The healthcare provider prescribes an IV solution of isoproterenol 1 mg in 250 mL of Dextrose in Water (D/W) at a rate of 300 mcg/hour. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only.)

The healthcare provider prescribes an IV solution of isoproterenol 1 mg in 250 mL of Dextrose in Water (D/W) at a rate of 300 mcg/hour. Since 1 mg is equivalent to 1000 mcg, the concentration of isoproterenol in the IV solution is 4 mcg/mL (1000 mcg / 250 mL). Since the healthcare provider prescribes 300 mcg/hour of isoproterenol, the nurse should program the infusion pump to deliver 75 mL/hour of the IV solution (300 mcg/hour / 4 mcg/mL).
