CHP 21: GI EMERGENCIES Flashcards
two behavioral risk factors for GI disorders
smoking and excessive alcohol comsumption
which organ produces bile
liver
what does the pancreas produce
enzymes to break down proteins, fats, and carbs
insulin, somatostatin, glucagon
which organ stores bile
gallbladder
which organ filters blood
spleen
where is the stomach located
left upper quadrant
where is the liver located
right side of central upper abdomen
where is the spleen located
left upper abdomen
what is the major site for chemical breakdown of food and vitamin absorption
duodenum
what is the major site for water reabsorption
colon
where does 90% of absorption occur
small intestine
what does pancreatic juice do
helps neutralize gastric acid
what organ converts glycogen to glucose
liver
what does the appendix secrete
T and B lymphocytes and immunoglobulin A
why is SpO2 not reliable with GI bleeds
pt’s can have decreased hemoglobin levels
what is melena
black, tarry stool
what is cholecystitis and what usually causes a flareup of it
inflammation of the gallbladder
fatty meals
what are striae
stretch marks
what is a scaphoid abdomen a result of
decreased abdominal volume (diaphragmatic hernia, dehydration, malnutrition)
what is borborygmi
stomach growling
how should the abdomen sound to percussion
tympanic (empty)
rebound tenderness is also called what
parietal pain
visceral pain
-origin
-description
-cause
hollow organs
dull, cramping, poorly localized
organ contracts too much or is distended
parietal pain/rebound pain
-origin
-description
-cause
peritoneum
steady, achy pain, easy to localize, increases with movement
inflammation of peritoneum
somatic pain
-origin
-description
-cause
peripheral nerve tracts
localized deep pain, sharp/stabbing
irritation or injury to tissue
referred pain
-origin
-description
-cause
peripheral nerve tracts
pain originating in stomach and causing pain elsewhere
occurs after initial visceral, parietal, or somatic pain
3 vitals showing significant volume loss during orthostatic BP
decrease in systolic BP by 20
increase in diastolic BP by 10
increase in HR by 20
S/S of hyponatremia
low sodium - muscle weakness, cramps, coma, convulsions
S/S of hypernatremia
coma, convulsions
S/S of hypokalemia
muscle cramps, weakness, paralysis, dysrhythmias, flattened T waves, U waves
S/S of hyperkalemia
muscle weakness, cramps dysrhythmias, tall T waves
what is hematochezia
bright red blood in the stool
what causes esophagogastric varices
pressure increases in the blood vessels that surround the esophagus and stomach
what is pruritus
itching
what is Mallory-Weiss syndrome
vomiting increases pressure and junction between esophagus and stomach tears - does not go entirely through esophagus wall
what is Boerhaave syndrome
occurs during vomiting, esophagus tears longitudinally completely through wall
how to differentiate Boerhaave from other throat bleeding
sudden upper chest pain and little bleeding, swallowing exacerbates pain
