The Family Nurse Practitioner role emphasizes health promotion, health maintenance, prevention and detection of alterations in health through supportive interventions, counseling, and teaching of families and individuals. In addition, the Family Nurse Practitioner role includes aspects of illness care management that include diagnosis and management of common, chronic, and acute conditions. The practitioner acknowledges and recognizes limitations in the scope of practice, collaborates and consults with other health care providers. Family Nurse Practitioner practice is based on an epidemiological approach to health problems, an understanding of family and community systems, the management of resources and economics, and the use of appropriate technology.

Family Nurse Practitioners improve access to primary care for all populations, especially those considered under-served, whether inner city, suburban, or rural. The Family Nurse Practitioner may provide care to families and individuals in a variety of settings, including the home, school, workplace, or hospital, depending on client needs. The practitioner's function in each setting may vary and include care in a specific specialized area.
