GI

abdominal assessment inspection

jaundice
distended (fluid, stool, air)
scars on abdomen
drains, ostomy

what kind of sedation do patients get for sigmoidoscopy

no sedation

colostomy vs ileostomy

colostomy - formed stool
ileostomy - liquid stool (skin care is important)

what organ has a big effect on the gi tract

pancreas

upper gi

esophagus, stomach, small intestine

propofol

watch respirations, bp

what labs are important with GI system

liver function tests
urine bilirubin
fecal occult blood test, stool samples

for fecal occult blood test, med restrictions 7 days prior include

anticoags, NSAIDS, vit c rich foods, red meat chicken and fish

what kind of sedations do patients get for endoscopy

conscious sedation

endoscopies become routine after age

50 and 40y/o with high risk or family history

complications of scopes

oversedation, poor respiratory, abnormal bp

what happens when a pt has a perforated gi tract

high risk for infection because of bacteria leaving and going into the body where it shouldnt be

contributing factors to GERD

fatty/fried foods, chocolate, caffeine, alcohol, peppermint, spicy food, tomato, citrus

sx of GERD

burping, pyrosis that goes away with sips of water, pain that worsens when laying flat, tooth erosion, pain after eating and lasts 20 min to 2 hrs

meds for GERD

omeprazole, pantoprazole, esomeprazole, lansoprazole
aluminum hydroxide, magnesium hydroxide, calcium carb, sodium bicarb

nursing considerations for GERD

monitor electrolytes, long term use of PPIs places them at risk for fractures

how much time should be between histamine2 and antacid

at least 1 hr

histamine2 meds

ranitidine, famotidine, aizatidine

nursing considerations for famotidine

take one hr before meals

esophageal varices

usually linked to alcohol (cirrhosis of liver causes congestion causing veins to surface)

alcohol

natural blood thinner

sx of esophageal varices

may be no sx until varices begin to bleed, but hematemesis maybe coffee ground appearance, melena stools (bloody stool), mental status change

why does mental status change occur with blood loss

because most blood goes to heart and brain so if brain isnt getting enough, theyre going to feel like theyre going to pass out

things that precipitate bleeding

bearing down, lifting heavy objects, coughing/sneezing, alcohol consumption

nursing interventions for esophageal varices

get IV access with large needle, vital signs, hct and hgb, get blood type for possible blood transfusions, monitor stool for blood

what is peptic ulcer disease caused by

infection from h. pylori

what med promotes ulcers in the gi tract

steroids
usually when prescribed, they will also get a gi protector to go along with it

peptic ulcer H2 receptor meds

ranitidine, famotidine

pernicious anemia

body cant absor vit b12

acute and chronic gastritis causes

autoimmune disease or bacterial infection

nursing care for gastritis

i&o, electrolytes, small frequent meals, avoid irritants (alcohol, caffeine), reduce stress

nonmechanical cause of obstruction

ileus - gi tract just stops functioning - maybe nc of anesthesia
