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 ["0.9"]
Explanation
To calculate the volume of filgrastim solution, we need to use the formula:
Volume (mL) = Dose (mcg) / Concentration (mcg/mL)
First, we need to calculate the dose by multiplying the prescribed rate by the weight in kilograms. To convert the weight from pounds to kilograms, we multiply by 0.454. In this case, 190 pounds is equivalent to 86.26 kg.
Plugging in the given values, we get:
Volume (mL) = 5 mcg/kg/day x 86.26 kg / 480 mcg/mL
Simplifying, we get:
Volume (mL) = 0.897 mL
Rounding to the nearest tenth, we get:
Volume (mL) = 0.9 mL
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
