Patient-centered goals are established for each priority, followed by detailed nursing interventions with rationales and evaluation criteria. The case study highlights the importance of clinical reasoning in prioritizing patient care, providing specific strategies for pain relief, blood pressure management, and stress reduction to improve patient outcomes. The interventions include medication, environmental modifications, and patient education, with outcomes measured through pain scales, blood pressure monitoring, and assessing the patient's coping mechanisms.
