- A. Use scissors and trim the toenails in a semicircle.

Correct Answer: D
Rationale: The nurse is correct to instruct the client that proper nail trimming for a client with onychocryptosis is to use a nail clipper and allow the ends of the nail to be longer than the end of the toes.

The nurse is working at a podiatrist's office. Which assessment finding is characteristic to the acquisition of onychomycosis in women?
- A. Clipping nails too closely
- B. Soaking hands in detergent
- C. Wearing artificial nails.
- D. Filing nails even with the fingers
Correct Answer: C
Rationale: The nurse is correct to instruct the client that onychomycosis is frequently found in the fingernails of women wearing artificial nails. Unsanitary cleansing of nail-application utensils between customers in salons seems to be the mode of transmission. Clipping nails too closely can cause discomfort. Soaking hands in detergent and filing nails even with the fingers do not cause onychomycosis.
