A young adult client involved in a minor motor vehicle collision three weeks ago reports having a headache, blurred vision, vertigo, and nausea. The client's vital signs are within normal limits, and a nutrition history reveals that the client is eating very little because of being concerned about paying for car repairs. Priority nursing care should be based on which nursing problem?

A. The client's symptoms of headache, blurred vision, vertigo, and nausea, even without abnormal vital signs, are suggestive of potential neurological complications from a head injury, such as increased intracranial pressure (ICP). This requires immediate attention and evaluation. B. While the client is experiencing discomfort, it is secondary to the potential neurological issue. C. The client's nutritional status is a concern, but it is not the priority at this time, given the potential neurological implications of the client's symptoms. D. While the client's anxiety is understandable, it is not the primary concern given the more immediate health risk.
