What This Document Is
This document is an outline for Lecture 2 in Nursing I (NURS 113) at Delgado Community College, focusing on the critical concept of perfusion. It provides a high-level overview of the cardiovascular system’s role in delivering blood to the body’s tissues and the implications of impaired perfusion. This outline serves as a roadmap for the lecture, highlighting key areas of study.
Why This Document Matters
This outline is essential for students in NURS 113 as it establishes the foundational knowledge needed to understand numerous physiological processes and potential health challenges. A strong grasp of perfusion is crucial for nurses, as impaired perfusion underlies many common and serious medical conditions. It’s used at the beginning of a unit to set expectations and provide context for more detailed study.
Common Limitations or Challenges
This outline is not a substitute for attending the lecture or completing the assigned readings. It does not provide in-depth explanations of the concepts, nor does it offer clinical applications or practice scenarios. It’s a preview, designed to orient you to the lecture’s scope, not to teach you the material.
What This Document Provides
This outline details eight student learning outcomes related to perfusion, including summarizing cardiovascular physiology, identifying risk factors for cardiovascular disease, understanding assessment procedures, and describing management strategies for impaired perfusion. It also includes a structural overview of the heart – its location, the pericardium, heart wall layers, chambers (with a helpful mnemonic), and valves. Key topics covered include normal heart sounds, the conduction system, blood pressure, pulse measurement, and factors influencing both. Finally, it introduces hypertension, arteriosclerosis, and atherosclerosis, including the roles of cholesterol. This preview *does not* include detailed explanations of diagnostic tests, specific therapies, or the nursing process applied to perfusion alterations – those are covered in the full lecture.
