Administer Dopamine 3 mcg/kg/min. The client weighs 176 pounds. The drug is available as 500 mg in 250 mL of fluid. Calculate mcg/min, mcg/hr, and mL/hr. (Do not round your answer and include unit of measure with each answer)
Answer and Explanation

The Correct Answer is ["7.2"]

Dopamine infusion calculation:

  • Client weight: 176 pounds
  • Dopamine dose ordered: 3 mcg/kg/min
  • Dopamine concentration: 500 mg in 250 mL
  • Conversion factor: 1 mg = 1000 mcg
  • 1 kg = 2.2 pounds

Calculations:

  • Convert client weight to kg: 176 lbs / 2.2 lbs/kg = 80 kg
  • Calculate mcg/min: 3 mcg/kg/min × 80 kg = 240 mcg/min
  • Calculate mcg/hr: 240 mcg/min × 60 min/hr = 14400 mcg/hr
  • Calculate mL/hr: Dopamine concentration is 2 mg/250 mL, which equals 2000 mcg/mL.
    • mL/hr = 14400 mcg/hr / 2000 mcg/mL = 7.2 mL/hr

Answers:

  • mcg/min: 240 mcg/min
  • mcg/hr: 14400 mcg/hr
  • mL/hr: 7.2 mL/hr
