Which of the following is a sign of a skull fracture?

A sign of a skull fracture is the presence of clear liquid or blood coming from the ears, nose, or eyes. This phenomenon often points to a serious head injury, potentially indicating that cerebrospinal fluid (CSF) is leaking due to the fracture, which can occur when there is a break in the cranial bones. The fluid can appear clear, resembling watery fluid, or if blood is involved, it may indicate more severe trauma. Prompt recognition of this sign is vital for immediate medical assessment and intervention, as it can lead to significant complications, including infections or brain injury.

Other signs listed, like bruising around the eyes, severe headache, or lack of consciousness, may also indicate a head injury but are not as definitive in confirming a skull fracture. Bruising around the eyes might suggest trauma, but it doesn’t specifically indicate a fracture. Similarly, a severe headache can result from various causes and does not pinpoint a skull fracture. Lack of consciousness indicates a serious condition, but like the others, it is not a specific indicator of a skull fracture. The presence of fluid from the ears, nose, or eyes specifically suggests a possible fracture and the risk of associated complications, making it the most indicative sign.
