A person in cardiac arrest can be recognized primarily by the absence of a pulse and unresponsiveness. Cardiac arrest occurs when the heart stops pumping blood effectively, leading to the cessation of circulation. This results in a person becoming unresponsive and not breathing normally. Checking for a pulse and confirming the individual is unresponsive are critical steps in the assessment of a potential cardiac arrest situation.

While the other options might indicate other medical conditions, they are not definitive signs of cardiac arrest. Frequent coughing and breathing difficulties could suggest a respiratory issue; confusion and anxiety may point to various mental or physical health problems; excessive sweating and nausea are symptoms often associated with other conditions, like a heart attack or illness, rather than the clear-cut absence of pulse and responsiveness that define cardiac arrest. Understanding these signs is vital for quick and effective intervention when dealing with emergencies.
