Medical-Surgical Nursing is a nursing speciality that focuses on the care of adult patients who are critically sick, have a variety of medical disorders or diseases, or are recuperating from surgery (perioperative care). "The diagnosis and treatment of human responses of individuals and groups to current or potential health problems," according to the definition of medical-surgical nursing. The purpose of medical-surgical nursing is to help a person or a group of people achieve, restore, or maintain their best health. Some consider medical-surgical work to be basic to all nursing practise. Medical-surgical nurses can work in a range of settings, including hospitals, homes, and outpatient clinics. The medical-surgical unit, it may be claimed, is the most significant department in an acute care hospital since it houses the most patients who can determine patient satisfaction levels.
