Quizplus · Accepted Answer

The correct dosage is calculated based on the concentration of the medication in the solution. Given that the concentration is 20 mg per 5 mL, for a 40 mg dose, you would need 10 mL of the solution (since 40 mg is twice the amount of the 20 mg, you need twice the volume of 5 mL, which is 10 mL).
