A client who weighs 176 pounds receives a prescription for dobutamine 2 mcg/kg/min intravenously (IV). The IV bag contains dobutamine 500 mg in dextrose 5% in water (D5W) 500 mL. How many mL/hour should the nurse program the IV infusion pump?
(Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["16"]
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mcg/min) x Weight (kg) x Volume (mL) / Concentration (mcg)
First, we need to convert the weight from pounds to kilograms by multiplying by 0.454. In this case, 176 pounds is equivalent to 79.904 kg.
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mcg/min x 79.904 kg x 500 mL / 500000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 15.981 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 16 mL/h

Correct Answer is ["30"]
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 ["30"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Volume (mL) / Time (h)
In this case, the volume and the time are given in the prescription, so we just need to plug in the values:
Infusion rate (mL/h) = 30 mL / 1 h
Simplifying, we get:
Infusion rate (mL/h) = 30 mL/h
