[|Human|] Hi, I have some question that I really want to know, hopefully you can give me the answers, thanks! 1. what color liquid leaks from the nose and is a sign of a concussion? 2.what knid of abnormal eye pupil exam is shown? 3.identify two tests that are done to diagnose a concussion?
[|AI|]  1. In a concussion, there shouldn't be any visible changes to the head. If there is fluid leaking out of the nose and its clear, it could be cerebrospinal fluid (CSF) meaning there needs to be a leak repaired or there could be a meningitis. This can happen from a cribriform plate fracture often seen in frontal head injuries.2. There also should not be an abnormal pupil exam. If there is one, you need to go to the ER immediately.3. To diagnose concussion, it is basically any head injury that causes an alteration in mental status. There can be tests done, but they are usually done to rule out something else like a contusion (blood in the brain) or neck fracture for example.
