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.

Correct Answer is D

Explanation

To calculate the time it will take to finish the infusion, we can use the formula:

Time = Volume / Rate

Plugging in the given values, we get: Time = 1.5 L / 75 mL/hr

Converting 1.5 L to mL, we get:

Time = 1500 mL / 75 mL/hr Simplifying, we get:

Time = 20 hours

Therefore, it will take 20 hours to finish the infusion at the current rate.

A. 1 mL B. 1.1 mL C. 3.6 mL D. 11 mL

Correct Answer is B

Explanation

We can use proportion to calculate the volume of Primaxin to administer:. 275 mg is to X mL as 500 mg is to 2 mL.

275/X = 500/2.

Cross-multiplying, we get:. 500X = 275 x 2.

X = (275 x 2)/500. X = 1.1 mL.

Therefore, the nurse should administer 1.1 mL of Primaxin to the patient, rounded to the nearest tenth.
