Which trauma scenario is listed as a DOA criterion?

• A. Blunt trauma with stable vitals
• B. Blunt or penetrating trauma with injuries incompatible with life
• C. Submersion 30 min
• D. Lividity

Answer: (B)

When trauma is so severe that life cannot be sustained, resuscitation is not attempted. That clear, objective situation is the DOA criterion: blunt or penetrating trauma with injuries incompatible with life. If the injuries are catastrophic enough that return of spontaneous circulation or meaningful life cannot be achieved, declaring DOA and withholding resuscitation is appropriate.

The other scenarios don’t meet that definitive criterion. Blunt trauma with stable vitals means the patient is alive and resuscitation should be pursued. A submersion time of 30 minutes is a context that may require rapid assessment and can still have potential for salvage, depending on other signs and circumstances. Lividity is a sign that death has occurred, but in isolation it isn’t the primary criterion used to declare DOA in all protocols, and it’s typically considered alongside other clinical findings.
