A nurse is preparing to enter a prescription from a provider. Which of the following formats should the nurse use?
Metformin 500mg one tablet q1d
Metformin 500mg one tablet PO daily
Metformin 500mg one tablet q.d.
Metformin 500mg one tablet QD
The Correct Answer is B
A. "q1d" is not a standard abbreviation and can cause confusion.
B. "PO daily" is clear and follows the standard practice for medication orders, indicating the route (by mouth) and frequency (daily).
C. "q.d." can be misinterpreted due to its similarity to other abbreviations and is not recommended by the Joint Commission.
D. "QD" is also discouraged due to potential misinterpretation; "daily" is preferred for clarity.
