CSLB General Building (B) — All Questions

California nail salons must bring their reusable implements to which level of decontamination?

• a.Sanitizing with soap and water only
• b.Sterilization in an autoclave
• c.Disinfection with an EPA-registered product after cleaning✓
• d.Wiping with 70 percent rubbing alcohol

Disinfection kills most pathogens on hard, non-porous surfaces and is the level California requires in nail salons. Soap and water only removes soil and is the first step, never a substitute. Sterilization destroys all microbial life including spores but is not required or practical for salon work, and rubbing alcohol is not a hospital-grade disinfectant.

A sales rep visits your salon with four products for soaking metal implements. Which one meets California requirements?

• a.A hospital-grade disinfectant registered with the EPA and labeled bactericidal, fungicidal and virucidal✓
• b.A scented household spray that advertises it cuts grease and grime
• c.A jar of 70 percent isopropyl alcohol
• d.Quaternary ammonium wipes sold for cleaning countertops

California requires an EPA-registered, hospital-grade disinfectant whose label carries bactericidal, fungicidal and virucidal claims. Household cleaners only clean and make no kill claim against pathogens. Alcohol and countertop quat wipes are not accepted substitutes for a hospital-grade implement disinfectant.U.S. EPA registration of disinfectants (FIFRA)

Your disinfectant label states a 10-minute contact time. You clean your metal nippers and then rest them in the tray with only the tips touching the solution for about three minutes. What is wrong?

• a.Nothing, because the nippers were cleaned first
• b.Three minutes is fine as long as you wipe them dry afterward
• c.Metal nippers should never be placed in a liquid disinfectant
• d.The implement must be completely immersed for the full contact time stated on the label✓

The label contact time is the minimum soaking time, and the whole implement must be under the solution. Any part above the liquid is never disinfected, and cutting the time short leaves live pathogens on the blades. Cleaning first is required but does not shorten the soak, and metal nippers are exactly the kind of non-porous tool meant to be immersed.CCR Title 16 §979

Which statement about sterilization is accurate for a nail salon?

• a.A salon disinfectant sterilizes implements if you leave them soaking overnight
• b.Sterilization destroys all microbial life including bacterial spores and requires equipment such as an autoclave✓
• c.Sterilizing and sanitizing mean the same thing
• d.Boiling implements in water for five minutes sterilizes them

Sterilization destroys every form of microbial life, spores included, and requires an autoclave; it is not required for California nail services. Leaving tools in disinfectant longer does not turn disinfection into sterilization. Sanitizing is only the soap-and-water removal of soil, and boiling does not reliably destroy spores.

You just finished a manicure and your metal cuticle pusher has visible debris and oil on it. What must happen before it goes into the disinfectant?

• a.Wash it with soap and water, scrub off the debris, and rinse it✓
• b.Wipe it on a dry towel and drop it straight in
• c.Leave it in the solution twice as long to make up for the debris
• d.Spray it with alcohol and let it air dry

Cleaning with soap and water and rinsing is the required first step, because debris and oil shield germs so the disinfectant cannot reach them. Wiping on a towel or spraying alcohol does not remove that film. Doubling the soak time does not fix a dirty implement, and the soil also breaks down the solution for every tool in the jar.CCR Title 16 §979

A pedicure is finished. Which group of items must all be thrown away because they cannot be disinfected?

• a.Metal toenail clippers, metal pusher and stainless steel tweezers
• b.Glass bowl, metal file handle and metal drill bit
• c.Emery board, wooden pusher, foam toe separators and pumice stone✓
• d.Manicure table, armrest and the lamp handle

Those items are porous, so disinfectant cannot penetrate them and they are single-use, going in the trash after one client. Metal and glass items are non-porous and are cleaned and disinfected for reuse. The table, armrest and lamp are surfaces that get cleaned and disinfected, not discarded.

Midway through a busy Saturday you notice the disinfectant in your jar has turned cloudy with bits of nail dust floating in it. What is required?

• a.Add fresh concentrate to the jar to strengthen what is already there
• b.Empty the jar, clean it, and mix a fresh batch according to the label✓
• c.Strain the debris out and keep using the same solution
• d.Keep using it until closing time and change it at the end of the day

Cloudy or visibly dirty solution is no longer effective and must be discarded and replaced with a freshly mixed batch, and the container itself has to be cleaned. Topping off or straining does not restore the kill power, because organic soil neutralizes the active ingredient. Waiting until closing means every client until then receives tools that were never truly disinfected.CCR Title 16 §979

Which of these items may be cleaned, disinfected and used on the next client?

• a.The buffer block used to shine the nails
• b.The orangewood stick used to push back dead tissue
• c.The foam slippers the client wore
• d.The stainless steel nipper used on a hangnail✓

A stainless steel nipper is non-porous, so it can be washed, rinsed, fully immersed in disinfectant for the label contact time and reused. Buffer blocks, wooden sticks and foam slippers are porous and soak up moisture and debris, so disinfectant cannot reach the germs inside them and they are discarded after one client.

To be used on nail implements in California, a disinfectant label must show that the product kills which three groups of organisms?

• a.Bacteria, fungi and viruses✓
• b.Bacteria, spores and insects
• c.Viruses, spores and mold only
• d.Fungi and dust mites only

The label must carry bactericidal, fungicidal and virucidal claims, meaning the product kills bacteria, fungi and viruses, which are the pathogens that actually pass between clients in a salon. Killing bacterial spores is sterilization, which salon disinfectants do not claim. Insects and dust mites have nothing to do with disinfectant efficacy claims.U.S. EPA registration of disinfectants (FIFRA)

You lift your disinfected metal implements out of the solution with tongs and dry them. Where do they belong now?

• a.Back in the disinfectant jar so they stay wet until the next client
• b.In a clean, closed, labeled dry container reserved for disinfected implements✓
• c.Loose in the top drawer alongside the used tools from this morning
• d.In an open tray on the manicure table

Disinfected implements are dried and stored in a clean, covered container that is labeled as clean or disinfected and kept separate from used tools. Leaving them sitting in the solution can corrode them and the solution weakens over time. An open tray or a drawer shared with dirty tools recontaminates them before the next client even sits down.CCR Title 16 §979

Why must disinfectant concentrate be measured and mixed exactly as the manufacturer's label directs?

• a.A stronger mix always disinfects faster, so more concentrate is preferred
• b.The dilution only affects how strongly the product smells
• c.Too weak will not kill the pathogens, and too strong can damage implements and irritate skin and lungs✓
• d.The label ratio is only a suggestion as long as tools soak overnight

The EPA registration is based on the exact dilution and contact time on the label, so any other mix is unproven and using it is a violation. An under-diluted solution leaves pathogens alive, while an over-concentrated one can pit and corrode implements and irritate skin and airways. Soaking longer does not rescue a solution that was mixed wrong.

Your electric file handpiece and the handle of your table lamp cannot be put in liquid. How are they disinfected between clients?

• a.Clean off the dust, then wipe or spray them with an EPA-registered disinfectant and keep the surface visibly wet for the label's contact time✓
• b.Blow the dust off with compressed air and move on
• c.Immerse them in the same jar used for the metal implements
• d.They need no disinfection because they never touch the client's skin

Non-immersible electrical items are first cleaned of dust and residue, then wiped or sprayed with an EPA-registered disinfectant that must stay visibly wet on the surface for the full contact time. Immersing an electrical item destroys it and creates a shock hazard. Compressed air just scatters contaminated dust, and both items are handled constantly, so they do require disinfection.CCR Title 16 §980

A regular client asks you to keep her favorite emery board in a drawer with her name on it for her next visit. What should you do?

• a.Write her name on it and store it in the client drawer
• b.Soak it in disinfectant for ten minutes and then store it
• c.Brush the dust off and seal it in a plastic bag with her name
• d.Explain that a used porous file cannot be disinfected, and either give it to her to take home or discard it✓

A file is porous, so disinfectant cannot reach the germs trapped in the abrasive surface, and it is single-use in the salon. Naming, bagging or soaking it keeps a contaminated item in service and would be cited by an inspector. The acceptable outcomes are to hand the used file to the client to take home or to throw it away.

One client has just left and the next one is sitting down. What is the single most effective thing you can do to stop the spread of infection?

• a.Pull on a fresh pair of gloves without washing first
• b.Wash your own hands with soap and warm water before touching the next client✓
• c.Have the client rub hand sanitizer on her hands
• d.Change the towel on the armrest

Hand washing with soap and warm water is the single most effective infection-control measure, and it is done before and after every client, after handling used implements and after any break. Gloves pulled over unwashed hands still spread germs to the table, the tools and the product jars. Client sanitizer and a fresh towel help, but neither replaces washing your own hands.

Which statement about viruses in a salon setting is correct?

• a.HIV survives for weeks on a countertop and is the main salon concern
• b.Viruses cannot be carried on implements, only through the air
• c.Hepatitis B survives on surfaces longer than HIV, which makes it the greater salon risk✓
• d.Hepatitis B is destroyed by soap and water alone

Hepatitis B is hardy outside the body and survives on contaminated surfaces and implements far longer than HIV, so it is the greater practical risk in a nail salon. HIV is fragile once it leaves the body. Implements and surfaces certainly can carry viruses, and soap and water only cleans; an EPA-registered disinfectant labeled virucidal is what inactivates the virus.

You file acrylic all day and the trash at your station is an open basket of acetone-soaked cotton. What should you change?

• a.Use a covered waste can with a self-closing metal lid, empty it daily, and wear an N95-type dust mask while filing✓
• b.Aim a ceiling fan at your station to move the vapors around the room
• c.Rely on the dust mask alone to protect you from the acetone vapors
• d.Prop the front door open and leave the basket where it is

Chemical-soaked cotton belongs in a covered waste container with a self-closing metal lid that is emptied every day, and an N95-type mask should be worn for filing dust. A ceiling fan only stirs vapors around instead of capturing them at the table, which is what source-capture ventilation does. A dust mask filters particles, not vapors, so it cannot be your protection against acetone fumes.

Your last client has left and there is filing dust and a smear of lotion on the manicure table and the armrest. What is the correct procedure before the next client?

• a.Cover the table with a clean towel and begin the next service
• b.Spray disinfectant over the dust and wipe it off right away
• c.Vacuum the dust and wipe the table with a damp paper towel
• d.Clean the surfaces with soap and water first, then apply disinfectant and let it stay wet for the label's contact time✓

A work surface must be cleaned of dust, lotion and product residue before the disinfectant goes on, and the disinfectant then has to remain visibly wet for the labeled contact time. Wiping it off immediately ends the contact time before it can kill anything. Covering soil with a towel or only damp-wiping leaves the contamination sitting under the next client's hands.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

What is required of a California nail salon regarding Safety Data Sheets?

• a.They are needed only for products labeled flammable
• b.An SDS must be kept on the premises for every chemical product and be available to employees and inspectors✓
• c.They stay at the manufacturer's office and are requested only after an accident
• d.Only the salon owner is permitted to read them

An SDS must be kept at the salon for every chemical product used or stored there, and employees as well as Board and Cal/OSHA inspectors must be able to look at them. Each sheet lists the hazards, ingredients, first aid, safe handling, storage and required protective equipment. They are not limited to flammable products, they are not kept offsite, and every employee has the right to read them.Cal/OSHA Hazard Communication Standard (8 CCR §5194)

You have just finished a pedicure and your next client is already waiting. Before that client puts her feet in the same foot spa, what must you do?

• a.Drain the water, spray the inside of the basin with alcohol, and wipe it dry with a clean towel.
• b.Drain the water, refill with hot soapy water, and let it circulate while you walk the first client to the front desk.
• c.Drain the basin, remove and clean the screen or filter and the area behind it, scrub the basin with soap, rinse, then refill with water and an EPA-registered disinfectant and circulate it for the full contact time on the label before draining and air drying.✓
• d.Drain the basin, wipe it with a disinfectant wipe, and save the full cleaning for closing time.

The complete procedure in option C is required after every single client, because only circulating an EPA-registered disinfectant for the label contact time kills the bacteria and fungus left behind. Alcohol is not a hospital-grade salon disinfectant and never reaches the debris behind the screen, so A fails. Soapy water only cleans, it does not disinfect (B), and end-of-day cleaning does not replace the between-client procedure (D).California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

An inspector watches a technician empty a pedicure tub, wipe it out with a paper towel, and refill it for the next client. Why is this a violation?

• a.The tub should have been refilled with distilled water instead of tap water.
• b.The technician used a paper towel instead of a clean cloth towel.
• c.The tub must be dried with a fan before it can be refilled.
• d.Wiping only removes what you can see; the basin was never scrubbed with soap and no EPA-registered disinfectant was ever circulated for the label contact time, so organisms in the screen, the jets and the plumbing are still alive.✓

Draining and wiping is a cleaning step, not disinfection, so answer D describes the real problem: the pathogens most likely to infect the next client hide in the filter area and the water lines, which a towel never touches. The type of water (A) and the type of towel (B) are not what the rule addresses. Air drying is required after the disinfectant is drained, but a fan (C) is not a substitute for the disinfection step itself.

It is closing time and you are in charge of the two pedicure chairs. What does the end-of-day foot spa procedure require?

• a.Remove the screen or filter, clean out all the trapped debris, scrub the screen and the surface behind it with soap and water, put it back, then refill with water and disinfectant, circulate for the full contact time, drain and air dry.✓
• b.Fill the tub with very hot water and circulate it for an hour to flush the pipes.
• c.Wipe the outside of the chair and the footrest with a disinfectant wipe and leave the basin empty and dry.
• d.Pour undiluted bleach into the empty basin and leave it there until morning.

The end-of-day routine in option A is built around opening up the screen or filter, because that is where hair, skin and product collect and feed bacteria overnight. Hot water alone (B) has no disinfecting power. Wiping the outside of the chair (C) ignores the basin entirely, and undiluted bleach sitting in an empty basin (D) is not a labeled use, damages the equipment and does not replace the required circulated disinfection.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

Every Sunday night your salon performs the extra foot spa cleaning that is required at least once a week. After the normal daily cleaning is finished, what happens next?

• a.The tub is filled with water and disinfectant, circulated for thirty minutes, and drained right away.
• b.The tub is filled with plain hot water and left overnight, then drained in the morning.
• c.The tub is filled with water and disinfectant (or a low-foaming bleach solution where the label allows it), and that solution is left sitting in the tub overnight for at least six hours without circulating, then drained, flushed with clean water and air dried.✓
• d.The jets and the screen are pulled out and soaked in acetone overnight.

The weekly step is defined by the long soak: the solution has to sit undisturbed in the tub for at least six hours, which is what makes option C correct, and then the tub is drained, flushed and air dried. A thirty-minute circulation (A) is only the daily level of cleaning. Plain hot water (B) has no disinfecting action, and acetone (D) is a solvent for product, not a disinfectant, and would damage the equipment.

A Board inspector walks in without notice and asks to see the records for your pedicure spas. What must you be able to produce?

• a.Receipts showing you bought disinfectant within the last thirty days.
• b.A dated cleaning record for each foot spa showing what cleaning was done and who did it.✓
• c.A signed note from each client saying the tub looked clean.
• d.The manufacturer's warranty card and installation paperwork for each pedicure chair.

Each foot spa must have its own dated cleaning log that is kept in the salon and shown to the inspector on request, which is what option B describes. Purchase receipts (A) prove you own disinfectant but not that any tub was ever cleaned. Clients are not responsible for verifying disinfection (C), and warranty paperwork (D) has nothing to do with health and safety compliance.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

How does the required cleaning and disinfection routine for a pipeless pedicure tub compare with the routine for a whirlpool tub that has jets and plumbing?

• a.It is the same requirement for both: cleaned and disinfected after every client, at the end of every day, and at least once a week, because both hold water against a client's skin and both trap debris.✓
• b.A pipeless tub only needs to be wiped out, because there is no plumbing where bacteria can hide.
• c.A whirlpool tub needs only the weekly service; a pipeless tub needs the after-client service.
• d.A pipeless tub needs disinfecting only when a client has broken skin.

Both styles of tub follow the identical schedule, so option A is correct: a pipeless unit still has an impeller, a screen and a basin surface where skin, hair and product collect. Believing the pipeless design is self-cleaning (B) is one of the most common salon mistakes and a frequent citation. Options C and D invent a lighter standard that does not exist for either tub.

A client sits down for a pedicure and you see a fresh razor cut on her lower leg from shaving that morning; the skin is still open. What should you do?

• a.Go ahead with the pedicure but keep the water level below the cut.
• b.Cover the cut with a bandage and perform the whole service, including the soak.
• c.Dab antiseptic on the cut and start the soak.
• d.Keep her foot and leg out of the foot spa, explain that an open break in the skin is an easy way for bacteria to get in, and offer a waterless pedicure or reschedule once the skin has healed.✓

Broken skin removes the body's main barrier, and warm circulating spa water is exactly where an organism can enter, so option D is the safe and professional choice. Lowering the water (A) does not control splashing or the wet leg rest. A bandage (B) does not stay sealed in water, and antiseptic (C) does not close the wound or make the tub safe for a fresh cut.

While you are trimming a hangnail, the nipper nicks the client's skin and it starts to bleed. What is the correct thing to do?

• a.Press the shop's styptic pencil directly on the cut and keep working.
• b.Stop the service immediately, put on gloves, clean the injury, apply an antiseptic, and cover it with a bandage or a finger guard before deciding whether to continue.✓
• c.Finish the nail first so the polish is not ruined, then clean the cut.
• d.Rinse the finger at the sink and keep going bare-handed because it is only a drop of blood.

Option B is the required sequence: stop, glove up, clean, antiseptic, cover, and only then decide about continuing. A shared styptic pencil or alum block touches one client's blood and then the next client's, which is prohibited; use a powder or liquid styptic applied with a disposable applicator, so A is wrong. Continuing to work (C) or handling blood bare-handed (D) exposes both of you to bloodborne pathogens such as hepatitis B.Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

After you bandage the client's finger, your table has a cotton ball, a gauze square and a paper towel with blood on them. How do you dispose of them?

• a.Drop them into the open wastebasket under the table with the rest of the day's trash.
• b.Rinse the blood off in the sink and then throw them away.
• c.Double-bag them and place them in a sealed bag or a closed, covered container kept for contaminated waste.✓
• d.Soak them in disinfectant for ten minutes and reuse them on the same client.

Single-use items with blood on them are contaminated waste: double-bag them and put them in a sealed bag or closed container, which is option C. An open trash can (A) lets contaminated cotton be touched by the next person who empties it. Rinsing blood into the salon sink (B) spreads it to a surface used for washing hands, and porous items like cotton and gauze can never be disinfected and reused (D).Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

The metal nipper that caused the nick has blood on the blade. What do you do with that implement?

• a.Clean it with soap and water, then fully immerse it in an EPA-registered disinfectant labeled effective against HIV and hepatitis B — or in a 10% bleach solution — for the contact time on the label.✓
• b.Wipe the blade with a 70% alcohol pad and put it back in your tool drawer.
• c.Put it straight into the disinfectant jar without washing it, since the disinfectant will dissolve the blood.
• d.Throw it away, because any implement that touches blood can never be used again.

Option A is the required two-step handling: clean first so blood and debris cannot shield organisms, then fully immerse in a disinfectant with an HIV and hepatitis B claim (or 10% bleach) for the full label contact time. An alcohol wipe (B) does not meet that standard for a blood-contaminated tool. Skipping the cleaning step (C) leaves protein on the blade that blocks the disinfectant, and a metal nipper is non-porous and does not have to be discarded (D).Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

Why is MMA (methyl methacrylate) monomer prohibited in nail products in California?

• a.It cures too slowly, and clients will not sit still long enough for it to harden.
• b.It costs much more than the approved monomers.
• c.It does not hold color well and turns yellow in sunlight.
• d.It bonds far too aggressively and cures far too hard, so the enhancement will not soak off — the natural nail plate tears, thins or lifts off with it — and it can cause allergic contact dermatitis and lasting nail damage.✓

Option D states the real reason: MMA is not a nail-product monomer, it grips harder than the nail plate itself, so the nail gives way before the product does, and repeated exposure sensitizes the skin. EMA (ethyl methacrylate) is the accepted monomer for salon use. MMA is actually cheap and cures quickly, which is exactly why some shops use it, so A and B are backwards, and yellowing (C) is a cosmetic issue, not the reason for the ban.

A new client says that at her last salon the acrylic would not dissolve in acetone, the technician had to grind it off with a very coarse drill bit, the set felt unusually hard and heavy, and the shop had a strong strange odor. What do these signs point to?

• a.The salon used UV gel instead of liquid and powder.
• b.The salon used too much acid primer under the product.
• c.The salon was very likely using MMA, which is prohibited in California nail products.✓
• d.The salon used a polymer powder that was past its expiration date.

Those four clues together — will not soak off in acetone, needs an aggressive drill, unusually hard and heavy, strong odd odor — are the classic warning signs of MMA, so option C is correct. UV gel (A) also has to be filed off, but it does not create that odor or that weight and it is legal. Too much acid primer (B) burns the nail plate but does not change how the product dissolves, and expired powder (D) causes slow curing and discoloration, not indestructible product.

The owner of the salon where you just started hands you an unlabeled jug of monomer with a very strong odor and tells you to use it because it lasts longer and costs less. What should you do?

• a.Use it during your shift but keep your own EMA monomer for your regular clients.
• b.Refuse to use it, tell the owner the product is prohibited in California, and report the salon to the Board of Barbering and Cosmetology.✓
• c.Use it only on clients who ask for the strongest possible set, and warn them about the smell.
• d.Use it but wear a dust mask and prop the back door open for ventilation.

Option B is the only correct answer: a prohibited product stays prohibited no matter who tells you to use it, and it is your license that is on the line along with your clients' nails. Using it part of the time (A and C) is still using it, and a client cannot consent to a banned product. A dust mask (D) filters dust, not vapors, and no amount of fresh air makes an illegal monomer legal.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

A regular client points at the thick callus on her heel and asks you to just shave it off with a credo blade the way her last salon did. What is the correct response?

• a.Explain that credo blades and razor-type callus shavers are prohibited in California and that cutting living skin is outside a manicurist's scope, then reduce the callus with a foot file or rasp instead.✓
• b.Use the credo blade only on the thickest part, where she cannot feel anything.
• c.Use the credo blade and then disinfect it thoroughly afterward.
• d.Use the blade but put in a brand-new disposable blade so it is sanitary.

Answer A is correct because the tool itself is prohibited and because slicing living tissue is a medical act a manicurist may not perform. Thick callus still has living skin under it, so B is not safer, it just makes the injury harder for the client to notice. Disinfecting afterward (C) and using a fresh blade (D) address contamination only; they do not make a prohibited procedure legal or stop the cutting injury.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

During a pedicure you find a corn on the side of one toe, a deep cracked callus on the heel, and a toenail growing down into the flesh that is tender to the touch. What is within your scope of practice?

• a.Cut the corn out and lift the ingrown nail edge free with a curved probe.
• b.Trim the ingrown corner of the nail and file the corn down level with the skin.
• c.Smooth the callus with a foot file only, leave the corn and the ingrown nail alone, and refer the client to a podiatrist.✓
• d.Soak the foot longer so the tissue softens, then remove all three with a nipper.

Option C is the correct scope: a manicurist may reduce callus with a foot file, but a corn and an ingrown toenail involve living tissue and belong to a podiatrist. Cutting or probing an ingrown nail (A and B) is a medical procedure and a common cause of serious infection. Soaking softens tissue but changes nothing about scope, so D would still be cutting living skin.

A new client takes off her socks and the skin around one big toenail is red, swollen, warm and has a small amount of pus. What should you do?

• a.Service the other nine toes and simply skip that one.
• b.Tell her she has a nail infection and recommend an antifungal cream from the drugstore.
• c.Do the pedicure anyway and disinfect the tub twice afterward.
• d.Politely decline the service, describe only what you see without naming a condition, explain that you are not allowed to work on inflamed or infected skin, and suggest she see a physician.✓

Redness, swelling, heat and pus are signs of an active infection, so option D is the professional response: describe, decline, refer, and never diagnose. Skipping one toe (A) does not help because the spa water, the towels and your implements still contact the infected area and the rest of the foot. Naming a disease and recommending medication (B) is diagnosing, which is outside your scope, and extra tub cleaning (C) protects the next client but still exposes this client to a worse infection.

Which manicuring station is set up the way California health and safety rules require?

• a.An open wastebasket for used cotton, a coffee cup on the table, and monomer poured into a clean drinking-water bottle so it is easier to pour.
• b.A covered waste container with a self-closing lid for chemical-soaked cotton, every product in its original labeled and closed container, and no food, drink or smoking at the table.✓
• c.A covered waste container, an unlabeled squeeze bottle of acetone, and a snack kept in the drawer.
• d.An open trash can emptied every night, drinks allowed as long as they have a lid, and a scented candle burning to cover the product odor.

Option B meets all three requirements at once: solvent-soaked cotton goes in a covered self-closing container, chemicals stay in closed original containers with their labels, and food, drink and smoking stay away from the products. Putting monomer in a drinking bottle (A) and leaving acetone unlabeled (C) are exactly how accidental poisonings happen, and an unlabeled container also breaks the labeling rule. An open flame near acetone and monomer vapors (D) is a fire hazard, and a candle only masks odor instead of removing vapor.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

A new client sits down for a basic manicure. Before you pick up a single implement, what should you do first?

• a.Consult with the client and inspect the nails and surrounding skin for anything that would prevent service✓
• b.Remove the old polish from all ten nails
• c.Soak the hands in warm soapy water to soften the tissue
• d.File the free edge into the shape she requested

The consultation and a careful look at the nails and skin always come first, because what you find may mean you cannot legally perform the service at all. Removing polish, soaking and filing are later steps in the procedure. If you soak and file first and only then notice a red, swollen, infected finger, you have already exposed the client and your implements.

Your client's natural nails are thin, soft and peeling at the free edge. What filing technique should you use?

• a.Saw the file back and forth quickly so the nail is shortened in less time
• b.File from the center of the free edge outward toward each sidewall
• c.File in one direction only, working from the side toward the center of the free edge✓
• d.Lay the file flat on top of the nail plate and thin the surface first

On soft or fragile nails you file in one direction, side to center, so the layers of the plate are pressed together instead of pulled apart. Sawing back and forth creates heat and friction and tears the layers, which is exactly what causes peeling. Filing from center outward drags the layers toward the corners, and filing the top of the plate thins a nail that is already weak.

You are shortening and shaping a client's natural nails. Which abrasive is appropriate?

• a.A very coarse abrasive around 80 grit, the same one used to shape acrylic
• b.A medium-to-fine abrasive of about 180 grit or higher✓
• c.A metal file, because it lasts longer than a paper file
• d.Any grit works as long as you file gently

The lower the grit number, the coarser and more aggressive the abrasive, so a natural nail is shaped with about 180 grit or finer. An 80 grit file is made for shaping hard enhancement product and will shred a natural plate. Metal files tear the layers of the plate, and pressing lightly with a coarse file still removes far too much nail.

During a manicure the client asks you to cut all of her cuticle away because she likes how clean it looks. What should you do?

• a.Cut it carefully with sharp disinfected nippers, since the client asked for it
• b.Cut only the skin along the sidewalls and leave the base of the nail alone
• c.Soak the finger longer first, because soaking makes trimming the living skin safe
• d.Explain that you may only remove loose dead tissue from the nail plate and may not cut living skin✓

In California a manicurist may not cut living tissue, so the eponychium and the sidewalls stay intact no matter what the client requests. Only the thin, dead, colorless tissue clinging to the nail plate may be softened with cuticle remover, gently pushed back and removed. Cutting living skin opens a doorway for bacteria and can cause paronychia, and soaking does not make it legal or safe.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

What is the main purpose of a base coat in a polish service?

• a.It improves adhesion of the color and keeps dark pigment from staining the natural nail✓
• b.It seals the color and provides the final shine
• c.It makes the color coats dry faster
• d.It hardens the nail plate so the nail cannot break

A base coat is formulated to grip both the nail plate and the color coat, and it puts a barrier between pigment and keratin so reds and dark shades do not leave a yellow stain. Sealing and shine are the job of the top coat, applied last. A base coat is not a drying accelerator and it does not change the strength of the nail plate itself.

A client's gel color keeps lifting within a few days. You realize the salon is curing an LED gel line under an old lamp that came with a different brand. What is the most likely cause?

• a.The gel was applied in coats that were too thin
• b.The lamp does not match the wavelength and output the gel needs, so the product is not curing completely✓
• c.The client is washing her hands too often
• d.The finished nails were wiped with alcohol after the final cure

Gel cures only when its photoinitiators receive the specific wavelength and intensity the manufacturer specifies, so the wrong lamp leaves the product under-cured, which causes lifting and can also sensitize the client. Thin, even coats are correct technique and are not the problem. Hand washing does not lift a properly cured gel, and wiping the inhibition layer with alcohol after the final cure is a normal finishing step.

As you carry an acrylic bead to the nail it runs down the brush and floods the area near the client's skin. How should you correct your ratio?

• a.Add more monomer so the bead flows even more easily
• b.Cure the bead under a UV lamp to firm it up
• c.Pick up less liquid so the bead is drier and holds a smooth, medium-firm shape✓
• d.Work faster so the bead has no time to run

A bead that runs is too wet, meaning too much monomer for the amount of polymer, and it will flood the sidewalls and the skin at the base and cause lifting and possible sensitization. Picking up less liquid gives a bead that sits like a soft ball and can be pressed into place. Adding more monomer makes it worse, and liquid-and-powder cures by polymerization on its own and never goes under a lamp.

How much of the natural nail plate should a plastic nail tip cover?

• a.No more than one-third of the natural nail plate✓
• b.About one-half of the plate
• c.About two-thirds of the plate, for extra holding power
• d.The entire plate, so the tip cannot pop off

The contact area of a tip is limited to no more than one-third of the natural nail so the plate can still flex and grow normally. Covering half, two-thirds or the whole plate seals in moisture, blocks the nail from bending with the finger and makes lifting and damage more likely. Holding power comes from a well-fitted tip and the overlay product, not from covering more nail.

How is a nail form used?

• a.It is glued on top of the nail plate and then filed thin
• b.It replaces the base coat underneath the polish
• c.It is placed over the base of the nail to shield the skin while filing
• d.It is fitted snugly under the free edge so the technician can sculpt an extension without a tip✓

A form slides under the free edge and follows the natural curve of the finger, giving the technician a temporary platform on which to build a sculpted extension, then it is peeled away. It is not glued to the plate, since that is a tip. It has nothing to do with polish and it is not a skin shield.

A client cracks one natural nail across the stress area and does not want a full set of enhancements. What is the appropriate repair?

• a.Fill the crack with a thick layer of top coat and let it dry
• b.Apply a silk or fiberglass wrap over the crack with cyanoacrylate adhesive and an activator✓
• c.Glue the crack shut and then file the nail down below the split
• d.Cover the nail with two extra coats of colored polish

A fabric wrap bonded with cyanoacrylate adhesive is designed exactly for this: it is light, thin and natural-looking and it holds the two sides of the crack together while the nail grows out. Top coat and colored polish have no structural strength and the crack will simply reopen. Filing the nail down below the split removes healthy nail and is painful once you reach the free edge line.

A client comes in to have a hard gel set removed. What is the correct removal procedure?

• a.Nip the lifted edges with nippers and peel the rest off in one piece
• b.Soak for two minutes, then pry the product off with a metal pusher
• c.Break the seal of the top coat with a file, wrap each nail in acetone-saturated cotton and foil, then gently push off the softened product✓
• d.Soak the hands in warm soapy water and then file the gel off dry

Filing off the shiny sealed surface lets acetone reach the product, and the cotton and foil wrap holds the solvent against the nail until the gel is soft enough to slide off with light pressure. Nipping, peeling or prying takes layers of the nail plate with it and leaves the nail thin, sore and rough. Warm soapy water does not dissolve gel, and filing a whole set off dry generates heat and removes natural nail.

You are trimming a pedicure client's toenails. How should they be cut?

• a.Straight across, then lightly smooth the corners with a file✓
• b.Deeply rounded so the nail follows the curve of the toe
• c.Into a point so the toes fit better in narrow shoes
• d.Down into the corners of the nail grooves to clear out the buildup

Toenails are cut straight across and only the sharp corner is softened with a file, because leaving the corners in place keeps the nail from growing down into the sidewall. Rounding a toenail deeply or cutting into the grooves is the classic cause of an ingrown toenail. A pointed toenail is both fragile and more likely to press into the neighboring toe.

During a pedicure you find a thick, hard callus on the client's heel, and there is a credo blade in the station drawer. What should you do?

• a.Use the credo blade, but only on the dead surface layer
• b.Use the blade while wearing gloves so it is sanitary
• c.Have the client sign a release form and then shave the callus
• d.Leave the blade alone, reduce the callus with a foot file, and refer a severe callus to a podiatrist✓

Credo blades and other razor-type callus shavers are prohibited in California salons because shaving skin is cutting living tissue and is outside a manicurist's scope. A foot file or rasp smooths the callus safely without breaking the skin. Gloves and a signed release do not make a prohibited practice legal, and thick or painful callus belongs to a podiatrist.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

Which massage movement is the light, gliding stroke used to begin and end a relaxing hand and arm massage?

• a.Petrissage
• b.Effleurage✓
• c.Tapotement
• d.Friction

Effleurage is a light, continuous gliding stroke, so it is used to open and close a massage and to keep the client relaxed. Petrissage is kneading and lifting of the tissue, friction is deep circular pressure, and tapotement is a quick tapping or hacking movement. Tapotement is the most stimulating of the four and is never used to settle a client down.

A pedicure client tells you she is diabetic and has lost feeling in her feet. What should you do about the leg and foot massage?

• a.Massage as usual but with lighter pressure
• b.Massage the feet only and skip the legs
• c.Skip the massage and advise her to get clearance from her physician first✓
• d.Use brisk tapotement to stimulate circulation in the numb areas

Diabetes with loss of sensation is a massage contraindication, because the client cannot feel pressure or injury and circulation and healing are impaired, so you skip the massage and send her to her physician. Lighter pressure and limiting it to the feet still apply pressure to compromised tissue. Vigorous tapotement is the most stimulating movement of all and is the worst choice here, just as it would be for high blood pressure, a heart condition, a recent stroke, or a blood clot.

A client's natural nails are thin, peeling and tender after months of aggressive drilling at another salon, although the skin is healthy. She wants a full acrylic set today. What is the best professional response?

• a.Describe what you observe, decline the enhancement today, offer a gentle strengthening manicure, and note it on her record card✓
• b.Apply the acrylic set but keep the product thinner than usual
• c.Tell her she has a nail disease and send her to a doctor
• d.Do the set anyway, since the enhancement will cover the damage

You may describe what you see and recommend a gentler service, and the client record documents the condition and what you advised, which protects both of you. Building product over an already thinned, tender plate causes more damage and likely lifting, and a thinner overlay does not fix a weak foundation. You must never name a disease or diagnose, and the skin here is healthy so there is nothing medical to report.

You are applying the color coat during a polish service. What is the correct stroke pattern for each nail?

• a.One thick stroke straight down the middle of the nail
• b.Small circles worked outward from the center of the nail
• c.Start at the free edge and pull the brush back toward the base of the nail
• d.Three strokes, one down the center and one on each side, then cap the free edge✓

Color is applied in three strokes per coat, center first and then each side, which spreads a thin even film, and stroking the brush across the free edge seals the tip so the polish resists chipping. One thick stroke leaves a heavy ridge in the middle that stays soft and dents. Circles and pulling from the free edge back toward the base drag the polish into the skin and leave streaks.

You finish the hand massage and start to polish, but the polish beads up and slides around on the nail. What step did you skip?

• a.You forgot to apply cuticle oil before polishing
• b.You did not remove the lotion and natural oils from the nail plate with polish remover or a dehydrator✓
• c.You did not soak the nails long enough at the start of the service
• d.You did not buff the nail plate until it was shiny

Polish and every other coating need a clean, dry, oil-free plate, so after the massage the plate is wiped with polish remover or a nail dehydrator before the base coat goes on. Cuticle oil would add more oil and make the problem worse. Extra soaking leaves the plate full of water, and buffing a plate to a high shine makes it smoother and gives the polish even less to hold.

You cure the gel top coat and the surface still feels sticky. What is happening and what should you do?

• a.The gel is under-cured; return the hand to the lamp for five more minutes
• b.The client's nails are oily; soak the hand in warm water and re-cure
• c.It is the normal inhibition layer; wipe it away with a lint-free wipe dampened with cleanser or alcohol✓
• d.The top coat has expired; remove the whole set and start over

Many gels cure with a thin tacky film on top called the inhibition layer, and it is simply wiped off with a lint-free wipe and gel cleanser or alcohol to reveal the shine. This is expected and does not mean the product failed. Extra lamp time will not remove it, soaking the hand in water before wiping ruins the finish, and there is no reason to strip a set that cured correctly.

A client returns after two weeks and the acrylic is lifting at the base of every nail. You remember you carried the product right up against her skin. What should you change next time?

• a.Leave a tiny free margin so the product never touches living skin, and keep the product thinnest at the edges✓
• b.Apply the product thicker at the base so it grips the skin better
• c.File the natural nail thinner first so the product sinks in
• d.Use a coarser abrasive on the enhancement at every fill

Product that touches the eponychium or sidewalls cannot bond to skin, so it breaks away as the skin moves and lifting starts at the base, which is why a hairline margin is left all the way around and the product is feathered thin at every edge. Applying it thicker at the base makes a ledge that catches and pries off. Filing the natural nail thin damages the plate and does not improve adhesion, and a coarser abrasive on the enhancement has nothing to do with lifting at the base.

Your pedicure client leaves and the next client is already waiting. What must be done with the foot spa before the next pedicure?

• a.Drain it and wipe the basin dry with a paper towel
• b.Add fresh hot water and a scoop of disinfectant while the next client soaks
• c.Rinse it with hot water only, since the real disinfection is done at the end of the day
• d.Drain it, remove and clean the screen and the area behind it, scrub and rinse the basin, then refill with water and an EPA-registered disinfectant and circulate it for the full contact time on the label✓

California requires the full clean-and-disinfect cycle between every client: drain, take out the screen or filter and clean behind it, scrub and rinse the basin, then refill and circulate an EPA-registered disinfectant for the contact time the label states. Draining and wiping leaves the debris and biofilm behind the screen untouched. Disinfectant may never be circulating while a client's feet are in the tub, and end-of-day cleaning does not replace the between-client cycle.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

You habitually let a little gel flood onto the skin around the nail and then cure it. A regular client now complains of itching, redness and swelling on her fingertips and eyelids. What is the concern?

• a.Repeated skin contact with uncured gel can cause an allergic sensitization that lasts for life, so product must be kept off the skin✓
• b.The lamp is too weak and she simply needs a longer cure time
• c.She is reacting to the acetone used at the last removal, not to the gel
• d.Redness like this is normal and clears up on its own once the gel is removed

This is the overexposure principle: uncured monomers touching skin over and over can trigger an allergy, and once a person becomes sensitized she is sensitized for life, which is why product is kept off the skin and cured fully. A stronger or longer cure does not undo skin contact that already happened. Symptoms appearing on the eyelids as well as the fingers point to a product allergy carried by touch, not to a solvent used once, and it will not simply go away on its own.

The largest tip in the box is still narrower than your client's nail plate. What should you do?

• a.Force the tip on and fill the gaps at the sidewalls with adhesive
• b.Use a larger size from another tip system, or sculpt the extension on a form instead✓
• c.File the client's sidewalls narrower so the tip will fit
• d.Use the small tip but glue it higher up on the nail plate

A tip must span the nail plate from sidewall to sidewall, so when nothing in the box fits you change systems or build the extension on a form. Forcing a small tip pinches the nail and the glue-filled gaps trap moisture and break down. Filing the client's sidewalls means filing living skin and the natural nail, and gluing the tip higher up puts the contact area and the seam in the wrong place, where it will pop off.

A male client with short nail beds who works with his hands all day asks what shape you recommend. What do you suggest and why?

• a.A pointed stiletto shape, because it makes the finger look longest
• b.A long square shape, because the corners give the nail extra strength
• c.A round shape, because it follows the curve of the fingertip and is least likely to catch or break on short nails✓
• d.A deep oval with a long free edge, because it is the most elegant look

Round is the standard shape for short nails and for clients who work with their hands, because it mirrors the fingertip, leaves no corner to snag and needs almost no free edge. A pointed shape is the weakest of all because the stress is narrowed to a single point. A long square has corners that catch on tools and gloves, and a deep oval needs length this client does not have.

A client with a new full set of liquid-and-powder enhancements asks how often she needs to come back. What do you tell her?

• a.Only when a nail actually breaks or lifts
• b.Every six to eight weeks
• c.Once a week, for a brand new set each time
• d.About every two to three weeks for a fill and rebalance, because new growth moves the apex and the stress area✓

Nails grow roughly a tenth of an inch a month, so in two to three weeks the apex and stress area have shifted forward and the enhancement becomes top-heavy and prone to cracking, which is what a fill and rebalance corrects. Waiting six to eight weeks or until something breaks allows lifting where moisture and bacteria can collect. A whole new set every week is unnecessary and would destroy the natural nail from repeated removal.

A client tells you that months ago she slammed her finger in a car door, and ever since, the new nail has grown in with a permanent ridge and a twisted shape. Which nail structure was most likely damaged?

• a.The nail bed
• b.The hyponychium
• c.The matrix✓
• d.The free edge

The matrix is the only tissue that produces new nail cells, so an injury there can change the shape of every nail that grows out afterward, sometimes permanently. The nail bed only supports the plate as it slides forward; it does not manufacture new nail. The hyponychium and the free edge are at the fingertip end, far from where new nail is formed.

A client points at the whitish half-moon shape at the base of her thumbnail and asks you what it is. What is the most accurate answer?

• a.It is the lunula, the part of the matrix that can be seen through the nail plate✓
• b.It is air trapped underneath the nail plate
• c.It is a vitamin deficiency showing through the nail
• d.It is the hyponychium showing through from underneath

The lunula is simply the front portion of the matrix that lies close enough to the surface to be visible, which is why it looks whiter than the rest of the nail. It is not trapped air, and it is not a health or vitamin sign; a manicurist may never explain a nail feature as a medical or nutritional condition. The hyponychium sits under the free edge at the fingertip, not at the base of the nail.

A nervous first-time client asks why she cannot feel anything when you file the surface of her nail. What is the correct explanation?

• a.The nail plate is living skin, but the nerves stop at the free edge
• b.The nail plate is fed by the eponychium, which keeps it numb
• c.The nail plate is a thin layer of cartilage with no blood supply
• d.The nail plate is made of hardened, non-living keratin cells, so it contains no nerves✓

The nail plate is a hardened sheet of keratin made of dead cells, so it has no nerves and no blood vessels of its own and filing its surface is not felt. It is not living skin and it is not cartilage. The eponychium is living skin at the base of the nail and has nothing to do with numbing the plate; if a client does feel pain, you are filing too deeply or touching living tissue and must stop.

You remove a client's polish and notice that the natural nail looks pink through the plate. What is responsible for that pink color?

• a.The keratin of the nail plate is naturally pink
• b.The nail bed under the plate is living tissue rich in blood vessels✓
• c.The lunula runs the full length of the nail
• d.Cuticle tissue stains the plate pink over time

The nail bed is the living skin directly under the nail plate; it is full of blood vessels and nerves, and that blood supply is what shows through as pink. The plate itself is colorless dead keratin, so it takes its color from what is underneath. The lunula is only the visible portion of the matrix at the base, and dead cuticle tissue does not tint the nail.

A client asks you to cut all of her cuticle off and points to the band of living skin at the base of the nail plate. What must you do?

• a.Cut it carefully with sharp nippers because the client requested it
• b.Trim only the top layer of that living skin and leave the rest
• c.Explain that this living skin is the eponychium and may not be cut, then gently push it back and remove only loose dead tissue✓
• d.Soak the finger in acetone until the skin dissolves

The band of living skin at the base of the plate is the eponychium, and cutting living tissue is outside a California manicurist's scope of practice no matter what the client asks for. Cutting it, even partially, breaks the seal that keeps bacteria out and invites infection. Only loose dead tissue sitting on the nail plate may be removed, and acetone does not and should not be used to dissolve skin.CA Business & Professions Code §7320

Which tissue is the true cuticle, the only tissue a manicurist may gently remove?

• a.The dead, colorless tissue that clings to the surface of the nail plate✓
• b.The living skin at the base of the nail plate
• c.The skin that seals underneath the free edge
• d.The wall of skin along each side of the nail

The true cuticle is dead, colorless tissue shed onto the surface of the nail plate, and because it is not living it may be softened and gently removed. The living skin at the base is the eponychium, the seal under the free edge is the hyponychium, and the skin along the sides is the nail fold or sidewall; all three are living and may never be cut. Confusing the eponychium with the cuticle is the most common reason technicians cut skin they should not touch.

A client asks you to dig deep underneath the free edge of her nails with a metal tool so they will be really clean. Why should you refuse?

• a.Because the free edge itself contains nerve endings and will bleed
• b.Because you would break the hyponychium, the skin seal under the free edge that keeps bacteria out✓
• c.Because the matrix is located directly under the free edge
• d.Because metal tools may never touch a natural nail plate

The hyponychium is the living skin that seals the space between the free edge and the fingertip, and it is a barrier against bacteria and fungus. Digging under the free edge tears that seal and creates a direct entry point for infection, so clean gently and only at the surface. The free edge is dead keratin with no nerves, the matrix is at the base of the nail rather than the tip, and disinfected metal implements are allowed when used correctly.

What is the function of the nail grooves and the nail folds (sidewalls)?

• a.They produce the new nail cells at the base of the nail
• b.They seal the nail plate so water cannot pass under it
• c.They deliver the blood supply directly into the nail plate
• d.They form the tracks and folds of skin that hold the nail plate and guide it as it grows forward✓

The nail grooves are the narrow tracks on each side of the nail bed, and the nail folds or sidewalls are the skin that overlaps them; together they hold the plate in place and steer its growth toward the fingertip. New nail cells come only from the matrix, the seal under the free edge is the hyponychium, and the plate itself has no blood supply because it is dead keratin. Filing or cutting into the sidewalls damages living skin and can lead to an ingrown nail.

A client has a dark stain on her natural nail close to the base and asks how long it will take to grow out completely. Based on normal nail growth, what should you tell her?

• a.About 4 to 6 months, because a fingernail grows roughly 1/10 inch (about 2.5 mm) per month✓
• b.About 3 to 4 weeks, since the whole nail is replaced every month
• c.About 2 years, the same as any nail on the body
• d.It will never grow out, because the stain is in the nail bed

A healthy fingernail grows about 1/10 inch, or roughly 2.5 mm, each month, so it takes about four to six months for a completely new plate to replace the old one. A nail is nowhere near replaced in a month, and two years is far longer than even a toenail needs. Telling her the stain is in the nail bed would be guessing at a medical explanation, which a manicurist may not do.

A client lost part of her big toenail after dropping something on her foot and wants to know how long it will take for a completely new toenail to replace it. What is the best answer?

• a.About 4 to 6 weeks
• b.About 4 to 6 months, the same as a fingernail
• c.About 9 to 12 months, because toenails grow more slowly than fingernails✓
• d.Toenails never fully replace themselves once they are lost

Toenails grow noticeably more slowly than fingernails and generally need about nine to twelve months to be completely replaced. Four to six weeks is nowhere near enough time, and four to six months is the timeline for a fingernail, not a toenail. Toenails do regrow as long as the matrix was not permanently destroyed, but growth also slows with age, poor circulation and illness.

A client removes her sandals and you see a thickened, yellow-green toenail that is crumbling at the edge and gives off a foul odor. What must you do?

• a.Buff the nail thin, disinfect extra well, and continue the pedicure
• b.Politely explain that you cannot perform the service and recommend that she see a physician✓
• c.Tell her she has a nail fungus and sell her an antifungal product from the retail shelf
• d.Service the other nine toes and simply skip that one

A thickened, discolored, crumbling nail with an odor shows signs of infection, and California manicurists may not service an infected nail. The correct response is to politely explain that you cannot perform the service and recommend she see a physician, without naming a disease. Buffing or filing it spreads the organism through the dust and around the salon, working around it still exposes the tools, the water and the next client, and naming the condition and selling a treatment is diagnosing and treating, which is outside your scope.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

A regular client sits down and the skin around one fingernail is red, shiny, swollen and painful, with a small amount of pus at the nail fold. What is the correct action?

• a.Press gently to release the pus, then disinfect the area and continue
• b.Work around that finger and complete the other nine nails
• c.Tell her it is paronychia and that she needs an antibiotic
• d.Politely explain that you cannot perform the service and recommend that she see a physician✓

Redness, swelling, pain and pus are classic signs of an active infection, and a manicurist may not service infected skin or nails. You should politely explain that you cannot perform the service and recommend she see a physician. Squeezing pus spreads bacteria and can drive the infection deeper, working around the finger still puts your implements and the next client at risk, and naming the condition and recommending an antibiotic is a medical diagnosis you are not licensed to make.CA Business & Professions Code §7320

During a pedicure consultation you notice that the side of a client's big toe is swollen, warm and oozing fluid where the nail has grown down into the skin. What must you do?

• a.Politely explain that you cannot perform the service and recommend that she see a physician✓
• b.Lift the nail corner with a metal pusher and pack cotton underneath it
• c.Cut a V-shaped notch in the center of the nail so the corner will grow out
• d.Trim the ingrown corner out with nippers and apply antiseptic

Swelling, heat and discharge mean the ingrown toenail is already infected, and servicing infected tissue is prohibited, so you politely decline and recommend a physician or podiatrist. Digging the corner out or packing cotton under the nail means working on living, infected tissue and can push bacteria deeper. Cutting a V-notch does nothing to change how the nail grows, since growth comes only from the matrix, and applying antiseptic to an infection is treatment, which is outside a manicurist's scope.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

A client's foot has itchy, peeling skin between the toes with raw, weeping cracks in it. What is the correct response?

• a.Soak the foot longer in the disinfected spa so the skin softens first
• b.Use a foot file on the peeling skin, then finish the pedicure while wearing gloves
• c.Politely explain that you cannot perform the service and recommend that she see a physician✓
• d.Apply an antifungal cream from your retail shelf and rebook her for next week

Broken, weeping skin is an open door for infection and is also a sign of a contagious condition, so no service may be performed and you politely refer her to a physician. Soaking or filing that skin spreads the organism into the tub, the file and the towels, and gloves protect you but do nothing to protect the client or the next client. Applying an antifungal product is treating a condition, and a manicurist may not treat or diagnose anything.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

A teenage client is worried about small white spots scattered across several of her fingernails. The nail folds and surrounding skin look completely healthy. What should you do?

• a.Refuse the service, because white spots always mean a fungal infection
• b.Tell her the spots mean she is low on calcium and should take a supplement
• c.Scrape the spots off the nail plate with a metal pusher
• d.Explain that white spots (leukonychia) usually come from minor injury to the matrix, then continue the service as normal✓

Leukonychia is a harmless disorder, usually caused by a small bump or injury at the matrix, and because there is no infection you may service the nails normally. It is not a fungal infection, so refusing service is not needed, and the spots grow out on their own. Telling a client she is low on calcium is offering a medical or nutritional opinion you are not licensed to give, and the spots are inside the plate so scraping only thins and damages the nail.

A client has living skin that has grown forward and is stuck tightly to the surface of the nail plate, a condition called pterygium. What is the correct way to handle it?

• a.Cut the attached skin away with nippers so the nail looks longer
• b.Do not cut it; care for the area gently, keep it conditioned with oil, and refer her to a physician if it is severe✓
• c.File it off the nail plate with a coarse abrasive
• d.Leave an acid cuticle remover on it for twenty minutes until the skin releases

Pterygium is living skin, not dead cuticle, so cutting or filing it is cutting living tissue and is outside a manicurist's scope; it also makes the condition worse and can cause bleeding and infection. The correct approach is gentle care with oil and massage, and a referral to a physician if the growth is severe. A strong cuticle remover left on for twenty minutes will irritate and burn the skin without solving anything.CA Business & Professions Code §7320

A client who spent two weeks in the hospital with a high fever now has a deep horizontal groove running across every fingernail at about the same place, and she asks you what disease she has. How should you respond?

• a.Explain that grooves like these can appear after an illness because nail growth slows, that you are not permitted to diagnose, and that her doctor can answer health questions, then service the nails gently✓
• b.Tell her she has a serious internal disease and should stop getting manicures
• c.Diagnose it as a fungal infection and refuse all service
• d.Buff the grooves completely flat so the nails look smooth again

Horizontal grooves across the nails, known as Beau's lines, commonly follow a fever, illness or serious stress that temporarily slowed the matrix, and the nail is not infected, so it may be serviced gently. Nail changes can reflect general health, but a manicurist may never name a disease or make a diagnosis; that is the physician's job. Buffing the grooves flat would thin the plate and weaken it, and calling it a fungal infection is both wrong and a diagnosis you cannot make.CA Business & Professions Code §7320

How many bones are found in the wrist, the palm and the fingers of one hand?

• a.5 carpals in the wrist, 8 metacarpals in the palm and 12 phalanges in the fingers
• b.8 carpals in the wrist, 5 metacarpals in the palm and 14 phalanges in the fingers✓
• c.7 carpals in the wrist, 5 metacarpals in the palm and 26 phalanges in the fingers
• d.8 carpals in the wrist, 14 metacarpals in the palm and 5 phalanges in the fingers

Each hand has 8 carpals in the wrist, 5 metacarpals in the palm and 14 phalanges in the fingers, because the thumb has two phalanges and each of the other four fingers has three. The forearm you massage above the wrist has only two bones, the radius on the thumb side and the ulna on the little-finger side. The other choices simply swap those numbers around; 7 is the number of tarsals in the foot, not carpals in the wrist.

You are massaging a client's lower leg and foot during a pedicure. Which statement about the bones you are working over is correct?

• a.The lower leg has a single bone called the fibula, and the foot has 14 bones in total
• b.The lower leg contains the radius and the ulna, and the foot has 26 bones
• c.The tibia is the small outer bone and the fibula is the large shin bone, and the foot has 19 bones
• d.The tibia is the large inner shin bone and the fibula is the smaller outer bone, and the foot has 26 bones: 7 tarsals, 5 metatarsals and 14 phalanges✓

The lower leg has two bones, the larger tibia along the inner shin and the thinner fibula on the outer side, and each foot has 26 bones made up of 7 tarsals, 5 metatarsals and 14 phalanges. The radius and ulna are forearm bones, not leg bones. The remaining choices either drop a bone from the lower leg or reverse the sizes of the tibia and fibula.

While massaging a client's lower leg you work the muscle that runs down the front of the shin and lifts the foot upward at the ankle. Which muscle is it?

• a.The gastrocnemius
• b.The soleus
• c.The tibialis anterior✓
• d.The peroneus longus

The tibialis anterior lies along the front of the shin and pulls the foot upward, so it is the muscle you feel there. The gastrocnemius and the soleus are the calf muscles at the back of the leg and they point the foot downward, while the peroneus longus turns the foot outward. In the hand, remember that flexors bend the fingers, extensors straighten them, abductors spread them apart and adductors draw them back together.

In a liquid-and-powder (acrylic) service, how do the products actually harden?

• a.The liquid is the polymer and the powder is the monomer, and the bead hardens only after it goes under an LED lamp.
• b.The liquid monomer and the powder polymer, with an initiator, join together in polymerization — a heat-releasing (exothermic) reaction that cures without any lamp.✓
• c.The powder carries photoinitiators, so the bead will not form chains until UV light reaches it.
• d.Polymerization is a cooling reaction, so a properly mixed bead feels cold to the client as it sets.

Liquid-and-powder systems are a monomer (liquid) plus a polymer (powder) with a catalyst/initiator; when they meet, the small monomer units link into long chains in polymerization. That reaction gives off heat, which is why a client may feel warmth, and it needs no lamp at all. The choices that reverse monomer and polymer, or that require a lamp or photoinitiators, describe UV/LED gel, not liquid-and-powder; and polymerization releases heat rather than absorbing it.

You cure a client's gel in a lamp that was not made for that gel line. Within a week the gel is lifting at the edges and she says her fingertips itch. What is the most likely cause?

• a.The photoinitiators in the gel never received the wavelength and lamp output they need, so the coating stayed under-cured — under-cured gel lifts and the uncured chemical on the skin can cause sensitization.✓
• b.The gel was cured too thoroughly, which always makes gel brittle and makes it peel off in a week.
• c.Gel does not really need a lamp; the lifting comes from the base coat alone and the itching is unrelated to the product.
• d.Lifting and itching together prove that the client is allergic to acetone.

UV/LED gel only polymerizes when its photoinitiators are struck by the correct wavelength and intensity, so the wrong lamp leaves the coating partly liquid inside. Under-cured gel bonds poorly and lifts, and the uncured ingredients that reach the skin are exactly what drives allergic sensitization. Over-curing is not what caused this, gel absolutely does require a matched lamp, and acetone was not part of this service.

A newly hired technician pours acid (methacrylic acid) primer into an open dish and brushes it over the whole nail and the surrounding skin so the acrylic will 'really stick.' What should you tell her?

• a.Acid primer is harmless on skin; only breathing the vapor is a concern.
• b.Flooding the skin is fine as long as she wipes the skin off after the enhancement has cured.
• c.She should use even more primer, because more primer always means less lifting.
• d.Acid primer is corrosive: wear gloves and eye protection, apply a sparing amount to the natural nail plate only, and never let it touch skin.✓

Methacrylic acid primer is corrosive to skin and eyes, so it calls for gloves, eye protection and a very small amount applied only where the enhancement will sit on the natural nail. Getting it on the skin can burn and it also feeds allergic sensitization, so wiping it off later does not undo the contact. More primer does not improve retention — proper prep and a thin, sparing application do; a non-acid primer is the gentler alternative.

A client arrives wearing gel polish and hard enhancements and wants everything removed today. Which statement about the removal solvents is correct?

• a.Ethyl acetate (non-acetone) removes gel and enhancements faster than acetone does.
• b.Acetone is non-flammable, so an open bowl of it can safely sit next to a lit candle on the table.
• c.Acetone dissolves polish, gel and enhancements quickly, while ethyl acetate (non-acetone) is slower and gentler; acetone is flammable and drying, so keep it capped and away from any flame.✓
• d.Non-acetone remover is the stronger product and should be used on enhancements, while acetone is only for plain polish.

Acetone is the fast, aggressive solvent that will break down polish, gel and acrylic, but it is flammable and it strips oils from the nail and skin, so it belongs in a closed container away from heat and flame. Ethyl acetate is the slower, gentler non-acetone solvent used mainly on regular polish. The options calling non-acetone faster or stronger have it backwards, and calling acetone non-flammable is a serious safety error.

While applying nail tips you squeeze a large drop of adhesive onto each tip so it will 'hold longer.' What actually happens?

• a.Tip and wrap adhesive is a cyanoacrylate that bonds best in a thin layer; too much floods out onto the skin, traps air pockets, sets slowly and unevenly, and the tip lifts or pops off.✓
• b.A thicker layer of cyanoacrylate always creates a stronger, longer-lasting bond than a thin one.
• c.The extra adhesive acts as a primer, so no other nail preparation is needed.
• d.Cyanoacrylate only sets under a UV lamp, so how much you use makes no difference.

Cyanoacrylate adhesive cures fastest and strongest as a thin film between two close-fitting surfaces, so a thin even layer is what holds a tip on. A heavy drop squeezes out onto the skin, leaves air bubbles under the tip and cures unevenly, which is a common cause of lifting and popped-off tips. Adhesive is not a primer and does not replace prep, and cyanoacrylate cures chemically — often with an activator — not under a lamp.

A client's enhancements lift within a few days every single time. Her nail plates look shiny and feel oily. What is the correct way to improve adhesion?

• a.File the natural nail plate down thin until the product finally holds.
• b.Clean and dry the plate, remove surface oil and moisture with a dehydrator, and lightly buff off the shine with an appropriate abrasive before applying product.✓
• c.Skip washing her hands so the natural oils help the product grip the plate.
• d.Apply a much thicker bead of product so its weight can overpower the oil.

Adhesion needs a clean, dry, oil-free surface plus a little mechanical grip, so the correct sequence is cleaning, a dehydrator to take off surface moisture and oil, and a light roughening of the shine. Filing the natural nail thin to force a bond weakens and damages the plate and is never acceptable. Leaving oils in place is exactly what causes lifting, and a thicker bead only adds weight and stress to a bond that was never clean to begin with.

What does the overexposure principle mean for a nail technician?

• a.Only products labeled as toxic can cause a reaction, so products considered safe may freely touch the skin.
• b.One single splash of any product permanently sensitizes you, so an accidental spill ends a nail career.
• c.Repeated or prolonged contact with a product — even one that is safe in normal use — can build up a sensitivity, and once you become allergic you stay allergic, so keep products off the skin and use gloves and good ventilation.✓
• d.Overexposure only matters for clients, because technicians build up immunity to the products over time.

Overexposure describes a dose problem: the amount and the number of times a chemical touches you or is breathed in, day after day, is what creates sensitization. Once a person is sensitized to a monomer or gel ingredient, the allergy is generally lifelong, so prevention means keeping product off the skin, wearing gloves and ventilating at the source. It is not limited to 'toxic' products, it is not usually caused by one splash, and technicians do not develop immunity — their risk goes up with exposure, not down.

A regular gel client returns with itching, redness, swelling and small blisters on the skin around several nails and on her eyelids. Looking back, gel often flooded her sidewalls and cuticle area. What should you do?

• a.Repeat the same gel service but cure it twice as long to burn off whatever is irritating her.
• b.Tell her it is a nail fungus and sell her an antifungal product to use at home.
• c.Switch her to a stronger acid primer so the primer seals the skin from the gel.
• d.Stop the gel service, explain that what you see looks like an allergic contact reaction most likely from product touching the skin, refer her to a physician, and afterward keep product off the skin and cure fully.✓

Itching, redness, swelling and blistering on the fingers, eyelids or face is the classic pattern of allergic sensitization to a nail product, and gel flooding the skin plus under-curing is the usual cause. The manicurist's job is to stop the service, describe what is seen without diagnosing, refer the client to a physician, and correct the technique so product never touches skin. Curing longer, calling it a fungus and selling a treatment, or adding a corrosive acid primer to skin all make the exposure worse.

During an inspection the inspector finds monomer poured into an unlabeled sports-drink bottle, sitting open on a shelf next to the salon's water heater. What is wrong with this?

• a.Products must stay in their original closed, labeled containers, stored cool and away from heat and open flame — never decanted into unlabeled or food and drink containers.✓
• b.Nothing is wrong, because the technician who poured it knows what is in the bottle.
• c.It is acceptable as long as the bottle is used up within a week and then thrown away.
• d.Only disinfectants have to be labeled; professional nail products are exempt from labeling.

Every chemical in the salon has to be identifiable to employees and to the inspector, which is why products stay in their original labeled containers, kept closed, cool and away from heat and flame. A drink bottle is the worst possible choice because someone can swallow the contents, and an unlabeled container also defeats the right-to-know rules and the matching Safety Data Sheet. Personal knowledge, short-term use, and the idea that only disinfectants need labels are all incorrect.Cal/OSHA Hazard Communication Standard (8 CCR §5194)

Which statement about pH is correct for nail and skin care?

• a.Pure water is strongly acidic at pH 7, and the natural nail plate is alkaline.
• b.Pure water is neutral at pH 7, while the skin and the natural nail plate are slightly acidic; strongly alkaline products swell and soften keratin.✓
• c.The higher the pH climbs, the harder and tighter the keratin of the nail becomes.
• d.pH has no effect on the nail plate at all, because the plate is made of dead keratin.

On the pH scale, 7 is neutral — that is pure water — and the skin and nail plate normally sit slightly below 7, on the acidic side. Products that are strongly alkaline raise the pH, causing keratin to absorb water, swell and soften, which is why harsh alkaline products can leave the plate weak or over-softened. Water is not acidic, a high pH softens rather than hardens keratin, and even dead keratin still reacts chemically to pH.

Which agency issues and regulates manicurist licenses in California, and which law governs that licensing?

• a.The California Department of Public Health, under the state sanitation code for nail salons
• b.The county health department where the salon is located, under local ordinance
• c.The Board of Barbering and Cosmetology, part of the Department of Consumer Affairs, under the Barbering and Cosmetology Act✓
• d.Cal/OSHA, under the state workplace safety code

Manicurists are licensed, renewed and inspected by the Board of Barbering and Cosmetology, which operates under the Department of Consumer Affairs, and the Barbering and Cosmetology Act is the governing statute. The county health department and the Department of Public Health regulate other kinds of facilities, not nail licensing. Cal/OSHA covers worker safety topics such as chemical labeling and bloodborne pathogens, but it does not issue your manicurist license.California Barbering and Cosmetology Act (B&P Code §7301 et seq.)

What must a person complete in order to qualify for a California manicurist license?

• a.A board-approved 400-hour manicurist course or an approved apprenticeship, be at least 17 years old and have completed the 10th grade, and pass the written licensing examination✓
• b.A 600-hour course, be at least 18 years old, hold a high school diploma, and pass a practical examination only
• c.Two years of paid work under a licensed manicurist plus employer letters, with no examination required
• d.Any nail course offered by a product manufacturer, plus payment of the license fee

California requires the approved 400-hour manicurist course or an approved apprenticeship, a minimum age of 17 with completion of the 10th grade, and a passing score on the written licensing exam. The 600-hour, 18-year-old and high school diploma answer overstates the requirements and drops the written exam. On-the-job time alone or a manufacturer's class does not substitute for approved training and the exam.California Barbering and Cosmetology Act (B&P Code §7301 et seq.)

You are hired at a busy salon and realize your manicurist license expired eight months ago, but you have kept taking clients the whole time. Which statement is correct?

• a.There is a one-year grace period, so you may keep working as long as you renew before the year ends
• b.Your license renews automatically as long as the salon holds a current establishment license
• c.Manicurist licenses are renewed every four years, so nothing was due yet
• d.Licenses must be renewed every two years, and working on an expired license is unlicensed practice that can bring a citation, a fine and discipline✓

A California manicurist license must be renewed every two years, and once it expires you have no authority to work — every service performed after that date is unlicensed practice and can result in a citation, a fine and action against your license. There is no grace period that lets you keep working, and the salon's establishment license covers the business, not the individual worker. The four-year renewal cycle is simply wrong.California Barbering and Cosmetology Act (B&P Code §7301 et seq.)

On your first day at a new salon, the owner collects your license and locks it in a binder in the back office "so nothing happens to it." What does California law require?

• a.The license only needs to be produced if an inspector specifically asks to see it
• b.Your license must be displayed in plain view in the establishment where you are working✓
• c.Keeping the original safe at home and a photocopy in the office satisfies the requirement
• d.Only the establishment license must be posted; individual worker licenses stay in the personnel file

Each licensee's license must be posted in plain view at the establishment where that person works, so clients and inspectors can see it without asking. Storing it in a back-office binder, at home, or producing it only on request does not meet the display requirement. The establishment license must also be posted, but it does not replace the individual manicurist licenses.California Barbering and Cosmetology Act (B&P Code §7301 et seq.)

During a pedicure your client asks you to shave down her thick heel callus with a credo blade, and then to wax her upper lip while the polish dries. How should you respond?

• a.Do both, since a manicurist license covers the hands, the feet and the skin
• b.Do the lip wax because it is a simple skin service, but refuse the blade
• c.Decline both, explain that a manicurist may not cut living tissue and may not perform skin services beyond the hands and arms to the elbow and the feet and legs to the knee, smooth the callus with a foot file, and refer her elsewhere✓
• d.Do both if she signs a waiver accepting the risk

A manicurist's scope is caring for the nails of the hands and feet plus cleansing, massaging and beautifying the hands and arms up to the elbow and the feet and legs up to the knee, so facial waxing is outside that scope. Razor-type callus shavers are prohibited because cutting living skin is not permitted; reduce callus with a foot file and send severe callus to a podiatrist. A client waiver cannot give you authority the license does not grant, and the lip wax is not legal simply because it seems minor.CA Business & Professions Code §7320

A nail salon is sold to a new owner, who also moves the shop two blocks down the street. What do the establishment rules require?

• a.Only the individual licenses matter; the shop itself does not need a license
• b.The existing establishment license transfers automatically with the business to the new owner
• c.A change of address can simply be reported whenever the next renewal comes due
• d.The salon must hold its own current establishment license, and the Board must be notified of the change of ownership and the change of location✓

The business itself has to be licensed as an establishment in addition to every person working there, and the Board must be notified when the establishment changes ownership or moves to a new address. An establishment license does not simply travel with the sale, and waiting until the next renewal to report a move leaves the salon operating outside its licensed address. Saying only individual licenses matter ignores the establishment licensing requirement entirely.California Barbering and Cosmetology Act (B&P Code §7301 et seq.)

It is a packed Saturday afternoon and a Board inspector walks into the salon without an appointment. What is the correct response, and what will the inspector be looking at?

• a.Let the inspector in and cooperate — inspections are unannounced, and the inspector will check disinfection containers and solutions, dated foot spa cleaning records, posted licenses, labeled product containers and any prohibited products✓
• b.Ask the inspector to schedule an appointment and come back on a slower day, since inspections must be arranged in advance
• c.Cooperate, but understand the inspector only verifies that the establishment license is current and nothing operational
• d.Refuse entry unless the inspector produces a search warrant

Board inspections are unannounced, and the inspector may look at your disinfection setup and solution, the dated foot spa cleaning logs, whether licenses are displayed, whether product containers are closed and labeled, and whether any prohibited item such as MMA or a credo blade is on site. Inspections are not scheduled around your appointment book, and no warrant is required for a routine inspection of a licensed salon. The inspection covers day-to-day practice, not just paperwork on the wall.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

An inspector finds used metal nippers sitting loose in a drawer, no cleaning records for any of the four foot spas, and a credo blade in a technician's station. What can result?

• a.A first inspection can only produce a verbal warning, so no money penalty is possible
• b.The Board can issue citations with fines for the violations, and repeated or serious violations can lead to suspension or revocation of a license✓
• c.Only the salon owner can be cited; an individual manicurist is never personally penalized
• d.Fines apply only if a client was actually injured and filed a complaint

Health and safety violations found at an inspection can be cited with fines, and a pattern of violations or a serious one can lead to suspension or revocation of the establishment or individual license. Enforcement does not wait for a client to be hurt or to complain — the violation itself is enough. Both the establishment and the individual licensee can be held responsible, and there is no rule limiting a first inspection to a verbal warning.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

How is a client supposed to learn where to file a complaint about a nail salon, and what records must the salon be able to show?

• a.Complaints go to the county health department, and no notice has to be posted in the salon
• b.The notice is only required in salons with more than five employees
• c.The salon must display the Board's required consumer notice with the Board's contact information, and must keep required records such as the dated foot spa cleaning logs available for the inspector✓
• d.The salon must hand every client a printed complaint form at the end of each service

Every licensed establishment must post the Board's consumer notice showing how to reach the Board, so a client who is unhappy or injured knows exactly where to file a complaint, and the salon must be able to produce required records such as the dated cleaning log for each foot spa. Complaints about licensed nail salons go to the Board, not the county health department. The posting requirement does not depend on how many people work there, and there is no rule requiring a complaint form be handed out with every service.California Barbering and Cosmetology Act (B&P Code §7301 et seq.)

A friend whose manicurist license lapsed asks to take walk-in clients at your station and to use your license number if anyone asks. What should you do?

• a.Allow it as long as you stay in the salon and directly supervise her work
• b.Allow it for up to 30 days while her renewal application is being processed
• c.Allow it if the salon owner approves the arrangement in writing
• d.Refuse — every person performing nail services must hold their own current license, and letting someone work under yours is unlicensed practice for which both of you can be cited and your own license can be suspended or revoked✓

Each person who performs nail services must personally hold a current California license, so a lapsed licensee working under your number is unlicensed practice and you are helping it happen. Supervision, a pending renewal and the owner's written blessing change nothing, because none of them creates licensed authority. Both of you can be cited and fined, and your own license can face suspension or revocation.California Barbering and Cosmetology Act (B&P Code §7301 et seq.)
