What condition does the nurse suspect when a patient involved in a motor vehicle accident arrives at the emergency department with ecchymosis behind the ears and bleeding from the ears?
Explanation & Rationale
Choice A reason: An epidural hematoma is a type of traumatic brain injury where blood accumulates between the dura mater and the skull. While it can cause severe symptoms, including headache, loss of consciousness, and neurological deficits, it does not typically present with ecchymosis behind the ears (Battle's sign) or bleeding from the ears. These signs are more indicative of a basilar skull fracture.Choice B reason: An ischemic stroke occurs when a blood clot blocks or narrows an artery leading to the brain, causing reduced blood flow and oxygen to the brain tissue. Symptoms of an ischemic stroke include sudden weakness, numbness, difficulty speaking, and vision problems. However, it does not cause ecchymosis behind the ears or bleeding from the ears, which are specific signs of a basilar skull fracture.Choice C reason: A subarachnoid hemorrhage is bleeding into the space between the brain and the tissue covering the brain (subarachnoid space). It often presents with a sudden, severe headache, nausea, vomiting, and loss of consciousness. While it is a serious condition, it does not typically cause ecchymosis behind the ears or bleeding from the ears.Choice D reason: A basilar skull fracture isThe correct answer. This type of fracture involves the base of the skull and can cause characteristic signs such as ecchymosis behind the ears (Battle's sign) and bleeding from the ears due to the proximity of the fracture to the auditory canal and other structures. These symptoms are key indicators of a basilar skull fracture and require immediate medical attention.
