A nurse will administer Nubain (nalbuphine) 0.3 mg/kg IV over 10 minutes. The Nubain is available in 10 mg/mL. The patient weighs 148 lb.
How many milliliters per minute of Nubain should the nurse administer?
0.2 mL/min
0.4 mL/min
1 mL/min
2 mL/min
2 mL/min
The Correct Answer is A
The patient is ordered to receive 0.3 mg/kg of Nubain IV over 10 minutes. The patient weighs 148 lb, which is equivalent to 67.3 kg. To calculate the total amount of Nubain the patient should receive, multiply the weight by the dosage:
67.3 kg x 0.3 mg/kg = 20.19 mg
The Nubain is available in 10 mg/mL, which means there is 10 mg of Nubain in 1 mL of solution. To calculate how many milliliters of Nubain the patient should receive, divide the total amount of Nubain by the concentration:
20.19 mg / 10 mg per mL = 2.019 mL
To calculate how many milliliters per minute the nurse should administer, divide the total volume of Nubain by the infusion time:
2.019 mL / 10 minutes = 0.2019 mL per minute
Rounding to one decimal place, the nurse should administer 0.2 mL of Nubain per minute to the patient.

Correct Answer is A
Explanation
First, we need to convert the weight of the child from pounds to kilograms:. 99 lb / 2.2046 = 44.91 kg (rounded to two decimal places).
Next, we can calculate the dose of carmustine:. 25 mg/kg x 44.91 kg = 1,122.75 mg.
We should always check our calculation and verify that the dose is appropriate and safe for the child. In this case, the dose of 1,122.75 mg seems reasonable for a child with Hodgkin disease..
Since the medication is prescribed daily, the nurse should administer the calculated dose of 1,122.75 mg of carmustine to the child every day.
Correct Answer is D
Explanation
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
