Answer :
If a person chokes and becomes unresponsive, the rescuer should start CPR, prioritizing chest compressions. Abdominal thrusts are not suitable for an unresponsive individual, and the focus should be on prompt action to provide oxygen and minimize brain damage. Thus option a is correct.
If a person chokes on a foreign object and becomes unresponsive, the rescuer should immediately begin delivering CPR, starting with chest compressions after sending someone to activate the emergency response system. Trained first responders might perform both chest compressions and mouth-to-mouth breathing, but bystanders should focus on compression-only CPR.
Calling the victim's doctor or performing a blind finger sweep are not recommended actions, and abdominal thrusts, such as the Heimlich maneuver, are not appropriate for an unresponsive individual.
When dealing with choking, identifying the signs is crucial. Symptoms include the inability to speak, labored breathing with gasping or wheezing, and possibly clutching at the throat or mouth. If the person becomes unresponsive, you must act quickly to restore oxygen to the brain to minimize the risk of brain damage or death.
Remember to always seek professional training to ensure you are prepared to respond correctly in such emergencies. Thus option a is correct.
