For a DNR (Do Not Resuscitate) order to be valid, it is essential that there is patient consent and a physician's signature. This is because a DNR order involves a directive from the patient, indicating their wish not to receive CPR or other resuscitative measures in the event of cardiac or respiratory arrest.

The process requires that the patient (if they are able) or their legal representative must communicate their wishes, and a qualified physician must put these wishes into writing. The physician's signature serves as a confirmation that the order has been properly discussed and understood, ensuring that the decision aligns with the patient's medical condition and care goals.

In contrast, other options, such as requiring a witness from the family or including documentation in the patient's discharge summary, do not meet the legal and ethical standards necessary for a DNR order. Additionally, a legal affidavit is not required for this type of medical directive. Therefore, the combination of patient consent and a physician's signature is crucial for the validity of a DNR order.
