Question 1

What is the technical term for the most visible part of the nail plate?

Accepted Answer

The free edge is the distal portion of the nail plate that extends beyond the fingertip. It is the part that is filed, shaped, and polished. The nail bed lies beneath the plate, the matrix produces new nail cells, and the lunula is the white half-moon at the base.

Question 2

What nail disorder appears as white spots or streaks on the nail plate?

Accepted Answer

Leukonychia is a nail disorder characterized by white spots or streaks on the nail plate. It is usually caused by minor trauma to the nail matrix. It is not contagious and grows out on its own over several weeks.

Question 3

Onychomycosis is most commonly treated with:

Accepted Answer

Onychomycosis (nail fungus) requires prescription antifungal treatment — either oral (like terbinafine) or topical (like ciclopirox). Cosmetic products cannot cure nail fungus. Cosmetologists must refuse service on infected nails.

Question 4

Which nail shape is considered the strongest because it follows the natural nail shape?

Accepted Answer

The oval nail shape is considered the strongest because it follows the natural lateral line of the nail, distributing stress evenly. Pointed shapes concentrate stress at the tip and break more easily. Square shapes can snag.

Question 5

What should a cosmetologist do if a client arrives with signs of an acute nail infection (paronychia)?

Accepted Answer

Paronychia (bacterial or fungal infection of the skin around the nail) contraindicates any nail service. The cosmetologist should refuse service and refer the client to a physician for medical treatment.

Question 6

A cosmetology student applies acrylic nail product directly to a client's skin. What is the primary risk?

Accepted Answer

Acrylic monomer (liquid) is a known sensitizer. Repeated skin contact can cause allergic contact dermatitis and, once sensitized, the client may react to any acrylic product for life. Product should only be applied to the nail plate, not skin.

Question 7

What is the correct nail file motion when shaping natural nails to prevent splitting or peeling?

Accepted Answer

Filing in one direction (corner to center) prevents the heat and micro-fractures caused by back-and-forth sawing. Sawing creates friction that can separate the nail layers (peeling) and weaken the free edge. Finer grits (180+) are preferred for natural nails.

Question 8

In a basic manicure, what is the purpose of applying cuticle remover (softener)?

Accepted Answer

Cuticle removers contain alkaline ingredients (e.g., potassium hydroxide) that soften dead cuticle tissue (eponychium residue) on the nail plate, making it easy to gently push back and remove without cutting live tissue — reducing infection risk.

Question 9

Which nail condition is characterized by a white, chalky discoloration of the nail plate, often caused by previous acrylic or gel removal?

Accepted Answer

Keratin granulation appears as rough, white patches on the nail plate, commonly caused by improper removal of gel or acrylic enhancements that strip surface keratin layers. It is not a disease — it is cosmetic damage that grows out. Leukonychia (white spots) has different causes.

Question 10

A client asks for a gel manicure. When curing UV/LED gel polish, what is the most important safety precaution?

Accepted Answer

UV/LED curing lamps emit UV radiation that can cause cumulative skin damage. Research supports applying broad-spectrum SPF 30+ sunscreen or wearing UV-protective fingerless gloves before each lamp cure to minimize skin cancer risk — especially for frequent clients.
