The health care provider has prescribed diphenhydramine (Benadryl) 5 mg/kg/dose for a child with urticaria weighing 44 lbs. (20 kg). Assume this is a safe dose. The medication is supplied as 12.5 mg/5 ml. How many milliliters will the nurse administer to the child for one dose? Record your answer using a whole number.
The Correct Answer is ["8"]
To calculate the dosage of diphenhydramine (Benadryl) for the child, we first determine the total milligrams needed per dose by multiplying the child's weight in kilograms by the prescribed milligrams per kilogram. The child weighs 20 kg, so the calculation is 20 kg * 5 mg/kg, which equals 100 mg per dose. The medication is supplied at a concentration of 12.5 mg per 5 ml. To find out how many milliliters are needed to provide 100 mg, we set up a proportion: 12.5 mg/5 ml = 100 mg/x ml. Solving for x gives us x = (100 mg * 5 ml) / 12.5 mg, which equals 40 ml. Therefore, the nurse will administer 40 milliliters of the medication for one dose.
