Nursing is one career that has more than one definition. Scholars have yet to agree on a single definition. Some say that nursing is love. In a way this is correct. A nurse cares for people who are sick in every way and sometimes all a person needs is love and someone to talk to. A scientific definition for nursing is "observes, assesses, and records symptoms, reactions, and progress of patients; administers medications; helps rehabilitate patients; instructs patients and family members in proper health care; and helps maintain a physical and emotional environment that promotes recovery". A nurse does not help only individuals, they also help families and groups achieve health and prevent disease.
