Emergency Medical Technician (EMT) Practice Test

Which symptoms are associated with head trauma level 1?

1. decerebrate posturing

2. cheyne-stokes breathing

3. pupils dilated and non-reactive

4. decorticate posturing

The correct answer is: decorticate posturing

The symptoms associated with level 1 head trauma include decorticate posturing, which is characterized by abnormal flexion of the arms, wrists, and fingers with the legs extended and internally rotated. This posturing is often a response to severe brain injury and indicates that the brain is still capable of some basic motor responses, but there is dysfunction at the level of the brain or spinal cord. It's crucial to recognize that decorticate posturing suggests that the person may still have preserved cerebral function, though they are likely exhibiting significant neurological impairment. The other symptoms mentioned, such as decerebrate posturing, cheyne-stokes breathing, and dilated and non-reactive pupils, are typically associated with more severe brain injuries or conditions that are either life-threatening or indicative of deeper unconscious states. Recognizing decorticate posturing in head trauma allows responders to assess the level of brain function and dictate an appropriate approach for treatment and transport.
