Chapter 21

EKG Class and Upcoming Chapters

  • Chapter 22: Electrical activity in the heart, covered in EKG class.
  • Chapter 26: Also covered in an EKG class on a Sunday after you leave the hospital early.
  • Exam/Quizzes:
    • EKG check-off quiz similar to the blood administration quiz, containing about 15 to 20 questions (striving for closer to 20 for better passing chances).

Schedule Details

  • Clinical and EKG Class:
    • Students are to leave the hospital early to attend EKG class.
    • Class scheduled post-lunch after clinical duties on the designated Sunday.

Unit Three Overview

  • Chapter Coverage in Class:
    1. Chapter 22: Electrical activity during EKG.
    2. Chapter 23: Focus on coronary artery disease (MIs) - covered in traditional lecture format.
    3. Chapter 24: Voice-over PowerPoint recording containing mostly definitions.
    4. Chapter 25: Heart failure discussed as a culmination of concepts from Unit Two and Unit Three, to be taught in class format.

Chapter Discussions and Resources

  • Diuretics Discussion:

    • Understanding diuretics is crucial for discussions on heart failure. Ensuring students are aware of Chapter discussions.

  • EPA Submission:

    • All instructions for the assignment will be accessible on Blackboard.
    • Encouragement to complete assignments during fall break for better retention.

  • Materials Available:

    • PowerPoint slides and cardiac visuals, particularly a focus on heart anatomy and physiology.

Chapter 21: Overview of Cardiovascular System

  • Content Focus:

    • Extensive discussion on anatomy and physiology of the cardiovascular system.
    • Importance of undergoing thorough cardiovascular assessments during clinical practice.

  • Key Concepts in Assessment:

    • Cardiovascular assessment is essential for every patient due to their systemic relevance.

Learning and Study Techniques

  • Worksheets & Study Guides:

    • Some students expressed disinterest in traditional aids. Instructor aiming for worksheets to help streamline studying.
    • Importance of not trying to memorize the textbook; focus on understanding key concepts.

  • Concepts to Emphasize:

    • Polycythemia defined as having too many red blood cells; recall that tests may address this concept.
    • The usefulness of using PowerPoint as a study guide, with a suggestion that test questions may come from worksheets and assignments.

Importance of Proper Assessment

  • Head to Toe Assessments:
    • Instructor emphasizes the necessity of thorough assessments to ensure adequate patient care and documentation.
    • Various patient experiences highlight discrepancies in assessment procedures across healthcare environments.

Understanding Patient Conditions

  • Perfusion Concepts:

    • Definition of perfusion is crucial; it pertains to oxygen delivery to tissues.
    • Discussed interconnectivity of oxygenation and perfusion in patient assessments.

  • Complications of Heart Failure:

    • Describes conditions of left-sided and right-sided heart failure, detailing backflow issues that arise.
    • Left-Sided Heart Failure: Leads to fluid accumulation in lungs, causing symptoms like crackles and dyspnea.
    • Right-Sided Heart Failure: Causes fluid build-up in the venous system, resulting in edema and discomfort.

Cardiac Output and Ejection Fraction

  • Definitions:
    • Cardiac Output: The amount of blood the left ventricle pumps out per minute, typically measured in liters (4-8 L/min).
    • Ejection Fraction: The percentage of blood leaving the left ventricle with each heartbeat; desired range is 55-60%.

Assessment and Clinical Relevance

  • Systemic Assessment in Cardiac Care:
    • Complementary systems must be assessed to evaluate cardiovascular health, including renal output, neurological status, and respiratory function.
    • Reference for diagnostic tests, emphasizing understanding of what tests involve, their purpose, and necessary nursing considerations.

Diagnostic Tests in Cardiovascular Care

  • Key Components to Study:
    • What happens during a diagnostic test?
    • The rationale behind the test - what conditions is it exploring?
    • Specific nursing measures for patient care in relation to the tests (e.g., heart cath)

Diagnostic Test Highlights

  • Heart Catheterization (Heart Cath):

    • Importance of post-procedure care including pressure dressings, neurovascular assessments, and consideration of medications given during the procedure (e.g., heparin).

  • General Tips for Break and Beyond:

    • Encourage students to utilize downtime during the fall break to tackle EPA assignments for greater retention and understanding.

Final Thoughts

  • Instructor urges students to utilize resources effectively and emphasizes the importance of comprehensive assessment in nursing practice.
  • Reflecting on personal experiences in acute care settings and addressing current practices during patient care to foster discussion and awareness among future nurses.
