A client experiencing ventricular tachycardia receives a
prescription a continuous infusion of dextrose 5% in water
(D5W)1000 ml with lidocaine (Xylocaine) 2 grams at a rate of
4 mg per minute. The nurse should program the infusion

(Enter numeric value only.) - Correct Answers ✅First
convert solution gram/ml to mg/ml:
2gm/1000ml = 2000mg/1000ml = 2 mg/ml
Next calculate # of mg/hr for the dose:
4 mg X 60 mins = 240 mg/hour
Next calculate # ml/hr to give 240 mg/hr:
2000 mg: 1000 ml :: 240 mg : X ml
2000/240 = 1000/XX = 120 ml/hour
