NIC Nail Technician Written ExamScientific ConceptsEasy

A client asks about the 'white spots' on their fingernails, which appear as small, opaque, white discolorations. They are concerned it might be a fungal infection. What is the most common and generally harmless cause of these white spots?

  1. AOnychomycosis
  2. BPsoriasis
  3. CMelanonychia
  4. DLeukonychia
Show answer & explanation

Correct answer: D. Leukonychia

Leukonychia, or white spots, are common and usually harmless, resulting from minor trauma to the nail matrix during nail growth. They are not typically indicative of a fungal infection.

Why the other options are wrong

  • A. Onychomycosis is a fungal infection, usually causing yellow, brown, or thickened nails, not typically small white spots.
  • B. Psoriasis can affect nails, causing pitting, discoloration, and thickening, but not typically small white spots.
  • C. Melanonychia is a brown or black discoloration of the nail, often appearing as a stripe, not white spots.

Leukonychia

White discoloration of the nail, commonly appearing as small spots or lines, usually harmless and caused by minor trauma to the nail matrix.

  • Often due to minor injury to the nail matrix.
  • Moves with nail growth.
  • Generally benign and does not require treatment.

Memory trick: White is Light, no plight.
