A 17-kg child has been prescribed cefaclor 340 mg orally every 12 hours. The recommended dosage is 10 to 20 mg/kg/day. After calculating the total daily dose, the nurse finds it exceeds the recommended range. What is the nurse's most appropriate action?

Hold the medication and wait for the next scheduled dose without further action.

Administer the medication as prescribed since the dose matches the prescription.

Double-check the child's weight and administer half the prescribed dose to ensure safety.

Notify the prescriber to review and potentially adjust the dosage to fall within the safe range.
