A nurse practitioner (NP) is an advanced practice registered nurse and a type of mid-level practitioner. NPs are trained to assess patient needs, order and interpret diagnostic and laboratory tests, diagnose disease, prescribe medications and formulate treatment plans. NP training covers basic disease prevention, coordination of care, and health promotion.

Primary care is the day-to-day healthcare given by a health care provider. Typically this provider acts as the first contact and principal point of continuing care for patients within a healthcare system, and coordinates other specialist care that the patient may need. Patients commonly receive primary care from professionals such as a primary care physician, a physician assistant, a physical therapist, or a nurse practitioner. In some localities, such a professional may be a registered nurse, a pharmacist, a clinical officer, or an Ayurvedic or other traditional medicine professional. Depending on the nature of the health condition, patients may then be referred for secondary or tertiary care.
