Final answer:
The dosage for a child can be calculated based on their body surface area (BSA). The formula for calculating the child's dosage is (Adult dosage) x (Child's BSA) / (Average adult BSA).
Step-by-step explanation:
The adult dosage of penicillin V potassium, USP, is 250 mg every 6 to 8 hours. However, the dosage for a child is usually calculated based on their body surface area (BSA). To calculate the dosage for a child, you can use the formula:
Dosage for child = (Adult dosage) x (Child's BSA) / (Average adult BSA)
Therefore, the dosage for the child who is 24 inches tall and weighs 35 pounds (with a BSA of 0.56) would be:
Dosage for child = (250 mg) x (0.56) / (1.73 m2)
Using the conversion factor 1m = 39.37 inches, we can calculate the dosage for the child.
