The nurse has orders for dopamine at 20 mcg/kg/min. The bag has 500 mg of dopamine in 500 mL. The client weighs 60 kg. What rate will the nurse set?
Correct Answer: 72 mL/hr
Rationale: Dose: 20 mcg/kg/min × 60 kg = 1200 mcg/min. Concentration: 500 mg/500 mL = 1 mg/mL = 1000 mcg/mL. Rate: 1200 mcg/min ÷ 1000 mcg/mL = 1.2 mL/min × 60 min/hr = 72 mL/hr.
