Question 1 of 10
The region highlighted in yellow under the free edge of the nail is called the:
A Matrix
B Free edge
C Cuticle
D Hyponychium
Explanation
The hyponychium is the thickened skin underneath the free edge of the nail. It forms a protective seal that blocks bacteria and debris from entering under the nail plate.
Question 2 of 10
The condition shown — separation of the nail plate from the nail bed starting at the free edge — is called:
A Onychorrhexis
B Onychocryptosis
C Onychogryphosis
D Onycholysis
Explanation
Onycholysis is the painless separation of the nail plate from the bed (without shedding). Causes include trauma, fungal infection, certain medications, or chemicals. Suspicious cases — especially with discoloration — should be referred to a doctor.
Question 3 of 10
MMA (methyl methacrylate) is:
A Only allowed for pedicures
B The current standard for safe nail enhancements
C A type of UV gel
D Banned by most state boards including Texas TDLR for nail use
Explanation
MMA causes severe allergic reactions, nail damage, and is extremely difficult to remove. EMA (ethyl methacrylate) is the legal alternative. Use of MMA can cost you your license.
Question 4 of 10
California nail technician licenses are issued by:
A California Board of Barbering and Cosmetology (BBC)
B Local city government
C Texas Department of Licensing and Regulation
D US Department of Labor

Question 5 of 10
What is the most effective way to prevent the spread of infection in a nail salon?
A Hand washing with soap and water
B Wiping tools with alcohol pads
C Using antibacterial sprays
D Wearing latex gloves at all times
Explanation
Frequent and thorough hand washing is universally recognized as the single most effective infection-control measure. Gloves and disinfectants are supplements, not substitutes.
Question 6 of 10
Looking at the polish stroke diagram, in what order should the three strokes be applied for an even coat?
A 1 → 2 → 3 (center first, then both sides)
B 2 → 1 → 3 (left side, then center, then right)
C Random — order does not matter
D 1 → 3 → 2 (center, right, then left)
Explanation
Standard 3-stroke technique: load the brush, place it just above the cuticle in the CENTER of the nail (stroke 1), then sweep down each SIDE (strokes 2 and 3). Center first ensures the most polish lands on the visual focal point and the sides blend into it for an even, professional finish.
Question 7 of 10
A whirlpool foot spa must be cleaned and disinfected:
A After each client
B Only when visibly dirty
C Once a week
D Once a day at closing
Explanation
Texas TDLR requires foot spas to be cleaned and disinfected after EVERY client, with a more thorough weekly disinfection and a documented log.
Question 8 of 10
In the cross-section illustration above, which structure is responsible for producing new nail cells?
A Matrix
B Hyponychium
C Free edge
D Nail bed
Explanation
The matrix is the active cell-producing tissue at the base of the nail. Damage here can permanently deform the nail.
Question 9 of 10
A client wants the strongest natural nail shape for daily typing work. Which shape is the WORST choice?
A C (round)
B B (oval)
C D (stiletto / pointed)
D A (square)
Explanation
Stiletto/pointed shapes (D) are the most fragile because most of the nail extends past the support of the nail bed and the narrow point concentrates stress. For a typist or client doing daily manual work, stiletto natural nails will chip, split, or break constantly. Suggest an oval or short squoval instead.
Question 10 of 10
This severely thickened, curled, ram's-horn-shaped toenail condition is called:
A Onychogryphosis
B Onycholysis
C Onychomycosis
D Koilonychia
Explanation
Onychogryphosis ("ram's horn nail") is severe nail thickening and curvature, most often on the big toe. Causes include long-term neglect, trauma, or poor circulation in elderly clients. Refer to a podiatrist — do NOT attempt to file or cut down in the salon.
