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 C
Explanation
The correct answer is choice C, 3 tablets. To calculate the number of tablets, divide the ordered dose by the available dose:
75 mg ÷ 25 mg = 3
The nurse should administer 3 tablets of Coumadin 25 mg to the patient to give a total dose of 75 mg.
Correct Answer is B
Explanation
The correct answer is choice B. 31. To find the number of bottles required, use the formula: (dose x frequency x duration) / (bottle size x bottle concentration). In this case, (4 mg/kg x 43 kg x 3 times/day x 6 days) / (100 mg/bottle) = 30.96 bottles. Round up to the nearest whole number to get 31 bottles.
