Which of the following is NOT a part of advanced directives?

The medical history form is not considered a part of advanced directives. Advanced directives are specific legal documents that provide instructions regarding an individual's healthcare preferences in the event they become unable to communicate their wishes due to illness or incapacity.

A living will outlines the types of medical treatments a person does or does not want at the end of life, while a durable power of attorney for healthcare allows a designated person to make healthcare decisions on someone’s behalf when they cannot do so themselves. A healthcare proxy is a similar concept, where an individual designates someone to make medical decisions for them if they are incapacitated.

In contrast, a medical history form primarily documents a patient's medical background, current conditions, medications, and allergies, which is essential for providing care but does not dictate treatment preferences or decision-making authority in the context of advanced directives. Therefore, the correct identification of the medical history form as not being part of advanced directives furthers clarity in understanding the distinct roles these documents play in healthcare decision-making.
