# An order is written for 500 mL of NS to infuse at 40 gtt/min. How long would it take to infuse the NS if the set delivers 10 gtt/mL?

Question:

A
125 minutes

Explaination

10 gtt/mL means 10 drops per mL. So for 500 mL you will get:

10 x 500 = 5,000 drops

The flow rate is 40 gtt/min, which means 40 drops per minute, so divide total drops by 40 to get the number of minutes:

5,000/40 = 125
