Question 1 of 5
The client in a code is now in ventricular bigeminy. The HCP orders a lidocaine drip at three (3) mg/min. The lidocaine comes prepackaged with two (2) grams of lidocaine in 500 mL of D5W. At which rate will the nurse set the infusion pump?
Correct Answer: 45
Rationale: Lidocaine concentration: 2 g = 2000 mg in 500 mL = 4 mg/mL. Dose: 3 mg/min. Rate = (3 mg/min) / (4 mg/mL) = 0.75 mL/min = 45 mL/hour (0.75 * 60). Pump set to 45 mL/hour.
