Question

7. An 18-month-old and weighing 32 pounds needs streptomycin sulfate. This drug is administered to
adults as 1 gm in a daily IM injection. What is the appropriate dosage for the infant? Use Young's Rule.

Expert Solution

Step 1

Age of the infant = 18 month

1 year = 12 month

Age of the infant in years = 18 month × (1 year/12 month) = 1.5 years
