Which of the following is an example of advance directives?

A durable power of attorney for healthcare is a legal document that allows a person to appoint another individual to make healthcare decisions on their behalf if they become unable to make those decisions themselves. This is a key component of advance directives, which are intended to ensure that a person’s healthcare preferences are respected in situations where they cannot communicate those wishes directly.

Advance directives include a range of documents that outline specific healthcare preferences and instructions, and the durable power of attorney for healthcare is particularly important because it designates a trusted individual to advocate for the patient's wishes regarding medical treatment and end-of-life care. Thus, this choice directly aligns with the definition of advance directives as they relate to pre-established healthcare planning and decision-making authority.

The other options involve important aspects of patient care but do not qualify as advance directives. A medical history questionnaire is more about collecting past health information rather than expressing future healthcare wishes. A list of current medications provides information about what a patient is currently taking but does not capture their preferences or decisions regarding care in the future. Lastly, a document detailing a patient's insurance coverage pertains to financial aspects of healthcare rather than the patient's wishes for their medical treatment or end-of-life decisions.
