Question 1 of 5

A client who weighs 91 kg receives a prescription for a continuous infusion of dopamine at 3 mcg/kg/min. The solution is labeled, 'Dopamine 400 mg in 5% Dextrose Injection 250 mL.' How many mL/hr should the nurse program the infusion pump to deliver? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Correct Answer: 10.2

Rationale: Calculate dose: 3 mcg/kg/min × 91 kg = 273 mcg/min. Convert to hourly: 273 × 60 = 16380 mcg/hour. Concentration: 400 mg = 400000 mcg in 250 mL = 1600 mcg/mL. Infusion rate = 16380 / 1600 = 10.2375 mL/hour, rounded to 10.2.
