Pediatric Drug Dosage Calculation

Hello! Today we are calculating the pediatric dosage of a drug based on body surface area, often abbreviated as B S A.

First, let's identify what we are given. The average adult dose is twenty milligrams. And the child's body surface area is point eight seven square meters.

To solve this, we use the standard body surface area formula for pediatric dosing. This formula relates the child's dose to the adult dose by using the average adult body surface area, which is internationally recognized as approximately one point seven three square meters.

Now, let's substitute our known values into this equation. We'll put point eight seven in the numerator for the child's body surface area and twenty milligrams for the adult dose.
