The role of the Adult-Gerontology Nurse Practitioner (AGNP) is to assess, diagnose and plan for the health needs of all adults, from young adults to seniors. Many AGNPs work in long-term care settings, hospital-based clinics and private practices, which may require them to obtain medical histories, perform physical examinations, order screening tests, interpret diagnostic tests and administer age-appropriate pharmacological and non-pharmacological therapies. AGNPs may also manage transitions between care settings, provide patient and caregiver education and evaluate caregiver competence. When providing care, AGNPs consider the environmental, occupational, social and economic background of patients.

The role of a Psychiatric Mental Health Nurse Practitioner (PMHNP) is to assess, diagnose, and treat the mental health needs of patients. Many PMHNPs provide therapy and prescribe medications for patients who have mental health disorders or substance abuse problems. PMHNPs may also provide physical and psychosocial assessments, emergency psychiatric care and treatment effectiveness evaluations.
