Which of the following can be a sign of a nail infection?

• A. Bright and shiny nails
• B. Separation of the nail from the nail bed
• C. Uniform thickness across the nail
• D. Consistent nail length

Answer: (B)

Separation of the nail from the nail bed is indeed a sign of a nail infection. This condition, known as onycholysis, occurs when the nail lifts away from its attachment to the nail bed, often allowing bacteria or fungi to enter and cause an infection. This separation can lead to discoloration, pain, and further complications if not treated.

In contrast, bright and shiny nails typically indicate healthy nails rather than an infection. Uniform thickness across the nail is also a characteristic of healthy nails, as any discrepancies in thickness may suggest other issues but not specifically an infection. Additionally, consistent nail length does not point to any signs of infection; in fact, variations in nail length can occur for various reasons unrelated to health. Thus, the visibility of separation is a definitive indicator of potential problems, emphasizing the need for further examination and possible treatment.
