NR507 – Advanced Pathophysiology
Exam Study Guide – Final Study Guide
Key Concepts to Study
Gastrointestinal Pathologies (Week 5)
GERD:
• Pathophysiology: Dysfunctional lower esophageal sphincter → acid reflux →
esophageal mucosa irritation.
• Signs/Symptoms: Heartburn, regurgitation, chest pain, dysphagia.
• Pharmacologic Management: Antacids, H2 blockers, PPIs.
• Risk Factors for Esophageal Stricture: Chronic reflux, Barrett’s esophagus, chronic
inflammation.
• Hiatal Hernia Treatment: Lifestyle modification, acid suppression, surgical repair if
severe.
Appendicitis:
• Pathophysiology: Obstruction of appendix lumen → bacterial overgrowth →
inflammation → ischemia.
• Symptoms: RLQ pain, McBurney point tenderness, nausea, vomiting, low-grade
fever.
• Diagnosis via Labs: Elevated WBC, neutrophilia; imaging: CT scan.
• Adult Appendectomy Risks: Infection, abscess, perforation, post-op ileus.
Peptic Ulcer Disease (PUD):
• Pathophysiology: Mucosal erosion due to H. pylori, NSAIDs, acid/pepsin imbalance.
• Risk Factors: H. pylori infection, NSAID use, smoking, alcohol, stress.
• Gastric vs. Duodenal Ulcers: Gastric → pain worsens with eating; Duodenal → pain
improves with eating.
• Causes of Gastric Ulcers: H. pylori, NSAIDs, chronic gastritis.
• Duodenal Ulcer Signs/Symptoms: Epigastric pain, nocturnal pain, relief with
food/antacids.
Inflammatory Bowel Disease (IBD):
• Ulcerative Colitis: Mucosal inflammation, continuous lesions; Symptoms: bloody
, diarrhea, tenesmus.
• Crohn’s Disease: Transmural inflammation, skip lesions; Symptoms: abdominal
pain, diarrhea, malabsorption.
