A certain drug dosage calls for 21 mg per kg per day and is divided into two doses (1 every 12 hours). If a person weighs 181 pounds, how much of the drug should they get each dosage?

Answer 1

The person weighing 181 pounds should get 862.05 mg of drugs for each dose.

= 82.1 x 10.5

= 862.05 mg of drugs can be taken

The person weighing 181 pounds should get 862.05 mg of drugs for each dose.
