Nurses are professionals dealing with the field of nursing, meaning taking care of the health of people who are physically unwell. Their task involves treating emergencies, ensuring recovery and safety, maintaining health, and many more. Furthermore, together with different individuals like physicians, they can be involved in medical research and do task necessary for promoting health care.
Sometimes they are interdependent with other health care professionals and individuals like therapists, physicians, and other members of the team, together with the patient and the family of the patient in developing a plan of care. They can also act as mediators between experts like dietitians, therapists and medical practitioners in coordinating with the patient. Independent duties are also practiced by nurses. For example, advanced practice nurses in the United States and some in the United Kingdom provide diagnosis, therapies and prescriptions.
The United States Depart of Labor describes the registered nurses as the ones whose work deals with prevention of diseases, helping patients to deal with stress, and the promotion of health, educating people about health, developing and managing nursing care plans, helping improvement or maintenance of health, and instructing patients and their families. More particularly in direct patient care, they are to assess, observe, and identify symptoms.
Sometimes different from country to country; the structure of nursing is characterized according to levels of education, skills and responsibilities. In other words, it may be professional nursing or task-based nursing. Educational requirement for practitioners also differ, that is, in some countries like Eastern Europe only one year to one and a half years of training is needed upon graduation from high school. Meanwhile, a bachelor's degree is one minimum requirement in other countries.
Advancement both in nursing art and nursing science demands for nurses of higher level of education, specifically of doctoral degrees like Doctor of Nursing Science (DNSc) and Doctor of Nursing Practice (DNP). They specialize more in clinical nursing, nursing research, and nursing education.
