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
The Joint Commission has a list of approved medical abbreviations that should be used to prevent miscommunication and errors in healthcare settings.
Out of the abbreviations listed in the
Question , only "IV" (for intravenous) is on the Joint Commission's list of approved abbreviations.
"IU" (for international unit) is not on the list because it can be misinterpreted as "IV" (intravenous) or "10" (the Roman numeral for 10).
"QD" (for once daily) is also not on the list because it can be misinterpreted as "QID" (four times daily) or "QOD" (every other day).
"QOD" (for every other day) is also not on the list because it can be misinterpreted as "QD" (once daily) or "QID" (four times daily).
Therefore, the correct answer is A. IV.
Correct Answer is C
Explanation
We need to calculate the patient's BSA using one of the available formulas. The most widely used formula is the Du Bois formula, which is:.
BSA = 0.007184 × W^0.425 × H^0.725.
where W is weight in kg and H is height in cm.. Plugging in the patient's weight and height, we get:. BSA = 0.007184 × 94.5^0.425 × 185^0.725
BSA = 2.15 m².
Now, we can use the physician's order to find the daily dose and the total dose of Platinol for this patient. The daily dose is:.
Daily dose = 20 mg/m²/day × BSA Daily dose = 20 mg/m²/day × 2.15 m² Daily dose = 43 mg/day.
The total dose for 5 days is:.
Total dose = Daily dose × Number of days Total dose = 43 mg/day × 5 days
Total dose = 215 mg.
Therefore, the patient's dose of Platinol would be 215 mg in total, or 43 mg per day for 5 days.
