What does a notation of DNR on a patient's chart indicate?

A notation of DNR, which stands for "Do Not Resuscitate," clearly indicates that a patient has chosen to forgo resuscitation efforts in the event of cardiac or respiratory failure. This means that if the patient's heart stops beating or they stop breathing, medical staff will not perform CPR (cardiopulmonary resuscitation) or employ other resuscitation techniques such as intubation or defibrillation. This decision is typically made by the patient or their legal representative after discussions with healthcare providers about the patient's health status and wishes regarding end-of-life care.

Understanding this term is critical for healthcare professionals, as it outlines the patient's preferences regarding life-sustaining treatments. In practice, respecting a DNR order is a part of honoring the patient's autonomy and right to make informed choices about their healthcare and life. The other answer choices do not pertain to the specific directive that a DNR notation represents regarding cardiopulmonary resuscitation and life support interventions.
