Henderson, Virginia [1897–1996] , a nursing theorist who introduced a holistic approach to the profession in 1966. The theory is based on the concepts that the body and mind are inseparable, no two individuals are alike, and the role of nursing is independent of the functions of the physician. The Henderson theory proposes that 14 components of basic nursing care contribute to the health of a patient. They relate to (1) breathing, (2) eating and drinking, (3) elimination, (4) movement and posture, (5) sleep and rest, (6) clothing, (7) maintenance of body temperature, (8) cleaning and grooming of the body, (9) avoidance of environmental dangers and injury, (10) communication, (11) worship, (12) work, (13) play and recreation, and (14) learning and discovery.
