Correct Answer: D
Rationale: The prescription indicates a dosage of Xanax 5 mg tablets, which is not commercially available; the highest dosage form is 2 mg. Therefore, clarification is necessary to ensure the patient receives the correct medication.
Option A is incorrect because Xanax can be prescribed b.i.d. as needed. Option B is not a reason for clarification since refills are not always required for prn prescriptions. Option C is also misleading; while maximum daily doses are important, the lack of a specified maximum is not uncommon for prn medications and does not necessitate contacting the prescriber in this case.
