezers
  2. A metal spatula used for wax
  3. A disposable eyebrow brush Correct answer.
  4. A reusable glass mixing bowl

Explanation

Single-use items are designed to be used on one client and then discarded; disposable applicators, brushes, and cotton swabs fall in this category. Tools made of durable materials that can be cleaned and disinfected are reusable.

Question 2Sanitation, Disinfection, and Safety

What is the correct first step when cleaning a metal esthetic implement after a service?

  1. Wash it with soap and warm water Correct answer.
  2. Soak it in disinfectant for ten hours
  3. Wipe it with a dry paper towel
  4. Place it in a sealed plastic bag

Explanation

Cleaning with soap and water removes debris, oil, and product residue before disinfection, because disinfectants cannot penetrate soil. Disinfection or sterilization follows cleaning, not the reverse.

Question 3Sanitation, Disinfection, and Safety

Which product is appropriate for disinfecting nonporous surfaces and reusable implements in an esthetics setting?

  1. An EPA-registered hospital-grade disinfectant Correct answer.
  2. A mild hand soap solution
  3. Plain distilled water
  4. Rubbing alcohol at 40 percent

Explanation

Disinfectants used in salons must be EPA-registered and labeled as hospital-grade or tuberculocidal for proper efficacy. Soap, water, and low-percentage alcohol do not meet the standard for disinfection.

Question 4Sanitation, Disinfection, and Safety

How should clean towels and linens be stored between clients?

  1. In a closed cabinet separate from soiled linens Correct answer.
  2. In an open bin near the sink
  3. Stacked on the treatment table
  4. In the same hamper as used linens

Explanation

Clean linens must be kept in a clean, closed storage area apart from soiled items to prevent cross-contamination. Mixing clean and dirty linens defeats the purpose of laundering.

Question 5Sanitation, Disinfection, and Safety

A client arrives with an inflamed, weeping cold sore on the lip. What is the appropriate action for an esthetician?

  1. Cover the sore with makeup and proceed
  2. Reschedule the service until the lesion heals Correct answer.
  3. Apply a numbing cream and continue
  4. Proceed with the facial but avoid the mouth area

Explanation

Active herpes lesions are contagious and a contraindication for facial services; the service should be postponed until healing. Working around the area still risks spread of the virus and irritation.

Question 6Sanitation, Disinfection, and Safety

Why should an esthetician avoid using a Credo blade or lancet on a client in most settings?

  1. These tools can cut or break the skin Correct answer.
  2. These tools cannot be cleaned
  3. These tools only work on dry skin
  4. These tools are illegal to own

Explanation

Tools that cut or penetrate the skin create a risk of injury and bloodborne pathogen exposure and are generally outside the esthetician scope. Estheticians should not perform procedures that break the skin unless specifically authorized.

Question 7Sanitation, Disinfection, and Safety

What is the primary purpose of wearing gloves during a waxing service?

  1. To protect both the client and the esthetician from pathogen transfer Correct answer.
  2. To reduce the amount of wax needed
  3. To keep the hands from feeling sticky
  4. To make the wax cool faster

Explanation

Gloves act as a barrier against microorganisms and product, protecting both parties. Gloves are not a convenience item for texture or temperature control.

Question 8Sanitation, Disinfection, and Safety

How should an esthetician dispose of a blood-soaked cotton pad after a minor nick during a service?

  1. Place it in the regular open trash can
  2. Put it in a lined, covered waste container Correct answer.
  3. Leave it on the counter for later
  4. Flush it down the toilet

Explanation

Items contaminated with blood should be placed in a lined container with a lid to prevent exposure to others. Leaving blood-contaminated waste in the open creates a hazard.

Question 9Sanitation, Disinfection, and Safety

Which practice best prevents cross-contamination between clients in a treatment room?

  1. Reusing the same towel for two clients
  2. Spraying disinfectant over used linens
  3. Changing linens and disinfecting the table between every client Correct answer.
  4. Wiping the table once at the end of the day

Explanation

Cross-contamination is prevented by cleaning and disinfecting surfaces and changing linens between each client. End-of-day cleaning alone leaves contamination between clients.

Question 10Sanitation, Disinfection, and Safety

What does the term "hospital-grade" on a disinfectant label indicate?

  1. The product is approved for killing a broad spectrum of pathogens Correct answer.
  2. The product is safe for hospital laundry
  3. The product is intended only for surgical instruments
  4. The product requires sterilization after use

Explanation

Hospital-grade disinfectants are EPA-registered to kill a broad range of disease-causing organisms, including tuberculosis bacteria. The term refers to efficacy, not to a specific use site or sterilization status.

Question 11Sanitation, Disinfection, and Safety

An esthetician uses a wooden spatula to remove wax from a pot for a client. What is the correct handling of that spatula?

  1. Store it in the wax pot for later
  2. Wash and reuse it for the next client
  3. Discard it after the single use Correct answer.
  4. Sanitize it with a dry cloth

Explanation

Wooden spatulas are porous and cannot be adequately disinfected, so they are treated as single-use and discarded. Double-dipping a used spatula also contaminates the wax pot.

Question 12Sanitation, Disinfection, and Safety

Which action most reduces the risk of spreading infection from the esthetician's hands?

  1. Using hand sanitizer only at day's end
  2. Wearing nail polish with chips
  3. Wearing rings during services
  4. Washing hands before and after each client Correct answer.

Explanation

Frequent handwashing before and after each client is the single most effective way to reduce transmission of microorganisms. Jewelry and chipped polish can harbor organisms and interfere with thorough cleaning.

Question 13Sanitation, Disinfection, and Safety

A bottle of disinfectant has been mixed and left in an open container for several days. What is the best practice?

  1. Use it until the bottle is empty
  2. Add water to restore the volume
  3. Discard it and mix a fresh solution Correct answer.
  4. Top it off with fresh concentrate

Explanation

Disinfectant solutions lose potency over time and when exposed to air and light, so they should be mixed fresh according to manufacturer directions and discarded when expired. Diluting or topping off alters the correct concentration.

Question 14Sanitation, Disinfection, and Safety

Which situation requires the esthetician to wear a fresh pair of gloves?

  1. When switching from one clean towel to another
  2. While writing client notes at the desk
  3. After touching a client's skin and before touching clean implements Correct answer.
  4. Moving from cleaning the sink to answering the phone

Explanation

Gloves must be changed whenever they become contaminated or when moving from a contaminated task to a clean one. Touching clean implements with soiled gloves cross-contaminates them.

Question 15Sanitation, Disinfection, and Safety

What is the difference between sanitation and disinfection?

  1. Disinfection only removes visible soil
  2. They are identical processes
  3. Sanitation reduces microorganisms; disinfection kills most pathogens on surfaces Correct answer.
  4. Sanitation kills all spores; disinfection kills some bacteria

Explanation

Sanitation lowers the number of microorganisms to a safer level, while disinfection destroys most pathogenic organisms on nonporous surfaces. Neither term means sterilization, which destroys all microorganisms including spores.

Question 16Sanitation, Disinfection, and Safety

An esthetician notices a crack in a plastic spatula used for product dispensing. What should be done?

  1. Rinse it and return it to the drawer
  2. Tape the crack and continue
  3. Continue using it until it breaks
  4. Discard it because cracks harbor microorganisms Correct answer.

Explanation

Cracks and crevices trap moisture, product, and microorganisms that cleaning cannot reach, so damaged implements must be discarded. Taping or continued use leaves a reservoir of contamination.

Question 17Sanitation, Disinfection, and Safety

Which is an appropriate way to store disinfected implements before use?

  1. In a basin of standing water
  2. In a pocket of the esthetician's apron
  3. In a drawer with soiled towels
  4. In a clean, covered container Correct answer.

Explanation

Disinfected implements should be stored clean and dry in a covered container to prevent recontamination. Contact with soiled items, clothing, or standing water reintroduces microorganisms.

Question 18Sanitation, Disinfection, and Safety

A client reports a known allergy to a product ingredient. What is the esthetician's best response?

  1. Apply the product to a small area to test
  2. Use the product at half strength
  3. Proceed because allergies are rare
  4. Avoid the ingredient and select an alternative Correct answer.

Explanation

Known allergies are a contraindication; the esthetician should avoid the allergen and choose a suitable alternative. Patch testing a known allergen risks a serious reaction.

Question 19Sanitation, Disinfection, and Safety

Why must an esthetician avoid double-dipping a wax applicator into the wax pot?

  1. It wastes wax
  2. It changes the wax color
  3. It contaminates the wax with client microorganisms Correct answer.
  4. It makes the wax too hot

Explanation

Reintroducing a used applicator transfers skin cells and microorganisms into the wax supply, which can then be passed to later clients. Using a fresh applicator or dispensing wax without returning it to the pot prevents this.

Question 20Sanitation, Disinfection, and Safety

Which document should an esthetician review before using a new disinfectant to confirm proper dilution and contact time?

  1. The salon appointment book
  2. A magazine article about salon trends
  3. The manufacturer's safety data sheet and label Correct answer.
  4. A client's intake form

Explanation

The safety data sheet and product label provide the manufacturer's directions for dilution, contact time, and safe handling. These instructions must be followed for the product to work as intended.

Question 21Sanitation, Disinfection, and Safety

An esthetician is exposed to a client's blood through a small cut on her hand. What is the appropriate immediate action?

  1. Cover the cut with a bandage and continue
  2. Wash the area with soap and water, then follow exposure-control procedures Correct answer.
  3. Apply disinfectant directly to the wound
  4. Ignore it because the cut is small

Explanation

After a blood exposure, the area should be washed thoroughly with soap and water and the incident reported according to the facility's exposure-control plan. Prompt reporting supports follow-up care and documentation.

Question 22Sanitation, Disinfection, and Safety

Which practice best demonstrates proper use of an autoclave for metal implements?

  1. Loading instruments wet and loosely covered
  2. Running a cycle once a week
  3. Placing items in sealed plastic bags before the cycle
  4. Following manufacturer parameters for time, temperature, and pressure Correct answer.

Explanation

Sterilization requires adherence to the manufacturer's specified time, temperature, and pressure, along with correct loading and monitoring. Improper loading or infrequent cycles compromises sterility.

Question 23Sanitation, Disinfection, and Safety

Why is a tuberculocidal claim on a disinfectant label important in an esthetics setting?

  1. It proves the product kills Mycobacterium tuberculosis, a hard-to-kill organism Correct answer.
  2. It indicates the product is fragrance-free
  3. It confirms the product sterilizes instruments
  4. It means the product is safe for skin contact

Explanation

Tuberculocidal efficacy demonstrates the disinfectant can kill a resistant organism, indicating a high level of antimicrobial activity. It does not mean the product is safe on skin or that it sterilizes.

Question 24Sanitation, Disinfection, and Safety

An esthetician must choose between two disinfectants: one labeled for a 10-minute contact time and one for 1 minute. Which consideration matters most?

  1. The longer time means the product is unsafe
  2. Contact time has no effect on efficacy
  3. The shorter time is always better for business
  4. The implement must remain wet for the full labeled contact time Correct answer.

Explanation

A disinfectant must stay wet on the surface for its labeled contact time to achieve the stated kill claim. Shortening the time, regardless of label, reduces efficacy.

Question 25Sanitation, Disinfection, and Safety

Which scenario most clearly violates infection-control standards in an esthetics practice?

  1. Using a fresh towel for each client
  2. Placing used tweezers directly into a drawer after a service Correct answer.
  3. Washing hands before and after each client
  4. Storing clean implements in a covered container

Explanation

Reusable implements must be cleaned and disinfected or sterilized before storage; placing used tweezers directly into a drawer contaminates the drawer and the next user. The other choices reflect proper practice.

Question 26Sanitation, Disinfection, and Safety

Under Oregon board rules, an esthetician's license must be posted in what manner at the place of business?

  1. Kept on file at home and shown only on request
  2. Carried in the esthetician's wallet at all times
  3. Displayed conspicuously in the salon where clients can see it Correct answer.
  4. Stored in the salon's locked office safe

Explanation

Licenses are public credentials and must be displayed conspicuously at the licensed establishment so clients and inspectors can verify them. Keeping a license stored away defeats that verification purpose.

Question 27Sanitation, Disinfection, and Safety

Which item is considered a single-use supply that must be discarded after one client?

  1. Stainless steel tweezers
  2. Glass mixing bowl
  3. Autoclavable metal comedone extractor
  4. Disposable mascara wand Correct answer.

Explanation

Single-use items are manufactured to be used once and cannot be reliably cleaned and disinfected for reuse. Porous or plastic disposable applicators such as mascara wands fall in this category.

Question 28Sanitation, Disinfection, and Safety

An esthetician is cleaning a metal extractor before disinfection. Which step order reflects correct implement processing?

  1. Scrub with soap and water, rinse and dry, then immerse in disinfectant for the labeled contact time Correct answer.
  2. Wipe with a dry towel, then store, then disinfect before the next client
  3. Soak in disinfectant, then scrub with soap, then store damp
  4. Disinfect first, then rinse, then scrub with soap

Explanation

Visible debris and residue must be removed by washing and drying before an implement contacts disinfectant, because soil reduces the disinfectant's effectiveness. The implement then soaks for the full labeled contact time.

Question 29Sanitation, Disinfection, and Safety

A client arrives with an inflamed, oozing rash on the treatment area. What is the esthetician's most appropriate action?

  1. Double the disinfectant strength used on the table afterward
  2. Postpone the service and refer the client to a physician Correct answer.
  3. Proceed but avoid the rash area entirely
  4. Apply a topical antiseptic and continue the service

Explanation

A suspicious, oozing, or inflamed skin condition is a contraindication because it may be infectious and service could worsen it. The safe response is to decline or postpone service and refer for medical evaluation.

Question 30Sanitation, Disinfection, and Safety

An esthetician wants to store a bottle of quats disinfectant that was mixed from concentrate this morning. Which practice best preserves its effectiveness?

  1. Pour it into an unlabeled spray bottle for convenience
  2. Top off the old solution with fresh concentrate each week
  3. Keep it in a labeled, closed container and use it within the manufacturer's stated use life Correct answer.
  4. Leave it in an open tray beside the sink

Explanation

Disinfectant solutions degrade over time and can be diluted by evaporation or contamination, so they must be stored closed and labeled and replaced within the manufacturer's stated use life. Unlabeled or open storage invites misuse and contamination.

Question 31Anatomy and Physiology

Which layer of the skin contains blood vessels, nerve endings, hair follicles, and sweat glands?

  1. Stratum basale
  2. Subcutaneous layer
  3. Dermis Correct answer.
  4. Stratum corneum

Explanation

The dermis is the middle layer and houses the vascular, nervous, and glandular structures of the skin. The epidermis is avascular and the subcutaneous layer is mostly adipose tissue.

Question 32Anatomy and Physiology

The outermost layer of the epidermis is called the:

  1. Stratum spinosum
  2. Stratum lucidum
  3. Stratum granulosum
  4. Stratum corneum Correct answer.

Explanation

The stratum corneum is the surface layer of flattened, keratinized dead cells that provides the skin's barrier. The other strata lie beneath it in the epidermis.

Question 33Anatomy and Physiology

Melanin, the pigment that gives skin its color and helps absorb ultraviolet radiation, is produced by which cells?

  1. Melanocytes Correct answer.
  2. Langerhans cells
  3. Fibroblasts
  4. Keratinocytes

Explanation

Melanocytes reside in the basal layer of the epidermis and synthesize melanin, which is transferred to surrounding keratinocytes. Keratinocytes form the barrier, Langerhans cells are immune cells, and fibroblasts build collagen in the dermis.

Question 34Anatomy and Physiology

Which vitamin is synthesized in the skin when it is exposed to ultraviolet light?

  1. Vitamin C
  2. Vitamin D Correct answer.
  3. Vitamin A
  4. Vitamin K

Explanation

Ultraviolet B light converts a cholesterol derivative in the skin into a vitamin D precursor that the body later activates. The other listed vitamins are obtained mainly through diet.

Question 35Anatomy and Physiology

The protein that gives the epidermis its strength and waterproofing quality is:

  1. Elastin
  2. Keratin Correct answer.
  3. Melanin
  4. Collagen

Explanation

Keratin is a tough fibrous protein produced by keratinocytes that hardens and waterproofs the outer skin. Collagen and elastin provide support and elasticity in the dermis, while melanin is a pigment.

Question 36Anatomy and Physiology

Sebum, the oily substance that lubricates skin and hair, is secreted by which glands?

  1. Ceruminous glands
  2. Eccrine glands
  3. Apocrine glands
  4. Sebaceous glands Correct answer.

Explanation

Sebaceous glands are attached to hair follicles and secrete sebum, which lubricates the skin and hair. Eccrine and apocrine glands produce sweat, and ceruminous glands produce earwax.

Question 37Anatomy and Physiology

The layer of skin that consists mainly of adipose tissue and provides insulation and cushioning is the:

  1. Subcutaneous layer Correct answer.
  2. Stratum basale
  3. Papillary dermis
  4. Reticular dermis

Explanation

The subcutaneous layer, also called the hypodermis, is composed largely of fat that insulates the body and cushions underlying structures. The dermal layers and stratum basale are higher in the skin and serve different functions.

Question 38Anatomy and Physiology

A client with dry, flaky skin is most likely to benefit from products that support the skin's barrier by mimicking which epidermal components?

  1. Keratin and sebum
  2. Collagen and elastin
  3. Ceramides and lipids Correct answer.
  4. Melanin and hemoglobin

Explanation

The epidermal barrier depends on lipids such as ceramides that hold corneocytes together and limit water loss. Replacing these lipids helps restore barrier function in dry skin. Melanin, keratin, collagen, and elastin serve other roles.

Question 39Anatomy and Physiology

The skin's acid mantle refers to the slightly acidic surface film that primarily functions to:

  1. Reduce sensation to touch
  2. Speed up collagen breakdown
  3. Increase melanin production
  4. Inhibit growth of harmful microorganisms Correct answer.

Explanation

The acid mantle is a slightly acidic film of sebum and sweat that discourages the growth of pathogenic bacteria and fungi. It does not affect pigmentation, collagen breakdown, or touch sensation.

Question 40Anatomy and Physiology

Which structure anchors the epidermis to the dermis and helps prevent them from separating?

  1. Basement membrane Correct answer.
  2. Papillary layer
  3. Dermal papilla
  4. Arrector pili muscle

Explanation

The basement membrane lies at the junction of the epidermis and dermis and provides adhesion between the two layers. The arrector pili muscle moves hair, and dermal papillae are projections that increase the interface area.

Question 41Anatomy and Physiology

A client wants to understand why their skin bruises easily after a minor bump. Which dermal function is most directly affected?

  1. Thermoregulation
  2. Vitamin D synthesis
  3. Sensory reception
  4. Structural support of blood vessels Correct answer.

Explanation

The dermis supports capillaries; when support tissue weakens, vessels rupture more easily and blood leaks into tissue, causing a bruise. Sensory reception, thermoregulation, and vitamin D synthesis do not directly explain bruising.

Question 42Anatomy and Physiology

Sweat glands that help regulate body temperature by releasing watery secretions directly onto the skin surface are called:

  1. Apocrine glands
  2. Eccrine glands Correct answer.
  3. Ceruminous glands
  4. Sebaceous glands

Explanation

Eccrine glands are distributed over most of the body and release watery sweat that cools the skin as it evaporates. Apocrine glands produce a thicker secretion, sebaceous glands produce oil, and ceruminous glands produce earwax.

Question 43Anatomy and Physiology

The arrector pili muscle is responsible for:

  1. Producing sebum
  2. Anchoring the nail plate
  3. Producing sweat
  4. Causing goose bumps by raising hair Correct answer.

Explanation

The arrector pili is a small smooth muscle attached to the hair follicle that contracts to raise the hair, producing goose bumps. Sebaceous glands produce sebum, sweat glands produce sweat, and the nail matrix anchors the nail.

Question 44Anatomy and Physiology

Which sensory receptors in the skin detect light touch and are located in the dermal papillae?

  1. Ruffini endings
  2. Krause end bulbs
  3. Meissner corpuscles Correct answer.
  4. Pacinian corpuscles

Explanation

Meissner corpuscles are located near the dermal-epidermal junction and detect light touch. Pacinian corpuscles detect deep pressure and vibration, while Ruffini endings detect sustained pressure and stretch.

Question 45Anatomy and Physiology

A client with a slow-healing wound asks why skin repair takes time. Which nutrient is most directly required for collagen synthesis during healing?

  1. Vitamin C Correct answer.
  2. Vitamin D
  3. Vitamin K
  4. Vitamin B12

Explanation

Vitamin C is a cofactor for the enzymes that cross-link and stabilize collagen, so deficiency delays wound healing. Vitamin D supports calcium absorption, vitamin K supports clotting, and B12 supports red blood cell formation.

Question 46Anatomy and Physiology

The nail plate is produced by which structure?

  1. Lunula
  2. Cuticle
  3. Nail matrix Correct answer.
  4. Nail bed

Explanation

The nail matrix is the tissue beneath the proximal nail that generates new nail cells, which harden to form the nail plate. The nail bed supports the plate, the cuticle is a protective fold, and the lunula is a visible part of the matrix.

Question 47Anatomy and Physiology

When a client's skin becomes red and warm after vigorous massage, which dermal response is primarily responsible?

  1. Increased keratin production
  2. Contraction of arrector pili muscles
  3. Increased melanin synthesis
  4. Vasodilation of dermal blood vessels Correct answer.

Explanation

Mechanical stimulation triggers vasodilation, increasing blood flow near the surface and producing warmth and redness. Melanin synthesis, arrector pili contraction, and keratin production do not cause immediate warmth and flushing.

Question 48Anatomy and Physiology

Which statement best describes the relationship between the epidermis and its blood supply?

  1. The epidermis obtains nutrients from sebum produced within its layers.
  2. The epidermis contains a rich capillary network throughout its layers.
  3. The epidermis is avascular and receives nutrients by diffusion from the dermis. Correct answer.
  4. The epidermis is supplied by arteries that pass through hair follicles.

Explanation

The epidermis has no blood vessels of its own; oxygen and nutrients diffuse from capillaries in the dermis. This limits the thickness of the epidermis and explains why deeper injuries bleed while superficial abrasions may not.

Question 49Anatomy and Physiology

The dermal papillae are important because they:

  1. Increase the surface area between the dermis and epidermis Correct answer.
  2. Secrete sweat during thermoregulation
  3. Produce sebum for the skin surface
  4. Contain melanocytes that color the skin

Explanation

Dermal papillae are fingerlike projections of the dermis that interlock with the epidermis, increasing the contact area for nutrient exchange and strengthening the bond between layers. They do not produce sebum, house melanocytes, or secrete sweat.

Question 50Anatomy and Physiology

A client's skin shows reduced elasticity and fine lines. Which dermal change most directly explains this?

  1. Thinning of the stratum corneum
  2. Loss of collagen and elastin fibers Correct answer.
  3. Decreased melanocyte activity
  4. Increased sebum production

Explanation

Elasticity and firmness depend on collagen and elastin in the dermis; their gradual loss reduces support and allows fine lines to form. Stratum corneum thinning, sebum changes, and melanocyte activity affect texture, oiliness, and color rather than elasticity.
