What is the primary legal basis that supports a patient's right to refuse medical advice?

A. Medical malpractice prevention: Malpractice prevention relates to protecting healthcare providers from negligence claims but does not establish a patient’s right to refuse care. It is focused on provider accountability, not patient autonomy. B. Informed consent: Informed consent ensures that patients receive adequate information about the benefits, risks, and alternatives of treatment before agreeing or refusing to proceed. This legal and ethical principle upholds the patient’s right to autonomy and self-determination. C. Patient confidentiality: Confidentiality protects private health information but does not give the patient the legal right to refuse treatment. It governs how information is shared, not decision-making authority about care. D. Advance directives: Advance directives are used to communicate treatment preferences when a patient is unable to speak for themselves. While important, they do not serve as the primary legal foundation for a competent patient’s immediate right to refuse treatment.
