A primary healthcare provider prescribes 15 g/day niacinamide to a client. Upon checking the medication bottle, the nurse finds that each tablet contains 500 mg and has a score mark. How should the nurse administer the prescribed dose?
Administer 1 tablet of medication once daily.
Administer 2 tablets of medication three times daily.
Administer half a tablet of medication once daily.
Administer 10 tablets of medication every 8 hours.
None
None
The Correct Answer is D
Choice A: One tablet contains 500 mg, which is far below the prescribed dose of 15 g/day. Administering one tablet daily would only provide 500 mg/day, which is insufficient.
Choice B: Each dose of 2 tablets provides 1000 mg (1 g), and giving this dose three times daily totals 3000 mg (3 g/day). This is significantly less than the required 15 g/day.
Choice C: Half a tablet would provide 250 mg/day, which is far below the prescribed dose of 15 g/day. This is inadequate and does not meet the prescription requirements.
Choice D:
The provider ordered 15 g/day of niacinamide. 15g=15,000mg
Tablet strength: Each tablet contains 500 mg. 15,000mg÷500mg=30tablets/day
Dosing schedule: The order is for a daily dose, divided evenly across the day. If given every 8 hours (3 doses/day): 30tablets÷3doses=10 tablets/dose

Correct Answer is C
Explanation
To calculate the total infusion time, we need to divide the total volume to be infused by the infusion rate:.
Total infusion time = Total volume to be infused / Infusion rate.
In this case, the total volume to be infused is 1000 mL, and the infusion rate is 250 mL/hr:.
Total infusion time = 1000 mL / 250 mL/hr. Total infusion time = 4 hours.
Therefore, the infusion will be completed 4 hours after it was started at 09:20, which would be at 13:20.
Correct Answer is C
Explanation
The Tylenol 3 medication contains codeine 30 mg and acetaminophen (APAP) 300 mg per tablet.
The physician has ordered Tylenol 3 30 mg every 4-6 hours as needed for pain. Therefore, the nurse should administer 1 tablet (containing 30 mg of codeine and 300 mg of APAP) every 4-6 hours as needed for pain..
It is important to note that the maximum daily dose of acetaminophen is 4,000 mg. Therefore, the nurse should monitor the total daily dose of acetaminophen the patient receives from all sources to ensure it does not exceed 4,000 mg.
