Question 17 :
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.)
Correct Answer: ["0.002 mg\/min"]
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
