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?

Rationale: A. Tetracycline 200 mg PO: This prescription is incomplete because it does not specify the frequency or duration of administration, making it unclear how the medication should be given safely. B. Cimetidine PO twice daily: The prescription lacks the dosage strength in milligrams, which is essential for accurate administration and safe dosing. C. Digoxin 0.25 mg PO daily: This prescription includes the medication name, dosage, route, and frequency, providing all essential components needed for safe administration. D. Epoetin alfa 150 units/kg three times weekly: While it includes dose and frequency, it does not specify the route (subcutaneous or IV), which is required to complete the prescription safely.
