Question 1 of 5
A nurse is preparing to administer acetaminophen 10/mg/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? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: First, convert the child's weight from pounds to kilograms: 22 lb ÷ 2.2 = 10 kg. Calculate the dose: 10 kg × 10 mg/kg = 100 mg. Next, calculate how many mL of acetaminophen liquid (160 mg/5 mL) is needed for 100 mg: 100mg ÷ 160mg/5ml = 100 × 5/160 = 3.125ml. Rounded to the nearest tenth, administer 3.1 mL (since the medication is typically measured in tenths).
