You are caring for an elderly patient who sustained a head injury earlier today. She seems be acting confused. The patient's family members say that she is usually confused at baseline at home as well. However, you as the RN are still concerned about which of the following with this patient?

A. Subdural hematoma is correct because older adults are at high risk for subdural hematomas following head trauma, even with minor injuries. Brain atrophy in the elderly causes stretching of bridging veins, increasing the likelihood of bleeding. Symptoms can be subtle, delayed, or mistaken for baseline confusion or dementia. A change in mental status after a head injury should always prompt concern for intracranial bleeding, making this the priority and most serious potential complication. B. Delirium related to being in the hospital is incorrect because although hospitalization can cause delirium in elderly patients, this explanation should not be assumed when there is a recent head injury. Intracranial bleeding must be ruled out first, as it is life-threatening and requires urgent intervention. C. Diabetes is incorrect because there is no information provided indicating hypoglycemia or hyperglycemia, and diabetes would not be the most immediate concern related to confusion following a head injury. While glucose abnormalities can cause altered mental status, they are not the highest-priority concern in this scenario. D. Scalp laceration is incorrect because scalp injuries can cause significant bleeding but do not typically cause changes in mental status. The presence of confusion after head trauma raises concern for deeper intracranial injury rather than a superficial wound.
