Correct Answer is ["45"]
Explanation
Infusion rate in mL/h = Dose (mcg/kg/min) x Weight (kg) x 60 / Concentration (mcg/mL) In this case, the dose is 2 mcg/kg/min and the concentration is 50 mg/250 mL or 200 mcg/mL. Therefore, the infusion rate is:
Infusion rate (mL/h) = 2 x 75 x 60 / 200 Infusion rate (mL/h) = 45
The nurse should set the IV pump to deliver 45 mL/h.
Correct Answer is ["0.5"]
Explanation
Dose / Concentration = Volume Plug in the values from the question:
10 mg / 20 mg/ml = 0.5 ml
Round the answer to the nearest tenth:
=0.5 ml
