Which of the following emergency drugs should be administered during a stroke?

The administration of oxygen during a stroke is critical because it helps to ensure that the brain and other vital organs receive an adequate supply of oxygen. Stroke can lead to decreased blood flow and oxygen delivery to the brain, resulting in damage. By providing supplemental oxygen, you effectively support the body's needs during this critical time.

Oxygen therapy is especially important in the context of a stroke, as hypoxia (low oxygen levels) can exacerbate brain injury. Ensuring that the patient has sufficient oxygenation may help minimize brain ischemia and improve outcomes.

In situations involving strokes, other medications like adrenaline, aspirin, and nitroglycerin may not be appropriate as first-line treatments. Adrenaline is usually reserved for cardiac arrest situations, while aspirin can be used later for certain types of strokes (particularly ischemic) but is not administered immediately in an acute setting. Nitroglycerin is commonly used for heart-related issues, such as angina or heart failure, rather than strokes.
