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

Bruising around the eyes, often referred to as "raccoon eyes," is indeed a typical sign of a skull fracture. This characteristic bruising results from the pooling of blood in the tissues surrounding the eyes, which can occur when there is trauma to the skull that disrupts the delicate blood vessels in the area. The presence of such discoloration can suggest a fracture of the base of the skull, signifying the severity of the injury.

Other signs that may accompany a skull fracture include swelling, deformity of the skull, or clear fluid drainage from the nose or ears, but the mentioned bruising is a particularly identifiable external manifestation. The visibility of such symptoms can aid medical professionals in quickly assessing the extent of injury and determining necessary interventions.
