Nursing is the largest health care profession in the United States and the demand for nurses continues to grow. The field has many specialties--from geriatrics and palliative nursing to working in the NICU with newborns. In hospitals and other health care facilities, they follow strict protocols when handling patient care and coordinating with staff members and doctors. Nurses are often the first health care professional to see the patient. They help prepare patients for surgeries and treatments, administer medications, and assist surgeons and doctors with procedures and daily tasks. Some nurses also share information about how to live a healthy lifestyle and make educated choices for your medical care.
