What should you NOT do when managing a significant head injury?

When managing a significant head injury, allowing the person to walk to a medical facility is not appropriate due to the risk of exacerbating their condition. Head injuries can lead to various complications, including loss of consciousness, disorientation, or worsening symptoms. Moving the individual, especially walking, can increase the risk of secondary injuries or complications, such as a fall or worsening of the head injury, which could lead to serious outcomes.

In contrast, monitoring the person's responsiveness, providing first aid and stabilizing the head, and activating EMS for evaluation are critical steps in ensuring the individual's safety and facilitating appropriate medical care. These actions help in assessing the severity of the injury, preventing further harm, and ensuring that professional medical personnel attend to the injury promptly.
