A nurse is caring for a client admitted with meningitis.
The student nurse asks, “I know that the client has a lot of edema in the brain, but what causes it?” Which of the following responses from the nurse best answers the student’s querry

Choice A rationale
Bruising over the mastoid process, also known as Battle’s sign, is a classic clinical sign of a basilar skull fracture.
Choice B rationale
Pooling of blood and edema around the eyes, or ‘raccoon eyes’, is another sign of a basilar skull fracture.
Choice C rationale
The ability to recall how the injury occurred is not directly related to the presence of a basilar skull fracture. Memory loss or confusion could be symptoms of a traumatic brain injury, but they are not specific to a basilar skull fracture.
Choice D rationale
Chvostek’s sign is a clinical sign of hypocalcemia, not a basilar skull fracture

Choice A rationale
Vision loss and depression are not typically symptoms of a mild traumatic brain injury (TBI). Vision loss could be a symptom of a more severe TBI or other neurological conditions.
Depression, while it can occur following a TBI, is not a direct symptom of the injury itself but rather a common psychological reaction to the changes and challenges that a person may face following the injury.
Choice B rationale

Seizures and weakness in the extremities can be symptoms of a TBI, but they are more commonly associated with moderate to severe TBIs. Mild TBIs do not typically cause seizures or weakness in the extremities.
Choice C rationale
Persistent headache can be a symptom of a mild TBI. However, aggressive behavior, while it can occur following a TBI, is not a direct symptom of the injury itself but rather a possible psychological reaction to the changes and challenges that a person may face following the injury.
Choice D rationale
Headache and confusion are common symptoms of a mild TBI. After a mild TBI, individuals may experience a headache or a feeling of pressure in the head. They may also experience confusion or feel as if in a fog.
