American College of Physicians – “What is an Internist”

“Internists are equipped to handle the broad and comprehensive spectrum of illnesses that affect adults, and are recognized as experts in diagnosis, in treatment of chronic illness, and in health promotion and disease prevention—they are not limited to one type of medical problem or organ system. General internists are equipped to deal with whatever problem a patient brings—no matter how common or rare, or how simple or complex. They are specially trained to solve puzzling diagnostic problems and can handle severe chronic illnesses and situations where several different illnesses may strike at the same time.”

What is a Family Nurse Practitioner

A Family Nurse Practitioner, who may also be referred to by the acronym FNP, is a registered nurse with specialized educational and clinical training in family practice. Nurse practitioners have a higher degree of training, in both the classroom and clinical setting, than Registered Nurses do, although becoming an RN is a prerequisite.

Family Nurse Practitioners in particular are trained to work with both children and adults, most often in the context of a family practice or clinical setting. FNPs work with patients on maintaining health and wellness over the long term with a particular focus on preventative care.
