A nurse is preparing to administer ibuprofen 10 mg/kg PO to a child. The child weighs 55 lb. Available is ibuprofen 100 mg/5 mL solution. 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.)

Convert pounds to kilograms 1 lb is approximately 0.453592 kg 55 lb * 0.453592 kg/lb = 24.94756 kg Dose = weight in kg * prescribed dose Dose = 24.94756 kg * 10 mg/kg = 249.4756 mg The ibuprofen solution is 100 mg/5 mL To find the volume for 249.4756 mg: (249.4756 mg / 100 mg) * 5 mL = 12.47378 mL 12.47378 mL ≈ 12.5 mL Therefore, the nurse should administer 12.5 mL of ibuprofen.
