IV flow rate (mL/hr) — practice problem 7

An order reads: infuse 50 mL of D5W over 2 hours using an IV pump.

Volume50 mL
Time2 hr

What rate (mL/hr) should the pump be set to?

Answer: 25 mL/hr

Step-by-step solution

1. Divide the volume by the time in hours
50 mL ÷ 2 hr
= 25 mL/hr
2. Round to a whole mL/hr the pump can be set to
25 mL/hr ≈ 25 mL/hr
= 25 mL/hr
