While completing a comprehensive assessment of a client who is admitted with chronic obstructive pulmonary disorder, the objective data revealed the client's nails appear convexed and wide with an angle greater than 160 degrees. How would the nurse document this finding?

A. Beau's lines are horizontal depressions across the nail, unrelated to clubbing. B. Koilonychia refers to spoon-shaped nails, not convexed nails. C. Clubbing is a condition where the nails become convex and the angle between the nail bed and finger increases, often associated with chronic hypoxia or lung diseases like COPD. D. Onycholysis is the separation of the nail from the nail bed, unrelated to convexed nails.
