Which drug is essential for treating cardiac arrest?

• A. Buccal midazolam
• B. Oxygen
• C. Adrenaline
• D. Aspirin

Answer: (C)

Adrenaline is an essential medication for treating cardiac arrest because it functions as a powerful vasopressor that increases blood flow to vital organs during resuscitation efforts. During a cardiac arrest, the heart is unable to pump effectively, and adrenaline helps to stimulate the heart and improve circulation. It achieves this by constricting blood vessels, which increases blood pressure and enhances blood flow to the heart and brain, ultimately increasing the chances of successful resuscitation. Other medications, such as buccal midazolam, are typically used for seizure management rather than cardiac emergencies. Oxygen plays a critical role in supporting respiration and providing supplemental oxygen to patients in respiratory distress, but it is not a primary treatment for cardiac arrest itself. Aspirin is often used for its antiplatelet effects to prevent blood clots, especially in patients experiencing a heart attack, but it does not have a direct role in the emergency intervention required during a cardiac arrest.
