A cosmetologist is performing a manicure and notices that the client's nails have visible depressions running across the width of the nail plate. This condition is most likely:
- APterygium
- BBeau's lines
- CLeuconychia
- DOnychophagy
Show answer & explanationAnswer & explanation
Correct answer: B. Beau's lines
Beau's lines are visible depressions running across the width of the natural nail plate. They are usually a result of a major illness, injury, or trauma that temporarily impairs nail matrix function.
Why the other options are wrong
- A. Pterygium is the forward growth of the eponychium or hyponychium over the nail plate.
- C. Leuconychia refers to white spots or discoloration on the nail.
- D. Onychophagy is the term for nail biting, not a physical depression.
Beau's Lines
Transverse depressions on the nail plate, indicating a temporary halt or slowing of nail growth.
- Visible horizontal lines/grooves
- Caused by illness, injury, or stress
- Grow out with the nail
Memory trick: Beau's lines across, tell of a past growth loss.
