Question 1 of 5

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.)

Correct Answer: A

Rationale: Calculation: 15 mcg/min × 60 min/hour = 900 mcg/hour. 900 mcg/hour / 1000 = 0.9 mg/hour. Concentration = 50 mg / 250 mL = 0.2 mg/mL. Infusion rate = 0.9 mg/hour / 0.2 mg/mL = 4.5 mL/hour, rounded to 5 mL/hour.
