A nurse is reviewing medication prescriptions for a client. For which of the following entries on the client's medication administration record should the nurse request clarification?

A. Morphine 4 mg IV every 4 hr PRN for pain: This prescription is complete, specifying the medication, dose, route, frequency, and indication (pain). No clarification is needed before administration. B. Acetaminophen 500 mg every 4 hr PRN for fever: This prescription lacks a specified route, such as PO (by mouth) or IV. Without the route, the order is incomplete and could result in administration errors, requiring clarification from the provider. C. Simvastatin 40 mg PO at bedtime: This prescription is appropriate as simvastatin is typically administered orally at bedtime when cholesterol synthesis peaks. It includes all required components. D. Levothyroxine 100 mcg PO every morning: This order is correct and includes the appropriate dose, route, and timing. Levothyroxine is routinely administered orally in the morning on an empty stomach.
