Free Nail Technician Nail Diseases and Disorders Questions and Answers — Questions and Answers
Question 1: A client presents with redness, swelling, and tenderness of the nail folds on their thumb, with a small amount of pus visible along the lateral edge. Which condition is this, and what is the nail technician's correct course of action?
- Paronychia; refuse the service and recommend the client see a physician. (Correct answer)
- Onycholysis; perform the service but avoid the affected nail.
- Hematoma; gently cleanse the area and proceed with the manicure.
- Pterygium; carefully trim the inflamed tissue and continue the service.
Correct answer: Paronychia; refuse the service and recommend the client see a physician.
The signs described—redness, swelling, tenderness, and pus—are classic indicators of paronychia, a bacterial or fungal infection of the nail fold. As this is an infectious and contagious condition, it is a contraindication for any nail service. The professional and required action is to refuse the service and refer the client to a physician for diagnosis and treatment.
Question 2: Which of the following descriptions most accurately characterizes onychomycosis?
- Vertical ridges and splitting of the nail plate, often associated with aging.
- Separation of the nail plate from the nail bed, creating a white or yellowish pocket.
- Thickening, discoloration (yellow-brown), and crumbling of the nail plate. (Correct answer)
- White spots or streaks within the nail plate, typically caused by minor trauma.
Correct answer: Thickening, discoloration (yellow-brown), and crumbling of the nail plate.
Onychomycosis, or tinea unguium, is a fungal infection of the nail. Its typical presentation includes nail plate thickening, discoloration (often appearing yellow, brown, or white), and a brittle, crumbly, or ragged texture. The other options describe onychorrhexis, onycholysis, and leukonychia, respectively.
Question 3: A client has brittle nails with distinct, lengthwise ridges and is prone to splitting at the free edge. This condition is not contagious and can be serviced with care. What is the correct term for this nail disorder?
- Onychophagy
- Plicatured Nail
- Onychorrhexis (Correct answer)
- Beau's Lines
Correct answer: Onychorrhexis
Onychorrhexis is the medical term for longitudinal (vertical) ridges on the nail plate, which is often accompanied by brittleness and splitting. It is a common condition, especially with age, and is not an infection. Services can be performed gently. Onychophagy is nail-biting, a plicatured nail is folded, and Beau's lines are horizontal depressions.
Question 4: During a consultation, a nail technician observes a dark, vertical band of pigment running the length of a client's nail plate. What is this condition known as, and why does it require a medical referral?
- Hematoma; it indicates old, trapped blood from a previous injury.
- Melanonychia; it can be a potential sign of a serious underlying condition like melanoma. (Correct answer)
- Leukonychia; it is a harmless calcium deposit that will grow out.
- Paronychia; it is a bacterial infection that requires antibiotics.
Correct answer: Melanonychia; it can be a potential sign of a serious underlying condition like melanoma.
This condition is called melanonychia, which is a brown or black pigmented band in the nail. While it can be benign, it is crucial for a nail technician to refer the client to a physician because it can also be an early sign of subungual melanoma, a dangerous form of skin cancer. A technician should never ignore this sign.
Question 5: Which of the following is a nail disorder characterized by the lifting of the nail plate from the nail bed without shedding, typically starting at the free edge and continuing toward the lunula?
- Onychocryptosis
- Pterygium
- Onycholysis (Correct answer)
- Onychomadesis
Correct answer: Onycholysis
Onycholysis is the separation of the nail plate from the underlying nail bed. This creates a space where moisture and debris can collect, but it is not an infection itself. Onychocryptosis is an ingrown nail, pterygium is an overgrowth of the cuticle, and onychomadesis is the complete shedding of the nail plate from the matrix.
Question 6: A nail technician can safely perform a service on a client with which of the following conditions, provided they use gentle techniques and avoid aggravating the area?
- A verruca (wart) on the proximal nail fold.
- Onychomycosis affecting three toenails.
- Acute paronychia with inflammation.
- Eggshell nails (thin, white, and flexible nails). (Correct answer)
Correct answer: Eggshell nails (thin, white, and flexible nails).
Eggshell nails are a disorder where the nail plate is noticeably thin, white, and flexible, curving over the free edge. This condition is not contagious, and services can be performed very gently, often with the recommendation of a nail strengthener. Verruca (viral), onychomycosis (fungal), and paronychia (bacterial/fungal) are all contagious infections and contraindications for service.
