Walden University NURS 6501: Advanced Pathophysiology Week 8: Gastrointestinal System During examinations, patients often present with various symptoms. Often, these symptoms overlap multiple disorders within body systems—especially gastrointestinal (GI) disorders—further increasing the difficulty in diagnosing and treating patients. Consider a patient who presents with severe abdominal pain that has persisted for months. At first review, it might be inflammatory bowel disease or irritable bowel syndrome, but upon closer inspection and testing, gastric cancer is found. As this case outlines, it is important that you, as an advanced practice nurse, are able to identify alterations of GI disorders in order to properly diagnose patients or refer them for specialized care when necessary. This week you examine the pathophysiology of gastrointestinal disorders. You also explore common treatments and the impact of patient factors on these disorders. Learning Objectives Students will: • Compare the pathophysiology of inflammatory bowel disorder and irritable bowel syndrome • Analyze treatments for digestive disorders • Evaluate the impact of patient factors on digestive disorders • Analyze the pathophysiology of gastric acid stimulation and production • Evaluate the impact of patient factors on gastrointestinal disorders • Evaluate clinical considerations of gastrointestinal disorders • Understand and apply key terms, concepts, and principles related to alterations of the gastrointestinal system Photo Credit: Keith Brofsky/Photodisc/Getty Images Learning Resources Note: To access this week's required library resources, please click on the link to the Course Readings List, found in the Course Materials section of your Syllabus.
