NURS8022 Pathophysiology Exam #4
Achalasia - answer Failure of lower esophageal sphincter to relax that progresses to
failure to contract in later disease
Thought to be parasympathetic dysfunction
Gastrin - answer Stimulates release of gastric acid and gastric motility
Secretin - answer Inhibits gastric secretion and stimulates pancreas to release
bicarbonate to neutralize HCl
Motilin - answer stimulates gastric motility
Cholecystokinin (CCK) - answerAids in fat digestion
- triggers release of pancreatic enzymes
- causes gallbladder to contract and release of bile
- delays gastric emptying
Acute gastritis is associated with - answerH. pylori, NSAIDs, drugs, chemicals
Chronic fundal gastritis (type A) - answerimmune
Chronic antral gastritis (type B) - answerNon-immune, H. pylori and NSAIDs
Factors that promote gastric acid secretion - answerGastrin, acetylcholine, histamine
Factors that inhibit gastric acid secretion - answerSecretin, somatostatin,
prostaglandins, vasoactive intestinal peptide
Vitamin A deficiency - answernight blindness
Vitamin D deficiency - answerdecreased calcium absorption, bone pain, osteoporosis,
fractures
Vitamin K deficiency - answerBleeding-- increased PT, petechiae, purpura
Vitamin E deficiency - answertesticular atrophy, neurologic defects in children
Clear, gastric fluid vomit - answerpyloric obstruction
bile stained fluid vomit - answerproximal small intestine obstruction
