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

Answer and Explanation

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.

Explanation

To determine the mL per dose of heparin, we can use the following formula:

mL per dose = (total units needed) / (concentration of heparin in units/mL). Substituting the values given in the

Question :.

mL per dose = 10,000 units / 20,000 units/mL = 0.5 mL per dose.

Therefore, the client should receive 0.5 mL per dose of heparin from the vial containing a concentration of 20,000 units/mL.

A. 2 mL B. 3 mL C. 4 mL D. 5 mL
