A: Doctors are formally trained in medicine, meaning the treatment of disease through medication, medical procedure and sometimes surgery.

Nurse practitioners, who also are registered nurses, are formally trained in caring for the sick and have knowledge of how to diagnose, treat and manage many common ailments.

In many cases, they perform the same functions:

Identify and treat acute and chronic illnessesOrder and analyze labs and other diagnostic testsPrescribe medications.

Where doctors and nurse practitioners differ most is in the time spent on their respective educations and the types of patients they typically choose to see.

Physicians spend more time in school and conduct deeper study of diseases. Many physicians will identify a specific area or specialty that they have the most knowledge or interest in to pursue as a career.

Nurse practitioners also focus heavily on education. They often complete graduate-level courses and can spend hundreds of hours performing supervised clinical work. But they see patients at every phase of their lives, and typically don’t specialize in any one area. They can function well as primary care providers because their background includes knowledge of both holistic and wellness-oriented programs, which spotlight education, risk identification and preventative care.
