Question 19 :
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 DW. The nurse should set the Infusion pump to deliver how many mL/hour? (Enter numeric value only.)
Correct Answer: ["18 mL\/hour"]
To calculate the infusion rate, use the formula mL/hour = (dose in mcg/kg/min x weight in kg x 60 min) / (concentration in mg/mL x 1000 mcg/mg). Therefore, mL/hour = (2 x 74.8 x 60) / (50 x 1000) = 17.9. The nurse should set the infusion pump to deliver 18 mL/hour.
