Continue in the practice tool above to load more questions, 50 at a time.

Question 1Infection Control, Sanitation, and Safety

Which step must be completed before reusable metal implements are placed in a disinfecting solution?

  1. Wipe them with a paper towel and store them in a drawer
  2. Wash them with soap and water and dry them thoroughly Correct answer.
  3. Rinse them briefly under cool running water
  4. Soak them for twice the label contact time

Explanation

Organic material such as skin cells, oil, and product residue shields microorganisms and can inactivate a disinfectant. Implements must therefore be washed with soap and water, rinsed, and dried before immersion. The labeled contact time is only meaningful once the surface is clean.

Question 2Infection Control, Sanitation, and Safety

Which item must be thrown away after it is used on a single client?

  1. A metal cuticle pusher
  2. An emery board Correct answer.
  3. Stainless steel cuticle nippers
  4. A glass disinfectant tray

Explanation

Porous items such as emery boards, buffer blocks, and wooden sticks absorb moisture and debris and cannot be reliably cleaned and disinfected, so they are single-use. Nonporous items like stainless steel and glass can be cleaned, disinfected, and reused.

Question 3Infection Control, Sanitation, and Safety

A nail technician should wash their hands with soap and warm water at which time?

  1. Only when the hands are visibly soiled
  2. Only at the beginning of the day and at closing time
  3. Only after working on a client with a known infection
  4. Before and after each client, and after gloves Correct answer.

Explanation

Hand hygiene is performed before and after every client contact and again after removing gloves, because gloves can develop unnoticed tears and hands can pick up organisms during removal. Visible soil is not required for transmission to occur.

Question 4Infection Control, Sanitation, and Safety

Gloves worn during a manicure must be changed

  1. Every third client to conserve supplies
  2. Once per shift, at the end of the day
  3. Between clients and any time they tear or become contaminated Correct answer.
  4. Only after handling a client with a visible infection

Explanation

Gloves are single-use barriers that must be replaced between clients and immediately whenever they are torn, punctured, or soiled. A damaged glove no longer blocks the transfer of blood and microorganisms.

Question 5Infection Control, Sanitation, and Safety

Which practice is correct for cloth towels used in the salon?

  1. Spray used towels with disinfectant and let them air-dry
  2. Hang damp towels in a closed cabinet for reuse
  3. Use a clean towel for each client and launder used towels in hot water with detergent Correct answer.
  4. Shake off the dust and reuse for the next client

Explanation

Towels contact skin and nail debris, so a clean one is used per client and soiled linens are laundered in hot water with detergent. Damp or reused linens support microbial growth.

Question 6Infection Control, Sanitation, and Safety

In the United States, a disinfectant used in a nail salon must carry a registration number from which agency?

  1. The Environmental Protection Agency Correct answer.
  2. The Centers for Disease Control and Prevention
  3. The Occupational Safety and Health Administration
  4. The Food and Drug Administration

Explanation

Disinfectants marketed as germicides are pesticides and must be registered with the Environmental Protection Agency, which reviews the label claims. The registration number on the label confirms the product's claims were reviewed.

Question 7Infection Control, Sanitation, and Safety

Which practice keeps the work area safe and sanitary?

  1. Setting a coffee cup beside the monomer bottle
  2. Keeping food and drinks away from implements and product bottles Correct answer.
  3. Eating a snack at the table between clients
  4. Sharing a drink with a client during the service

Explanation

Food and drink are kept out of the service area so that chemicals, dust, and microorganisms cannot contaminate them and so spills do not damage products. Separate break areas protect both the technician and the client.

Question 8Infection Control, Sanitation, and Safety

How should clean, disinfected implements be stored?

  1. In the same bag as used files
  2. In an open tray on the worktable
  3. In a used towel on the counter
  4. In a clean, covered container or closed drawer Correct answer.

Explanation

Disinfected implements must be protected from dust, spills, and airborne organisms until use, which requires a clean, closed container. Open or shared storage recontaminates the tools before the next client.

Question 9Infection Control, Sanitation, and Safety

What determines how long implements must stay submerged in a disinfectant?

  1. The number of clients served that day
  2. A fixed ten minutes for every product on the market
  3. The manufacturer's label directions for that product Correct answer.
  4. The preference of the technician on duty

Explanation

Kill times differ among disinfectant chemistries, so the labeled contact time is the only reliable instruction for that specific product. Using a shorter soak than directed means the product has not met its labeled claims.

Question 10Infection Control, Sanitation, and Safety

An implement has just been used near a client's bleeding cuticle. Which disinfectant is appropriate?

  1. An EPA-registered hospital disinfectant labeled tuberculocidal Correct answer.
  2. A bottle of 70% isopropyl alcohol
  3. A soap-based hand cleaner
  4. A sanitizer labeled for food-contact surfaces

Explanation

Items contaminated with blood or other body fluids require a hospital-grade disinfectant with a tuberculocidal claim, because the tubercle organism is more resistant than many others. Plain cleaners, food-contact sanitizers, and generic alcohol do not carry that claim.

Question 11Infection Control, Sanitation, and Safety

Which process destroys bacterial spores as well as ordinary bacteria and viruses?

  1. Soaking in a quaternary ammonium solution
  2. Wiping with a sanitizing wipe
  3. Steam sterilization in an autoclave Correct answer.
  4. Washing with soap and cool water

Explanation

Sterilization destroys all microbial life, including highly resistant bacterial spores, and steam under pressure in an autoclave is the standard method in salons. Disinfectants kill many organisms but do not reliably eliminate spores.

Question 12Infection Control, Sanitation, and Safety

After each pedicure, the foot spa basin must be

  1. Left filled with water and a few drops of bleach
  2. Rinsed and refilled for the next client
  3. Drained, cleaned with soap and water, then disinfected with an EPA-registered product per its label Correct answer.
  4. Wiped with a dry towel and left overnight

Explanation

Whirlpool basins harbor debris and biofilm, so they are drained, scrubbed clean, and then disinfected with an EPA-registered product used exactly as labeled. The full cleaning step is required before the disinfectant is applied.

Question 13Infection Control, Sanitation, and Safety

A client arrives with thick, yellowed, crumbling toenails. What is the appropriate response?

  1. Decline the service and refer the client to a physician Correct answer.
  2. Proceed with the service and use extra disinfectant afterward
  3. Buff the nail surfaces smooth and apply polish
  4. Apply an antifungal cream and continue the pedicure

Explanation

Signs of a possible fungal or other contagious nail infection are outside a nail technician's scope of practice, so the service is declined and the client is referred to a physician. Masking the condition with polish or buffing delays treatment and spreads organisms.

Question 14Infection Control, Sanitation, and Safety

Safety Data Sheets for the products used in the salon must be

  1. Kept at the owner's home office
  2. Readily accessible to every worker during the shift Correct answer.
  3. Stored in a locked drawer that only the owner can open
  4. Filed with the product supplier only

Explanation

Safety Data Sheets describe hazards, handling, and first aid for each chemical and must be available to employees while they work. Locking them away or leaving them only with the supplier denies workers access during an emergency.

Question 15Infection Control, Sanitation, and Safety

How should reusable nail drill bits be handled between clients?

  1. Clean them, then disinfect or sterilize them as the manufacturer directs Correct answer.
  2. Soak them in plain water overnight
  3. Wipe them with a dry tissue and reuse
  4. Blow compressed air over them

Explanation

Drill bits hold debris and can abrade skin, so they are cleaned and then disinfected or sterilized according to the manufacturer's instructions for that bit. Bits that cannot be cleaned and disinfected must be replaced.

Question 16Infection Control, Sanitation, and Safety

Why should a technician avoid dipping a finger into a shared jar of cream?

  1. It makes the jar harder to close
  2. It makes the cream lose its fragrance
  3. It causes the cream to change color
  4. Skin contact introduces microbes into the product, which can then spread to later clients Correct answer.

Explanation

Touching a product with skin introduces microorganisms into the container, where they can survive and be passed to every client served from that jar. Dispensing with a clean spatula or a single-use portion prevents this cross-contamination.

Question 17Infection Control, Sanitation, and Safety

A metal pusher falls onto the floor in the middle of a manicure. Before it is used again, it must be

  1. Set aside until the end of the day and then reused
  2. Wiped on the technician's uniform
  3. Rinsed under the faucet and reused
  4. Cleaned and then disinfected with an EPA-registered hospital disinfectant Correct answer.

Explanation

Floors carry soil and microorganisms, so a dropped tool is removed from service, washed with soap and water, and then fully disinfected. It cannot return to the service until both steps are complete.

Question 18Infection Control, Sanitation, and Safety

Which combination best reduces a technician's exposure to airborne nail dust?

  1. Wearing a cloth mask only while filing
  2. Local exhaust ventilation plus a dust mask Correct answer.
  3. Working faster to shorten the appointment
  4. Placing a scented candle on the station to mask odors

Explanation

Source capture with local exhaust ventilation removes fine dust at the point of generation, and an approved dust mask filters what remains. Speed, fragrance, and intermittent masks do not reduce the amount of airborne particulate inhaled.

Question 19Infection Control, Sanitation, and Safety

Which statement about an ultraviolet (UV) light cabinet is accurate?

  1. It sterilizes metal implements in a few minutes of exposure
  2. It is intended only for dry storage, not disinfection Correct answer.
  3. It removes the need to wash implements first
  4. It reliably destroys bacterial spores on metal tools

Explanation

UV cabinets do not penetrate debris or reliably reach all surfaces of an implement, so they cannot be credited with disinfection or sterilization and are treated as storage only. Cleaning and an EPA-registered disinfectant remain the required steps.

Question 20Infection Control, Sanitation, and Safety

A jar of quaternary ammonium disinfectant looks cloudy and contains visible debris. The technician should

  1. Add more concentrate to strengthen it
  2. Keep using it until the label contact time has passed
  3. Top it up with water and keep using it
  4. Discard it, clean the jar, and mix a fresh solution Correct answer.

Explanation

Cloudiness and debris show that the solution is soiled, and organic matter reduces the disinfectant's killing power. The correct response is to discard the solution, wash and dry the jar, and prepare a fresh solution at the labeled dilution.

Question 21Infection Control, Sanitation, and Safety

Which sequence correctly handles a blood spill on the manicure table?

  1. Gloves on, absorb the spill, clean the area, then disinfect it Correct answer.
  2. Rinse the area with plain water and allow it to air-dry completely
  3. Wipe the spill away with a dry paper towel and then continue the service
  4. Spray disinfectant directly onto the spill and wipe it up afterward

Explanation

Blood is handled under standard precautions: gloves first, then absorb and remove the material, clean the surface with soap and water, and finally apply an EPA-registered hospital disinfectant. Cleaning before disinfecting is essential because organic matter inactivates the chemical.

Question 22Infection Control, Sanitation, and Safety

A technician mixes a hospital disinfectant at half the labeled concentration to make it last longer. What is the result?

  1. The solution is still effective if implements soak twice as long
  2. The solution works the same but smells weaker
  3. The implements become sterile faster
  4. It may fail to kill pathogens and spread infection Correct answer.

Explanation

The label dilution is the concentration at which the product earned its kill claims; weakening it means organisms may survive the soak. Extra soaking time does not restore a diluted product to its registered strength.

Question 23Infection Control, Sanitation, and Safety

To prepare a 1:10 household bleach solution for blood-contaminated surfaces, a technician combines

  1. 1 part bleach with 9 parts water Correct answer.
  2. 1 part bleach with 1 part water
  3. 1 part bleach with 20 parts water
  4. 10 parts bleach with 1 part water

Explanation

A 1:10 dilution means one part bleach plus nine parts water, giving ten parts total solution. This ratio is the standard strength used for blood spill cleanup, and the solution is mixed fresh because bleach loses strength over time.

Question 24Infection Control, Sanitation, and Safety

While wearing gloves during a manicure, a technician answers the salon phone. What is the main risk?

  1. The phone may be damaged by product residues on the gloves
  2. The gloves lose their strength and tear more easily
  3. The client's nails may cure more slowly than usual under the lamp
  4. Pathogens pass from the gloves to the phone and then to others Correct answer.

Explanation

Gloves that have contacted a client's skin carry microorganisms, and touching shared objects such as a phone transfers them to a surface no one cleans between clients. Gloves must be removed or changed before handling anything outside the service.

Question 25Infection Control, Sanitation, and Safety

A client develops itching, redness, and swelling around the nail folds a day after an acrylic application. The most likely explanation is

  1. The natural nail plate has grown out faster than expected this month
  2. The client is developing a common cold
  3. The product was not cured long enough under the lamp
  4. Sensitization to methacrylate; remove the product and refer Correct answer.

Explanation

Itching, redness, and swelling delayed by hours to days point to allergic contact sensitization to methacrylate monomers. The product is removed, the client is referred to a physician, and the technician avoids further exposure because sensitization is lifelong.

Question 26Infection Control, Sanitation, and Safety

A nail technician should wash her hands with soap and water at which point during her workday?

  1. Only when gloves are not available
  2. Only at the beginning of the workday
  3. Before and after each client's service Correct answer.
  4. Only after handling a client's cuticle

Explanation

Hands pick up transient microorganisms from clients, tools, and surfaces, so they must be washed before and after every client service. A single washing at the start of the day leaves that contamination to be carried from one client to the next.

Question 27Infection Control, Sanitation, and Safety

A technician's glove tears in the middle of a manicure. What should she do?

  1. Rub hand sanitizer over the torn glove and continue
  2. Seal the tear with a strip of adhesive tape and continue the service
  3. Finish the service, then change gloves at the end
  4. Stop, wash hands, and put on new gloves Correct answer.

Explanation

A torn glove no longer acts as a barrier, so the technician must stop, remove the damaged glove, wash her hands, and put on a fresh pair before continuing. Contamination that reached the skin must be washed away, not simply covered.

Question 28Infection Control, Sanitation, and Safety

Which item must be thrown away after use on a single client?

  1. Reusable nipper
  2. Metal nail file
  3. Stainless steel cuticle pusher
  4. Emery board Correct answer.

Explanation

Emery boards are porous and cannot be reliably cleaned and disinfected, so they are single-use items. Nonporous metal implements can be cleaned, disinfected, and reused.

Question 29Infection Control, Sanitation, and Safety

Used razor blades and other sharp implements must be placed in

  1. A jar of disinfectant on the station
  2. A sealed envelope in a drawer
  3. A lined trash can in the service area
  4. A puncture-resistant sharps container Correct answer.

Explanation

Sharps must go directly into a closable, puncture-resistant container so that no one handling the waste can be cut and exposed to bloodborne pathogens. Improvised containers do not reliably prevent sticks.

Question 30Infection Control, Sanitation, and Safety

Before reusable metal implements go into an autoclave, they must be

  1. Rinsed in cold water and left wet
  2. Wiped with a towel and stored damp
  3. Coated with oil to prevent rust
  4. Cleaned and dried thoroughly Correct answer.

Explanation

Debris left on an implement shields microorganisms from steam and heat and can bake onto the metal, causing sterilization to fail. Implements are scrubbed, rinsed, and dried before being packaged and processed.

Question 31Infection Control, Sanitation, and Safety

A porous buffer has been used on a client's nails. Afterward it should be

  1. Wiped with alcohol and reused on the same client only
  2. Discarded in a covered waste container Correct answer.
  3. Sprayed with sanitizer and stored for the next client
  4. Soaked in disinfectant for ten minutes and reused

Explanation

Porous items absorb moisture, dust, and debris, and disinfectant cannot penetrate them to reach embedded microorganisms. Because they cannot be reliably cleaned and disinfected, they are used once and discarded.

Question 32Infection Control, Sanitation, and Safety

Bleach should never be mixed with ammonia-based products because the mixture

  1. Loses its disinfecting strength
  2. Releases a toxic gas Correct answer.
  3. Becomes flammable
  4. Stains metal implements

Explanation

Mixing bleach with ammonia produces chloramine gas, which can cause severe respiratory injury in a poorly ventilated salon. Chemicals should never be combined unless the label specifically directs it.

Question 33Infection Control, Sanitation, and Safety

A splash of disinfectant gets into a technician's eye. She should immediately

  1. Rub the eye and continue working
  2. Wait to see if irritation develops before acting
  3. Apply medicated eye drops from the salon first aid kit
  4. Flush the eye with water and get medical help Correct answer.

Explanation

Chemical splashes to the eye are flushed with clean water at an eyewash station for the time stated on the product label, then evaluated by a medical professional. Delaying or applying other products can worsen tissue damage.

Question 34Infection Control, Sanitation, and Safety

Hand sanitizer may be used in place of hand washing only when

  1. The client is not bleeding
  2. The salon has no running water that day
  3. The technician is wearing gloves
  4. The hands are not visibly soiled Correct answer.

Explanation

Alcohol-based sanitizers reduce organisms but do not remove dirt, blood, or product residue, so soap and water is required whenever hands are visibly soiled. Sanitizer is an alternative only for hands that already look clean.

Question 35Infection Control, Sanitation, and Safety

A cotton ball soaked with a client's blood should be

  1. Rinsed in the sink and thrown away
  2. Sealed in a bag and put in a covered trash can Correct answer.
  3. Left on the manicure table until the end of the day
  4. Flushed down the toilet in the restroom

Explanation

Blood-contaminated disposable items are placed in a sealable bag and deposited in a covered waste container, following the exposure control plan and local rules. Leaving them out or rinsing them spreads contamination.

Question 36Infection Control, Sanitation, and Safety

Which is the correct way to remove contaminated gloves?

  1. Peel gloves off inside out, touching only the outside Correct answer.
  2. Pull them off by the fingertips and drop them in the trash
  3. Blow into the cuff of each glove to loosen it, then slide it off
  4. Wash the gloved hands with soap and water, then pull them off

Explanation

Gloves are removed so that the contaminated outer surface ends up inside and never touches bare skin. The first glove is peeled off inside out and used to remove the second, then hands are washed.

Question 37Infection Control, Sanitation, and Safety

A technician has a small cut on her own finger. Before working on a client she should

  1. Rinse the cut with disinfectant and continue bare-handed
  2. Work only with the other hand
  3. Bandage the cut and wear gloves Correct answer.
  4. Coat the cut with polish to seal it

Explanation

Open lesions on the technician's hands must be covered with a bandage and protected by gloves so that blood contact is blocked in both directions. A dressing alone is not enough because it can slip or soak through.

Question 38Infection Control, Sanitation, and Safety

A surface has visible nail dust and debris. A technician sprays disinfectant on it without wiping it first. What is the most likely result?

  1. The disinfectant will harden the debris into a protective seal
  2. The disinfectant will work faster because the dirt absorbs it
  3. Nothing changes, because disinfectants work in the presence of soil
  4. The soil weakens the disinfectant, so germs may survive Correct answer.

Explanation

Organic material such as dust, skin, and product residue reacts with the disinfectant and reduces its killing power on the surface beneath. Surfaces must be cleaned of visible debris first, then treated with disinfectant.

Question 39Infection Control, Sanitation, and Safety

A metal implement is still wet when it is sealed inside an autoclave pouch and processed. What is the main problem?

  1. The pouch will melt onto the implement
  2. The autoclave will shut off automatically before the cycle ends
  3. The implement will become permanently dull
  4. Trapped moisture can prevent the item from being sterilized Correct answer.

Explanation

Moisture inside a sealed pouch can block steam contact and keep the item from reaching sterilization conditions, and it also compromises the package's ability to keep the item sterile. Implements are dried before packaging.

Question 40Infection Control, Sanitation, and Safety

Standard precautions require the technician to treat

  1. Only body fluids from clients with visible skin lesions as infectious
  2. Only blood and body fluids that are visibly contaminated as infectious
  3. Only blood from clients who admit to having a disease as infectious
  4. All blood and body fluids as potentially infectious Correct answer.

Explanation

Standard precautions assume that every client's blood and body fluids may carry pathogens, because infections are often invisible and clients may not know their status. Gloves, hand hygiene, and disinfection are therefore applied to all services.

Question 41Manicuring and Pedicuring

The nail plate is made up mainly of which protein?

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

Explanation

The nail plate is formed from tightly packed, hardened keratin cells produced by the matrix. Collagen, elastin, and melanin are structural or pigment proteins found elsewhere in the body and are not the building block of the plate.

Question 42Manicuring and Pedicuring

How should a natural nail be filed to protect the free edge?

  1. From the center toward each corner in one direction
  2. Back and forth quickly across the free edge
  3. From the corner toward the center in one direction Correct answer.
  4. In small circles around the free edge

Explanation

Filing from the side of the free edge toward the center in a single direction keeps the layers of the plate from separating. Sawing back and forth creates friction that splits and frays the free edge.

Question 43Manicuring and Pedicuring

What is the main purpose of applying a base coat before nail polish?

  1. It fills ridges so the color lies flat
  2. It removes oils so the color sets faster
  3. It builds strength and thickness into the plate
  4. It helps the polish adhere and prevents staining Correct answer.

Explanation

Base coat creates a bonding layer between the plate and the color while shielding the plate from pigment stains. Ridge fillers and nail strengtheners are separate products with their own purposes.

Question 44Manicuring and Pedicuring

A cuticle pusher is used to perform which action?

  1. Trimming dead tissue at the nail base
  2. Filing the free edge into shape
  3. Smoothing ridges on the nail plate
  4. Pushing cuticle back from the plate Correct answer.

Explanation

A cuticle pusher is a blunt tool used to gently ease the cuticle and eponychium back off the nail plate. Trimming dead tissue requires nippers, and shaping or smoothing requires files or buffers.

Question 45Manicuring and Pedicuring

Which description matches a square nail shape?

  1. Straight sides with rounded corners
  2. Straight sides with a flat free edge Correct answer.
  3. Sides that taper to a rounded point
  4. Sides that taper to a sharp point

Explanation

A square nail has parallel sidewalls and a free edge filed straight across at a 90-degree angle. Adding rounded corners makes it a squoval, and tapering produces oval or pointed shapes.

Question 46Manicuring and Pedicuring

What is the purpose of soaking the feet at the start of a pedicure?

  1. It removes hard callus from the heel
  2. It softens tissue and cleanses the skin Correct answer.
  3. It disinfects the skin before service
  4. It closes the pores to prevent infection

Explanation

A warm soak softens the cuticle, skin, and nails and loosens surface debris so later steps are gentler. Soaking does not disinfect the skin, and hard callus still requires abrasion and product.

Question 47Manicuring and Pedicuring

What does a top coat do for a finished manicure?

  1. It seals the color and adds a glossy shine Correct answer.
  2. It fills ridges so the color lies flat
  3. It removes oils so the color adheres
  4. It builds strength and thickness into the nail

Explanation

Top coat is applied last to seal the color coats and give the surface its shine and protection. Ridge filling, strengthening, and oil removal are handled by other products at earlier steps.

Question 48Manicuring and Pedicuring

Exfoliation during a pedicure removes which material?

  1. Hair follicles from the toes
  2. Dead cells from the skin's surface Correct answer.
  3. Surface layers of the nail plate
  4. Natural pigment from the skin

Explanation

Exfoliants lift and slough away dead keratinized cells sitting on the surface of the skin. They do not affect pigment, hair follicles, or the nail plate itself.

Question 49Manicuring and Pedicuring

At what average rate do fingernails grow?

  1. About 1/2 inch per month
  2. About 1/16 inch per year
  3. About 1/8 inch per month Correct answer.
  4. About 1 inch per month

Explanation

Fingernails typically grow about one-eighth of an inch per month, or roughly 0.1 mm per day. Growth is slower in toenails and varies with age, season, and health.

Question 50Manicuring and Pedicuring

When is it appropriate to use cuticle nippers during a manicure?

  1. To cut the eponychium around every nail
  2. Only on hangnails and clearly dead tissue Correct answer.
  3. To trim the free edge after filing
  4. To remove callus from the toes

Explanation

Nippers are reserved for a hanging tag of skin or a bit of clearly nonliving tissue, because cutting living tissue can cause bleeding and infection. Routine removal of the eponychium is not part of a standard manicure.
