Which signatures are required on a DNR to show it was complete?

• A. The person issuing the DNR and the physician executing it
• B. The nurse and the patient
• C. The administrator and the social worker
• D. The patient and the nurse

Answer: (A)

The important idea is that a DNR is a medical order that must be authorized by both the patient (or their legal surrogate) and the physician who will carry it out. The patient’s or surrogate’s signature shows consent and understanding of the decision, while the physician’s signature approves the medical appropriateness of withholding resuscitation and formally documents the order. Without the patient’s (or surrogate’s) signature, there’s no indication of consent; without the physician’s signature, there’s no official medical order to follow. Other professionals like nurses or administrators don’t authorize DNRs—they implement orders or provide care, but the final authorization rests with the patient’s consent and the physician’s signature.
