What should be administered to a person experiencing stroke symptoms while waiting for emergency services?

When dealing with a person experiencing stroke symptoms, administering oxygen is crucial as it helps ensure that the brain receives adequate oxygenation during this critical time. Stroke symptoms can lead to impaired blood flow and oxygen delivery to the brain, which can result in brain cell death. By providing oxygen, you can help maintain the availability of this vital resource to the brain and potentially minimize damage until emergency services arrive.

It's important to monitor the individual's vital signs and comfort level, and oxygen can alleviate symptoms of hypoxia and support overall brain health. While other options may have specific applications in medical practice, they do not serve the immediate need for oxygenation during a stroke incident.
