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 C

No explanation

A. 9 hr and 15 min B. 9 hr and 24 min C. 9 hr and 30 min D. 9 hr and 40 min

Correct Answer is B

Explanation

We can use the following formula to calculate the infusion time:

Infusion time (in hours) = Remaining volume (in mL) / Infusion rate (in mL/hr)

First, let's convert the current time to minutes since we will be calculating the infusion time in minutes as well:

19:30 = 19 hours x 60 minutes/hour + 30 minutes = 1170 minutes Now we can substitute the given values into the formula:

Infusion time (in hours) = 376 mL / 40 mL/hr Infusion time (in hours) = 9.4 hours

To convert this to hours and minutes, we can separate the integer and decimal parts of the answer:

9 hours (integer part) and 0.4 hours x 60 minutes/hour = 24 minutes (decimal part)

Therefore, the infusion time is 9 hours and 24 minutes, and the infusion will finish at approximately 04:54 (19:30 + 9 hours and 24 minutes).
