Question

A 2-year-old child who weighs 30 lb needs to take a medication that is given to an adult as 250 mg bid. How many milligrams will he need to take if the recommended dose is 15 mg/kg/dose?

Answer 1

The child would need approximately 204.5 mg per dose.

Step-by-step explanation:

To calculate the dosage for the 2-year-old child who weighs 30 lb, we first need to convert the weight from pounds to kilograms, as the recommended medication dose is given in mg/kg/dose.

There are 2.2 lb in 1 kg, hence:

30 lb ÷ 2.2 lb/kg = 13.636 kg (rounded to three decimal places)

Now, using the recommended dose of 15 mg/kg/dose:

13.636 kg × 15 mg/kg

= 204.545 mg/dose

The child would need to take approximately 204.5 mg per dose, considering dose rounding guidelines in pediatric medicine which may vary by institution.
