Clients at risk include those who are very young or very old and those who have cardiovascular disease, hypothyroidism, diabetes, or alcoholism. Also at risk are those who take medications that decrease the body's ability to lose heat (e.g., phenothiazines, anticholinergics, diuretics, am-phetamines, and beta-adrenergic receptor antagonists) and those who exercise or work strenu-ously (e.g., athletes, construction workers, and farmers). While all the options represent risk fac-tors, the degree of exercise, medical history, and age are greatest for the 16-year-old client with diabetes.
