Worked example

IV flow rate (mL/hr) - practice problem 5

An order reads: infuse 1000 mL of 0.9% normal saline over 1.5 hours using an IV pump.

Volume1000 mL

Time1.5 hr

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

Answer: 667 mL/hr

Step-by-step solution

1. Divide the volume by the time in hours

1000 mL ÷ 1.5 hr

= 666.67 mL/hr

2. Round to a whole mL/hr the pump can be set to

666.67 mL/hr ≈ 667 mL/hr

= 667 mL/hr
