Which symptom indicates a cardiac arrest?

• A. Weakness or paralysis
• B. No response and no breathing
• C. Severe headache
• D. Severe confusion

Answer: (B)

The presence of no response and no breathing is a critical indicator of cardiac arrest. When a person is in cardiac arrest, their heart has stopped pumping effectively, leading to a cessation of blood flow. This results in the victim being unresponsive, meaning they do not react to stimuli such as touch or verbal commands. Additionally, the absence of breathing confirms that the individual is not able to maintain essential respiratory functions, which further supports the diagnosis of cardiac arrest. Recognizing these symptoms is crucial since immediate intervention, such as performing cardiopulmonary resuscitation (CPR) or using an automated external defibrillator (AED), can be lifesaving by providing necessary circulation and oxygen to vital organs until professional medical help arrives.
