This essay delves into the ethical, legal, and professional responsibilities of nurses, particularly in complex scenarios involving patient care and end-of-life decisions. It discusses bioethical principles such as beneficence and non-maleficence, examining how these principles can create dilemmas in practice, especially when dealing with unconscious patients and conflicting family opinions. The essay also addresses the legal aspects, including the importance of power of attorney, the illegality of euthanasia, and the potential legal obligations nurses face. Furthermore, it emphasizes the professional responsibilities of nurses, such as maintaining competence, promoting patient safety, and acting within legal and ethical frameworks, referencing Australian law and the need to avoid emotional decision-making. The case study of Dawn, an unconscious stroke patient, serves as a focal point to illustrate these challenges and responsibilities, highlighting the complexities involved in balancing ethical considerations, legal requirements, and professional duties in nursing practice.
