Correct Answer is A

Explanation

A. Dose: It is critical to confirm the specific dosage of buspirone (e.g., milligrams per tablet) before administering the medication. The correct dosage ensures that the client receives an effective and safe amount of the drug, optimizing treatment outcomes. Administering an incorrect dose could lead to insufficient therapeutic effects or increased risk of side effects, which can be particularly important in medications affecting anxiety and mood.

B. Medication: The medication is already clearly specified as buspirone in the prescription, so there is no need to add or clarify this component. The clarity of the medication name is crucial for safe administration.
C. Route: The prescription explicitly states the route as "PO" (by mouth), meaning no further clarification or addition is necessary. Clear documentation of the route is vital for ensuring the medication is taken as intended, minimizing the risk of administration errors.

D. Frequency: The frequency of "every 12 hr" is clearly indicated, meaning it does not require any modification. Proper frequency ensures that the medication maintains its effectiveness, and having it specified helps prevent potential overdosing or subtherapeutic dosing.
