What is one of the primary roles of a physician?

The primary role of a physician is to diagnose and treat diseases. Physicians are specifically trained to assess patients, interpret medical information, and determine the appropriate course of treatment based on their findings. This involves not only identifying the nature of a patient's illness but also devising a comprehensive treatment plan that may include medication, therapy, or other interventions.

While dispensing medications, administering injections, and supervising nursing staff are important functions in the healthcare setting, they fall under the broader responsibilities of the healthcare team. Physicians often lead this team, but their main focus is on medical diagnosis and patient care. This is why diagnosing and treating diseases is recognized as the fundamental duty of a physician, reflecting their extensive training and expertise in medicine.
