This document discusses confidentiality and informed consent in nursing. It defines confidentiality as protecting personal patient information and informed consent as a process of getting permission for healthcare procedures by educating patients on risks, benefits, and alternatives. The importance of confidentiality is to protect privacy, reputation, and prevent misuse of information, while informed consent creates trust, respects autonomy, and ensures understanding. Ethical and legal elements of informed consent include providing information, assessing patient competence and autonomy. Nurses' roles are to understand legal guidelines and facilitate informed consent processes, especially in special circumstances.
