Nail Technician 26 Exam Questions & Answers 2026 (11–20)

Question 1

Methyl methacrylate (MMA) monomer is banned for use in nail salons by most U.S. state boards primarily because:

TheoryPractice · Accepted Answer

It causes severe skin sensitization, allergic reactions, and irreversible damage to the nail plate, and was prohibited by the FDA for use in nail products. The FDA took action against MMA because it causes serious adverse effects including irreversible nail damage and severe allergic sensitization; most state boards subsequently banned it from professional nail services, reflecting the NIC and Milady standard curriculum warning.

Question 2

Proper salon ventilation is required primarily to protect nail technicians from which occupational hazard?

TheoryPractice · Accepted Answer

Cumulative overexposure to chemical vapors and dust from nail products, which can cause respiratory sensitization and systemic harm. The overexposure principle in nail-tech curriculum and OSHA guidelines identifies chronic inhalation of monomer vapors, acrylic dust, and solvent fumes as a leading occupational hazard; local exhaust ventilation (LEV) at the table is the primary engineering control.

Question 3

Which of the following implements CAN be properly disinfected and reused on a new client after following the correct disinfection protocol?

TheoryPractice · Accepted Answer

Stainless steel cuticle nipper. Non-porous metal implements such as stainless steel nippers can be thoroughly cleaned, fully immersed in or exposed to EPA-registered disinfectant for the required contact time, and reused; porous items like emery boards, wooden sticks, and pumice stones cannot be effectively disinfected and must be discarded after one use.

Question 4

Which part of the nail is responsible for producing the nail plate?

TheoryPractice · Accepted Answer

Matrix. The matrix contains the germinal cells that actively divide and produce the nail plate; damage to the matrix can result in permanent nail deformity.

Question 5

The visible white half-moon shape at the base of the nail plate is called the:

TheoryPractice · Accepted Answer

Lunula. The lunula is the visible portion of the matrix that appears as a white, half-moon shape at the base of the nail plate, most visible on the thumb.

Question 6

The thin layer of living skin that overlaps the base of the nail plate and is attached to the nail plate surface is called the:

TheoryPractice · Accepted Answer

Eponychium. The eponychium is the living skin that overlaps the nail plate at the base; it should never be cut, as doing so creates an opening for infection.

Question 7

A client presents with nails that are thick, yellow-brown, and crumbling. This presentation is most consistent with which condition that a nail technician MUST refuse to service?

TheoryPractice · Accepted Answer

Onychomycosis. Onychomycosis is a fungal infection of the nail producing thick, discolored, brittle nails and is an infectious disease requiring referral to a physician, not a service a nail technician may perform.

Question 8

After finishing a service, implements that penetrate the skin or contact blood must be:

TheoryPractice · Accepted Answer

Discarded as single-use sharps after each client. Per OSHA bloodborne pathogen standards and NIC infection-control guidelines, any implement that breaks the skin or contacts blood is a single-use item and must be discarded after each client.

Question 9

An EPA-registered, hospital-grade disinfectant is used at the correct dilution and left on a surface for the full contact time specified on the label. This process achieves:

TheoryPractice · Accepted Answer

Disinfection — destroying most pathogens on non-porous surfaces. Disinfection destroys most pathogens on non-porous surfaces but does not kill all bacterial spores; sterilization (which does destroy spores) is not required or achievable with standard salon disinfectants.

Question 10

A client has redness, swelling, and pus around the lateral nail fold of one finger. This condition is known as paronychia and the correct course of action is to:

TheoryPractice · Accepted Answer

Decline the service and refer the client to a physician. Paronychia is a bacterial or fungal infection of the skin surrounding the nail; performing any service on an infected area violates infection-control standards and the client must be referred to a licensed healthcare provider.
