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?
Correct answer
B

Step 1: 22 lb ├â┬À 2.2 lb/kg = 10 kg. Step 2: 10 mg/kg ├âÔÇö 10 kg = 100 mg. Step 3: 100 mg ├â┬À (160 mg/5 mL) = 100 mg ├âÔÇö (5 mL/160 mg) = 3.125 mL, rounded to 3.1 mL.
