This assignment presents a case study on a patient experiencing systolic heart failure. It explores the pathogenesis of the condition, detailing how reduced cardiac function and external factors impact oxygen utilization in muscle cells. The case study analyzes the patient's clinical manifestations, including dyspnea, tachycardia, and low oxygen saturation, linking them to underlying conditions like hypertension and atrial fibrillation. The document also covers two crucial nursing strategies: regular monitoring of vital signs and exercise training, highlighting their role in managing the patient's condition. Furthermore, it explains the mechanism of action of two key medications, IV Furosemide and Sublingual Glyceryl Trinitrate, in treating heart failure symptoms. The document concludes with a comprehensive list of references supporting the analysis and recommendations.
