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 10 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:
The provider ordered 15 g/day of niacinamide. 15g=15,000mg
Tablet strength: Each tablet contains 500 mg. 15,000mg÷500mg=30tablets/day
Dosing schedule: The order is for a daily dose, divided evenly across the day. If given every 8 hours (3 doses/day): 30tablets÷3doses=10 tablets/dose

Correct Answer is A
Explanation
Robitussin DM contains 100 mg of guaifenesin per 1 teaspoon. One teaspoon is equivalent to 5 milliliters, so 100 mg is present in 5 mL. Therefore, 10 mL of Robitussin DM contains 2 times the amount of guaifenesin in 1 teaspoon or 200 mg.
Correct Answer is B
Explanation
The amount of solution the nurse should withdraw from the vial can be calculated using the following formula:
Amount of solution = Amount of medication needed / Concentration of medication in the solution.
In this case, the amount of medication needed is 17.1 mg and the concentration of medication in the solution is 3 mg/mL. Substituting these values into the formula, we get:
Amount of solution = 17.1 mg / 3 mg/mL = 5.7 mL
Therefore, the answer is B. The nurse should withdraw 5.7 mL of solution from the vial.
