---|---|
suppresses peristalsis and decreases gastric emptying | dicyclomine HCL (Bentyl) |
slow peristalsis and segmental contractions, often resulting in constipation | opioid analgesics |
inhibit gastric acid secretion and depress GI motility. although useful in treating hyperactive bowel disorders,causes constipation | anticholinergic drugs such atropine or glycopyrrolate (Robinul) |
produce diarrhea by disrupting the normal flora in the GI tract. an increase in the use of fluoroquinolones in recent years has provided a selective advantage for the epidemic of c. diff | antibiotics |

when irrigating a colostomy the nurse uses __ | a cone-tipped irrigator |
an obstruction high in the small intestine causes a loss of gastric hydrochloride | metabolic alkalosis |
an obstruction at the end of the small intestine and lower in the intestinal tract causes loss of alkaline fluids | metabolic acidosis |
obstruction below the duodenum but above the large bowel results ____ | loss of both acids and bases so there is typically no imbalance |
