Which statement best reflects the purpose of advance directives?

• A. They provide patient preferences for life-sustaining treatment.
• B. They automatically compel clinicians to withhold treatment.
• C. They have no legal or ethical significance.
• D. They only apply to outpatient care.

Answer: (A)

Advance directives document patient preferences for life-sustaining treatment so decisions about care can reflect what the patient would want when they cannot speak for themselves. They usually cover choices about resuscitation, mechanical ventilation, artificial nutrition and hydration, and may name a health care proxy to make decisions if needed. The key point is honoring the patient’s autonomy and values by guiding clinicians and surrogates to provide care that aligns with those wishes, reducing uncertainty and family distress during difficult times. They are not a blanket rule that requires withholding treatment; they are preferences that clinicians interpret within the medical situation and legal framework. They do have legal and ethical significance and apply across all care settings, not just outpatient care.
