    Calculation

    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.)

    mL/hr

    Explanation & Rationale

    - Calculate the dose of dopamine in mcg/min: 3 mcg/kg/min x 91 kg = 273 mcg/min - Convert the dose to mg/hr: 273 mcg/min x 60 min/hr x 1 mg/1000 mcg = 16.38 mg/hr - Calculate the infusion rate in mL/hr: 16.38 mg/hr x 250 mL/400 mg = 10.24 mL/hr - Round to the nearest tenth: 10.2 mL/hr - Program the infusion pump to deliver 10.2 mL/hr
