The tube feeding is administered at 75 ml/hour for 11 hours (0700 – 1800) and then turned off for one hour because the residual is greater than 200 ml. 11 hours x 75 ml/hr = 825 ml. Three doses of 20 ml of medication are administered, with 10 ml of water used to flush the GT before and after each dose. 20 ml x 3 doses = 60 ml; 10 ml (flush) x 2 x 3 doses = 60 ml; so 825 ml + 60 ml + 60 ml = 945 ml. 250 ml of residual is removed and not replaced. 945 ml – 250 ml = 695 ml total fluid balance (Intake – output).

A client with a gastrostomy tube (GT) receives a prescription for Osmolite® 1/2 strength enteral formula at 80 ml/hour. To prepare a 4 hour solution, the nurse should dilute the full-strength formula with how many ml of water? (.)

Determine the total volume needed at 80 ml/hour x 4 hours = 320 ml. Use the formula, Desired strength/strength on Hand x Volume = 50/100 x 320 = 160 ml of Osmolite® enteral formula, which must be diluted to half strength. Or use ratio and proportion, Desired strength (1/2 = 1 part : 2 parts) :: Volume of full strength : Total Desire volume 1 : 2 :: X : 320 ml 2X = 320, and X = 160 ml of OsmoliteÂ® enteral formula, full strength 320 ml total volume – 160 ml of full-strength formula = 160 ml of water to create 1/2 strength or 50% concentration.
