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?

A. Holding the medication without notifying the provider puts the child at continued risk of receiving an unsafe dose later. The nurse must take action by contacting the prescriber. B. Even if the prescription is written that way, nurses are legally responsible for identifying unsafe doses—especially in pediatrics where dosing is weight-based. C. Nurses cannot independently change the dose. Verifying weight is appropriate, but altering the dose without provider direction is unsafe and outside scope. D. When a dose exceeds the safe mg/kg/day range, the nurse must contact the provider, report the calculated mg/kg/day amount, and request clarification or a new order. This is the safest and most appropriate action.
