A nurse practitioner's responsibilities depend on the work setting and area of specialization. A nurse practitioner may work in close collaboration with a physician at a hospital, health center, or private practice office. Sometimes, as in the case of rural health care providers, they many have only weekly telephone contact with a physician. Some states allow nurse practitioners to function entirely independent of a physician. In all states, a nurse practitioner may write prescriptions, but a physician's signature is often required to validate the prescription.
