Which term describes the thickened or abnormally growing nails?

• A. Onychauxis
• B. Onychia
• C. Onychomycosis
• D. Onycholysis

Answer: (A)

The idea tested is nail thickening. Onychauxis describes nails that are abnormally thickened or hypertrophied, which matches “thickened or abnormally growing nails.” The other terms refer to different nail problems: onychia is inflammation of the nail matrix or surrounding tissue; onychomycosis is a fungal infection causing thickened nails; onycholysis is the separation of the nail plate from the nail bed. So, the best fit for thickened nails is onychauxis.
