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

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
