School-age child who weighs 55 lb
Question 1 of 5
A nurse is planning to administer diphenhydramine 1.25 mg/kg IV to a school-age child who weighs 55 lb. Available is diphenhydramine 50 mg/mL. How many mL should the nurse administer?
Correct Answer: B
Rationale:
To calculate the dose of diphenhydramine for the child, first convert the weight from pounds to kg: 55 lb ÷ 2.2 = 25 kg.
Then calculate the dose: 1.25 mg/kg x 25 kg = 31.25 mg. Next, determine how many mL are needed: 31.25 mg ÷ 50 mg/mL = 0.625 mL. Since we need to round to the nearest tenth, the correct answer is 0.6 mL (choice
B). Other choices are incorrect due to incorrect calculations or rounding errors.
Choice A is too low, C is too high, and D is also too high.
