A patient weighing 90 kg is to receive an infusion at 10 mcg/kg/min. The solution contains 1200 mcg/mL. What infusion rate is needed in mL/h?
Answer and explanation
Correct answer: B. 45 mL/h
- Step 1: Dose per minute mcg/min, i.e. mcg/h.
- Step 2: Rate mL/h.
Answer
45 mL/h.
Why not the others: 0.75 mL/h: The conversion from minutes to hours was left out. 2700 mL/h: The conversion to hours was applied twice. 0.5 mL/h: The weight was left out.
