Cosmetology Test Nail Care and Procedures Questions and Answers — Questions and Answers
Question 1: A client presents with a nail plate that is noticeably thickened, discolored with a yellowish hue, and appears to be separating from the nail bed. The client states the condition is not painful. What is the most appropriate action for the cosmetologist?
- Perform the service but use a gentle file and avoid applying polish.
- Refuse the service on the affected nail and recommend the client see a physician. (Correct answer)
- Soak the nail in a strong antiseptic for ten minutes before proceeding.
- Apply a nail dehydrator and a strengthening base coat to the nail.
Correct answer: Refuse the service on the affected nail and recommend the client see a physician.
The symptoms described (thickening, discoloration, separation from the nail bed) are classic signs of a potential fungal infection (onychomycosis) or other nail disease. Cosmetologists are not licensed to diagnose or treat medical conditions. The scope of practice requires them to refuse service on any nail that shows signs of infection or disease and to refer the client to a medical professional for diagnosis and treatment.
Question 2: 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
- Nail Matrix (Correct answer)
- Hyponychium
Correct answer: Nail Matrix
The nail matrix is the area of living tissue at the base of the nail that is responsible for all nail growth. It contains the blood vessels and nerves that provide nourishment and produces the keratin cells that harden and grow out to become the nail plate. The nail bed supports the nail plate, but does not produce it. The eponychium is the living skin at the base of the nail plate, and the hyponychium is the skin under the free edge.
Question 3: When applying acrylic nail enhancements, the chemical reaction that occurs when the liquid monomer is mixed with the polymer powder to form a hardened nail is called:
- Polymerization (Correct answer)
- Oxidation
- Dehydration
- Neutralization
Correct answer: Polymerization
Polymerization is the chemical process in which small molecules called monomers link together to form long chains called polymers. In acrylic application, the liquid monomer reacts with the polymer powder, initiating this process to create the hard, durable acrylic nail enhancement.
Question 4: A regular client who has diabetes comes in for a pedicure. Which of the following actions is a critical safety precaution the nail technician must take?
- Soak the feet in extra-hot water to soften the skin effectively.
- Use a coarse, abrasive file to vigorously remove all calluses.
- Avoid using sharp implements, such as metal nippers or credo blades, near the skin. (Correct answer)
- Apply a generous amount of moisturizing lotion between the toes to prevent dryness.
Correct answer: Avoid using sharp implements, such as metal nippers or credo blades, near the skin.
Clients with diabetes often have compromised circulation and reduced nerve sensation (neuropathy), meaning they may not feel a cut or injury. A small cut from a sharp tool like a nipper or a credo blade (which is illegal in many states) can be very slow to heal and may lead to a serious infection. Therefore, cosmetologists must avoid any implements that could break the skin. Gentle filing and pushing back cuticles without cutting are the safest methods.
Question 5: What is the primary function of applying a nail primer to the natural nail plate before an acrylic nail service?
- To provide a high-gloss shine to the finished enhancement.
- To act as a disinfectant and kill bacteria on the nail surface.
- To improve the adhesion between the natural nail and the acrylic product. (Correct answer)
- To temporarily harden the natural nail before application.
Correct answer: To improve the adhesion between the natural nail and the acrylic product.
A nail primer is a crucial step for ensuring the longevity of acrylic nails. Its main purpose is to act as a bonding agent that improves the adhesion of the acrylic enhancement to the natural nail plate. It does this by creating a surface that the acrylic can bond to more effectively, which helps to prevent lifting and peeling.
Question 6: During a nail wrap service, which of the following fabrics is known for being the thinnest and most transparent, becoming nearly invisible on the nail once resin is applied?
- Silk (Correct answer)
- Linen
- Fiberglass
- Paper
Correct answer: Silk
Silk wraps are made from a thin, natural material with a tight weave. Because of its fine texture, silk becomes transparent when nail resin is applied, making it an excellent choice for a very natural-looking nail repair or overlay that is lightweight and flexible.
