A quality control nurse is reviewing medication prescriptions for a group of clients. Which of the following medication prescriptions should the nurse identify as being complete?

A. Cimetidine PO twice daily is incomplete because it does not specify the dose. B. Tetracycline 200 mg PO is incomplete because it does not specify frequency (e.g., daily, every 6 hours). C. A complete medication order includes: Medication name (Digoxin), dose (0.25 mg), route (PO), frequency (daily). This prescription meets all requirements. D. Epoetin alfa 150 units/kg three times weekly is incomplete because it does not specify the route (e.g., subcutaneous or IV).
