This paper discusses the implementation of Levett-Jones clinical reasoning cycle and Miller’s Functional Consequences Theory in identifying nursing care prioritization for Amalie, an 89-year-old woman with rheumatoid arthritis, osteoarthritis, macular degeneration, and hypothyroidism. The paper sets goals for pain, impaired physical mobility, and impaired vision, and provides actions for assessment and intervention. The outcomes show improvement in pain severity, mood, coping ability, and activities of daily living, and reduction in fall frequency.
