A nurse is admitting a young adult client who has suspected bacterial meningitis. The nurse should closely monitor the client for increased intracranial pressure (ICP) as indicated by which of the following findings?

Choice A reason: Nuchal rigidity is a hallmark of bacterial meningitis due to meningeal inflammation but is not a direct indicator of increased intracranial pressure. It reflects irritation of the meninges, causing neck stiffness. While common in meningitis, it does not specifically signal rising ICP, which requires other neurological signs. Choice B reason: Widened pulse pressure (e.g., high systolic, low diastolic) is a key indicator of increased intracranial pressure in bacterial meningitis, often part of Cushing’s triad (with bradycardia and irregular breathing). It results from cerebral compression affecting autonomic regulation, signaling a critical need for intervention to reduce ICP. Choice C reason: Elevated temperature is common in bacterial meningitis due to infection but is not a specific indicator of increased intracranial pressure. Fever reflects the body’s immune response to bacterial invasion, not the mechanical pressure effects on brain tissue that characterize rising ICP in this condition. Choice D reason: Pupils reactive to light indicate normal cranial nerve function and are not a sign of increased intracranial pressure. Fixed or dilated pupils suggest ICP elevation due to compression of the oculomotor nerve. Reactive pupils are reassuring but do not rule out early ICP changes.
