Administer a continuous Dopamine infusion at 3 mcg/kg/min. The drug is available as 600 mg in 1000 ml of fluid. The client's weight is 110 pounds. Calculate mcg/min, mcg/hr, and ml/hr. (Include unit of measure with each answer)
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
