On arrival to a scene with a patient in cardiac arrest and no visible DNR, what should you do?

• A. Initiate CPR
• B. Withhold CPR until proof of DNR
• C. Call for police to verify DNR
• D. Continue observation only

Answer: (A)

In cardiac arrest, the default is to start life-saving treatment immediately if there is no clearly visible DNR. In emergencies, there is an assumption of consent to provide CPR and related resuscitation unless a valid DNR is readily accessible. Delaying CPR to confirm a DNR wastes precious time and lowers the chance of survival, so the best action is to begin chest compressions right away and summon help, while using an AED as soon as it’s available. If a legitimate DNR is later found or verified, you would honor it and stop resuscitation according to that order, but in the absence of visible documentation, active resuscitation is indicated.
