Calculation
A nurse is caring for an infant who weighs 12 lb and is prescribed cefuroxime sodium 15mg/kg PO every 12 hr. Available is cefuroxime sodium oral solution 125mg/5mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
mL
Explanation & Rationale
Convert weight to kilograms: 12 lb×0.45359237=5.4431 kg. Dose = 15 mg/kg×5.4431 kg=81.65 mg. Concentration = 125 mg/5 mL=25 mg/mL. Volume = 81.65 mg÷25 mg/mL=3.2659 mL rounded to the nearest tenth = 3.3 mL.
