Define 'advance directive' and its role in patient autonomy.

• A. A legal document specifying a patient’s preferences for medical treatment when they cannot communicate.
• B. A contract with provider to guarantee care.
• C. A form that ensures always life-sustaining treatment.
• D. A document describing patient medical history.

Answer: (A)

An advance directive is a legal document that records a person’s preferences for medical treatment in case they cannot communicate or make decisions. This protects patient autonomy by ensuring that future care aligns with their values and wishes even when they’re incapacitated. It can include who will make medical decisions on the person’s behalf (a health care proxy) and what treatments are acceptable or unacceptable, such as decisions about resuscitation, life support, artificial nutrition and hydration, and comfort-focused care. It helps clinicians and families understand the patient’s desires, guiding care when the patient can’t speak for themselves and reducing uncertainty or conflict. It’s not a contract with a provider, not a guarantee of receiving life-sustaining treatment, and not simply a record of medical history. The specifics can vary by jurisdiction and directives can be updated as preferences change.
