A nutrition consult was completed on 3/27, and enteral feedings were initiated. Mr. Hayato was started on Isosource HN @ 25 cc/hr continuously over 24 hours

What will be an ideal response?


a. At this rate, how many kcal and grams of protein should he receive per day?

• Isosource HN provides 1.2 kcal/mL and 0.0536 g protein/mL (18% total kcal).
• 25 cc/hr provides 720 kcal and 32 g protein.

b. Calculate his nutrition prescription utilizing this enteral formula. Include the goal rate, free water requirements, and the appropriate progression of the rate.

• Goal rate would be 56 cc/hr, which would provide 72 g protein, 1613 kcal, and 1344 mL of formula .
• Isosource HN contains 818 mL water per L, so 1344 mL of formula would provide 1099 mL of water.
• Using 1600 mL as his fluid requirements, he will need an additional 500 mL of water.
• The rate should be progressed by 10 mL/hr for every 8 hrs. This lower rate of progression may help as he appears to have gastric emptying issues.
