This report examines the principles of patient-centered care within the context of professional nursing, using a case study of a patient named Raymond. It emphasizes the importance of effective communication, cultural competence, and the development of therapeutic relationships between nurses and patients. The report highlights the need for nurses to understand and respect patients' cultural backgrounds, values, and preferences, particularly in the case of a patient from a Vietnamese background. It provides practical examples of how nurses can adapt their communication styles to ensure patient comfort and trust, including non-verbal cues and appropriate addressing. Furthermore, the report stresses the significance of detailed documentation, including the use of formats like ISBAR, to ensure continuity of care and prevent errors. The ultimate goal is to provide high-quality, safe care that respects the patient's autonomy and promotes their overall well-being, as demonstrated through interventions such as addressing smoking behaviors and providing relevant health education.
