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

Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mg/h) x Volume (mL) / Concentration (mg)
Plugging in the given values, we get:
Infusion rate (mL/h) = 3 mg/h x 500 mL / 50 mg
Simplifying, we get:
Infusion rate (mL/h) = 30 mL/h
Correct Answer is ["7672.32"]
Explanation
To calculate the amount of heparin, we need to use the formula:
Amount (units) = Dose (units/kg) x Weight (kg)
First, we need to convert the weight from pounds to kilograms by multiplying by 0.454. In this case, 211.2 pounds is equivalent to 95.904 kg.
Plugging inthe given values, we get:
Amount (units) = 80 units/kg x 95.904 kg
Simplifying, we get:
Amount (units) = 7,672.32 units
