Which of the following can lead to death if physical management is not executed properly?

The reason cardiac arrest can lead to death if physical management is not executed properly is that immediate and effective intervention is crucial during such an event. Cardiac arrest occurs when the heart suddenly stops beating, preventing blood from flowing to the brain and other vital organs. If physical management or appropriate emergency services are not deployed quickly, the individual may suffer irreversible brain damage or death due to the lack of oxygenated blood.

Swift actions such as cardiopulmonary resuscitation (CPR) or the use of an automated external defibrillator (AED) can significantly increase the chances of survival and recovery. In contrast, while dehydration, distraction, and overexertion can lead to serious health issues, they do not have the same immediate life-threatening nature as cardiac arrest and typically allow for more time to respond effectively.
