What does a DNR order signify?

A Do Not Resuscitate (DNR) order signifies a patient's wish to forgo resuscitative measures in the event of cardiac arrest or respiratory failure. It is an advance directive that communicates a patient’s preferences regarding their care in life-threatening situations where they may not be able to express their wishes.

By designating instructions written in advance of an event, a DNR order ensures that healthcare providers are aware of the patient's desires prior to an emergency, thereby guiding treatment decisions accordingly. This proactive measure allows for respecting the patient's autonomy and aligning medical interventions with their values and wishes regarding end-of-life care.

In this context, it's clear why the other options do not fit the definition of a DNR order. Providing all possible interventions contradicts the essence of a DNR. A DNR is not a legal document for transferring care, as it does not pertain to the transfer of responsibilities but rather focuses on the type of medical intervention during a specific medical emergency. Lastly, a DNR is not limited to instructions for mental health care, as it primarily concerns physical medical interventions and resuscitation efforts.
