Verified step by step guidance

Understand the context: Cardiac arrest is a medical emergency where the heart stops effectively pumping blood, leading to a lack of oxygen delivery to vital organs. Immediate intervention is critical to improve survival chances.

Recall the priorities in Basic Life Support (BLS): The primary focus during cardiac arrest is the CAB sequence—Circulation, Airway, and Breathing. Effective chest compressions are the cornerstone of circulation support.

Recognize the importance of chest compressions: High-quality chest compressions ensure blood flow to the brain and heart. This is the most critical intervention in the initial moments of cardiac arrest management.

Eliminate incorrect options: Administering antibiotics is not relevant in cardiac arrest. Wound cleaning is secondary to airway and circulation management. Defibrillation should not be delayed for intravenous access, as restoring heart rhythm is time-sensitive.

Conclude with the correct principle: Early and effective chest compressions are the most important action to prioritize during cardiac arrest treatment, as they directly impact survival outcomes.
