This report presents a comprehensive analysis of a nursing case study involving a 76-year-old woman named Gladys, diagnosed with Chronic Obstructive Pulmonary Disease (COPD) and presenting with right-sided heart failure. The report delves into the pathophysiology of both conditions, exploring the mechanisms of lung inflammation, airflow limitation, and right ventricular dysfunction. It outlines the relevant symptoms, diagnostic tests, and potential complications, including heart failure and respiratory failure. Furthermore, the report emphasizes the importance of considering developmental stages, cultural values, and health literacy when planning care. It identifies three key nursing priorities: managing shortness of breath, addressing complications of right-sided heart failure, and promoting patient function and mobility. The study highlights the significance of pharmacological interventions, such as bronchodilators, statins, and pulmonary rehabilitation, in improving patient outcomes and enhancing quality of life. Finally, the report underscores the need for nurses to consider individual patient needs and contexts when providing care for patients with COPD and related conditions.
