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

Correct Answer is ["250"]
Explanation
- Calculate the infusion rate using the formula: mL/hour = (mL of solution) / (hours to infuse)
- Plug in the given values: mL/hour = (500 mL) / (2 hours)
- Simplify the expression: mL/hour = 250 mL
- The nurse should program the infusion pump to deliver 250 mL/hour of azithromycin in NS
Correct Answer is ["0.8"]
Explanation
To calculate the dose of phenytoin, use the formula: Dose (mL) = (Desired dose x Volume) / Stock dose
- Plug in the values: Dose (mL) = (20 mg x 5 mL) / 125 mg
- Simplify and solve: Dose (mL) = 0.8 mL
- The nurse should administer 0.8 mL of phenytoin suspension every 8 hours.
