What does the term DNR represent in resuscitation efforts?

The term DNR stands for "Do Not Resuscitate," which is a medical order indicating that a person does not want to receive cardiopulmonary resuscitation (CPR) or other life-prolonging measures in the event of cardiac arrest or respiratory failure. This directive is essential in medical contexts, as it ensures that a patient's wishes regarding end-of-life care are respected.

Having a DNR in place allows healthcare providers to understand a patient's preferences clearly and abstain from performing invasive procedures that would conflict with those wishes. The DNR decision is often made after discussions between patients, their families, and healthcare providers, particularly in cases where patients face terminal conditions where resuscitation may not lead to a meaningful recovery.

In contrast, the other terms presented do not accurately capture the intent behind DNR. For example, "Do Not Refuse" and "Do Not Respond" imply an action towards assistance or intervention, which contradicts the purpose of a DNR. "Do Not Revive" does not accurately reflect the medical terminology used, as it suggests a refusal of revival in a more vague sense rather than the specific context of not performing resuscitation techniques.
