Question

An IV is infusing at 120 mL/h. The concentration in the IV bag is 20 mg in 200 mL NS. What is the dosage rate in mg/min?

Answer 1

0.2 mg/min

Step-by-step explanation:

The IV bag is 20 mg/ 200 ml or 0.1 mg/ml

The rate is 120 ml/hr or 120 ml/hr x 0.1 mg/ml = 12 mg/hr

which is 12 mg/ 60 min = 0.2 mg/min
