The term Onychosis refers to what?

• A. Any nail disease, disorder, or condition
• B. A disease of the skin
• C. An infection of the nail bed
• D. A fracture of the nail

Answer: (A)

Onychosis is the general term for any nail disease, disorder, or abnormal condition. It indicates that something is affecting the nail itself in some way—whether in shape, color, thickness, or growth—without labeling a specific problem. The other options point to particular issues: a disease of the skin refers to skin pathology, not the nail; an infection of the nail bed is a specific infection; a fracture is a physical injury. Because onychosis covers any nail-related abnormality, it’s the most inclusive and best-fitting choice.
