A patient weighing 90 kg is to receive an infusion at 2 mcg/kg/min. The solution contains 2400 mcg/mL. What infusion rate is needed in mL/h?
Answer and explanation
Correct answer: B. 4.5 mL/h
- Step 1: Dose per minute mcg/min, i.e. mcg/h.
- Step 2: Rate mL/h.
Answer
4.5 mL/h.
Why not the others: 0.07 mL/h: The conversion from minutes to hours was left out. 270 mL/h: The conversion to hours was applied twice. 0.05 mL/h: The weight was left out.
