The drops per minute will equal the volume to be infused multiplied by the gtt/ml of the infusion set.The product is then divided by the total time the infusion is to run in minutes.
1 liter of lactated ringers over 4 hours
The administration set delivers 10 gtts/ml
gtt/minute = 1000 ml X 10 gtt/ml/240 minutes
10,000/240 = 41.7 (42)gtt/min
