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 ["602"]
Explanation
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) = 10 mg/min x 250 mL / 50 mg
Simplifying, we get:
Infusion rate (mL/h) = 500 mL / 50 min
Converting minutes to hours, we get:
Infusion rate (mL/h) = 500 mL / 0.83 h
Dividing both sides by 0.83, we get:
Infusion rate (mL/h) = 602.41 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 602 mL/h
Correct Answer is ["10"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Volume (mL) / Time (h)
Plugging in the given values, we get:
Infusion rate (mL/h) = 250 mL / 24 h
Simplifying, we get:
Infusion rate (mL/h) = 10.42 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 10 mL/h
