NursingNursing is a profession within the healthcare sector focused on the care of individuals, families, and communities so they may attain, maintain, or recover optimal health and quality of life. Nurses may be differentiated from other healthcare providers by their approach to patient care, training, and scope of practice. Nurses practice in many specialties with differing levels of prescription authority. Nurses comprise the largest component of most healthcare environments; but there is evidence of international shortages of qualified nurses.
Nurse practitionerA nurse practitioner (NP) is an advanced practice registered nurse and a type of mid-level practitioner. NPs are trained to assess patient needs, order and interpret diagnostic and laboratory tests, diagnose disease, formulate and prescribe medications and treatment plans. NP training covers basic disease prevention, coordination of care, and health promotion, but does not provide the depth of expertise needed to recognize more complex conditions. The scope of practice for a NP is defined by legal jurisdiction.
HospitalA hospital is a healthcare institution providing patient treatment with specialized health science and auxiliary healthcare staff and medical equipment. The best-known type of hospital is the general hospital, which typically has an emergency department to treat urgent health problems ranging from fire and accident victims to a sudden illness. A district hospital typically is the major health care facility in its region, with many beds for intensive care and additional beds for patients who need long-term care.
Perioperative nursingPerioperative nursing is a nursing specialty that works with patients who are having operative or other invasive procedures. Perioperative nurses work closely with surgeons, anaesthesiologists, nurse anaesthetists, surgical technologists, and nurse practitioners. They perform preoperative, intraoperative, and postoperative care primarily in the operating theatre. Also known as operating room nurses or OR nurses, perioperative nurses are registered nurses (RNs) who work in hospital surgical departments, day-surgery units (also called ambulatory surgery units), clinics, and physicians' offices.
