Determine drug dosage by a patient's weight. For each kilogram of a person's weight, 20 milligrams of a drug is to be given. What dosage should be given to a person who weighs 200 pounds? (Use 1 pound = 0.45 kg)

Answer 1

To determine the dosage of the drug based on a person's weight, we need to convert their weight from pounds to kilograms.

Given:
Weight = 200 pounds
1 pound = 0.45 kg

Weight in kilograms = 200 pounds * (0.45 kg/1 pound) = 90 kg

Now that we have the weight in kilograms, we can calculate the drug dosage.

Dosage = 20 milligrams per kilogram * 90 kilograms = 1800 milligrams

Therefore, a person who weighs 200 pounds should be given a dosage of 1800 milligrams of the drug.
