A registered professional nurse (RN) is a licensed health care professional who helps patients to achieve optimal health and prevent disease or injury. RNs provide compassionate care that is respectful of each patient's values and wishes. They coordinate and supervise care provided by other personnel, such as licensed practical nurses or home health aides. RNs provide health teaching to patients, families, other care providers and the public. They participate in health research and in making health care policies. RNs may work independently, in collaboration with other health care personnel or under clinical supervision (i.e., from a physician or nurse practitioner). They work in a variety of settings, such as hospitals, nursing homes, community residences, mental health facilities, clinics, private practices, surgery centers, county health departments, correctional facilities, work places, camps, schools and private homes.
