What action should be taken if a victim is unresponsive and not breathing but has a pulse?

In the scenario described, the correct action is to begin rescue breathing because the victim is unresponsive and not breathing, yet still has a pulse. When a person is unable to breathe on their own, but maintains a heartbeat, it is crucial to provide oxygen to prevent brain damage and other complications from hypoxia (lack of oxygen).

Rescue breathing involves delivering breaths to the victim at regular intervals to ensure they receive sufficient oxygen. This is vital in situations of respiratory failure where the heart is still functioning, yet the lungs are not effectively transferring oxygen into the bloodstream.

The other options are not appropriate for this situation. Performing chest compressions is unnecessary since the victim has a pulse, indicating the heart is still beating. Initiating CPR would be incorrect in this context as CPR is indicated only when there is no pulse detected. Checking for injuries, while important in a comprehensive assessment, does not address the immediate need for oxygenation in this critical situation. Thus, focusing on providing rescue breaths is the immediate priority.
