Question 1 of 5

A nurse is preparing to administer acetaminophen 10mg/kg PO to a preschool child for fever. The child weighs 22 lb. Available is acetaminophen liquid 160 mg/5 mL. How many mL should the nurse administer?

Correct Answer: A

Rationale: The child weighs 22 lb, which is approximately 10 kg (since 1 kg is approximately 2.2 lb). The prescribed dose of acetaminophen is 10 mg/kg.
Step 1 is: Calculate the total dose of acetaminophen for the child. This is done by multiplying the child's weight in kg by the prescribed dose in mg/kg. 10 kg×10 mg/kg=100 mg The available acetaminophen liquid is 160 mg/5 mL.
Step 2 is: Calculate the volume of acetaminophen liquid to administer. This is done by setting up a proportion with the total dose of acetaminophen and the concentration of the available liquid. x mL100 mg=5 mL160 mg Solving for x gives: x=160 mg mg×5 mL=3.125 mL
Therefore, the nurse should administer approximately 3.125 mL of the acetaminophen liquid.
