What document outlines a patient’s wishes for medical treatment?

The correct choice identifies the advance directive or living will as the document that outlines a patient's wishes regarding medical treatment. An advance directive is a legal document that provides individuals the opportunity to specify their preferences for medical care, particularly in situations where they may be unable to communicate their wishes themselves, such as during a serious illness or end-of-life scenario. It typically includes instructions about types of treatments the patient does or does not want, such as resuscitation or life-sustaining measures. This empowers patients by ensuring their choices about care are respected and followed.

The other choices serve different purposes and do not reflect a patient's specific treatment preferences. For instance, a patient consent form is primarily focused on obtaining permission for specific medical procedures or treatments and does not encompass broader desires for care in various situations. A medical record chart is more of a historical account of a patient's health, treatments, and progress rather than a directive about future preferences. Lastly, a discharge summary summarizes a patient's hospital stay, treatment received, and instructions for care post-discharge, rather than detailing their medical treatment preferences. Hence, the advance directive or living will is the most relevant document for conveying a patient's wishes for medical treatment.
