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 4 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: Each tablet contains 500 mg, so 4 tablets provide 2000 mg (2 g). Administering 4 tablets every 8 hours (three times daily) totals 12 tablets/day, which equals 15,000 mg (15 g/day) and fulfills the prescription accurately.

Correct Answer is D
Explanation
To calculate the amount of drug per minute, divide the total dose by the infusion time in minutes:
5 mg ÷ 2 minutes = 2.5 mg/minute
The patient should receive 2.5 mg of Lopressor per minute for 2 minutes to get a total dose of 5 mg.
