Answer 17

glucose infusion rate (GIR)

Question 18

excessive or too rapid refeeding after malnutrition or fasting

-sxs: heart or renal failture, edema

Answer 18

refeeding syndrome

Question 19

ligament of Treitz

Answer 19

marks the separation of the duodenum and jejunum. To bypass it, one would need to use percutaneous jejunostomy for feeding access.
