What should be done first if a patient becomes unresponsive during ACLS procedures?

• A. Start immediate CPR
• B. Check for breathing and pulse
• C. Call a code status
• D. Prepare for intubation

Answer: (B)

In the scenario where a patient becomes unresponsive during ACLS procedures, the first step should be to check for breathing and pulse. This action is crucial because it helps determine the patient's condition and appropriate next steps for intervention. If the patient is not breathing or does not have a detectable pulse, immediate CPR should be initiated. Conversely, if there are signs of life such as breathing or a pulse, the focus may shift to supporting the patient, identifying causes of the unresponsiveness, and providing necessary care.

By verifying the patient's breathing and pulse, you can accurately assess the need for advanced life support measures, such as starting CPR or calling for additional help, depending on the situation. It is essential to have this foundational assessment before taking further actions like preparing for intubation or calling a code. This approach follows the algorithmic steps established in ACLS protocols, which emphasize assessment before intervention.
