The ethical principle of Autonomy emphasizes a patient's right to make informed decisions about their own healthcare. It respects the individual's capacity to understand information, weigh options, and choose a course of action based on personal values and preferences. Autonomy is fundamental in ensuring patients are actively involved in their treatment plans, promoting respect for their independence and dignity. This principle guides informed consent and shared decision-making processes in clinical practice.
