Worked example

IV flow rate (mL/hr) - practice problem 8

An order reads: infuse 1000 mL of D5W over 6 hours using an IV pump.

Volume1000 mL

Time6 hr

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

Answer: 167 mL/hr

Step-by-step solution

1. Divide the volume by the time in hours

1000 mL ÷ 6 hr

= 166.67 mL/hr

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

166.67 mL/hr ≈ 167 mL/hr

= 167 mL/hr
