A nurse is a person who is trained to give care to people who are sick or injured. Nurses work with [doctors] and other health care workers to make patients well and to keep them fit and healthy. Nurses also help with end-of-life needs and assist other family members with grieving.
Nursing is a profession, like a doctor, but training for a nurse is different in how long a person must train and what kind of training they need. In some places, nurses may train for three to five years or more before they get a license as a nurse.
