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)
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.
To determine the drug dosage, we need to convert the weight of the person from pounds to kilograms, then multiply by the dosage per kilogram.
Given that 1 pound is equal to 0.45 kilograms, we can calculate the weight of the person in kilograms by multiplying their weight in pounds by 0.45:
Weight in kilograms = 200 pounds * 0.45 kg/pound
Weight in kilograms = 90 kg
Now that we have the weight of the person in kilograms, we can calculate the drug dosage by multiplying the weight by the dosage per kilogram:
Drug dosage = 90 kg * 20 mg/kg
Drug dosage = 1800 mg
Therefore, a person who weighs 200 pounds should be given a drug dosage of 1800 milligrams.
