Often the specific amount of a drug to be administered must be calculated from a given dose in mg per kilogram of body weight. This assures that individuals who have very different body mass get the proper dose. If the proper dosage of a drug is 6.0 mg/kg of body weight, how many milligrams would a 210−lb individual need?
A 210-lb individual's weight equals 95.25 kg. As the proper dosage of a drug is 6.0 mg per one kilogram of body weight, the individual should take 571.5 mg of the drug.
