nurse practitioner (NP), a registered nurse who has advanced education in nursing (a master’s of science in nursing or a doctorate in nursing practice) and clinical experience in a specialized area of nursing practice. NPs are certified by passing an examination administered by a professional organization such as the American Nurses’ Credentialing Center. They collaborate with other health care providers to deliver primary care to patients with common acute or stable chronic medical conditions in ambulatory care settings. Some NPs also function in a specialty, tertiary, or long-term care setting. NPs may offer a variety of services, such as complete physical examinations, health assessments, and patient education. Specialty certification is required. The scope of all advanced nursing practice is influenced by state laws, federal laws, insurance practices, and regional acceptance. Some insurance organizations recognize NPs as primary health care providers and allow direct reimbursement for their services.
