NURS 6051 Knowledge Check: Cardiovascular and Respiratory Disorders

Week 3: Concepts of Cardiovascular and Respiratory Disorders
NURS 6051 Knowledge Check: Cardiovascular and Respiratory Disorders
The circulatory system and the respiratory system are powerful partners in health. While they work closely together in good health, a disease or disorder that manifests in one can have a significant impact on both, hampering the pair’s ability to collaborate.
Cardiovascular and respiratory disease and disorders are among the most common reasons for hospital visits, and among the leading causes of fatality. Heart disease and pneumonias are among the most familiar, but a wide variety of issues can impact physiological functioning of one or both systems.
This week, you examine fundamental concepts of cardiovascular and respiratory disorders. You explore common diseases and disorders that impact these systems, and you apply the key terms and concepts that help communicate the pathophysiological nature of these issues to patients.
Learning Objectives
Students will:
Analyze concepts and principles of pathophysiology across the lifespan
