Cosmetology Test Nail Care and Services Questions and Answers — Questions and Answers
Question 1: A client arrives for a manicure with a nail that is thick, yellowish, and appears to be crumbling at the edge. The client states it is not painful. What is the most likely condition and the appropriate course of action for the cosmetologist?
- Pterygium; carefully push back the overgrown cuticle and proceed with the service.
- Bruised nail; gently file the surface and apply a dark polish.
- Onychomycosis; refuse the service and recommend the client see a physician. (Correct answer)
- Onycholysis; proceed with the service but avoid applying product to the affected nail.
Correct answer: Onychomycosis; refuse the service and recommend the client see a physician.
The symptoms described (thick, yellowish, crumbling nail) are characteristic of onychomycosis, a fungal infection of the nail. This condition is contagious and outside the scope of practice for a cosmetologist to treat. The proper protocol is to refuse the service on the affected area to prevent cross-contamination and to recommend the client seek medical attention from a physician.
Question 2: When shaping the free edge of a natural nail during a manicure, which of the following filing techniques is recommended to prevent splitting and damage?
- Using a rapid back-and-forth "sawing" motion across the nail edge.
- Filing deep into the corners on each side of the nail.
- Employing a coarse-grit file (e.g., 100 grit) to speed up the shaping process.
- Filing from the outer corner to the center of the free edge. (Correct answer)
Correct answer: Filing from the outer corner to the center of the free edge.
Filing from the corner to the center of the nail, in one direction, places the least amount of stress on the nail plate. This technique helps to prevent the layers of the nail from separating, which can cause splitting and peeling. A back-and-forth motion weakens the nail, and filing too deeply into the corners can damage the nail bed and lead to ingrown nails.
Question 3: The chemical reaction that occurs when a monomer liquid is mixed with a polymer powder to create a nail enhancement is known as:
- Polymerization (Correct answer)
- Oxidation
- Hydrolysis
- Neutralization
Correct answer: Polymerization
Polymerization is the chemical process where small molecules, called monomers, link together to form long chains, or polymers. In the context of acrylic nails, the monomer liquid reacts with the polymer powder to create the hardened, durable nail enhancement.
Question 4: Which part of the nail unit contains the nerves, lymph, and blood vessels, and is responsible for producing the cells that form the nail plate?
- Eponychium
- Nail Bed
- Lunula
- Matrix (Correct answer)
Correct answer: Matrix
The matrix is the area where nail plate cells are formed and is the living part of the nail. It is located at the base of the nail, under the skin, and contains the blood vessels and nerves necessary for nail growth. Damage to the matrix can affect how the nail grows permanently.
Question 5: A nail technician is performing a repair on a client's natural nail and wants a lightweight, flexible wrap that will become transparent when resin is applied. Which of the following materials, known for its tight weave and natural fibers, would be the most suitable choice?
- Silk (Correct answer)
- Linen
- Paper
- Fiberglass
Correct answer: Silk
Silk wraps are made from a thin, natural material with a tight weave. They are an excellent choice for a lightweight and natural-looking repair because they become transparent when wrap resin is applied. Linen is heavier and opaque, paper is not durable for professional repairs, and fiberglass is a synthetic material, not a natural fiber.
Question 6: A regular client who has diabetes is scheduled for a pedicure. Which implement should be used with extreme caution or completely avoided during this service to prevent injury?
- Foot file or paddle
- Nippers/cuticle cutters (Correct answer)
- Curette
- Wooden pusher
Correct answer: Nippers/cuticle cutters
Clients with diabetes often have compromised circulation and a reduced ability to heal, making them highly susceptible to infections. Using nippers or cuticle cutters poses a significant risk of accidentally breaking the skin, which can lead to a serious infection. It is much safer to gently push back the cuticles rather than cutting them for these clients.
