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
B
Rationale
Weight = 22 lb / 2.205 = 9.98 kg. Dose = 10 mg/kg ├âÔÇö 9.98 = 99.8 mg. Volume = 99.8 mg / (160 mg/5 mL) = 3.12 mL, rounded to 3.1 mL.
