Discharge teaching after colonoscopy with removal of polyp
-mild cramping and flatulence resolves after 24hrs -minimal bleeding normal -report s/s of perforation (excessive bleeding, N/V, fever)
Barium enema
3 cleansing enemas before
Enzymes that act on proteins
In stomach--> pepsin and hydrochloric acid In pancreas--> trypsin
lipase
acts on lipids (triglycerids)
ptyalin (salivary amylase)
digestion of starches
When gastric analysis testing reveals excess secretion of gastric acid, which diagnosis is supported?
duodenal ulcer
bile
enzyme secreted by liver and gallbladder
Post-barium enema
increase water intake
gastrin
inhibits gastric secretion and inreases production of bicarbonate-rich pancreatic juices, thus inhibiting gastric motility
increases gastric juices
gastrin
Hemoccult test
avoid red meat
pepsin
protein digestion
trypsin
protein digestion (from pancreas)
Glucagon
relaxes colonic musculature and reduces spasms
inhibits gastric secretions secretions (somewhat)
secretin
Liver bx
take vitamin K before
What age-related change increases r/f anemia?
atrophy of gastric mucosa--> reduces hydrochloric acid which then impairs absorption of iron and vitamin b12
Barium swallow
avoid smoking at least 1 day before
(((((((Prepping for barium swallow
avoid smoking for 24 hours before
hydrogen breath test evaluates absorption of?
carbohydrates
increases gastric secretions
cholecystokinin
most common symptom in GI dysfunction
dyspepsia (indigestion)
Excessive vomiting puts pt at r/f which acid-base imbalance?
metabolic alkalosis and hypokalemia
inhibitors effect on gastric secretions
neuroregulator: epinephrine
Which procedure is performed to examine and visualize lumen of small bowel?
small bowel enteroscopy
((((((Prepping for barium enema
three cleansing enemas before
***********************************Prepping for liver bx
vitamin k beofre
landmark for upper boundary for auscultating bowel sounds
xiphoid process
