Question 1 of 5
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.
Correct Answer: A
Rationale:
To calculate the dose of diphenhydramine for the child, first, we need to determine the total dose based on the weight. The child weighs 20 kg, so the total dose would be 5 mg/kg x 20 kg = 100 mg. Next, we need to convert this dose to milliliters based on the concentration. Since the medication is supplied as 12.5 mg/5 ml, we divide the total dose by the concentration: 100 mg / 12.5 mg/5 ml = 40 ml. However, the question asks for the dose in milliliters for one dose, so we need to divide this by 4 to find the dose for one dose: 40 ml / 4 = 10 ml.
Therefore, the correct answer is A: 8 ml.
Choices B, C, and D are incorrect as they do not match the calculated dose based on the given information.
