Correct Answer is ["45"]
Explanation
Pump rate in mL/hour = Dose (mcg/kg/min) x Weight (kg) x 60 / Concentration (mcg/mL)
The concentration of nitroprusside is given as 50 mg in 250 mL of dextrose 5% in water.
Convert this to mcg/mL; multiply by 1000
Concentration (mcg/mL) = 50 mg x 1000 / 250 mL = 200 mcg/mL Therefore;
Pump rate in mL/hour = 2 mcg/kg/min x 75 kg x 60 / 200 mcg/mL Pump rate in mL/hour = 45 mL/hour
Therefore, the nurse should set the IV pump to deliver 45 mL/hour
Correct Answer is ["167"]
Explanation
To find the infusion rate in mL/hr, divide the total volume of fluid by the total time of infusion.
Total volume of fluid = 1,000 mL Total time of infusion = 6 hr
Infusion rate = 1,000 mL / 6 hr = 166.67 mL/hr
Round the answer to the nearest whole number: 167 mL/hr
