Chapter 25:
Coronary Artery Disease (CAD): Pathophysiology and Clinical
Manifestations
Describe the pathophysiology, clinical manifestations, and management of coronary artery disease.

By mastering these principles, nurses can provide evidence-based, high-quality care to patients with cardiac disorders, improving survival and quality of life.
Chapter 26
Peripheral Circulation and Factors Affecting Blood Flow
Identify anatomic and physiologic factors that affect peripheral blood flow and tissue oxygenation. Peripheral circulation is influenced by __________, __________, and __________. When circulation is impaired, tissues may not receive adequate __________, leading to ischemia and damage. A 70-year-old male with a chronic smoking history and diabetes presents with intermittent leg pain during walking that resolves with rest. What vascular condition might be causing his symptoms? 🩺 Clinical Example: This patient is likely experiencing __________, which results from narrowed arteries limiting blood flow to the lower extremities. 🗣 Socratic Question: "Why does exercise induce pain in PAD, and why does rest relieve it?" ✅ Key Concept: In PAD, __________ during activity exceeds available oxygen supply, leading to pain that improves with rest.
Assessment of Peripheral Circulation
Apply assessment parameters appropriate for determining the status of peripheral circulation. Nurses assess peripheral circulation by evaluating __________, __________, and __________. One important finding that differentiates arterial from venous disease is how extremities respond to __________. A patient with PAD is noted to have pale, cool feet that become red when dangling off the bed. What does this suggest about their circulation?
🩺 Clinical Example: The patient exhibits __________, a sign of __________ insufficiency, where blood pools due to gravity-dependent positioning. 🗣 Socratic Question: "Why do arterial insufficiency patients experience pallor when the leg is elevated but redness when lowered?" ✅ Key Concept: __________ decreases arterial blood supply, while dependency allows gravity to aid perfusion.
Nursing Process in Arterial and Venous Disorders
Use the nursing process as a framework for care of the patient with arterial and venous disorders. Management of arterial and venous disorders differs based on their pathophysiology. Nurses play a critical role in educating patients on symptom management and prevention. A patient with chronic venous insufficiency (CVI) presents with bilateral leg swelling, brown skin discoloration, and aching pain that worsens after standing for long periods. What is the primary nursing intervention? 🩺 Clinical Example: The nurse should instruct the patient to __________, which helps improve venous return and reduce edema. 🗣 Socratic Question: "Why does leg elevation improve symptoms in venous disease but worsen symptoms in arterial disease?" ✅ Key Concept: Venous disease benefits from __________, while arterial disease worsens due to reduced arterial perfusion.
🩺 Clinical Example: The patient’s symptoms suggest __________, requiring immediate ____________ of the affected leg and initiation of __________ therapy to prevent __________. 🗣 Socratic Question: "Why should patients with suspected DVT avoid ambulation until anticoagulation is initiated?" ✅ Key Concept: Movement may dislodge a clot, increasing the risk of __________.
Lymphatic Disorders and Cellulitis
Describe the pathophysiology, clinical manifestations, and management of lymphatic disorders and cellulitis. Lymphatic disorders, such as lymphedema, occur when lymphatic drainage is impaired, leading to fluid accumulation in tissues. Cellulitis , a bacterial skin infection, often develops due to impaired circulation. A patient with chronic lymphedema presents with a warm, red, swollen lower leg and fever. What complication is the nurse most concerned about? 🩺 Clinical Example: These symptoms indicate __________, requiring immediate __________ therapy to prevent systemic infection. 🗣 Socratic Question: "Why are patients with lymphedema at higher risk for developing cellulitis?" ✅ Key Concept: Impaired lymphatic drainage reduces __________, allowing bacteria to proliferate.
