Chapter 3: Ethical and Legal Issues in Critical Care Nursing

Critical care nurses operate within a framework established by the American Nurses Association Code of Ethics, which requires them to serve as advocates for patients who often cannot communicate their own wishes due to sedation, mechanical ventilation, or altered consciousness. The advocacy role becomes particularly significant in intensive care settings where extended contact with patients and their families creates opportunities for nurses to understand patient values and preferences that may not be documented. Ethical decision-making in critical care requires nurses to navigate competing principles including respect for patient autonomy, the obligation to provide beneficial care while avoiding harm, and fair allocation of limited medical resources. When nurses face situations where they recognize the ethically appropriate action but cannot implement it due to institutional constraints or physician orders, they experience moral distress, which can be addressed through interdisciplinary bioethics committees and transparent communication. The chapter examines how informed consent operates in critical care, emphasizing that valid consent requires patient competence, voluntary agreement, and full disclosure of medical information. Landmark legal cases including Quinlan, Cruzan, and Schiavo have shaped how healthcare systems approach end-of-life decision-making, establishing the right to refuse treatment and highlighting the importance of advance directives such as living wills and durable powers of attorney. Critical care nurses must understand the distinction between ordinary care such as nutrition and hydration versus extraordinary care such as cardiopulmonary resuscitation and mechanical life support. Do Not Resuscitate orders provide legal documentation of patient wishes regarding resuscitation efforts. Additionally, nurses play a crucial role in organ and tissue donation processes by identifying potential donors and understanding the legal and ethical framework surrounding brain death and donation after cardiac death, while ensuring that decisions to withdraw life-sustaining treatment remain ethically separate from organ procurement decisions.
