Textbook Question

Administration of digitalis, a drug used to control atrial fibrilla-tion in heart patients, must be carefully controlled because even a modest overdose can be fatal. To take differences between patients into account, drug dosages are prescribed in terms of mg/kg body weight. Thus, a child and an adult differ greatly in weight, but both receive the same dosage per kilogram of body weight. At a dosage of 20 mg/kg body weight, how many mil-ligrams of digitalis should a 160 lb patient receive?
