Dobutamine hydrochloride 2 mcg/kg/min is prescribed for a client weighing 165 pounds. The solution is mixed with 50 mg of dobutamine in 1,000 mL of D5W. The nurse should set the infusion pump to deliver how many mL/hour? (Enter numeric value only.)

- Convert client's weight to kg: 165 lb / 2.2 = 75 kg - Calculate dobutamine dose in mg/min: 2 mcg/kg/min x 75 kg = 150 mcg/min - Convert dobutamine dose to mg/hour: 150 mcg/min x 60 min = 9000 mcg/hour - Convert dobutamine dose to mg/hour: 9000 mcg/hour / 1000 = 9 mg/hour - Calculate infusion rate in mL/hour: 9 mg/hour / 50 mg x 1000 mL = 180 mL/hour - Answer: The nurse should set the infusion pump to deliver 180 mL/hour.
