Question

Suppose a pencillin dose of 9000 units per kilogram of body weight taken every 6 hours is prescribed for treatment of a bacterial infection, For penicillin 400,000 units is equal to 250mg. Express the dose in milligrams per kilogram of body weight

Answer 1

5.625 mg

Explanation:

400,000 units = 250 mg

Divide both sides of the equation above by 400,000 units and switch sides.

(250 mg)/(400,000 units) = 1

9000 units × (250 mg)/(400,000 units) = 5.625 mg
