Question

An IV is infusing at 80 ml/h potassium chloride 20mEq was added to 1000 mL of IV solution. How much potassium chloride is administered per hour in mEq/h?

Answer 1

From the given data,

IV infusing KCl at the rate = 80 ml/h

concentration of KCl = 20 mEq

volume to which KCl added = 1000 ml IV solution,

So,

KCl administered per hour = 20 mEq x 80 ml/h x 1/1000 ml

                                           = 1.6 mEq/h
