Nail Technology Practice Questions (2026) — Free Sample Questions with Answers

Answer: D

Opening a window across the room: A distant window does little at the work area and does not reduce the vapor being released.

Wearing a paper dust mask: A dust mask filters particles, not vapors, and does not reduce what is released.

Running a ceiling fan overhead: A ceiling fan stirs vapor around the room rather than reducing it.

Using a covered dappen dish: Correct: keeping monomer in a small covered dish (and bottles capped) limits evaporation at its source.

Reduce vapors at the source: small covered dappen dishes, capped bottles and source-capture ventilation; masks and fans do not solve vapor exposure.

Answer: D

Put on gloves: Gloving is the next step (if not already gloved), after stopping the service.

Apply an antiseptic: Antiseptic is applied after the technician stops, gloves and cleans the injured area.

Apply a bandage: Bandaging comes later, after the area is cleaned and antiseptic is applied.

Stop the service: Correct: the blood exposure procedure begins by stopping the service; gloving, cleaning the wound, antiseptic and bandage follow.

Blood exposure order: stop service, glove, clean the injury, apply antiseptic, bandage, bag contaminated items, clean and disinfect the station and implements, wash hands, document.

Answer: A

Stop and refer to a physician: Correct: these are signs of an infection of the skin around the nail (paronychia). A nail tech does not service infected tissue and refers the client to a physician.

Apply antiseptic and continue: An antiseptic does not make it safe to service infected tissue; the infection can spread.

Soak the finger longer: Soaking does not treat infection, and working on the area continues an unsafe service.

Nip back the swollen skin: Cutting inflamed, infected tissue is unsafe and could spread the infection.

Redness, swelling and pus around the nail mean infection (paronychia). Do not service the area; refer to a physician.

Answer: B

Gastrocnemius: The gastrocnemius is the calf muscle at the back of the leg; it pulls the foot downward.

Tibialis anterior: Correct: the tibialis anterior covers the front of the shin and bends the foot upward and inward.

Soleus: The soleus lies under the gastrocnemius at the back of the leg and also points the foot down.

Peroneus longus: The peroneus longus runs along the outer leg and turns the foot outward and down.

Front of the shin: tibialis anterior lifts the foot. Back of the calf: gastrocnemius and soleus point it down.

Answer: D

Too much dehydrator on the nail: Dehydrator evaporates before gel is applied and plays no part in the curing heat.

An aging lamp due for replacement: An aging lamp puts out less light, which tends to undercure gel rather than make it hot.

Sticky inhibition layer on the surface: The inhibition layer is a thin uncured film; it does not generate the heat.

Heat released by the curing reaction: Correct: gel polymerization is exothermic; a heavy layer or a fast cure releases heat quickly (a heat spike).

Curing is exothermic. Thin layers and brief removal from the lamp manage heat spikes.

Answer: D

Swollen, red nail fold with pus: Pus and swelling signal infection (paronychia); service on the area is declined and the client referred.

Thick, yellow, crumbling nail: These are signs of a possible fungal infection; the nail is not serviced and the client is referred.

Open cut along the sidewall: An open wound is a contraindication; work stops on that area to avoid infection and blood exposure.

Shallow vertical ridges: Correct: longitudinal ridges are a common, noninfectious condition; the nail can be serviced, buffing gently.

Infection, inflammation and open wounds are contraindications; harmless conditions such as vertical ridges can be serviced with care.

Answer: B

Cuticle nipper: Nippers are made for loose dead tissue; cutting thick nail dulls them and can split the nail.

Toenail clipper: Correct: a large, straight-edged toenail clipper is built to cut thick toenails straight across.

Fingernail clipper: A small fingernail clipper is too weak for thick toenails and can crack them.

Coarse foot file: A foot file reduces calluses on skin; it is not used to shorten toenails.

Use toenail clippers for toenails (cut straight across), nippers only for loose dead tissue.

Answer: A

Tilting the bit's edge: Correct: the bit must stay flat (parallel) to the surface; angling its edge into the product cuts grooves ("rings of fire").

Running the file in reverse rotation: Reverse rotation is a normal setting for working the opposite sidewall; direction alone does not gouge.

Working with light pressure: Light pressure prevents gouging; it does not cause grooves.

Using a fine-grit bit: A finer grit removes less product and leaves a smoother surface, not deep grooves.

Keep the e-file bit flat to the nail, moving constantly with light pressure; an angled bit edge cuts grooves.

Answer: B

Use light friction over the veins: Any rubbing directly over varicose veins can damage the weakened vessels; the area is avoided.

Avoid massaging over the veins: Correct: pressure over varicose veins can injure the weakened vessels, so the area is skipped and the rest of the service continues gently.

Use only effleurage on the veins: Even gentle stroking is kept off varicose veins; massage avoids them completely.

Use warm stones over the veins: Heat and pressure over varicose veins are contraindicated.

Varicose veins are a local contraindication: do not massage over them, and refer the client to a physician if unsure.

Answer: D

Top coat applied too thinly: A thin top coat gives less shine and wear protection; it does not make the whole film release from the plate.

Free edge left uncapped: Skipping the free-edge cap causes chipping at the tips, not peeling of the whole film.

Polish bottle shaken hard: Shaking adds air bubbles to the film; it does not cause the film to release from the plate.

Oil left on the nail plate: Correct: massage lotion or oil left on the plate keeps the base coat from bonding, so polish lifts off in whole sheets.

After massage, remove all lotion and oil from the nail plates before base coat; any residue blocks adhesion.

Answer: C

stretch the toe joints.: Separators are not a stretching tool; they simply hold the toes apart.

hold the foot on the footrest.: The footrest or towel supports the foot; separators work between the toes.

keep polished toes apart.: Correct: separators keep the toes from touching so wet polish is not smudged.

prevent ingrown toenails.: Ingrown nails are prevented by trimming straight across, not by separators.

Toe separators keep toes apart during polishing; they are single-use or disinfected depending on material.

Answer: D

Dipping each finger in the jar: Dipping clients' fingers into a shared jar can transfer debris and microorganisms from one client to the next.

Wiping the jar rim after use: Cleaning the rim does not decontaminate the powder that fingers were dipped into.

Sifting used powder back in: Returning used powder to the jar contaminates the supply for future clients.

Pouring powder over the nail: Correct: pouring or sprinkling powder over the nail onto a catch tray keeps clients' fingers out of the shared jar; the used powder is then discarded.

Many states require, and best practice favors, a pour-over method or a single-client portion of powder for dip services.

Answer: A

Coat applied too thickly: Correct: a thick coat cures on the surface before the gel beneath, and the uncured layer shrinks and wrinkles; apply thin coats.

Inhibition layer left on: The inhibition layer is normal between coats and does not cause wrinkling.

Nail dehydrated beforehand: Dehydrating the plate is correct prep and improves adhesion.

Cure time set too long: A longer cure does not wrinkle gel; wrinkling comes from thick coats curing unevenly.

Gel color goes on in thin coats; thick coats cure unevenly and wrinkle.

Answer: C

Apex built in the stress area: An apex in the stress area is correct placement; it strengthens the nail and does not cause cuticle lifting.

Product kept thin near cuticle: Thin product near the cuticle is correct technique for zone 3 and helps prevent lifting.

Cuticle tissue left on plate: Correct: cuticle tissue left stuck to the nail plate prevents a bond, so product placed over it lifts in zone 3 first.

Monomer from a covered dish: Covering the dappen dish limits vapors and contamination; it is not a cause of lifting.

Most early lifting comes from prep: remove cuticle tissue from the plate, remove shine, dehydrate and prime the natural nail.

Answer: D

Air-dried at the station for reuse: A used towel is contaminated even when dry; it must be laundered before reuse.

Sprayed with disinfectant and refolded: Spraying does not clean a porous towel; it must be laundered.

Shaken out and stored in a drawer: Shaking spreads debris and puts soiled linen with clean supplies.

Placed in a closed laundry container: Correct: used linens go into a closed container until laundered, and only clean towels are used for the next client.

Linens are single-use per client: place them in a closed container, launder, and store clean towels covered.
