Gastrointestinal Flashcards
(89 cards)
Constipation that involves difficulty expelling stool because of failure of the pelvic floor muscles or anal sphincter to relax with defecation
Pelvic floor dysfunction or outlet dysfunction
Diarrhea where a nonabsorbale substance in the intestine draws water into the lumen by osmosis and increases stool weight and volume producing large volume diarrhea
osmotic diarrhea
The rapid emptying of hypertonic chyme from the surgically created, residual stomach into the small intestine 10 to 20 minutes after eating
Dumping syndrome
Which type of diarrhea is usually caused by an inflammatory disorder of the intestine such as ulcerative colitis, Crohn disease or microscopic colitis
Small-volume diarrhea
Diarrhea caused by resection of the small intestine (short bowel syndrome), surgical bypass of an area of the intestine, fistula formation between loops of intestine, irritable bowel syndrome
motility diarrhea
this pain arises from the parietal peritoneum, is more localized and intense
Parietal pain
This pain arises from a stimulus acting on mechanical and chemical nociceptors of abdominal organs
Visceral pain
this pain is felt at some distance form a diseased or affected organ and is well localized
Referred pain
Bleeding in the esophagus, stomach, or duodenum and is characterized by frank, bright red bleeding in emesis or dark grainy digestedd blood “coffee grounds” in stool
Upper gastrointestinal bleeding
Bleeding from the jejunum or ileum of the small intestine, colon or rectum and can be caused by polyps, inflammatory bowel disease, diverticular disease, cancer, mucosal vascular ectasias, or hemorrhoids
Lower gastrointestinal bleeding
Bleeding caused by slow chronic blood loss. Is not obvious and results in iron deficiency anemia
Occult bleeding
What are the best indicators of massive blood loss in the gastrointestinal tract
Changes in blood pressure and heart rate
Why are hematocrit and hemoglobin values not the best indicator of acute GI bleeding?
Because plasma and red cell volume are lost proportionately
Symptoms of severe GI blood loss may include?
Light headedness, loss of vision, tachycardia, hypovolemic shock, decreased urine output
Bloody vomitus; either fresh, bright red blood or dark, grainy, digested blood with “coffee grounds” appearance
Hematemesis
Black, sticky, tarry, foul-smelling stools caused by digestion of blood in the GI tract
Melena
Fresh, bright red blood passed from the rectum
Hematochezia
Trace amounts of blood in normal appearing stools or gastric secretions; detectable with a guaiac test
Occult bleeding
Difficulty swallowing or preception of obstruction during swallowing
Dysphagia
This type of dysphagia originates outside the esophogeal lumen and narrow the esophagus by pressing inward on the esophageal wall
Extrinsic mechanical obstruction dysphagia
A rare disorder related to the loss of inhibitory neurons in the myenteric plexus with smooth muscle atrophy in the middle and lower portions of the esophagus causing functional obstruction of the lower esophagus. Food accumulates above the obstruction, distends the esophagus, and causes dysphagia. Ad hydrostatic pressure increases food is slowly forced past the obstruction into the stomach
Achalasia
Heartburn, chronic cough, asthma attacks, laryngitis, sinusitis, upper abdominal pain within 1 hour of eating. Symptoms worsen if the individual lies down or if intra-abodminal pressure increases
GERD
A rare idiopathic inflammatory disease of the esophagus characterized by esophageal infiltration of eosinophils associated with atopic disease including asthma and fool allergies.
Eosinophilic esophagitis
A type of diaphragmatic hernia with protrusion of the upper part of the stomach through the diaphragm and into the thorax
hiatal hernia
