The healthcare provider (HCP) changes a prescription for a nitroglycerin IV infusion from 10 mcg/min to 15 mcg/min. The IV bag contains nitroglycerin 50 mg in dextrose 5% in water (DW) 250 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Calculation: Calculate the New Nitroglycerin Dose in mcg/hour Dose (mcg/hour) = Dose (mcg/min) × 60 min/hour =15 mcg/min × 60 min/hour = 900 mcg/hour Convert mcg to mg Dose (mg/hour) = Dose (mcg/hour) / 1000 mcg/mg =900 mcg/hour / 1000 mcg/mg = 0.9 mg/hour Calculate the Concentration of Nitroglycerin in the IV Bag Concentration (mg/mL) = Total mg of Nitroglycerin / Total mL of Solution =50 mg / 250 mL = 0.2 mg/mL Calculate the Infusion Rate = Infusion Rate (mL/hour) =0.9 mg/hour / 0.2 mg/mL = 4.5 mL/hour Round to the Nearest Whole Number 4.5 mL/hour rounded to 5 mL/hour
