Arkansas Cosmetology License Exam — All Questions

The visible part of the nail that rests on the nail bed is called the nail plate. What is the term for the crescent-shaped, lighter area at the base of the nail?

• a.The free edge
• b.The eponychium
• c.The hyponychium
• d.The lunula✓

The lunula is the whitish, half-moon shape at the base of the nail; it is the visible part of the matrix, where nail cells are produced. The free edge is the part of the nail plate that extends past the fingertip. The eponychium is the living skin (cuticle area) at the base overlapping the plate, and the hyponychium is the skin beneath the free edge. Knowing nail anatomy helps a nail technician work safely without injuring living tissue.

A nail technician should understand the difference between a nail disorder and a nail disease. Which of the following can generally be serviced in the salon?

• a.A nail with signs of active infection, swelling, pus, or inflammation
• b.A noninfectious disorder such as ridges or discoloration✓
• c.A nail with a suspected fungal infection (onychomycosis)
• d.An inflamed, infected area around the nail (paronychia)

A general safety rule: if a nail or skin shows signs of infection or inflammation — redness, swelling, pus, heat, or a suspected fungal or bacterial infection — the client should be referred to a physician and the service should not be performed. Noninfectious cosmetic disorders (such as harmless ridges, minor discoloration, or brittleness) with no signs of infection can usually be worked on and improved cosmetically. When in doubt, do not service and refer out.

To prevent the spread of infection between clients during manicures and pedicures, a nail technician must:

• a.Reuse files and buffers if they still look clean
• b.Rinse metal implements under water only between clients
• c.Discard single-use items and clean and disinfect reusable ones✓
• d.Disinfect the pedicure foot basin once at day's end

Porous, single-use items such as nail files, buffers, and wooden pushers cannot be properly disinfected and must be discarded after one client. Reusable, nonporous metal implements must be cleaned to remove debris and then immersed in an EPA-registered disinfectant for the required contact time. Pedicure foot basins/spas are a known source of infection and must be cleaned and disinfected after every client, following the manufacturer's and regulatory procedures.

New nail cells are produced in which part of the nail unit?

• a.The nail bed, the living skin that the plate slides across as it grows
• b.The hyponychium, the thickened skin located under the free edge
• c.The eponychium, the living skin that overlaps the base of the plate
• d.The matrix, the area under the base of the nail where new cells form✓

The matrix is the only part of the nail unit that produces nail cells; it lies beneath the skin at the base of the nail, and the visible white half-moon at the base is the portion of it that shows through. The cells it makes keratinize and are pushed forward, forming the plate. The nail bed supports and supplies the plate as it slides forward, and the eponychium and hyponychium are skin structures that seal the nail unit at each end.

The pinkish color seen through a healthy natural nail plate comes from:

• a.melanin that is produced by the matrix while the plate is being formed
• b.the many small blood vessels in the nail bed underneath the plate✓
• c.the keratin of the plate itself, which is naturally pink in healthy adults
• d.the thin film of oil left on the plate by the skin around the nail

The nail plate itself is translucent and has no color of its own; the pink appearance comes from the rich blood supply in the nail bed showing through it. That is also why the plate looks white where it grows past the fingertip and no longer sits over the bed, and why a plate lifting away from the bed loses its pink tone. Melanin can produce a pigmented band in some nails, but it is not the source of the normal pink color.

The natural nail plate is composed mainly of:

• a.keratin, the same fibrous protein found in hair and in the skin's surface✓
• b.calcium deposits laid down by the blood vessels of the nail bed below
• c.collagen fibers produced by the reticular layer of the underlying dermis
• d.melanin granules that harden as the nail grows out past the fingertip

The nail plate is made of keratin, a fibrous protein that is also the main component of hair and of the outer layer of the skin. The plate is non-living, hardened tissue, which is why filing and shaping it causes no pain. It is not built from calcium, and the belief that white spots or brittleness indicate a calcium deficiency is a common misconception. Collagen belongs to the dermis, and melanin is pigment rather than structure.

Which statement correctly distinguishes the eponychium from the cuticle?

• a.The eponychium is dead tissue on the plate, while the cuticle is living skin
• b.Both are dead tissue, so both may safely be trimmed away with a nipper
• c.The eponychium is living skin, while the cuticle is dead shed tissue✓
• d.The eponychium lies under the free edge, and the cuticle lines the sidewalls

The eponychium is the band of living skin at the base of the nail that overlaps and seals the plate, and it must never be cut. The cuticle is the dead, colorless tissue shed from the underside of the eponychium that adheres to the surface of the plate; that is the tissue a cuticle remover softens so it can be gently pushed back or removed from the plate. The skin under the free edge is the hyponychium, and the folds beside the plate are the sidewalls.

The hyponychium matters to a nail technician because it:

• a.forms the whitish half-moon shape that is visible at the base of the nail
• b.produces the new nail cells that push the plate out toward the fingertip
• c.anchors the sides of the plate within the grooves beside the nail folds
• d.forms a protective seal under the free edge that guards against infection✓

The hyponychium is the slightly thickened skin beneath the free edge, and it forms a seal that keeps bacteria and other organisms from reaching the nail bed. Cleaning under the free edge too aggressively, or jamming an implement beneath it, can break that seal and open the way to infection. The visible half-moon is the lunula, the matrix produces the new cells, and the sidewalls and grooves hold the plate in place.

The nail folds (sidewalls) and the grooves alongside the nail plate:

• a.hold the plate in place and guide it as it grows toward the free edge✓
• b.manufacture the keratin cells that go on to make up the whole nail plate
• c.supply the plate with blood so that it stays living, flexible tissue
• d.must be scraped out with a metal implement at the start of every service

The nail folds are the folds of skin along the sides of the nail, and the grooves are the tracks between the plate and those folds. Together they frame the plate, hold it in position, and guide it forward as it grows. They do not create nail cells, which is the job of the matrix, and the plate is non-living so it receives no blood. Digging into the grooves with a metal implement can cut living tissue and cause an ingrown nail or an infection.

About how quickly does an average healthy adult fingernail grow?

• a.About one inch per month, roughly the length of a whole fingernail plate
• b.About one-eighth of an inch, or roughly 3 mm, per month✓
• c.About one-eighth of an inch per year, which is why damage lasts so long
• d.About half an inch per month, and noticeably faster in cold weather

The standard figure for an average adult fingernail is roughly one-eighth of an inch, about 3 mm, per month, so replacing an entire plate takes several months. Toenails grow more slowly and are thicker, which is why a damaged toenail takes even longer to grow out. Growth rates vary with age, health, and season, and are generally faster in children and slower in older adults. Knowing the rate helps a technician set realistic expectations when a client asks how long a damaged nail will take to recover.

A client crushed her fingertip months ago, and the nail now grows in with a ridge in the same place every time. The injury most likely damaged the:

• a.free edge, which was torn away and simply has not fully grown back yet
• b.hyponychium, which no longer forms a seal underneath the free edge
• c.matrix, where the plate is formed, so the defect repeats as it grows out✓
• d.nail bed alone, which changes the color of a nail but never its shape

The shape and quality of the plate are determined in the matrix, so an injury there can leave a permanent ridge, split, or deformity that reappears in each new length of nail. Damage confined to the free edge grows out and disappears, and damage to the bed generally affects appearance and adhesion rather than repeating the same defect indefinitely. A technician should work gently over such a nail, avoid heavy filing, and refer the client to a physician if there is any sign of infection.

Which description best matches a healthy natural nail?

• a.Thick and yellow, with the plate lifted away from the bed near the tip
• b.Soft and spongy, with deep grooves running across the width of the plate
• c.Dry and chalky white over the whole plate, with ragged, torn sidewalls
• d.Firm yet flexible and smooth, translucent with a pinkish nail bed✓

A healthy natural nail is firm but flexible, with a smooth, unspotted surface, a translucent plate that shows the pink of the bed beneath it, and intact skin around it. Thickening with yellowing and lifting suggests a fungal infection, and a chalky, crumbling surface or deep transverse grooves point to a disorder or a systemic problem. Recognizing the healthy baseline is what allows a technician to notice when something needs a referral.

White spots that appear within the nail plate, a condition called leukonychia, are usually caused by:

• a.a dietary shortage of calcium that the client should correct with supplements
• b.a fungal organism that requires the client to be referred to a physician
• c.minor injury to the matrix at the time that part of the plate was forming✓
• d.repeated contact with water, which bleaches the surface of the plate

Leukonychia is the white spotting seen in many otherwise healthy nails, and it generally follows a small bump or injury to the matrix while that section of plate was being formed. The spots are harmless, they cannot be buffed away because they are inside the plate, and they simply grow out with the nail. Despite a widespread belief, they are not evidence of a calcium deficiency, and they are not a fungal infection, so the nail can be serviced normally.

Onychophagy is the technical term for:

• a.bitten nails, in which the plate and the skin around it are chewed short✓
• b.split, brittle nails that show a series of lengthwise ridges in the plate
• c.an inflammation of the tissues that surround the sides of the nail plate
• d.an abnormal growth of skin that stretches forward and sticks to the plate

Onychophagy is the habit of biting or chewing the nails and often the surrounding skin, leaving short, ragged plates. It is a disorder rather than an infection, so the nails may be serviced, and regular manicures or enhancements often help a client break the habit as long as the skin is not broken or infected. Lengthwise splitting and brittleness is onychorrhexis, inflammation of the surrounding tissue is paronychia, and forward-growing adherent skin is pterygium.

A client's nails are brittle and split lengthwise with visible vertical ridges, a condition called onychorrhexis. This is often linked to:

• a.a bacterial infection under the plate that is spreading toward the matrix
• b.aggressive filing and repeated exposure to solvents or harsh cleaners✓
• c.the natural pink of the nail bed showing through an unusually thin plate
• d.shoes that are too tight, pressing the plate down into the side grooves

Onychorrhexis describes brittle nails with lengthwise ridges and splits. It is commonly associated with careless or heavy-handed filing, over-aggressive removal of enhancements, and frequent contact with solvents, polish removers, and household cleaners, though illness and heredity can play a part as well. It is a disorder rather than an infection, so the nails can be serviced with gentle filing, conditioning oil, and protection from chemicals. Tight shoes are a factor in ingrown toenails, not in lengthwise splitting.

A hangnail is best described as:

• a.a nail plate that has separated from its bed beginning at the free edge
• b.a dark band of pigment that runs from the matrix toward the free edge
• c.a series of depressions running across the plate after a serious illness
• d.living skin around the nail that has split or torn away from the plate✓

A hangnail, also called an agnail, is a split or torn piece of the living skin beside the nail, usually the result of dryness or of cuticle tissue being cut or picked. It is a common disorder that can be serviced: soften the area, trim only the torn dead flap, and apply conditioning oil. If the area becomes red, swollen, or tender, it may have become infected, and the client should be referred to a physician instead of serviced.

Visible depressions running across the width of the nail plate, known as Beau's lines, generally follow:

• a.an illness, injury, or other stress that briefly interrupted nail growth✓
• b.the daily use of a nail hardener that contains a strengthening resin
• c.an allergic reaction to the polish applied at the previous appointment
• d.normal aging, which gradually flattens the plate from one side to the other

Beau's lines are grooves that run across the nail from side to side, and they appear when growth at the matrix was slowed or halted for a time by a systemic illness, high fever, injury, or other significant stress. They grow out with the nail. The nails may be serviced gently, but a technician should never speculate about the underlying cause to the client; if the lines are unexplained or affect many nails, suggesting a visit to a physician is appropriate.

Pterygium, an abnormal stretching of skin that adheres to the surface of the nail plate, should be handled by:

• a.cutting the adhering tissue away with a nipper to free the plate underneath
• b.pushing it back forcefully with a metal pusher at every single appointment
• c.treating it gently without cutting, and referring the client if it is severe✓
• d.applying a strong cuticle remover and leaving it in place for about an hour

Pterygium is living tissue that has grown abnormally forward and attached itself to the plate, often after an injury or a burn. Because it is living skin, cutting it or forcing it back causes injury, bleeding, and possible infection, and it tends to worsen the condition. The professional response is conditioning oil, gentle massage, and no cutting, with a referral to a physician when the condition is significant. This is different from ordinary cuticle tissue, which is dead and may be removed from the plate.

A client has a dark spot under one nail that she cannot account for and that she says has been changing. The technician should:

• a.buff the surface of the plate until the discoloration is no longer visible
• b.cover the area with an opaque polish and carry on with the scheduled service
• c.identify it as a simple bruise and reassure her that it will grow out soon
• d.avoid naming any condition and suggest that a physician look at the nail✓

Dark discoloration under a nail is often a bruise, a pooling of blood after an injury, and a band of pigment called melanonychia is also common in some nails. However, an unexplained or changing dark area can be a sign of a serious condition, and a nail professional is not qualified to tell those apart. The correct action is to stay within scope: do not diagnose, do not attempt to buff or disguise it, and tactfully recommend that a physician evaluate it.

Onychomycosis is:

• a.a fungal infection of the nail that must be referred to a physician✓
• b.a harmless thickening of the plate that responds well to careful buffing
• c.an inflammation of the skin folds caused by cutting into the eponychium
• d.the technical term for a nail plate that has been bitten down very short

Onychomycosis is a fungal infection of the nail unit, often producing yellowing, thickening, crumbling, and separation of the plate from the bed. Because it is an infection, the service should be declined and the client referred to a physician; buffing or covering it can spread the organism and delay real treatment. Inflammation of the tissue around the nail is paronychia, and bitten nails are onychophagy. The general rule is that a disorder may be serviced with care, but an infection is referred out.

The skin around a client's fingernail is red, swollen, warm, and tender. This suggests paronychia, so the technician should:

• a.soak the finger in warm soapy water and then push the swollen area back
• b.decline service on that nail and refer the client to a physician for care✓
• c.apply an antiseptic and continue, since the plate itself still looks normal
• d.trim the swollen tissue away carefully with a freshly disinfected nipper

Paronychia is an inflammation and infection of the tissue surrounding the nail, and the classic signs are redness, swelling, warmth, tenderness, and sometimes pus. Any of those signs contraindicates the service. Working on the area, pushing it back, or cutting it can drive the infection deeper and spread it, and applying an antiseptic is a treatment a cosmetologist is not there to provide. Decline the service, explain that the area needs medical attention, and disinfect anything that made contact.

Onychia, an inflammation of the nail matrix and the tissue around it, sometimes with pus present, is:

• a.a disorder that will improve after a series of strengthening treatments
• b.a normal response to a fill that only calls for a lighter touch next time
• c.an infection that contraindicates the service and calls for a referral✓
• d.the result of a vitamin deficiency and unrelated to anything in a salon

Onychia is an inflammation of the matrix and surrounding tissue, with redness, swelling, and often pus, and it can follow an injury or an implement being pushed into living tissue. It is an infection, not a cosmetic disorder, so the service must not be performed and the client should be referred to a physician. Strengthening treatments and a gentler touch do not address an infection, and calling it a nutritional problem would be diagnosing, which is outside a nail professional's scope.

A greenish-black discoloration is found on the nail plate when a lifted enhancement is removed. This is:

• a.mold growing on the plate, which can be safely sealed under new product
• b.a stain from dark polish that will lift with acetone and some light buffing
• c.harmless oxidation of the enhancement product and no cause for concern
• d.a bacterial infection that calls for a referral, not more product✓

The green or greenish-black discoloration that appears between an enhancement and the natural plate is caused by bacteria, commonly pseudomonas, that multiplied in the moisture trapped under a lifted area. It is frequently but wrongly called mold. Applying more product over it seals the moisture and bacteria in and makes the problem worse. Remove the enhancement, and refer the client to a physician rather than attempting to treat or disguise the area; then clean and disinfect implements thoroughly.

Which statement correctly contrasts onycholysis with onychomadesis?

• a.Onycholysis lifts the plate from its bed, while onychomadesis separates it at the base✓
• b.Onycholysis is a fungal infection of the plate, while onychomadesis is an allergic reaction
• c.Onycholysis is white spotting, while onychomadesis is a lengthwise splitting
• d.Onycholysis is an ingrown nail, while onychomadesis is an inflamed nail fold

Onycholysis is the lifting of the nail plate away from the bed, usually beginning at the free edge, without the plate falling off; it can follow injury, an allergic reaction, or an infection. Onychomadesis is separation and shedding of the plate starting at the base, at the matrix end. Both leave the nail unit open to infection, so a technician should not apply product over the area and should refer the client to a physician when the cause is unclear or there are signs of infection.

Onychocryptosis, an ingrown nail, most often results from:

• a.trimming a toenail straight across instead of rounding it deeply at the corners
• b.improper filing or trimming down into the corners, together with tight shoes✓
• c.a fungal organism that grows under the plate and forces it sideways
• d.using a wooden pusher rather than a metal one on the cuticle tissue

An ingrown nail occurs when the edge of the plate grows into the surrounding skin, and the usual causes are filing or cutting down into the corners so a spur is left behind, along with pressure from narrow shoes. Trimming toenails straight across is the recommended practice precisely because it helps prevent this. A technician may gently smooth and shape a mild case, but if the area is red, swollen, painful, or draining, the client must be referred to a physician.

When shaping a client's natural nails with an abrasive file, the technician should:

• a.saw the file back and forth quickly in order to shorten the free edge faster
• b.hold the file flat on the plate and file straight into the side groove
• c.file the surface of the plate first to thin it before shaping the free edge
• d.file from each outer corner in toward the center, working in one direction✓

Filing a natural nail from the outside corner toward the center, in one direction on each side, keeps the layers of the plate from separating. Sawing back and forth generates heat and friction that splits and frays the free edge, especially on thin or brittle nails. Filing into the groove risks cutting the living skin at the sidewall, and thinning the surface of a natural plate weakens it. A gentler abrasive is chosen for natural nails than for enhancements.

During a manicure, cuticle remover is applied and the tissue is gently pushed back. The technician must NOT:

• a.use a wooden or rubber-tipped pusher held at a low angle to the plate
• b.rinse the remover off thoroughly once the tissue has been loosened
• c.cut into the living skin of the eponychium to expose more of the plate✓
• d.apply conditioning oil to the area at the end of the manicure service

Cuticle remover softens the dead cuticle tissue that adheres to the surface of the nail plate so it can be eased back or wiped away. The living skin of the eponychium is never cut: cutting it breaks the seal that protects the matrix and invites infection, bleeding, and thickened regrowth. Using a soft-tipped pusher at a shallow angle, rinsing the product off so it does not keep working on the skin, and finishing with oil are all correct steps.

A pedicure client mentions that she is diabetic and she has thick calluses on both heels. The technician should:

• a.work gently with a foot file and suggest that she consult her physician✓
• b.use a credo blade to shave the calluses down to soft skin very quickly
• c.soak the feet in the hottest water available so the tissue softens faster
• d.massage the legs vigorously in order to increase the circulation in her feet

Clients with diabetes or impaired circulation may have reduced sensation in the feet and heal slowly, so even a small nick can become a serious infection. Services should be gentle: no cutting or shaving of callused tissue, careful water temperature checked with a thermometer rather than by feel alone, light massage, and a referral to a physician for anything beyond routine care. Most state boards prohibit the use of a credo blade or any razor-type implement for callus removal because of the risk of cutting living tissue.

Which sequence reflects the standard order of a basic manicure?

• a.Massage, polish, remove the old polish, shape the nails, push back the cuticle
• b.Remove the old polish, shape the nails, push back the cuticle, massage, polish✓
• c.Shape the nails, polish, remove the old polish, massage, push back the cuticle
• d.Polish, massage, push back the cuticle, remove the old polish, shape the nails

A basic manicure starts by removing any existing polish so the natural nails can be examined for disorders and infection. The free edges are then shaped and smoothed, the hands are soaked or the cuticle area is softened and gently pushed back, and the hand and arm are massaged. Polish goes on last, after the nail plates are cleaned of any oil left by the massage, so that base coat, color, and top coat adhere properly.

In a two-part acrylic (methacrylate) enhancement system, the product hardens because:

• a.the liquid evaporates away and leaves the polymer powder packed onto the nail plate
• b.the primer bonds the powder to the plate and prevents any chemical change
• c.the monomer liquid and the polymer powder react and polymerize into long chains✓
• d.ultraviolet light causes the powder to melt and then fuse onto the surface

An acrylic enhancement is created by a chemical reaction: the monomer liquid and the polymer powder are combined, and an initiator in the powder starts polymerization, linking the small monomer molecules into very long chains that harden into a solid. Nothing simply dries or evaporates, and a traditional acrylic cures on its own without a lamp. Primer improves adhesion between the natural plate and the product but is not what hardens it.

A UV or LED gel enhancement cures when:

• a.photoinitiators in the gel absorb light energy and set off polymerization✓
• b.a chemical activator brushed over the gel sets the product on contact
• c.the gel is left exposed to the air for several minutes and its solvent evaporates
• d.a fabric wrap placed beneath the gel absorbs the resin and hardens around it

UV and LED gels contain photoinitiators that absorb energy at specific wavelengths from the lamp and trigger polymerization, hardening the gel in the lamp rather than in open air. Each gel must be cured in the lamp the manufacturer specifies, because the wavelengths and timing differ. Wrap systems are a different technology, in which a fabric is adhered with a resin and set with an activator, and dip systems use a resin with a powder rather than a lamp.

Why must an acid-based nail primer be used sparingly and handled with care?

• a.It dries so slowly that the enhancement cannot be applied for several hours
• b.It removes surface moisture and oil, which is the job of a nail dehydrator
• c.It permanently bleaches the natural nail plate a chalky white wherever it touches
• d.It is corrosive to skin and eyes, so contact with living tissue must be avoided✓

Acid-based primers contain methacrylic acid, which is corrosive: it can burn skin and eyes, so it is applied only to the natural plate in the smallest effective amount, never flooded onto the surrounding skin, and it is handled with appropriate protective equipment and stored closed. Acid-free primers are less aggressive and are widely used instead. A nail dehydrator is a separate product that removes surface moisture and oil before priming, and neither product bleaches the plate.

Methyl methacrylate (MMA) monomer is widely regarded in the professional nail industry as:

• a.the preferred monomer, because it bonds more gently than the other liquids
• b.unsuitable for nail enhancements, being too rigid and adhering too aggressively✓
• c.an acceptable substitute whenever a client has thin or sensitive natural nails
• d.the only monomer that will cure under an LED lamp without any primer at all

MMA is not accepted for use in nail enhancements. The product cures extremely hard and inflexible and bonds so tightly to the natural plate that, when the enhancement is struck, the natural nail tears rather than the enhancement breaking away, and removal typically requires heavy filing that damages the plate. Ethyl methacrylate (EMA) is the monomer used in professional products. Warning signs of MMA include an unusually strong odor and an enhancement that will not soak off in acetone.

Which practice best reduces a nail technician's daily exposure to product vapors and filing dust?

• a.Leaving the product containers open so that the vapors can disperse into the room air
• b.Wearing a dust mask only, on the basis that vapors are not inhaled at all
• c.Keeping containers closed, using local ventilation, and wearing a mask when filing✓
• d.Running a small desk fan that pushes the air from the table across toward the client

Exposure is controlled at the source: keep monomer, primer, and remover containers closed when not in use, dispense small amounts, discard used wipes in a covered metal container, and use a ventilation system that pulls vapors and dust away from the breathing zone rather than simply stirring the air. A dust mask helps with filing particles but does not filter vapors. Blowing air toward the client only moves the exposure to someone else.

At an enhancement maintenance appointment (a fill or rebalance), the technician should:

• a.file the natural nail plate thin so that the fresh product will adhere better
• b.apply new product over any lifted areas to save the time of re-prepping them
• c.soak off the whole enhancement and start again from bare nails every time
• d.remove lifted product and blend the regrowth area without thinning the plate✓

A fill or rebalance addresses the new growth at the base: lifted product is removed, the ledge between old product and regrowth is blended smooth, the exposed natural plate is lightly prepared, and fresh product is applied and rebalanced. Filing into the natural plate thins and weakens it and can create rings of fire and permanent damage. Applying product over a lifted area traps moisture and bacteria underneath, and a complete removal at every visit is unnecessary and hard on the nail.
