MSN5100 Advanced Pathophysiology Course Description
Course Description
This graduate-level course builds upon undergraduate pathophysiology knowledge to provide an in-depth exploration of the biologic basis of disease in adults and children across the lifespan. Students examine alterations in cellular and tissue function, adaptive and maladaptive responses to stressors, and the pathogenesis, etiology, clinical manifestations, and complications of selected diseases. Emphasis is placed on integrating concepts of genetics, environment, inflammation, immunity, and systemic interactions to support advanced nursing practice, clinical decision-making, differential diagnosis, and evidence-based interventions.
The course uses a systems-based approach while highlighting core mechanisms such as cell injury, inflammation, genetic influences, and neoplastic processes. It prepares MSN students (e.g., for NP, CNS, or educator roles) to analyze complex patient presentations, recognize risk factors, and apply pathophysiological principles in diverse clinical settings.
