California Esthetician — All Questions

An esthetician has just finished using stainless steel tweezers on a client. What must happen before the tweezers are immersed in disinfectant?

• a.They must be wiped with a dry towel and returned to the drawer
• b.They must be rinsed in cool water only, since soap deactivates disinfectant
• c.They must be washed with soap and water, rinsed, and dried✓
• d.They must be immersed while still soiled so the disinfectant reaches the debris

Disinfectant cannot penetrate oils, makeup, or skin debris, so every implement must first be cleaned with soap and water, rinsed, and dried before full immersion for the labeled contact time. Immersing a soiled implement wastes the solution and leaves organisms alive. Dry-wiping and storing removes nothing. Soap does not deactivate a properly used disinfectant when the tool is rinsed and dried first.CCR Title 16 §979

Which statement correctly distinguishes cleaning, disinfection, and sterilization?

• a.Sterilization is required for every implement used in a skin care establishment
• b.Sterilization destroys all microbial life including spores, while disinfection kills most pathogens on non-porous surfaces✓
• c.Disinfection destroys all microbial life, including spores
• d.Cleaning and disinfection mean the same thing and both kill bacterial spores

Sterilization is the highest level and destroys all organisms including bacterial spores; disinfection kills most pathogens on hard, non-porous surfaces but not all spores; cleaning simply removes visible soil and reduces the number of organisms. Estheticians are required to clean and disinfect, not sterilize, because they do not penetrate living tissue. Cleaning and disinfecting are two distinct, sequential steps, not synonyms.

During a leg wax the applicator stick has touched the client's skin and the esthetician needs more wax. What is the correct action?

• a.Wipe the stick on the pot rim and reuse it on the same client only
• b.Discard that applicator and use a new, clean stick for the next scoop✓
• c.Dip the same stick again since the wax is hot enough to kill germs
• d.Flip the stick over and use the opposite end for the rest of the service

Once an applicator touches skin it is contaminated, and returning it to the pot inoculates the entire container for every future client. Wax temperature is far below the level needed to kill pathogens, so heat is not a safeguard. Wiping or flipping the stick still returns a used surface and used hand contact to shared product; a fresh stick per dip is the only acceptable practice.CCR Title 16 §979

An esthetician places metal implements in an EPA-registered disinfectant. How long should they remain in the solution?

• a.For the full contact time stated on the product's label✓
• b.Overnight, because longer is always better for metal
• c.Until the next client arrives, regardless of the label
• d.For thirty seconds, which is standard for all products

EPA registration is granted for a specific contact time, and the disinfectant only performs as claimed when implements stay fully immersed for that entire labeled time. A generic thirty seconds is not valid because contact times differ by product. Waiting for the next client is arbitrary and may be too short. Excessively long soaking can corrode or pit metal and is not what the label directs.CCR Title 16 §979

Which group of items must be discarded immediately after a single client because they cannot be disinfected?

• a.Metal brow scissors and steel lash tweezers
• b.Glass electrodes and plastic mask bowls
• c.Wooden spatulas, cotton pads, gauze, and paper wax strips✓
• d.Stainless steel tweezers, comedone extractors, and metal bowls

Porous items absorb fluids into their structure, so disinfectant cannot reach and kill everything inside them; wood, cotton, gauze, and paper are single-use and must be thrown away. Stainless steel, glass, and hard plastic are non-porous and may be cleaned, disinfected, and reused. Treating a porous item as reusable is one of the most common and most serious violations found on inspection.CCR Title 16 §979

A client's skin bleeds slightly during an extraction. What is the correct exposure procedure?

• a.Blot the area with a bare fingertip and continue the extraction
• b.Rinse the area with tap water and wipe the table with a damp towel
• c.Put on gloves, stop the service, apply pressure with clean cotton, discard contaminated single-use items in a sealed bag, and clean and disinfect the area and any implement with a hospital-grade disinfectant labeled effective against HIV and HBV✓
• d.Cover the spot with makeup and finish the facial

Any blood exposure requires gloves, standard precautions, containment of contaminated single-use items, and disinfection of surfaces and non-porous implements with a product carrying an HIV/HBV kill claim. Touching blood without gloves risks transmission in both directions. Water and a damp towel do not disinfect, and covering the site with makeup contaminates the makeup and delays wound care.Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

What is the primary purpose of a Safety Data Sheet (SDS) in a skin care establishment?

• a.It replaces the need for product labels
• b.It certifies that a product is approved by the state board
• c.It lists the retail price and marketing claims of each product
• d.It provides hazard, handling, storage, first aid, and disposal information for chemical products used on site✓

An SDS is a manufacturer document describing a chemical's hazards, safe handling and storage, exposure controls, first aid, and disposal, and it must be kept accessible to every employee who works with the product. It is not a marketing sheet, not a state approval, and does not replace container labeling, which must still be intact and legible.Cal/OSHA Hazard Communication Standard (8 CCR §5194)

An esthetician follows 'standard' or 'universal' precautions. What does this mean in practice?

• a.Only clients who disclose an infection are treated as infectious
• b.Every client's blood and body fluids are treated as potentially infectious✓
• c.Gloves are worn only when the esthetician can see blood
• d.Precautions apply only to services that involve extractions

Standard precautions assume that any client may carry a bloodborne pathogen, because many carriers are asymptomatic and clients may not know or disclose their status. Relying on disclosure or on visible blood leaves the practitioner unprotected during the exposures that matter most. The principle applies to all services, not only extractions.Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

How should a container of liquid disinfectant used for implements be maintained during the workday?

• a.Kept covered, replaced according to the manufacturer's directions, and changed immediately if it becomes cloudy or contaminated✓
• b.Left uncovered so it can be reached quickly between clients
• c.Topped off with fresh concentrate whenever the level drops
• d.Reused for a full month as long as it still smells strong

A disinfectant solution loses efficacy as it is diluted by rinse water and loaded with organic debris, so it must be kept covered, changed on the manufacturer's schedule, and discarded at once if it turns cloudy or visibly soiled. Topping off does not restore concentration. Odor is not a measure of strength, and an uncovered container evaporates and collects airborne debris.CCR Title 16 §979

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

• a.Perform the facial and apply extra disinfectant to the tools afterward
• b.Perform the facial while wearing two pairs of gloves
• c.Perform the facial but avoid the lip area
• d.Decline the service, explain that the condition is contagious, and reschedule after it has healed✓

An active herpes simplex lesion is contagious and can be spread by hands, linens, and product containers, and manipulation or heat can also worsen the outbreak; the correct response is to decline politely and reschedule. Avoiding the lip area does not stop cross-contamination from droplets and hands. Disinfecting afterward and doubling gloves do not protect the client's own face or the establishment's shared product.CCR Title 16

What must be true of a disinfectant used on implements in a California skin care establishment?

• a.It must be 100 percent isopropyl alcohol
• b.It must be a fragrance-free hand soap
• c.It must be EPA-registered, hospital-grade, and labeled bactericidal, fungicidal, and virucidal, and used per label directions✓
• d.It must be a household bleach product of any concentration

The Board requires an EPA-registered, hospital-grade product with bactericidal, fungicidal, and virucidal claims, mixed and used exactly as the label directs. Hand soap is a cleaner, not a disinfectant. Undiluted or arbitrary bleach concentrations are not label-compliant, and pure alcohol evaporates too fast to hold a contact time and is not an accepted implement disinfectant.CCR Title 16 §979

An esthetician notices strong chemical fumes while mixing an exfoliating solution in a small treatment room. What is the best response?

• a.Hold her breath and finish mixing quickly
• b.Improve ventilation, keep containers closed when not in use, and use the personal protective equipment listed on the SDS✓
• c.Add water to the container to weaken the smell
• d.Open the product further to let it air out on the counter

Chemical vapors are controlled by ventilation, closed containers, and the PPE specified on the Safety Data Sheet. Leaving a product open increases vapor release, breath-holding does nothing about repeated daily exposure, and diluting a professional product off-label changes its performance and may create an unsafe or ineffective mixture.Cal/OSHA Hazard Communication Standard (8 CCR §5194)

A disinfected brow tweezer slips out of the esthetician's hand and lands on the treatment room floor. What must be done?

• a.Spray it with alcohol and use it immediately
• b.Clean it with soap and water and disinfect it again before use✓
• c.Wipe it with a tissue and continue, since the floor was mopped that morning
• d.Return it to the covered clean-implement container

A dropped implement is contaminated and must go back through the full process: clean with soap and water, rinse, dry, then immerse for the labeled contact time. A recently mopped floor is still not a clean surface. A quick alcohol spray does not provide a validated contact time, and placing a contaminated tool into the clean container contaminates every implement stored with it.CCR Title 16 §979

How must a stainless steel comedone extractor be handled between clients?

• a.Discarded after each client because it contacts skin
• b.Wiped with a cotton pad soaked in toner
• c.Rinsed under hot water and placed back on the tray
• d.Cleaned with soap and water, disinfected for the full label contact time, then stored in a clean, closed container✓

A comedone extractor is a non-porous, reusable implement, so it is cleaned, fully immersed in an EPA-registered disinfectant for the labeled contact time, dried, and stored in a covered clean container. Hot water and toner are not disinfectants. Discarding it is unnecessary because stainless steel can be effectively disinfected.CCR Title 16 §979

What is the correct handling of towels, sheets, and headbands in a skin care establishment?

• a.Folded and reused for the next client if they appear unsoiled
• b.Stored in the same bin as soiled linens to save space
• c.Shaken out and hung to dry between clients
• d.Used once per client, then placed in a closed container for soiled linens and laundered before reuse, with clean linens stored separately in a clean, closed cabinet✓

Linens are single-use per client and must be laundered before reuse, with soiled and clean linens stored in separate closed containers to prevent cross-contamination. Appearance is not a measure of contamination, since skin cells, oils, and microorganisms are invisible. Shaking soiled linens aerosolizes debris, and shared storage defeats the purpose of laundering.CCR Title 16

When must an esthetician wash her hands during a service day?

• a.Only when gloves are not worn
• b.Before and after every client, after touching the face or any contaminated surface, and after removing gloves✓
• c.Only after handling money
• d.Only at the start and end of the workday

Handwashing with soap and warm water is required before and after each client, after contact with contaminated items or surfaces, and after glove removal, since gloves can have unseen defects and hands become contaminated during removal. Limiting washing to the start and end of the day or to money handling leaves the majority of transmission opportunities unaddressed.CCR Title 16

Which statement about pathogens is accurate for a skin care practitioner?

• a.Antibiotics kill viruses as effectively as bacteria
• b.All bacteria are harmful and cause disease
• c.Fungi cannot be transmitted in a salon setting
• d.Viruses such as hepatitis B can survive on contaminated surfaces and are not treated by antibiotics✓

Hepatitis B is a durable virus that can remain infectious on surfaces, which is why an HBV kill claim matters on a disinfectant label, and antibiotics act on bacteria, not viruses. Most bacteria are non-pathogenic and some are beneficial; only pathogenic strains cause disease. Fungal infections such as tinea are readily transmitted through contaminated implements and linens.

A facial steamer has been used all week with tap water and now shows mineral scale. What is the correct maintenance approach?

• a.Empty and clean the unit per manufacturer directions, descale it, and refill with distilled water✓
• b.Continue using it, since scale does not affect the client
• c.Add a splash of implement disinfectant to the water reservoir
• d.Boil the reservoir water for ten minutes before each use

Steamers are maintained per the manufacturer's instructions, cleaned and descaled on schedule, and filled with distilled water to prevent mineral buildup that can cause spitting of hot water onto a client. Ignoring scale creates a burn hazard. Implement disinfectant is never added to a reservoir that produces breathable vapor, and boiling does not remove minerals.CCR Title 16

An esthetician uses the same unwashed makeup brush on two clients. This is an example of what type of transmission?

• a.Transmission that cannot occur because makeup contains preservatives
• b.Indirect transmission through a contaminated object✓
• c.Direct transmission through skin-to-skin contact
• d.Airborne transmission through respiratory droplets

Indirect transmission occurs when a pathogen moves from one person to another by way of a contaminated object such as a brush, implement, or linen. Direct transmission requires person-to-person contact, and airborne transmission travels through droplets or particles in the air. Cosmetic preservatives limit product spoilage but do not disinfect a brush between clients.

How should used cotton pads, gauze, and wax strips be disposed of at the end of a service?

• a.In a covered, lined waste container that is emptied regularly, with any blood-contaminated items bagged separately✓
• b.In an open basket beside the treatment bed
• c.Rinsed and set aside for reuse on the same client
• d.In the same container used for clean supplies

Single-use contaminated items go into a closed, lined waste receptacle so debris is not exposed to air, hands, or the next client, and items contaminated with blood are bagged and handled as regulated waste. Open baskets, shared clean-supply storage, and reuse all create direct cross-contamination pathways.CCR Title 16

A loyal client says she is comfortable with the esthetician re-dipping her wax stick because 'it's only my own germs.' How should the esthetician respond?

• a.Explain that the wax pot is shared with all clients, so no re-dipping is permitted regardless of client preference✓
• b.Agree, because a client may waive sanitation rules for her own service
• c.Re-dip only once and note it on the client's chart
• d.Re-dip but discard the top layer of wax afterward

A client cannot consent away a health and safety rule, because the contamination risk falls on every other client who uses that shared pot. Documenting the violation or skimming the surface does not remove organisms that have already dispersed into the wax. The correct answer is a clear explanation and a fresh applicator for every dip.CCR Title 16 §979

An esthetician has a small open cut on her finger on the morning of a full facial schedule. What is the appropriate action?

• a.Cover the cut with a bandage and a finger cot or glove, and keep it covered for every service✓
• b.Cancel all services for two weeks
• c.Apply implement disinfectant to the cut before each client
• d.Perform services as normal because the cut is small

An open lesion is a two-way route for bloodborne pathogens, so it must be covered with a bandage and a barrier such as a glove or finger cot for every service. Working with the cut uncovered exposes both parties. Canceling two weeks of work is unnecessary, and implement disinfectants are not designed for use on skin wounds.Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

Which best describes acquired immunity?

• a.Resistance developed after exposure to a pathogen or after vaccination✓
• b.The body's physical barriers, such as unbroken skin
• c.Protection a person is born with that resists all infection
• d.The ability of a disinfectant to kill spores

Acquired immunity develops after the immune system encounters a pathogen naturally or through immunization, such as the hepatitis B vaccine. Natural immunity is what a person is born with, and unbroken skin is a component of that natural, non-specific defense. Spore-killing describes sterilization, not immunity.

After disinfection, how must clean implements be stored?

• a.In the disinfectant container permanently
• b.Dry, in a clean, covered container or drawer used only for disinfected implements and labeled as clean✓
• c.On an open tray beside the treatment bed
• d.Loose in a drawer with product samples

Disinfected implements must be dried and kept in a clean, covered, clearly designated container so they are not recontaminated by dust, spray, or hands. Storing them loose with other items or on an open tray exposes them again. Leaving them permanently in solution corrodes metal and does not meet the requirement for dry, covered storage.CCR Title 16 §979

Which practice is prohibited in a licensed California skin care establishment?

• a.Keeping a pet in the service area or preparing and eating food where services are performed✓
• b.Storing clean linens in a closed cabinet
• c.Keeping a covered waste container in the treatment room
• d.Posting the establishment license where clients can see it

Animals other than service animals, and food preparation or consumption in the area where services are performed, are prohibited because both introduce contamination. Covered waste containers, closed clean-linen storage, and a posted license are all required or expected practices rather than violations.CCR Title 16

An esthetician opens a new concentrate and estimates the dilution 'by eye' because the measuring cup is missing. What is wrong with this?

• a.A disinfectant only performs as EPA-registered when mixed at the exact label dilution, so it must be measured accurately✓
• b.Nothing, because a stronger mixture is always safer
• c.Nothing, as long as the solution looks the same color as usual
• d.It is acceptable if the implements are left in longer to compensate

EPA registration and the stated kill claims apply only at the labeled dilution; too weak fails to kill pathogens and too strong wastes product, damages implements, and increases skin and respiratory irritation. Color is not a measure of concentration, and extending soak time does not correct an incorrect concentration.CCR Title 16 §979

Why is 70 percent isopropyl alcohol generally more effective as an antiseptic than 99 percent alcohol?

• a.Because higher concentrations are illegal in salons
• b.Because the water content helps alcohol penetrate the cell wall, and the slower evaporation extends contact time✓
• c.Because it is less expensive to produce
• d.Because it evaporates faster and therefore contacts more organisms

Water in a 70 percent solution allows the alcohol to enter microbial cells rather than instantly coagulating the outer proteins, and the slower evaporation keeps the surface wet longer. Faster evaporation is a drawback, not a benefit. Cost is irrelevant to efficacy, and high-percentage alcohol is not itself illegal, just less effective as an antiseptic.

A salon owner points to a UV cabinet and says implements do not need liquid disinfection because the cabinet 'sterilizes' them. Is this correct?

• a.No, because UV cabinets are prohibited in California
• b.No, a UV cabinet may be used only as a clean, covered storage container after proper cleaning and disinfection✓
• c.Yes, ultraviolet light sterilizes any implement placed inside
• d.Yes, as long as the implements stay inside for one minute

Ultraviolet cabinets do not reliably reach every surface of an implement and are not accepted as a disinfection method; they may serve only as covered storage for items already cleaned and disinfected in an EPA-registered solution. Short exposure times do not change that. The cabinets themselves are not banned, they are simply not a substitute for disinfection.CCR Title 16 §979

A new client presents with an itchy, spreading rash of unknown origin across the cheeks and jawline. What should the esthetician do?

• a.Diagnose it as contact dermatitis and recommend a cortisone cream
• b.Decline the service, refer the client to a physician for diagnosis, and rebook after medical clearance✓
• c.Perform a gentle facial and apply a soothing mask
• d.Perform an exfoliating treatment to clear the rash faster

Estheticians are not permitted to diagnose or treat a skin disease, and an undiagnosed spreading rash may be contagious or a medical condition that services would worsen. The safe response is to decline, refer to a physician, and rebook after clearance. Naming a condition or recommending a medication is diagnosis and prescription, and exfoliating inflamed skin causes further damage.CCR Title 16

Which of the following signs would most clearly indicate that a client should not receive a service that day?

• a.Uneven skin tone from past sun exposure
• b.A warm, red, swollen area with pus draining from the skin✓
• c.Mild dryness with flaking on the cheeks
• d.Non-inflamed closed comedones on the forehead

Heat, redness, swelling, and drainage are classic signs of an active infection, which is a medical condition and an absolute contraindication for a service; the client must be referred to a physician. Dryness, closed comedones, and sun-related pigment changes are common cosmetic conditions that estheticians routinely address within their scope.CCR Title 16
