Lidocaine is prescribed for IV infusion via pump at 2 milligrams/minute for a client with ventricular tachycardia. The available premixed infusion contains lidocaine 4 mg/mL in D5W. To administer the prescribed dosage, how many mL/hour should the nurse set the infusion pump?
(Enter numerical value only.)
The Correct Answer is ["30"]
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mg/min) x Volume (mL) / Concentration (mg)
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mg/min x 60 min / 4 mg/mL
Simplifying, we get:
Infusion rate (mL/h) = 30 mL/h

Correct Answer is ["133"]
Explanation
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, 132 pounds is equivalent to 59.928 kg.
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mcg/min x 59.928 kg x 500 mL / 45000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 132.84 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 133 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
