Basic life support is often needed for victims of

• A. Drowning, burns, or fainting
• B. Fractures, bleeding, or shock
• C. Choking, drowning, or heart attack
• D. Heat exhaustion, dehydration, or sprains

Answer: (C)

Basic life support is needed in emergencies where breathing or circulation may be failing. When someone is choking, the airway can become completely blocked, so immediate actions to restore ventilation are essential—this may start with clearing the obstruction if possible, then CPR if the person becomes unresponsive. Drowning removes oxygen from the lungs, leading to respiratory arrest; rescue breaths and chest compressions are key parts of BLS while waiting for advanced care. A heart attack can progress to cardiac arrest; early recognition and initiating CPR with an AED when available are crucial life-saving steps. These situations show why BLS focuses on airway, breathing, and circulation because they pose the greatest risk of death if not addressed promptly. Other conditions like fractures, bleeding, or shock may require urgent care, but they aren’t the classic scenarios where immediate CPR and AED use are routinely indicated; heat-related illnesses, dehydration, or sprains are typically non–life-threatening unless they progress to shock or arrest.
