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.)

Step 1: Convert the infant’s weight from pounds to kilograms Weight in kg = 12 ÷ 2.2 ≈ 5.45 kg Step 2: Calculate the dose in mg Dose = 15 mg/kg × 5.45 kg ≈ 81.75 mg Step 3: Determine the volume to administer using the concentration Available = 125 mg / 5 mL Volume (mL) = (Desired dose ÷ Concentration per mL) × 5 Volume = (81.75 ÷ 125) × 5 ≈ 3.27 mL Step 4: Round to the nearest tenth Volume ≈ 3.3 mL Final Answer: 3.3 mL
