Answer and Explanation

The Correct Answer is ["0.25"]

Dopamine infusion calculation based on weight and concentration.

  • Dopamine dose ordered: 3 mcg/kg/min
  • Dopamine concentration: 600 mg in 1000 mL (or 600 mcg/mL)
  • Client's weight: 110 pounds (converted to kg: 110 lbs / 2.2 = 50 kg)

Calculations:

  • mcg/min = 3 mcg/kg/min × 50 kg = 150 mcg/min
  • mcg/hr = 150 mcg/min × 60 min/hr = 9000 mcg/hr
  • mL/hr = 150 mcg/min / 600 mcg/mL = 0.25 mL/hr

Answers:

  • mcg/min = 150 mcg/min
  • mcg/hr = 9000 mcg/hr
  • mL/hr = 0.25 mL/hr

Correct Answer is ["22"]

Explanation

Dobutamine infusion calculation:

  • Client weight: 220 pounds
  • Dobutamine dose ordered: 5.5 mcg/kg/min
  • Dobutamine concentration: 750 mg in 500 mL
  • Conversion factor: 1 mg = 1000 mcg
  • 1 kg = 2.2 pounds

Calculations:

  • Convert client weight to kg: 220 lbs / 2.2 lbs/kg = 100 kg
  • Calculate mcg/min: 5.5 mcg/kg/min × 100 kg = 550 mcg/min
  • Calculate mcg/hr: 550 mcg/min × 60 min/hr = 33000 mcg/hr
  • Calculate mL/hr: Dobutamine concentration is 750 mg/500 mL, which equals 1500 mcg/mL.
    • mL/hr = 33000 mcg/hr / 1500 mcg/mL = 22 mL/hr

Answers:

  • mcg/min: 550 mcg/min
  • mcg/hr: 33000 mcg/hr
  • mL/hr: 22 mL/hr
