Worked example

IV flow rate (mL/hr) - practice problem 6

An order reads: infuse 100 mL of D5W over 1.5 hours using an IV pump.

Volume100 mL

Time1.5 hr

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

Answer: 67 mL/hr

Step-by-step solution

1. Divide the volume by the time in hours

100 mL ÷ 1.5 hr

= 66.67 mL/hr

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

66.67 mL/hr ≈ 67 mL/hr

= 67 mL/hr
