Question

A child's pain relief elixir contains 80 mg acetaminophen per.50 teaspoon. The dosage recommended for a child who weighs between 24 and 35 lbs is 1.5 teaspoons. What is the range of acetaminophen dosages expressed in mg aceteminophen/kg of body weight for child who weigh between 24 and 35 lbs?

Answer 1

80 mg/0.5 teaspoon (you need to stick that 0 before the .5; otherwise the . sometimes gets overlooked) = 160 mg/teaspoon. So how much is that per 1.5 teaspoons?
160 mg/teaspoon x 1.5 teaspoons = 240 mg acetaminophen.
Now you need to convert 24 lbs and 35 lbs to kg. 2.2 lbs = 1 kg.
The range then, per kg, will be 240 mg/??kg and 240 mg/?? kg where ??kg is the 24 and 35 lb numbers for kg.
