Nurse practitioners (NPs) are healthcare providers independently licensed to provide a range of medical and nursing services to patients in varied settings.  NPs are licensed to conduct diagnostic studies, determine medical diagnoses, prescribe pharmacologic and non-pharmacologic treatments, and educate patients.  NPs are prepared and practice in specified "population foci".  The vast majority of NPsare prepared in foci emphasizing primary care, e.g. adult, family, gerontological, pediatric, and women's health.  NPs practice in a range of settings, including private practices, hospital owned outpatient and inpatient settings, community health, and many others. Almost 50 years of research supports the quality of NP care in varied settings.  INPE provides a range of information regarding NPs and their practice.  More information will be added over time.
