Who should treat an infected nail?

The correct choice indicates that a physician should treat an infected nail. Physicians have the comprehensive medical training necessary to assess, diagnose, and treat infections, including those affecting the nails. They can prescribe medications such as antibiotics or antifungals as needed, based on the type and severity of the infection. Additionally, a physician can perform any required surgical interventions if the infection has led to more serious complications.

A nurse, while knowledgeable in general health care and patient care, typically works under the supervision of a physician and may not have the authority or expertise to independently treat infections, particularly those requiring specific medical intervention. A nail technician, trained primarily in cosmetic procedures, does not have the medical background or training to safely and effectively manage infections. A dermatologist specializes in skin conditions and may handle nail infections, but the more general designation of physician encompasses all medical practitioners who can provide the appropriate treatment for an infected nail.
