Question 1Safety, Sanitation, and Infection Control

A practitioner is about to begin a facial. What is the minimum time hands should be lathered with soap and water during routine handwashing?

  1. 20 seconds Correct answer.
  2. 10 seconds
  3. 2 minutes
  4. 5 seconds

Explanation

Routine handwashing should last at least 20 seconds, with soap worked over the palms, backs of hands, between fingers, and under nails. This contact time helps physically remove transient microorganisms.

Question 2Safety, Sanitation, and Infection Control

Which type of disinfectant is required for reusable esthetic implements in Arizona?

  1. Diluted household bleach
  2. 70% isopropyl alcohol
  3. Antibacterial soap
  4. EPA-registered hospital-grade disinfectant Correct answer.

Explanation

Reusable implements must be cleaned and then disinfected with an EPA-registered hospital-grade disinfectant used according to its label directions. The label contact time must be followed for the product to work as intended.

Question 3Safety, Sanitation, and Infection Control

Which item must be discarded after a single client?

  1. Glass mixing bowl
  2. Reusable wax warmer
  3. Stainless steel extraction tool
  4. Wooden wax applicator Correct answer.

Explanation

Wooden applicators are porous and cannot be reliably cleaned and disinfected, so they are treated as single-use. Reusable metal and glass items can be cleaned and disinfected if they are nonporous and intact.

Question 4Safety, Sanitation, and Infection Control

What does sanitizing accomplish?

  1. It destroys all bacterial spores
  2. It removes all dirt and kills all viruses
  3. It reduces the number of microorganisms on a surface to a safe level Correct answer.
  4. It sterilizes implements for surgery

Explanation

Sanitizing lowers the microbial count on a surface to a safer level, usually through cleaning with soap or detergent. It is a lower level of microbial control than disinfection or sterilization.

Question 5Safety, Sanitation, and Infection Control

A metal spatula has been used to remove product from a jar. What is the correct processing before it is reused on another client?

  1. Wipe it with a dry towel and return it to the drawer
  2. Clean it with soap and water, dry it, then immerse it in hospital-grade disinfectant for the labeled contact time Correct answer.
  3. Rinse it under warm water only
  4. Spray it with air freshener and store it

Explanation

Reusable implements must first be cleaned to remove product and debris, then disinfected with an EPA-registered hospital-grade product for the full label contact time. Cleaning before disinfection allows the disinfectant to reach the surface.

Question 6Safety, Sanitation, and Infection Control

During a waxing service, how should wax be applied?

  1. Return unused wax from the client back to the pot
  2. Dip the same applicator repeatedly if the wax is hot enough
  3. Use fingers after sanitizing them
  4. Use a new single-use applicator each time wax is removed from the pot Correct answer.

Explanation

Double dipping can introduce skin cells, blood, and microorganisms into the wax pot. A fresh single-use applicator each time prevents contamination of the remaining wax.

Question 7Safety, Sanitation, and Infection Control

How should clean towels and linens be stored?

  1. In a closed cabinet separate from soiled linens Correct answer.
  2. In the same hamper as used capes
  3. On the floor under the sink
  4. In an open bin next to dirty linens

Explanation

Clean linens must be kept in a clean, closed storage area away from soiled items to prevent cross-contamination. Separation from dirty laundry is a basic infection-control practice.

Question 8Safety, Sanitation, and Infection Control

Where should a used razor blade be placed?

  1. In a rigid, puncture-resistant sharps container Correct answer.
  2. In a plastic bag in the service drawer
  3. In the laundry hamper
  4. In the regular trash wrapped in tissue

Explanation

Sharp items must go into a rigid, puncture-resistant sharps container to prevent injury and exposure to bloodborne pathogens. Ordinary trash and fabric hampers do not provide adequate protection.

Question 9Safety, Sanitation, and Infection Control

What is the correct way to remove cream from a large container for a client?

  1. Use fingertips after sanitizing them
  2. Use the client's fingers
  3. Use a clean spatula and avoid touching the remaining product Correct answer.
  4. Blow on the product to loosen it

Explanation

A clean spatula limits contamination of the bulk product. Touching the remaining product with fingers or a used tool can introduce microorganisms into the container.

Question 10Safety, Sanitation, and Infection Control

When should gloves be changed during a service?

  1. Only before waxing
  2. At the end of the day
  3. Between clients and whenever torn or contaminated Correct answer.
  4. Only when visibly soiled

Explanation

Gloves are changed between clients and any time they are torn, punctured, or contaminated. Hand hygiene is performed after glove removal.

Question 11Safety, Sanitation, and Infection Control

A client arrives for a facial with an active cold sore on the lip. What should the esthetician do?

  1. Pop the blister and disinfect it
  2. Apply makeup over it
  3. Postpone the service and refer the client to a physician Correct answer.
  4. Proceed but avoid the lip

Explanation

An active cold sore is a contagious herpes simplex lesion. The service should be postponed, and the client should be referred for medical evaluation rather than treated over or near the lesion.

Question 12Safety, Sanitation, and Infection Control

Hand sanitizer may be used in place of handwashing in which situation?

  1. After using the restroom
  2. Before eating
  3. Never; it does not replace soap and water for routine hand hygiene Correct answer.
  4. When hands are visibly soiled

Explanation

Hand sanitizer is an adjunct to hand hygiene, not a replacement for soap and water. Soap and water are required after restroom use, before eating, and whenever hands are visibly soiled.

Question 13Safety, Sanitation, and Infection Control

A pair of tweezers falls on the floor during a service. What must happen before it is used again?

  1. Set it aside until the end of the day
  2. Rinse it with water
  3. Wipe it with alcohol and continue
  4. Clean and disinfect it with an EPA-registered hospital-grade disinfectant Correct answer.

Explanation

An implement that contacts the floor is contaminated and must be cleaned and disinfected before reuse. A quick wipe or rinse does not meet the cleaning and disinfection requirement.

Question 14Safety, Sanitation, and Infection Control

When must a treatment table be cleaned and disinfected?

  1. Weekly
  2. Once daily
  3. Only when visibly soiled
  4. Before and after each client Correct answer.

Explanation

Treatment surfaces are cleaned and disinfected before and after each client to prevent transfer of microorganisms between clients. Visible soil is not required for disinfection to be necessary.

Question 15Safety, Sanitation, and Infection Control

Why are porous items such as foam sponges and wooden sticks usually treated as single-use?

  1. They melt in disinfectant
  2. Disinfectants cannot reliably penetrate porous surfaces Correct answer.
  3. They are too expensive to clean
  4. They are banned by the EPA

Explanation

Porous materials can trap microorganisms below the surface where disinfectants may not reach. Because reliable disinfection cannot be assured, such items are used once and discarded.

Question 16Safety, Sanitation, and Infection Control

A client's skin bleeds during an extraction. What is the correct first response?

  1. Stop the service, put on gloves, and clean the area with an EPA-registered hospital-grade disinfectant labeled for bloodborne pathogens Correct answer.
  2. Spray perfume on the area
  3. Rinse the area with hot water and resume
  4. Blot with a towel and continue the facial

Explanation

Blood exposure requires stopping the service, protecting the practitioner with gloves, and following bloodborne-pathogen cleanup procedures. The area and any contaminated items must be handled with a hospital-grade disinfectant with the appropriate label claim.

Question 17Safety, Sanitation, and Infection Control

What is required for capes and neck strips between clients?

  1. Spray the cape with water
  2. Use a clean cape and a fresh disposable neck strip for each client
  3. Turn the cape inside out and reuse it Correct answer.
  4. Use the same cape for all clients and brush it off

Explanation

Capes and neck strips contact the client's skin and hair, so a clean cape and a fresh neck strip are used for each client. Reusing soiled linens can transfer microorganisms.

Question 18Safety, Sanitation, and Infection Control

What is the role of a UV sterilizer cabinet in an esthetician's sanitation routine?

  1. It may be used only after implements have been cleaned and disinfected; it is not a substitute Correct answer.
  2. It sterilizes all porous items
  3. It is required for all metal tools
  4. It replaces cleaning and disinfection

Explanation

UV cabinets are not a reliable substitute for cleaning and hospital-grade disinfection. They may be used only as an additional storage or holding measure after proper processing.

Question 19Safety, Sanitation, and Infection Control

After extractions, how should reusable metal extraction tools be processed?

  1. Place in a UV cabinet only
  2. Wipe with a disinfecting wipe and store
  3. Soak in water
  4. Clean, then disinfect with hospital-grade disinfectant for the labeled contact time Correct answer.

Explanation

Tools contaminated with skin oil, blood, or debris must be cleaned before disinfection so the disinfectant can contact the surface. The hospital-grade disinfectant must be used for its full label contact time.

Question 20Safety, Sanitation, and Infection Control

Which statement about autoclave sterilization is accurate?

  1. It is a type of sanitizer for countertops
  2. It uses steam under pressure and is suitable only for items that can withstand heat and moisture Correct answer.
  3. It can sterilize lotion bottles and powders
  4. It uses UV light to kill bacteria

Explanation

An autoclave sterilizes with steam under pressure, destroying all microbial life including spores. It is limited to items that can tolerate high heat and moisture.

Question 21Safety, Sanitation, and Infection Control

Why must safety data sheets (SDS) be kept for salon products?

  1. To prove the product is EPA-registered
  2. To replace the need for labels
  3. To advertise product ingredients to clients
  4. To provide hazard, handling, and emergency information Correct answer.

Explanation

Safety data sheets provide information about hazards, safe handling, storage, and emergency measures for chemical products. They support workplace safety and hazard communication.

Question 22Safety, Sanitation, and Infection Control

A reusable glass mixing bowl is used to mix a mask. What should be done between clients?

  1. Wipe with a dry paper towel
  2. Wash with soap and water, then disinfect Correct answer.
  3. Place in the freezer
  4. Rinse with water and air dry

Explanation

Reusable bowls must be washed to remove product residue and then disinfected with an appropriate hospital-grade product. Rinsing or dry wiping alone does not disinfect.

Question 23Safety, Sanitation, and Infection Control

Which statement correctly distinguishes disinfection from sterilization?

  1. Disinfection destroys most pathogenic microorganisms, while sterilization destroys all microbial life including spores Correct answer.
  2. Disinfection and sterilization are the same process
  3. Sterilization is used only on the floor
  4. Disinfection kills all spores, while sterilization only reduces bacteria

Explanation

Disinfection destroys most pathogenic microorganisms on inanimate surfaces but may not kill all spores. Sterilization destroys all microbial life, including bacterial spores.

Question 24Safety, Sanitation, and Infection Control

Where is eating and drinking permitted in a salon?

  1. At the treatment station between clients
  2. Next to the wax warmer
  3. In a designated break area away from service areas Correct answer.
  4. At the reception desk while servicing a client

Explanation

Eating and drinking are confined to designated break areas away from service and product areas. This reduces contamination of equipment, supplies, and treatment surfaces.

Question 25Safety, Sanitation, and Infection Control

A clean towel falls onto the floor. What should the esthetician do?

  1. Shake it out and use it
  2. Use it only on the floor
  3. Spray it with sanitizer and use it
  4. Place it in the soiled linen container and use a fresh towel Correct answer.

Explanation

A towel that contacts the floor is considered soiled and must not be used on a client. It belongs in the soiled linen container, and a fresh towel should be used instead.

Question 26Safety, Sanitation, and Infection Control

What is the minimum length of time hands should be washed with soap and water in a salon setting?

  1. At least 5 seconds
  2. At least 3 minutes
  3. Until the hands feel dry
  4. At least 20 seconds Correct answer.

Explanation

Handwashing should last at least 20 seconds and cover the palms, backs of the hands, between the fingers, and under the nails. That duration allows soap and friction to lift and rinse away transient microorganisms picked up from clients and surfaces.

Question 27Safety, Sanitation, and Infection Control

An esthetician sees that the power cord on a facial steamer is frayed and the inner wires are exposed. What is the correct action?

  1. Wrap the cord with tape and keep using it
  2. Lay the cord under a towel so it stays dry
  3. Use the steamer only on the lowest heat setting
  4. Take the steamer out of service until repaired Correct answer.

Explanation

Any damaged cord is a shock and fire hazard and the equipment must be withdrawn from use until it is properly repaired or replaced. Tape, lower settings, and covering the cord do not restore the insulation or remove the hazard.

Question 28Safety, Sanitation, and Infection Control

Which item of personal protective equipment should be worn when mixing chemical peels or other strong solutions?

  1. Safety glasses or goggles Correct answer.
  2. A cloth apron over the uniform
  3. Disposable ear plugs
  4. Sterile surgical gloves

Explanation

Eye protection is required whenever there is a risk of splashing acids, alkalis, or other irritating chemicals into the eyes. Sterile gloves are not needed for mixing, and a cloth apron does not protect the face.

Question 29Safety, Sanitation, and Infection Control

How should a bottle of disinfectant concentrate be stored between uses?

  1. Beside food items in the staff refrigerator
  2. In any clean, unmarked spray bottle
  3. In a clear drinking glass with a lid
  4. In the original labeled container, tightly closed Correct answer.

Explanation

Products must be kept in their original containers with the manufacturer's label intact so that ingredients, hazards, and first-aid directions stay with the product. Labels also prevent dangerous mix-ups and satisfy workplace chemical-safety requirements.

Question 30Safety, Sanitation, and Infection Control

A hospital-grade disinfectant label states a 10-minute contact time. What does this mean in practice?

  1. Tools stay wet with it for 10 minutes Correct answer.
  2. Tools are wiped dry and put away after ten minutes
  3. The solution can be reused for 10 minutes before it expires
  4. The disinfectant must be rinsed off with water at ten minutes

Explanation

Contact time, or dwell time, is the period an item must remain fully wet with the diluted disinfectant for the label's kill claims to be valid. Removing the item early or letting it dry shortens the exposure and leaves pathogens alive.

Question 31Safety, Sanitation, and Infection Control

Which label information confirms that a product is an EPA-registered hospital-grade disinfectant?

  1. A lot number and expiration date
  2. An EPA registration number Correct answer.
  3. A cosmetic ingredient list
  4. A cruelty-free bunny seal

Explanation

Disinfectants used on surfaces and implements must carry an EPA registration number and a label listing the organisms the product is proven to kill. That registration is what distinguishes a true disinfectant from a general cleaner or cosmetic product.

Question 32Safety, Sanitation, and Infection Control

During a facial, an esthetician needs a second scoop of cream after the spatula has touched the client's skin. What is the correct practice?

  1. Add alcohol to the jar first to sanitize the product
  2. Use freshly washed fingertips to scoop it out
  3. Dip the same spatula back in quickly
  4. Use a fresh clean spatula for the second scoop Correct answer.

Explanation

Re-dipping a contaminated spatula carries client material into the container and contaminates the entire product. A new clean spatula, or product already dispensed onto a clean surface, keeps the bulk supply free of contamination.

Question 33Safety, Sanitation, and Infection Control

Before a reusable metal implement is placed in disinfectant, what must be done with it?

  1. It should be left in a drawer overnight first
  2. It should be heated with a hot towel
  3. It must be washed with soap and water to remove residue Correct answer.
  4. It can go straight into the disinfectant from the tray

Explanation

Cleaning with soap and water removes organic soil such as oil, skin cells, and product residue that can shield or inactivate the disinfectant. Disinfection is only effective on an item that has already been thoroughly cleaned.

Question 34Safety, Sanitation, and Infection Control

An esthetician has a small, uncovered cut on one finger. What should be done before performing a facial?

  1. Wipe the finger with alcohol and skip gloves
  2. Bandage the cut and wear a glove over that hand Correct answer.
  3. Apply lotion and proceed without covering it
  4. Tape a tissue loosely over the cut

Explanation

Open lesions must be completely covered so that the esthetician's blood does not contact the client and the esthetician is not exposed to client fluids. A bandage plus a glove provides a sealed barrier; either one alone is insufficient.

Question 35Safety, Sanitation, and Infection Control

A client arrives for a lash service with red, itchy, crusty eyes and visible discharge. What is the appropriate response?

  1. Proceed but use extra sanitizer afterward
  2. Work only on the eye that looks normal
  3. Postpone the service and refer the client to a physician Correct answer.
  4. Wear a mask and continue the appointment

Explanation

Redness with crusting and discharge suggests a contagious eye infection such as conjunctivitis, which is a contraindication for eye-area services. The service should be postponed and the client referred for medical evaluation to avoid spreading infection and harming the eye.

Question 36Safety, Sanitation, and Infection Control

What should be done before a brow or lash tint is applied for the first time?

  1. Have the client sign a waiver instead
  2. Perform a patch test 24 to 48 hours ahead Correct answer.
  3. Dilute the tint with water before use
  4. Nothing, because tints are considered hypoallergenic

Explanation

Tints contain dyes that can trigger allergic reactions, including delayed hypersensitivity, so a patch test is performed 24 to 48 hours before the first application. The client is checked for redness or swelling before the service proceeds.

Question 37Safety, Sanitation, and Infection Control

How should clean, disinfected implements such as tweezers be kept between clients?

  1. In a cloth pouch shared by all tools
  2. In a drawer with used linens
  3. In a clean covered container for disinfected tools Correct answer.
  4. Loose in the esthetician's apron pocket

Explanation

Disinfected implements must be protected from dust, spills, and contact with soiled items, which a clean covered container provides. Storing them loosely or with used items recontaminates them and undoes the disinfection step.

Question 38Safety, Sanitation, and Infection Control

A drop of a client's blood splashes into the esthetician's eye. What should she do first?

  1. Put antibiotic eye drops from the salon kit in the eye
  2. Flush the eye with clean water for about 15 minutes Correct answer.
  3. Finish the service first, then rinse at the end of the shift
  4. Wipe the eye with a disinfectant wipe

Explanation

A mucous-membrane exposure requires immediate flushing with water or saline for about 15 minutes to reduce the dose of infectious material. The incident is then reported and the employee is sent for confidential medical evaluation and follow-up.

Question 39Safety, Sanitation, and Infection Control

Under bloodborne pathogens regulations, what must an employer make available to employees whose duties involve exposure risk?

  1. Hepatitis B vaccine at no cost, offered within 10 working days of assignment Correct answer.
  2. A cash bonus each year in place of any vaccination coverage
  3. A signed waiver that removes all liability from the salon for exposure
  4. Vaccination only after an exposure incident has occurred

Explanation

The bloodborne pathogens standard requires the employer to offer the hepatitis B vaccination series free of charge within 10 working days of initial assignment. Employees may decline in writing, but the offer must be made and documented.

Question 40Safety, Sanitation, and Infection Control

A written exposure control plan in a salon must include which element?

  1. The esthetician's personal medical history
  2. Procedures for evaluating and following up on exposure incidents Correct answer.
  3. Monthly sales records for disinfection supplies
  4. A list of clients with past blood exposures

Explanation

An exposure control plan documents how the salon identifies exposure risk, the precautions and controls used, and the post-exposure evaluation and follow-up process. It is a workplace safety document and must be reviewed and updated regularly.

Question 41Skin Sciences: Anatomy, Physiology, and Histology

Which layer of the epidermis contains the dividing stem cells that continuously renew the skin?

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

Explanation

Mitosis occurs in the deepest epidermal layer, the stratum basale, and daughter cells migrate toward the surface as they mature. The more superficial layers contain progressively more differentiated cells.

Question 42Skin Sciences: Anatomy, Physiology, and Histology

What is the principal role of the stratum corneum?

  1. To generate new keratinocytes
  2. To anchor hair follicles
  3. To produce melanin pigment
  4. To waterproof and protect the skin Correct answer.

Explanation

The stratum corneum is made of flattened corneocytes surrounded by lipids, forming the skin's main barrier against water loss and external irritants. It is the outermost epidermal layer.

Question 43Skin Sciences: Anatomy, Physiology, and Histology

Which epidermal cells synthesize melanin?

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

Explanation

Melanocytes reside mainly in the stratum basale and produce melanin, which is transferred to nearby keratinocytes to help protect against UV radiation.

Question 44Skin Sciences: Anatomy, Physiology, and Histology

The subcutaneous layer consists mainly of:

  1. Keratinized epithelial cells
  2. Elastic cartilage
  3. Dense regular collagen
  4. Adipose tissue and loose connective tissue Correct answer.

Explanation

The subcutaneous layer, or hypodermis, is composed largely of adipose tissue and loose connective tissue. It cushions underlying structures and helps insulate the body.

Question 45Skin Sciences: Anatomy, Physiology, and Histology

Sebum is produced by which structure?

  1. Sebaceous gland Correct answer.
  2. Eccrine gland
  3. Apocrine gland
  4. Arrector pili muscle

Explanation

Sebaceous glands secrete sebum, an oily substance that lubricates the skin and hair. These glands are usually associated with hair follicles.

Question 46Skin Sciences: Anatomy, Physiology, and Histology

Which layer of the skin is the outermost and avascular?

  1. Hypodermis
  2. Dermis
  3. Epidermis Correct answer.
  4. Fascia

Explanation

The epidermis is the outermost skin layer and contains no blood vessels. It receives nutrients by diffusion from capillaries in the underlying dermis.

Question 47Skin Sciences: Anatomy, Physiology, and Histology

The main structural protein of the epidermis is:

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

Explanation

Keratin is the fibrous protein that fills epidermal cells and gives the stratum corneum its protective, water-resistant properties. Collagen and elastin are primarily dermal proteins.

Question 48Skin Sciences: Anatomy, Physiology, and Histology

The skin's acid mantle is best described as:

  1. A neutral layer of dead cells within the dermis
  2. An alkaline secretion from eccrine glands
  3. A slightly acidic film that inhibits bacteria Correct answer.
  4. A thick oily coating made only by sebaceous glands

Explanation

The acid mantle is a thin, slightly acidic film formed by sebum and sweat on the skin surface. Its low pH helps limit the growth of many bacteria and supports barrier function.

Question 49Skin Sciences: Anatomy, Physiology, and Histology

The two layers of the dermis, from superficial to deep, are the:

  1. Papillary and reticular layers Correct answer.
  2. Basal and spinous layers
  3. Reticular and papillary layers
  4. Cornified and granular layers

Explanation

The papillary layer is the thin, superficial dermal layer, and the reticular layer is the deeper, thicker layer of dense irregular connective tissue. The other listed pairs are epidermal layers or are in reverse order.

Question 50Skin Sciences: Anatomy, Physiology, and Histology

Which dermal fiber allows skin to stretch and return to its original shape?

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

Explanation

Elastin fibers provide elastic recoil, allowing skin to stretch and then return to its resting shape. Collagen mainly provides strength and resistance to tension.
