Question 1 of 5
The healthcare provider (HCP) prescribes dopamine 2 mcg/kg/min IV for client who weighs 60 kg. The IV bag contains 'Dopamine 400 mg in dextrose 5% in water (DW) 500 mL.' The nurse should program the infusion pump to deliver how many mL/hour? (Enter numerical value only.)
Correct Answer: A
Rationale: Calculation: 2 mcg/kg/min × 60 kg × 60 min/hour = 7200 mcg/hour. 7200 mcg/hour / 1000 = 7.2 mg/hour. Concentration = 400 mg / 500 mL = 0.8 mg/mL. Infusion rate = 7.2 mg/hour / 0.8 mg/mL = 9 mL/hour.
