Question 5 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 160mg/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: C
Rationale: Weight = 22 lb × 0.453592 = 9.98 kg. Dose = 10 mg/kg × 9.98 kg = 99.8 mg. Volume = 99.8 mg × (5 mL / 160 mg) = 3.12 mL, rounded to 3.1 mL.
