Registered Nurses frequently encounter legal and ethical dilemmas that require nuanced clinical judgment and thorough understanding of patient rights, consent law, and end-of-life regulations. Key areas include managing treatment refusal based on religious beliefs, navigating consent issues with minors, understanding Medical Assistance in Dying (MAiD) legislation in Canada, and resolving end-of-life disputes among family members. Capacity assessment, substitute decision-maker hierarchies, guardianship law, and restraint regulations are heavily tested on RN licensing examinations. The nurse must balance patient autonomy, beneficence, and legal compliance while maintaining meticulous documentation of all decisions and communications.
