Which of the following is a characteristic of a healthy nail?

A characteristic of a healthy nail is the absence of splits or tears. Healthy nails are strong, smooth, and free from damage, which is indicative of good overall health and proper nail care. When nails are in good condition, they maintain their integrity without visible breaks, ensuring that they are less prone to infection or further damage. Having no splits or tears also reflects proper hydration and nourishment of the nail matrix.

In contrast, ridges, discoloration, and a rough texture suggest potential health issues or improper care. Ridges can indicate nutritional deficiencies or other health conditions affecting nail growth. Discoloration may signal fungal infections or exposure to harmful chemicals, while a rough texture points to dryness or damage. Therefore, the characteristic of having no splits or tears clearly aligns with the traits of healthy nails.
