Question 18 :
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.)
Correct Answer: ["30 mL\/h"]
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
