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

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 ["0.5"]
Explanation
To calculate the volume of heparin solution, we need to use the formula:
Volume (mL) = Dose (units) / Concentration (units/mL)
Plugging in the given values, we get:
Volume (mL) = 5,000 units / 10,000 units/mL
Simplifying, we get:
Volume (mL) = 0.5 mL
Rounding to the nearest tenth, we get:
Volume (mL) = 0.5 mL
