This nursing case study assignment focuses on Acute Coronary Syndrome (ACS), a critical condition and leading cause of death. The paper examines a patient presenting with ACS symptoms, delving into modifiable and non-modifiable risk factors like smoking and lack of exercise, alongside health promotion strategies. It explores the pathophysiology of STEMI and NSTEMI, explaining how blood clots obstruct blood flow to the heart, causing chest pain and other symptoms, and the homeostatic mechanisms leading to referred pain and skin changes. The assignment further outlines crucial nursing care interventions, including pain management, patient education, and continuous monitoring to improve health outcomes. The role of the nurse in managing ACS, from hospital care to patient education for long-term health, is emphasized.
