Question 1Infection Control, Sanitation and Safety

What should a nail technician do before beginning a manicure on a new client?

  1. Apply lotion to the client's hands to soften the cuticles
  2. Put on gloves over hands that are still soiled
  3. Wash hands with soap and water and dry with a clean towel Correct answer.
  4. Wipe the work surface once with a dry cloth

Explanation

Hand hygiene is the first step before any service; hands are washed with soap and water or treated with an alcohol-based hand rub and dried with a clean disposable towel. Gloves are not a substitute for washing, and a dry cloth does not clean or disinfect a surface.

Question 2Infection Control, Sanitation and Safety

Disinfection is best described as a process that

  1. Kills most pathogenic microorganisms on nonporous surfaces Correct answer.
  2. Destroys all microbial life, including bacterial spores
  3. Removes visible debris but does not affect microorganisms
  4. Sterilizes porous items so they can be reused

Explanation

Disinfection reduces or kills most pathogenic microorganisms on inanimate nonporous surfaces but does not destroy bacterial spores; that is sterilization. Cleaning removes visible debris, and porous items cannot be reliably disinfected for reuse.

Question 3Infection Control, Sanitation and Safety

Which item is intended for single use and must be discarded after one client?

  1. Foam-core nail file Correct answer.
  2. Autoclave tray
  3. Glass mixing dish
  4. Metal cuticle pusher

Explanation

Foam-core files are porous, absorb fluids, and cannot be reliably cleaned and disinfected, so they are discarded after one client. Metal pushers, glass dishes, and autoclave trays are nonporous and can be cleaned and then disinfected or sterilized.

Question 4Infection Control, Sanitation and Safety

During a service, when should a nail technician change gloves?

  1. At the end of the day only
  2. Only after they become visibly soiled with product
  3. When moving from a soiled task to a clean task Correct answer.
  4. After every 30 minutes of continuous work on one client

Explanation

Gloves must be changed when they are torn or visibly soiled and whenever the technician moves from a contaminated task to a clean one to prevent cross-contamination. Gloves are never washed and reused, and a time schedule alone does not replace task-based changes.

Question 5Infection Control, Sanitation and Safety

What is the main purpose of a Safety Data Sheet (SDS)?

  1. To explain hazards, safe handling, and first aid Correct answer.
  2. To certify that a product is approved by the FDA
  3. To replace the product label during storage
  4. To list the retail price and shelf life of a product

Explanation

An SDS summarizes a product's hazards, safe handling, and first-aid measures and must be available to workers for hazardous chemicals. It does not certify approval, set prices, or take the place of the container label.

Question 6Infection Control, Sanitation and Safety

How should acrylic monomer and other salon chemicals be stored?

  1. In an unmarked beverage bottle in a refrigerator
  2. In an open tray near the client's hands
  3. In a closed, labeled container away from heat Correct answer.
  4. In direct sunlight beside the workstation

Explanation

Chemicals should be kept in closed, properly labeled containers away from heat, sparks, and flames because many nail products are flammable and volatile. Unmarked beverage containers invite accidental ingestion, sunlight can degrade products, and open trays increase inhalation exposure.

Question 7Infection Control, Sanitation and Safety

If a client's skin is nicked and blood appears during a service, what should the technician do?

  1. Rinse the implement in water and keep using it
  2. Stop, put on fresh gloves, and clean the area Correct answer.
  3. Continue the service and wipe the blood with a towel
  4. Blow on the area until the blood dries

Explanation

Blood exposure requires stopping the service, putting on fresh gloves, cleaning the wound, and disposing of contaminated materials properly. Implements and surfaces that contacted blood must be cleaned and disinfected, and the incident should be documented according to the exposure control plan.

Question 8Infection Control, Sanitation and Safety

How should disposable sharp items, such as used razor blades, be discarded?

  1. Wrapped loosely in a paper towel and placed in the regular trash
  2. Placed loose in a drawer until the end of the day
  3. Recycled with glass bottles and cans
  4. Placed in a rigid, puncture-resistant sharps container Correct answer.

Explanation

Disposable sharps must go into a rigid, puncture-resistant, closable sharps container to prevent needlesticks and cuts. Paper towels, loose drawers, and recycling bins do not protect workers from injury.

Question 9Infection Control, Sanitation and Safety

A disinfectant label reads 'EPA-registered hospital disinfectant, 10-minute contact time.' What does this require?

  1. Reuse the same solution for 10 clients
  2. Leave the product on for 10 seconds only
  3. Keep the surface wet with product for 10 minutes Correct answer.
  4. Wipe the product off immediately after spraying

Explanation

Contact time is the period the surface must remain visibly wet with the disinfectant for the label's claims to be valid. Wiping immediately or shortening the time can leave pathogens alive; disinfectants are not sterilants, and solutions are not reused beyond label directions.

Question 10Infection Control, Sanitation and Safety

Which item is porous and therefore cannot be reliably disinfected for reuse?

  1. Terry cloth towel Correct answer.
  2. Glass mixing dish
  3. Glazed ceramic pedicure bowl
  4. Stainless steel nippers

Explanation

Porous materials absorb liquids and trap microorganisms, so they cannot be reliably disinfected and should be single-use or laundered. Nonporous items such as metal, glass, and glazed ceramic can be cleaned and disinfected.

Question 11Infection Control, Sanitation and Safety

After each client, how should a whirlpool foot spa be processed?

  1. Fill it with hot water and run the jets for one minute only
  2. Drain, clean, and disinfect for the labeled contact time Correct answer.
  3. Rinse with water only and leave it to air dry
  4. Wipe with a dry paper towel

Explanation

Foot spas must be drained, cleaned of debris, and disinfected with an EPA-registered product for the full labeled contact time after each client. Rinsing or wiping alone leaves biofilm and pathogens in the jets and tubing.

Question 12Infection Control, Sanitation and Safety

Which process achieves sterilization of metal implements?

  1. Soaking in quaternary ammonium disinfectant for 10 minutes
  2. Wiping with 70% alcohol
  3. Submerging in bleach solution for 5 minutes
  4. Cleaning, then processing in an autoclave Correct answer.

Explanation

Sterilization destroys all microbial life, including spores, and is achieved with an autoclave, dry heat, or chemical sterilant after cleaning. Disinfectants such as quats, alcohol, and bleach at disinfection strength do not sterilize.

Question 13Infection Control, Sanitation and Safety

What is the likely result if a quaternary ammonium disinfectant is mixed with too much water?

  1. It will become safe to drink
  2. It will no longer require any contact time
  3. It may fail to kill pathogens within the contact time Correct answer.
  4. It will sterilize implements instead of disinfecting

Explanation

Disinfectants must be diluted exactly as labeled; too much water lowers the active ingredient concentration so it may not kill pathogens within the contact time. Overdilution does not create a sterilant or eliminate the need for contact time.

Question 14Infection Control, Sanitation and Safety

Which infection is spread mainly through blood and can be prevented by vaccination?

  1. Hepatitis B Correct answer.
  2. Pediculosis
  3. Mycobacterium fortuitum
  4. Tinea pedis

Explanation

Hepatitis B is a bloodborne virus, and vaccination is the primary prevention for at-risk workers. Tinea pedis and pediculosis are not bloodborne, and Mycobacterium fortuitum is associated with contaminated water.

Question 15Infection Control, Sanitation and Safety

How should reusable nail drill bits be processed between clients?

  1. Soak in plain water overnight only
  2. Clean debris, then disinfect or sterilize as directed Correct answer.
  3. Brush off visible debris and place them in a drawer
  4. Spray them with air freshener and reuse them on the next client

Explanation

Reusable drill bits must be cleaned of debris and then disinfected or sterilized according to the manufacturer's instructions because debris shields microorganisms. Water alone and air freshener do not disinfect, and dirty storage recontaminates the bit.

Question 16Infection Control, Sanitation and Safety

Which is a reasonable safety practice when using a UV/LED nail lamp?

  1. Have clients press bare skin against the bulb
  2. Follow manufacturer instructions and protect sensitive skin Correct answer.
  3. Use a lamp with a cracked or frayed cord
  4. Clean the lamp with acetone while it remains plugged into the outlet

Explanation

Lamp use should follow manufacturer instructions, including cleaning and electrical safety, and clients with sensitive skin may be offered protection. Cracked cords, acetone near energized equipment, and direct skin contact with bulbs are hazards.

Question 17Infection Control, Sanitation and Safety

Why is local exhaust ventilation important at a nail workstation?

  1. It removes vapors and dust from the breathing zone Correct answer.
  2. It sterilizes metal implements between client services
  3. It cools the UV lamp for faster curing
  4. It replaces the need for gloves

Explanation

Local exhaust ventilation captures vapors and dust at the source before they reach the technician's breathing zone. It does not sterilize tools, cool lamps, or replace gloves.

Question 18Infection Control, Sanitation and Safety

A client arrives with red, swollen, oozing skin around a toenail. What should the technician do?

  1. Proceed with the service but use extra disinfectant
  2. Trim the swollen tissue with sterile nippers
  3. Apply acrylic over the area to seal it from air
  4. Postpone the service and refer to a physician Correct answer.

Explanation

Red, swollen, oozing skin suggests infection or inflammation, which is a contraindication for nail services. The technician should not treat it, cover it with product, or cut tissue and should refer the client to a physician.

Question 19Infection Control, Sanitation and Safety

How should soiled salon towels and linens be handled?

  1. Held in a closed container, then laundered properly Correct answer.
  2. Rinsed in the pedicure tub and hung to dry
  3. Stored in the same bin as clean towels
  4. Shaken out in the service area and reused for the next client

Explanation

Soiled linens should be kept separate from clean linens and laundered with detergent and hot water or bleach according to instructions to reduce contamination. Shaking them spreads microorganisms, and rinsing in a pedicure tub contaminates the equipment.

Question 20Infection Control, Sanitation and Safety

A technician develops itchy, cracked skin and a rash after working with acrylic liquid. This is most likely

  1. A bacterial skin infection caught from a client
  2. A sign of hepatitis B infection
  3. A fungal infection from a towel
  4. Allergic dermatitis from the monomer Correct answer.

Explanation

Acrylic monomers can cause allergic contact dermatitis, often presenting as itching, redness, and cracked skin; the technician should stop exposure and seek medical advice. It is not a bacterial or fungal infection and is not a sign of hepatitis B.

Question 21Infection Control, Sanitation and Safety

Why should a technician test a reusable disinfectant with strips or a test kit?

  1. To check whether the solution has sterilized tools
  2. To measure the hardness of the tap water
  3. To determine the pH of the client's skin
  4. To confirm the active ingredient is still effective Correct answer.

Explanation

Reusable disinfectants can lose strength from dilution, evaporation, or repeated use, so test strips or kits verify the active ingredient concentration. They do not measure water hardness, confirm sterilization, or test skin pH.

Question 22Infection Control, Sanitation and Safety

Why is biofilm difficult to remove from a pedicure whirlpool?

  1. It is destroyed as soon as the tub is drained
  2. It forms only on the metal parts inside the tub
  3. Microbes sit in a slime layer that shields them Correct answer.
  4. It is a mineral deposit that soap removes easily

Explanation

Biofilm is a slimy layer of microorganisms that adheres to surfaces and protects them from disinfectants, so tubs must be scrubbed and treated for the full contact time. Draining alone does not remove it, and it is not a mineral deposit.

Question 23Infection Control, Sanitation and Safety

Mycobacterium fortuitum infections in nail salon clients have been linked mainly to

  1. Contaminated foot spa water and poor cleaning Correct answer.
  2. Using a metal nail file on natural nails
  3. Sharing nail polish bottles between clients
  4. Inhaling acrylic monomer vapors

Explanation

Mycobacterium fortuitum is an environmental organism linked to whirlpool foot spas when water and tubing are not adequately cleaned and disinfected. It is not transmitted by polish bottles, vapors, or files.

Question 24Infection Control, Sanitation and Safety

What is the purpose of an exposure control plan in a salon?

  1. To document client appointments, payments, and service history
  2. To outline steps that reduce exposure to bloodborne pathogens Correct answer.
  3. To list the prices of all salon services
  4. To describe how to clean the reception area each morning

Explanation

An exposure control plan is a written program required to reduce occupational exposure to bloodborne pathogens and to manage exposure incidents. It does not cover pricing, appointments, or routine reception cleaning.

Question 25Infection Control, Sanitation and Safety

Why should a technician avoid mixing bleach with other cleaning products?

  1. Toxic gases may form and effectiveness may drop Correct answer.
  2. Mixing makes bleach safer for the skin
  3. Mixing removes the need for contact time
  4. Mixing turns the bleach into a chemical sterilant

Explanation

Bleach can react with ammonia or acids in other products to release toxic gases, and mixing can also change the concentration so disinfection fails. It does not create a sterilant, remove contact time, or make bleach safe for skin.

Question 26Infection Control, Sanitation and Safety

Before a metal implement is placed in disinfectant, why must it first be cleaned?

  1. To give the metal a protective coating
  2. To make the disinfectant work faster
  3. To remove debris that shields microbes Correct answer.
  4. To prevent the implement from rusting

Explanation

Cleaning removes blood, oil, and other organic debris from the surface. Disinfectants cannot penetrate organic matter well, so microbes underneath can survive. Cleaning must always come before disinfection.

Question 27Infection Control, Sanitation and Safety

How long should a nail technician lather the hands during routine hand washing?

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

Explanation

Routine hand washing should involve soap, friction, and water for about 20 seconds, covering the palms, backs, fingers, and under the nails. Shorter washing may not remove transient microorganisms effectively. Longer scrubbing is not required for routine salon hand hygiene.

Question 28Infection Control, Sanitation and Safety

A technician will perform a manicure on a client with intact skin. Which personal protective equipment is standard?

  1. A lead apron
  2. Clean gloves Correct answer.
  3. Steel-toed shoes
  4. A face shield

Explanation

Clean disposable gloves are standard for services that involve contact with skin, nails, and potential body fluids. They protect both the client and the technician. Other listed items are not routine PPE for a manicure.

Question 29Infection Control, Sanitation and Safety

What is the main purpose of a Safety Data Sheet for a salon product?

  1. To certify that the product is sterile
  2. To list the retail price of the product
  3. To describe hazards and safe handling Correct answer.
  4. To record the client's appointment times

Explanation

A Safety Data Sheet provides information about a product's hazards, safe handling, storage, and first-aid measures. It helps technicians use chemicals safely and respond to spills or exposures. It is not a pricing, sterility, or appointment document.

Question 30Infection Control, Sanitation and Safety

Which item is intended for single use and should be discarded after one client?

  1. A glass mixing dish
  2. A stainless steel pusher
  3. A wooden emery board Correct answer.
  4. Metal cuticle nippers

Explanation

Porous items such as wooden emery boards cannot be reliably cleaned and disinfected for reuse. They should be discarded after a single client. Metal and glass items can be processed for reuse when handled correctly.

Question 31Infection Control, Sanitation and Safety

What does an EPA registration number on a salon disinfectant indicate?

  1. Its labeled claims were reviewed Correct answer.
  2. It needs no dilution
  3. The product is sterile
  4. It is safe for all skin types

Explanation

EPA registration means the product's labeled claims and use directions have been reviewed for the stated uses. It does not mean the product is sterile, harmless to all skin, or ready to use without dilution. Technicians must still follow the label.

Question 32Infection Control, Sanitation and Safety

Why should food and drinks be kept out of the nail service area?

  1. They make the salon look untidy
  2. They attract more clients
  3. They can pick up dust and mist Correct answer.
  4. They slow down the appointment

Explanation

Food and drinks can become contaminated with nail dust, chemical mist, and microorganisms in the service area. Keeping them out protects both clients and staff from accidental ingestion. Appearance and speed are not the health reason.

Question 33Infection Control, Sanitation and Safety

When should a nail technician wash their hands in relation to disposable gloves?

  1. Only if the gloves look dirty
  2. Only after removing the gloves
  3. Both before and after glove use Correct answer.
  4. Only before putting on the gloves

Explanation

Hands should be washed before donning gloves and again after removing them. Washing before protects the client, and washing after protects the technician from contamination that may occur during removal. Gloves are not a substitute for hand hygiene.

Question 34Infection Control, Sanitation and Safety

How does disinfecting differ from sanitizing?

  1. Sanitizing is only for metal tools
  2. The two processes are identical
  3. Sanitizing kills more pathogens
  4. Disinfecting kills more pathogens Correct answer.

Explanation

Sanitizing reduces the number of microorganisms, while disinfecting destroys or inactivates most disease-causing organisms on surfaces. Disinfecting is therefore a higher level of microbial control than sanitizing. The terms are not interchangeable.

Question 35Infection Control, Sanitation and Safety

After each client, how should the manicure table surface be treated?

  1. Sprayed with water only
  2. Covered with a fresh towel
  3. Cleaned then disinfected Correct answer.
  4. Wiped with a dry cloth

Explanation

Surfaces must first be cleaned to remove soil, then treated with an EPA-registered disinfectant according to its label. The surface should be allowed to remain wet for the labeled contact time. A dry wipe or water alone does not disinfect.

Question 36Infection Control, Sanitation and Safety

A technician's glove tears midway through a service. What is the best action?

  1. Continue and change gloves at the end
  2. Wipe the glove and continue
  3. Tape the tear and keep working
  4. Stop, wash, and don new gloves Correct answer.

Explanation

A torn glove no longer provides a barrier, so the technician should stop, remove the glove, wash hands, and put on a new glove before continuing. Taping or wiping a torn glove does not restore protection. This prevents contact with blood or body fluids.

Question 37Infection Control, Sanitation and Safety

A metal pusher is contaminated with a client's blood. How should it be processed before reuse?

  1. Cleaned then tuberculocidal-disinfected Correct answer.
  2. Wiped with alcohol and used on the next client
  3. Rinsed in water and returned to the drawer
  4. Soaked in soapy water and dried

Explanation

Blood-contaminated reusable implements must be cleaned and then disinfected with an EPA-registered hospital disinfectant carrying a tuberculocidal claim, or sterilized. This level of disinfection is required for bloodborne pathogen exposure. Rinsing or alcohol wiping alone is not adequate.

Question 38Infection Control, Sanitation and Safety

A disposable towel is saturated with blood. How should it be discarded?

  1. In a labeled biohazard bag Correct answer.
  2. Flushed down the sink
  3. In the open trash can
  4. In the clean towel cabinet

Explanation

Items soaked with blood should be placed in a sealed, labeled biohazard bag and disposed of according to local regulations. This prevents exposure to others who handle the waste. Open trash, sinks, and clean storage areas are not appropriate.

Question 39Infection Control, Sanitation and Safety

Why should electrical equipment be kept away from pedicure bowls filled with water?

  1. Water improves the equipment's look
  2. Water voids the equipment's warranty
  3. Water raises shock risk Correct answer.
  4. Water makes equipment run faster

Explanation

Water conducts electricity, so electrical equipment near filled bowls increases the risk of electric shock. Equipment should be placed and used according to the manufacturer's safety instructions. Keeping cords and devices away from water is a basic electrical safety rule.

Question 40Infection Control, Sanitation and Safety

Why should a technician wear a dust mask when filing acrylic nails?

  1. To reduce inhalation of nail dust Correct answer.
  2. To improve the shine of the acrylic
  3. To keep the client's nails from drying
  4. To stop the file from slipping

Explanation

Filing acrylic creates fine dust that can be inhaled and irritate the respiratory tract. A dust mask, along with ventilation, helps reduce exposure. Masks do not affect nail drying, shine, or file grip.

Question 41Infection Control, Sanitation and Safety

A client's health history notes an untreated contagious skin infection on the hands. What should the technician do?

  1. Proceed but shorten the service
  2. Perform the service with extra gloves
  3. Decline and refer to a physician Correct answer.
  4. Apply disinfectant to the client's hands

Explanation

A contagious skin infection can spread through contact and may be worsened by nail services. The technician should decline the service and refer the client for medical evaluation. Extra gloves or disinfectant do not make the service safe.

Question 42Infection Control, Sanitation and Safety

Which label claim indicates a disinfectant is suitable for items contaminated with blood?

  1. Rust inhibiting
  2. Fungicidal
  3. Deodorizing
  4. Tuberculocidal Correct answer.

Explanation

A tuberculocidal claim shows the disinfectant can kill mycobacteria, which are relatively resistant and used as a benchmark for bloodborne pathogen efficacy. Salon disinfectants for blood-contaminated items should carry this claim. Fungicidal, deodorizing, and rust-inhibiting claims do not establish that level of efficacy.

Question 43Infection Control, Sanitation and Safety

How should disinfected metal implements be stored until use?

  1. In a drawer with soiled files
  2. In a cloth bag on the counter
  3. In a clean, covered container Correct answer.
  4. In a bowl of standing water

Explanation

Disinfected implements should be stored in a clean, dry, covered container to prevent recontamination before use. They should be kept separate from soiled items. Standing water can support microbial growth.

Question 44Infection Control, Sanitation and Safety

How should clean towels be stored in the salon?

  1. Under the pedicure bowl
  2. In a closed cabinet Correct answer.
  3. In the same bin as used towels
  4. On the floor near the sink

Explanation

Clean linens must be kept separate from soiled linens and protected from dust, moisture, and contamination. A closed cabinet provides appropriate storage. Mixing clean and used towels defeats the purpose of laundering.

Question 45Infection Control, Sanitation and Safety

What is the purpose of running a spore test on a sterilizer?

  1. To check the sterilizer is working Correct answer.
  2. To shorten the sterilization cycle
  3. To make instruments look shiny
  4. To scent the sterilization chamber

Explanation

Spore tests use highly resistant bacterial spores to verify that the sterilizer is actually achieving sterilization. If spores survive, the sterilizer needs servicing. Shine, cycle length, and scent are not the purpose.

Question 46Infection Control, Sanitation and Safety

Why can a porous item such as a wooden stick not be reliably disinfected for reuse?

  1. Wood is too soft to handle safely
  2. Wood changes color in disinfectant
  3. Disinfectant cannot reach into pores Correct answer.
  4. Wood absorbs too much water and swells

Explanation

Porous materials have tiny openings that disinfectant may not penetrate, allowing microorganisms to remain protected inside. Such items cannot be reliably disinfected and should be used once and discarded. Absorption, color change, and softness are not the main infection-control reason.

Question 47Infection Control, Sanitation and Safety

A technician mixes a disinfectant correctly but soaks implements for only half the labeled contact time. What is the most likely result?

  1. The implements will rust faster
  2. The disinfectant becomes stronger
  3. Some pathogens may survive Correct answer.
  4. The implements become sterile anyway

Explanation

Contact time is the period the item must remain wet with the disinfectant for the labeled kill claims to be met. Shortening that time can leave surviving pathogens on the implement. Correct dilution does not make up for insufficient contact time.

Question 48Infection Control, Sanitation and Safety

Which action best prevents cross-contamination between two clients?

  1. Reusing the same nail file after brushing off the dust
  2. Discarding single-use items and disinfecting tools Correct answer.
  3. Using one pair of gloves for two clients
  4. Wiping the metal nippers on a towel between clients

Explanation

Cross-contamination is prevented by using single-use items once and properly cleaning and disinfecting reusable implements between clients. Brushing or wiping does not remove or kill pathogens. Gloves must also be changed between clients.

Question 49Infection Control, Sanitation and Safety

A technician has a small cut on their hand before starting a service. What should they do?

  1. Ask the client to hold the file
  2. Apply lotion and continue the service
  3. Bandage it and wear gloves Correct answer.
  4. Work without gloves to keep the cut dry

Explanation

A cut on the technician's hand must be covered with a waterproof bandage and protected with gloves during service. This protects the technician from bloodborne pathogens and protects the client from the technician's blood. Working without gloves or with lotion does not provide a barrier.

Question 50Infection Control, Sanitation and Safety

Why should disinfected implements be completely dry before being stored?

  1. Dry implements are easier to sell
  2. Moisture makes metal stronger
  3. Moisture supports microbial growth Correct answer.
  4. Wet implements disinfect faster

Explanation

Residual moisture creates conditions where bacteria and fungi can multiply, potentially recontaminating disinfected implements. Drying before storage helps maintain the disinfected state. Sales appeal and metal strength are not the infection-control reasons.
