Calculation
A nurse is preparing to administer amoxicillin 30 mg/kg/day divided doses every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension. How many mL should the nurse administer every 12 hr? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
mL
Explanation & Rationale
Convert 33 lb to kg: 33 ÷ 2.2 = 15 kg 30 mg/kg/day × 15 kg = 450 mg/day Every 12 hr → 450 ÷ 2 = 225 mg/dose 200 mg in 5 mL → 225 mg = (225 × 5) ÷ 200 = 5.625 mL Round to nearest tenth = 5.6 mL
