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.

Correct Answer is D
Explanation
A. 1 pint is actually approximately 473 mL, not 960 mL, making this conversion incorrect. Providing accurate conversion information is essential for ensuring proper medication dosing and patient safety.
B. 1 teaspoon (tsp) is equal to 5 mL, not 10 mL. Incorrect conversions can lead to dosing errors, potentially resulting in underdosing or overdosing.
C. 2 tablespoons (Tbsp) is actually equal to 30 mL, not 15 mL. Accurate conversions are crucial for patient safety, particularly in pediatric and elderly populations where precise dosing is critical.
D. 1 cup is correctly equal to 240 mL, making this conversion accurate. Correct conversions ensure that patients receive the appropriate volume of medication or fluid.
Correct Answer is C
Explanation
Intramuscular administration provides relatively quick absorption but is slower than intravenous.
B. Enteral (oral) administration has the slowest absorption rate due to the process of digestion and first-pass metabolism in the liver.
C. Intravenous administration delivers the medication directly into the bloodstream, resulting in the fastest absorption and onset of action.
D. Topical administration is typically used for localized treatment and has a slower absorption rate compared to intravenous.
