An infusion of 1500 ml is given over 12 hours. What is the flow rate in ml per hour?

Answer and explanation

Correct answer: B. 125 ml/h

  1. Step 1: Rate = volume / time. Step 2. 1500 / 12 = 125 ml/h. Answer: 125 ml/h. Why not the others: 18000.008 ml/h: volume and time were multiplied. 0.008 ml/h: the ratio was inverted. 1488 ml/h: time was subtracted from the volume.
