A more thorough explanation:

Definition: A DNR order, also known as a DO-NOT-RESUSCITATE ORDER, is a medical order that instructs healthcare providers not to perform cardiopulmonary resuscitation (CPR) if a patient's heart stops or if they stop breathing.

Example: If a patient has a DNR order in place, and they experience cardiac arrest, healthcare providers will not perform CPR. Instead, they will focus on providing comfort care and managing the patient's symptoms.

Explanation: A DNR order is a legal document that is signed by a patient or their legal representative. It is important for patients to discuss their wishes with their healthcare providers and loved ones to ensure that their wishes are respected in the event of a medical emergency. The example illustrates how a DNR order impacts the care a patient receives in the event of cardiac arrest.
