A client who weighs 91 kg receives a prescription for a continuous infusion of dopamine at 3 mcg/kg/min. The solution is labeled, "Dopamine 400 mg in 5% Dextrose Injection 250 mL." How many mL/hr should the nurse program the infusion pump to deliver?
(Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["10.2"]
- Calculate the dose of dopamine in mcg/min: 3 mcg/kg/min x 91 kg = 273 mcg/min
- Convert the dose to mg/hr: 273 mcg/min x 60 min/hr x 1 mg/1000 mcg = 16.38 mg/hr
- Calculate the infusion rate in mL/hr: 16.38 mg/hr x 250 mL/400 mg = 10.24 mL/hr
- Round to the nearest tenth: 10.2 mL/hr
- Program the infusion pump to deliver 10.2 mL/hr

- The nurse should program the infusion pump to deliver 200 mL/hour of daptomycin solution
- The answer is 200 (mL/hour)
Correct Answer is ["125"]
Explanation
- Calculate the infusion rate in mL/hour using the formula: infusion rate (mL/hour) = volume (mL) / time (hours)
- Plug in the given values: infusion rate (mL/hour) = 1000 mL / 8 hours
- Simplify the expression: infusion rate (mL/hour) = 125 mL/hour
- The nurse should program the infusion pump to deliver 125 mL/hour
