Emergency Medical Responder Practice Exam

A common sign of a head injury includes confusion, loss of consciousness, or a severe headache. These symptoms indicate that the brain may have been affected and signal a potentially serious condition. Confusion often arises when the brain is unable to function properly due to trauma, while loss of consciousness may indicate a more severe injury or concussion. Severe headaches can be a direct result of trauma to the head or the effects of swelling or pressure within the skull.

The other symptoms listed do not typically correlate with head injuries. Increased heart rate can occur in response to various situations but is not specific to head trauma. Coughing and sneezing are related to respiratory issues rather than head injuries, while fever and chills are more associated with infections or systemic illness rather than trauma to the head. Therefore, the combination of confusion, loss of consciousness, and severe headache is a clear indicator of a potential head injury and should prompt immediate evaluation and care.
