Professional Nurses–also known as Registered Nurses (RN)– are a crucial component of the Healthcare Delivery System. Registered Nursing requires a large skillset consisting of information and experiential knowledge employed to assess, develop, and implement care plans to promote health. This often includes matters of disease prevention and coping with illness in that nurses observe patients to assess their condition by recording symptoms, reactions, and progress. This information then provides the basis for care planning and intervention. Registered Nurses are health educators and patient advocates.
