What does a Do-Not-Resuscitate (DNR) order signify?

• A. CPR should be performed immediately in all situations.
• B. The patient must receive full resuscitation measures regardless of wishes.
• C. CPR should be performed only if the patient explicitly requests it.
• D. Do-not-resuscitate; CPR should not be performed if the patient’s heart stops or they stop breathing.

Answer: (D)

Do-not-resuscitate is an instruction that reflects a patient’s wish not to have CPR attempted if their heart stops or they stop breathing. CPR includes chest compressions, defibrillation, advanced airway support, and medications used during a cardiac or respiratory arrest. When a DNR is in place, medical teams honor that choice and do not start CPR, while other treatments and comfort measures can continue unless the order specifies otherwise. A DNR is based on the patient’s values, prognosis, or an advance directive, and it can be updated or revoked as circumstances or preferences change. Without a DNR, healthcare providers would generally proceed with resuscitation efforts if a person arrests, whereas the other scenarios described conflict with how a DNR is meant to function.
