A nurse is preparing to transcribe a prescription for a client that reads "ondansetron 8 mg by mouth every 12 hr PRN." Which of the following parts of the prescription should the nurse clarify with the provider?

A. Reason: The prescription does not specify the indication for ondansetron, such as nausea or vomiting. Clarifying the reason ensures the medication is appropriate for the client’s condition and supports safe and effective administration. B. Dose: The dose of 8 mg is within the recommended range for adults and does not require clarification. It is appropriate for PRN administration for nausea or vomiting. C. Route: The route “by mouth” (PO) is clearly specified and appropriate for ondansetron tablets. No clarification is needed unless the client cannot take oral medications. D. Frequency: The frequency “every 12 hr PRN” is clearly indicated, specifying that the medication is to be taken as needed up to every 12 hours. This does not require clarification.
