Step-by-step explanation:
The statement that is not true about CPR is option d: you should only perform CPR on someone who is awake and breathing.
CPR, or cardiopulmonary resuscitation, is an emergency procedure performed when the heart stops beating. It involves providing continuous oxygen and blood flow to the heart and brain in order to keep someone alive. Immediate CPR greatly increases the chances of a victim's survival.
It is important to note that CPR should be performed on individuals who are unresponsive and not breathing or only gasping. If someone is awake and breathing, CPR is not needed.
