Question

Betty Neuman's theory defines health as more energy generated than expended,and illness,possibly even death,as more energy expended than generated.The World Health Organization defines health as "a state of complete physical,mental,and social well-being and not merely the absence of disease or infirmity." That definition does not involve energy expenditure,so is irrelevant to the patient's nursing diagnosis.Jean Watson's definition involves a high level of overall physical,mental,and social functioning; a general adaptive-maintenance level of daily functioning; and the absence of illness,but does not address energy expenditure.Myers,Sweeney,and Witmer defined wellness as a way of life oriented toward optimal health and well-being in which body,mind,and spirit are integrated; with no mention of energy balance,this theory is not relevant to the nursing diagnosis.
