Nurse practitioner graduate degree programs are typically designed to help healthcare professionals like registered nurses enhance their ability to provide treatment to patients. Nurse practitioners (NPs) are advanced practice registered nurses (APRN) who have completed graduate level education beyond that required of the generalist registered nurse (RN) to provide care to patients throughout their lifespan, from infants to the elderly. They promote a comprehensive approach to health care by educating patients and their families on prevention and health management. A nurse practitioner's role may include diagnosing and treating diseases, conducting physical examinations, ordering and analyzing diagnostics studies, prescribing medication, providing immunizations, providing well visit care, and counseling patients. Nurse practitioner programs usually include courses in epidemiology, advanced pathophysiology, advanced pharmacology, laboratory/radiography diagnostics, statistics and research methods, health policy, role development and leadership, disease management, and clinical rotations. Nurse practitioner degrees can be focused in these main areas: adult (ANP); acute care (ACNP); gerontological (GNP); family (FNP); pediatric (PNP); neonatal (NNP); and psychiatric - mental health (PMHNP).
