This case study analyzes the health alterations of Mr. Smith, a 70-year-old patient admitted with severe chest pain and chronic heart failure. The paper utilizes the ABCDE framework to identify impaired gas exchange and excess fluid volume as primary healthcare priorities. It then details three evidence-based interventions: controlling mineral consumption, providing oxygen therapy, and implementing breathing exercises. The pathophysiology, management, and nursing considerations for each intervention are thoroughly discussed. Finally, a discharge plan is developed based on the social justice framework, ensuring patient involvement and education for continued care, including medication administration and breathing techniques. The analysis adheres to the requirements of the NUR241 Health Alterations course, including appropriate assessment, management, and ethical considerations.
