Which of the following best describes a living will?

A living will is best described as a written statement of desired medical treatments. This legal document specifies the types of medical care and interventions an individual wishes to receive or avoid in the event that they become unable to communicate their preferences due to illness or incapacitation. The primary purpose of a living will is to ensure that a person's healthcare choices are respected and adhered to, even when they are unable to articulate those choices themselves.

This document typically addresses end-of-life care, such as the use of life-sustaining treatment or resuscitation measures, allowing individuals to maintain control over their medical decisions during critical times. This helps alleviate the burden on family members and healthcare providers by providing clear guidance on the individual's wishes.

The other options do not accurately define a living will. A document detailing one's medical history refers to a medical record, while a record of healthcare provider interactions would pertain to documentation of clinical visits and treatments received. A plan for caregiving in assisted living focuses on the day-to-day management of care in such facilities and does not encompass the medical treatment decisions outlined in a living will.
