Exam 5- NURS 5315 GI Module 9 Questions and
Answers
Upper GI organs Correct-mouth,pharynx, esophagus, stomach, and duodenum
Lower GI organs Correct-small intestine, large intestine, rectum and anus

intestines. This pulls water by osmosis into the intestinal lumen and results in large volume
diarrhea. This is how mag citrate, lactulose and miralax work. Causes include: excessive
ingestion of nonabsorbable sugars, tube feedings, dumping syndrome, malabsorption,
pancreatic enzyme deficiency, bile salt deficiency, small intestine bacterial overgrowth or
celiac disease
