This case study focuses on the management of a 60-year-old indigenous man, David, recently diagnosed with chronic obstructive pulmonary disease (COPD) and attending a pulmonary rehabilitation center. The assignment requires an analysis of the role of the registered nurse in David's care, emphasizing patient education, self-management strategies, and the importance of ongoing treatment. The nurse's responsibilities include providing care, preventing illness, and treating health conditions, along with monitoring and recording patient information. The case study also highlights the importance of patient education, particularly for chronic conditions, and the need for tailored interventions, such as diet and exercise plans, smoking cessation, and self-management techniques to improve patient outcomes. The report underscores the collaborative nature of care and the significance of nurses in guiding patients through chronic illness management.
