A nurse is teaching a newly licensed nurse about transcribing prescriptions. Which of the following examples should the nurse include in the instructions?
Losartan 50.0 mg, PO, QD
Desmopressin .1 mL, intranasal, qd
Metformin 500 mg, 1 tablet, PO, daily
Zolpidem, 5 mg PO, HS
The Correct Answer is C
A. Losartan 50.0 mg, PO, QD: The use of decimal points with trailing zeros (50.0 mg) is discouraged to avoid potential errors. It should be written as 50 mg.
B. Desmopressin .1 mL, intranasal, qd: The abbreviation "qd" (quaque die) is not recommended due to potential misinterpretation. It should be written as "daily."
C. Metformin 500 mg, 1 tablet, PO, daily: This prescription is clear and correctly formatted, including the dosage, route, and frequency without ambiguous abbreviations.
D. Zolpidem, 5 mg PO, HS: The abbreviation "HS" (at bedtime) is acceptable, but clarity and standardization are preferred, and this option is less specific compared to C.

Correct Answer is ["A","C","D"]
Explanation
A. 2 mg: This is an acceptable abbreviation for the dosage of medication, as it uses standard metric units that are clear and precise.
B. MSO4: This abbreviation for morphine sulfate is not recommended due to the potential for confusion with magnesium sulfate. The use of "morphine sulfate" is preferred to avoid ambiguity.
C. 30 mL: This is an acceptable abbreviation for the volume of a liquid medication or fluid, using standard metric units.
D. bid: This abbreviation stands for "twice a day" and is generally acceptable in medical documentation, though "twice a day" is preferable to avoid errors.
E. Q.D.: This abbreviation for "every day" is not recommended because it can be confused with "QID" (four times a day). The use of "daily" is preferred for clarity.
Correct Answer is ["56"]
Explanation
To calculate the infusion rate, we'll use the following formula:
Infusion rate (gtt/min) = (Volume to be infused (mL) / Time (min)) Drop factor (gtt/mL)
First, calculate the total time in minutes:
- 3 hours 60 minutes/hour = 180 minutes
Then, calculate the volume per minute:
- 500 mL / 180 minutes = 2.78 mL/min
Finally, multiply the volume per minute by the drop factor:
- 2.78 mL/min 20 gtt/mL = 55.6 gtt/min
- Rounded off= 56gtt/min
