An urgent care nurse practitioner comes in to examine his patient, a 77-year-old woman who was brought in by her family for altered mental status. He notes that the patient appears restless and does not know where she is. Upon further assessment, he notes that her pupils are sluggish to react to light and are unequal in size. She is unable to sit up at the side of the bed and her blood pressure is 190/88 mm Hg. Which of the following does the NP suspect?

Choice A reason: Ischemic stroke can present with altered mental status and neurological deficits, but unequal pupils and inability to sit up suggest a more diffuse pressure effect rather than a focal stroke. Choice B reason: This is correct. Signs such as altered mental status, unequal and sluggish pupils, restlessness, inability to sit upright, and severely elevated blood pressure are classic indications of increased intracranial pressure. The high BP is a compensatory mechanism to maintain cerebral perfusion (Cushing’s triad may also be observed in severe cases). Choice C reason: Myocardial infarction primarily presents with chest pain, shortness of breath, diaphoresis, and sometimes altered mental status if complicated by cardiogenic shock, but it does not typically cause unequal pupils or inability to sit upright. Choice D reason: A cerebral aneurysm rupture may cause sudden severe headache and neurological deficits, but unequal pupils and progressive confusion are more characteristic of increased intracranial pressure from hemorrhage or mass effect.
