1. What is the technical term for the nail’s natural attachment of the nail bed and matrix to
the underlying bone?
A. Specialized ligaments
B. Eponychium
C. Hyponychium
D. Bed epithelium
Answer: A
Conceptual Explanation: Specialized ligaments are tough bands of fibrous tissue that
connect the nail bed and the matrix bed to the underlying bone.
2. Which nail disorder is characterized by a dramatically increased curvature of the nail, often
caused by injury to the matrix?
A. Onychocryptosis
B. Onychogryposis
,C. Plicatured nail
D. Paronychia
Answer: C
Conceptual Explanation: Plicatured nail, often called folded nail, is a type of highly curved
nail plate usually caused by injury to the matrix, though it may be inherited.
3. In nail chemistry, what is the role of a photoinitiator in UV-cured gels?
A. To increase the viscosity of the gel
B. To prevent the gel from yellowing
C. To evaporate the solvent from the product
D. To trigger the polymerization process when exposed to light
Answer: D
Conceptual Explanation: A photoinitiator absorbs specific wavelengths of light (UV or
LED) and begins the chemical reaction that turns the liquid gel into a solid polymer.
4. Which bacterial infection is most likely to be indicated by a green discoloration underneath
a nail enhancement?
A. Tinea unguium
B. Staphylococcus aureus
C. Candida albicans
, D. Pseudomonas aeruginosa
Answer: D
Conceptual Explanation: Pseudomonas aeruginosa is a common bacterium that can lead
to a bacterial infection appearing as a green, yellow, or black discoloration on the nail bed.
5. The active ingredient in most nail bleaches is usually:
A. Ammonia
B. Sodium hydroxide
C. Hydrogen peroxide
D. Isopropyl alcohol
Answer: C
Conceptual Explanation: Nail bleaches typically contain hydrogen peroxide or organic
acids to remove surface stains from the nail plate.
6. Which of the following is the most common muscle of the forearm that rotates the palm
upward?
A. Supinator
B. Pronator
C. Flexor
D. Extensor
