Nursing is a health care profession that "integrates the art and science of caring and focuses on the protection, promotion, and optimization of health and human functioning; prevention of illness and injury; facilitation of healing; and alleviation of suffering through compassionate presence".[1] Nurses practice in many specialties with varying levels of certification and responsibility. Nurses comprise the largest component of most healthcare environments.[2][3] There are shortages of qualified nurses in many countries.[4]
Nurses develop a plan of care, working collaboratively with physicians, therapists, patients, patients' families, and other team members that focuses on treating illness to improve quality of life.
In the United Kingdom and the United States, clinical nurse specialists and nurse practitioners diagnose health problems and prescribe medications and other therapies, depending on regulations that vary by state.[5] Nurses may help coordinate care performed by other providers or act independently as nursing professionals. In addition to providing care and support, nurses educate the public and promote health and wellness.[6]
In the U.S., nurse practitioners are nurses with a graduate degree in advanced practice nursing, and are permitted to prescribe medications. They practice independently in a variety of settings in more than half of the United States. In the postwar period, nurse education has diversified, awarding advanced and specialized credentials, and many traditional regulations and roles are changing.[7][8]
