A client is receiving an intravenous (IV) infusion of nitroglycerin 100 mg in 500 mL of D5W at 6 mL/hour. How many mg/minute of nitroglycerin is infusing?
(Enter numerical value only.)
The Correct Answer is ["0.002"]
To calculate the dose rate, we need to use the formula:
Dose rate (mg/min) = Infusion rate (mL/h) x Concentration (mg/mL) / Time (min)
First, we need to calculate the concentration of nitroglycerin in the solution by dividing the total amount by the total volume. In this case, it is 100 mg / 500 mL.
Plugging in the given values, we get:
Dose rate (mg/min) = 6 mL/h x 100 mg / 500 mL / 60 min
Simplifying, we get:
Dose rate (mg/min) = 0.002 mg/min

Correct Answer is ["3.5"]
Explanation
To calculate the total volume of diluted medication, we need to use the formula:
Total volume (mL) = Drug volume (mL) + Diluent volume (mL)
First, we need to calculate the drug volume by dividing the dose by the concentration. In this case, 1 mg of hydromorphone is equivalent to 0.5 mL of hydromorphone injection.
Plugging in the given values, we get:
Total volume (mL) = 0.5 mL + 3 mL
Simplifying, we get:
Total volume (mL) = 3.5 mL
Correct Answer is ["4.494"]
Explanation
To calculate the infusion rate, we need to use the same formula as in Text 1, but with a different volume of solution.
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mcg/min x 74.91 kg x 150 mL / 50,000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 4.494 mL/h
