Gastrointestinal Flashcards
what is foodborne illness
food poisoning
common infective agents: staph aureus norovirus C. perfringens Salmonella botulism E. coli
foodborne management
food safety and preparation
good hand hygiene
prevent transmission
monitor fluid volume deficit
discourage use of antidiarrheals
with e. coli infection
- monitor kidney function
with botulism poisoning
- monitor neuro status
what is pernicious anemia
deficiency in production of RBCs because of lack of intrinsice factor
due to lack of intrinsic factor, vit B12 cant be absorbed
more frequently in Northern European descent and African Americans
pernicious anemia manifestations
fatigue
weakness
dyspnea
pallor and palpitations
beefy red tongue
nausea
vomiting
anorexia
diarrhea
abdominal pain
paresthesia in hands and feet
- burning or prickling sensation
impaired coordination and balance
pernicious anemia diagnostic studies
CBC
bone-marrow biopsy
low levels of gastric hydrochloric acid
Schilling test
- vit B12 absorption test
pernicious anemia care
lifelong vit b12 therapy adeuqate dietary sources of vit B12 - clams - sardines - meat - fish - milk - cheese - eggs - fortified breakfast cereals
pernicious anemia management
manage fatigue and activity intolerance
educat eclients
montitor for complications
will receive B12 injections weekly then monthly as maintenance
what is peptic ulcer disease
occurs as the resut of erosion of GI mucosa by hydrochloric acid and pepsin
risk factors of peptic ulcer disease
stress
H pylori
fam hx
use of aspirin
NSAIDs
steroids
caffeine
high alcohol intake
NSAIDs are responsible for majority of non H pylori peptic ulcers
peptic ulcer disease manifestations
pain near epigastrum nausea vomiting bloody emesis - blood vomiting tarry stools - bloody stools
peptic ulcer disease complications
hemorrhage
perforation
gastric outlet obstruction
peptic ulcer disease diagnostic studies
upper endoscopy = most accurate diagnostic procedure
stool for occult blood may be evaluated, as well as complete blood count
peptic ulcer disease care
NPO
NG tube
if acute GI bleeding, endoscopic therapy/hemostasis
srugery - if urgent
peptic ulcer disease pharmacologic interventions
proton pump inhibitors:
- pantoprazole
- omeprazole
- lansoprazole
antiinfectives if H pylori
- clarithromycin
- metronidazole
H2 receptor antagonists
- cimetidine
- ranitidne
- famotidine
anticholinergics
- dicyclomine
antacids
- aluminum hydroxide
- aluminum magnesium combinations
- calcium carbonate
metoclopramide
cytoprotective
- sucralfate
- misoprostol
peptic ulcer disease complementary health
licorice root cats claw goldenseal - little exvidence exists that support their efficacy
acupuncture
therapeutic massage
guided imagery
progressive relaxation
surgically severing vagus nerve (vagotomy) can help with gastric acid secretion
- for clients who do not respond to medical management
what is GERD
syndrome, not a disease
GERD manifestations
based on symptoms
increased by bending, stooping, lying down, or eating
usually relieved by antacids
nausea after eating is common
GERD diagnostic studies
endoscopy
manometry studies
- to evaluate LES and esophageal mobility
scintigraphy
- assess gastric emptying
- used with radioactive tracer to obtain an image of a bodily organ or a record of its functioning
GERD care
pharamacological interventions:
proton pump inhibitors:
- omeprazole
- lantoprazole
H2 receptor antagonists
- cimetidine
- ranitidine
- famotidine
OTC antacids
- pepto bismol
GERD management
HOb elevated, esp after meals
avoid alte night eating
administration of PPI before first meal of the day
monitor aspiration and other complications
maintain fluid and electrolyte balances
avoid foods that acidic or gas-forming
incidence of GERD increases with age
what is appendicitis
inflammation of the appendix
most common reason for emergency abdominal surgery
appendicitiy manifestations
anorexia
nausea and vomiting
right lower quadrant pain
low grade fever
localized and rebound tenderness
appendicitis diagnostic studies
physical exam
differential WBC count
urinalysis
- to rule out urinary conditions that mimic appendicitis
KUB
- kidneys, urter and bladder x ray
ultrasound of the abdomen
CT
appendicitis care
immediate appendectomy
- any delay can lead to rupture and peritonitis
what is ulcerative colitis
begins in the rectum and extends to the distal colong
causes swelling, ulcerations and loss of function of the large intestine - colon
scarring produces narrowing, thickening and shortening of the colon
ulcerative colitis manifestations
bloody diarrhea ranging from 2-3 times/day to 10-20 times/day
stools may contain pus and mucus
left-sided abdominal pain
fever
weight loss
anemia
tachycardia
dehydration
impaired abrotpion of fat soluble, vitamins such as E and K
inflammation of the eyes
liver disease
ulcerative colitis diagnostic studies
CBC
stool for occult blood
stool culture
sigmoidoscopy or colonoscopy
ulcerative colitis care
goal of treatment:
- decreased diarrhea
- formed stool
- control of bowel movement
ulcerative colitis pharmacological interventions
prednisone
infliximab
dicyclomine
drug of choice = sulfasalazine
metronidazole
diphenoxylate
methotrexate
cyclosporine
loperamide
ulcerative colitis dietary restrictions
adhere to high calorie and high protein diet
low roughage
- whole grains
- nuts
- seeds
- legumes
- fruits
- veggies
NO milk products
ulcerative colitis surgical management
proctocolectomy
colectomy
ileostomy creation
ulcerativie colitis complications
increased risk of colon cancer
fluid and electrolytes imbalances
toxic megacolon
- extreme inflammation and distention of the colon
perforation
bleeding
hemorrhage
ulcerative colitis management
manage pain
maintain optimal fluid and nutritional intake
prevent fluid and/or electrolytes imbalances
support coping mechanisms
recognize complications
ileum = most distal part of the small intestine ileus = obstruction in intestine
ilium = part of hipbone
what is crohns disease
results in swelling and dysfunction of intestinal tract
especially the small intesting
most frequent site if the distal ileum
inflammation involves all layers of the bowel wall
crohns disease manifestations
diarrhea with steatorrhea
no obvious blood or mucus in blood
