This assignment is an annotated bibliography created by Radhika Chand for the 2806NRS Research in Nursing course at Griffith University. It focuses on the case of William, a 75-year-old man with worsening chronic heart failure. The bibliography comprises three research papers exploring exercise-based rehabilitation, interventions to enhance medication adherence, and dietary approaches for patients with heart failure and diabetes. Sagar et al.'s study examines exercise-based rehabilitation, while Molloy et al. investigates medication adherence. Butler et al. explores dietary recommendations. The report then analyzes the strengths of these studies in relation to William's case, highlighting the importance of exercise, nutritional management, and medication adherence. The report concludes by recommending specific interventions based on the research findings to improve William's quality of life and manage his condition.
