The most essential element in the administration of CPR is __________.
• CPR (Cardiopulmonary Resuscitation) basic purpose: what problem is it meant to correct first? • The importance of time when the heart and/or breathing has stopped • Difference between supporting measures (oxygen, shock treatment, equipment) vs. the core life-saving action
• Ask yourself: in the first critical minutes after a person’s heart or breathing stops, what factor most affects whether the brain survives? • Which option deals with something you absolutely can start immediately, even with no special gear available? • Which choices describe helpful but secondary treatments rather than the core, urgent action of CPR itself?
• Verify which choice focuses on how quickly life support is started after collapse. • Check which answers require special equipment or additional supplies—those are usually not the “most essential” in an emergency start of CPR. • Confirm you are thinking about immediate survival of heart/brain, not long‑term care or treatment of other conditions.
