A nurse is assessing a client who has increased intracranial pressure. The nurse should recognize that which of the following is the first sign of deteriorating neurological status?

Choice A reason : A severe, throbbing headache is a common and significant manifestation of autonomic dysreflexia. This condition is a potentially life-threatening medical emergency that can occur in individuals with spinal cord injuries, typically above the T6 level. The headache results from a sudden and severe increase in blood pressure due to an exaggerated response of the autonomic nervous system to a stimulus below the level of the injury.

Choice B reason: Hypotension, or low blood pressure, is not a manifestation of autonomic dysreflexia. In fact, the condition is characterized by hypertension, or high blood pressure, which is a critical sign that requires immediate attention to prevent complications such as stroke or seizure.

Choice C reason: Fever is not a direct manifestation of autonomic dysreflexia. While a fever may indicate an infection or other systemic issue, autonomic dysreflexia itself is specifically associated with a rapid onset of high blood pressure and other autonomic disturbances.

Choice D reason: Cyanosis of the head and neck, which refers to a bluish discoloration of the skin due to poor circulation or inadequate oxygenation of the blood, is not a typical manifestation of autonomic dysreflexia. The condition primarily causes hypertension and its associated symptoms, rather than issues with oxygenation.

Choice A reason: Papilledema, which is the swelling of the optic disc due to increased ICP, is not typically an early sign. It is usually a later manifestation because it takes time for the pressure to build up and affect the optic nerve.

Choice B reason: Restlessness can be an early sign of increased ICP. As ICP begins to rise, it can cause subtle changes in a person's level of consciousness, leading to agitation or restlessness. This is often one of the first signs that healthcare providers notice when monitoring for changes in neurological status.

Choice C reason: Projectile vomiting may occur with increased ICP, but it is not usually an early sign. It tends to occur after other symptoms such as headache and altered consciousness and is more indicative of significant pressure increases that affect the brainstem.

Choice D reason: Decorticate posturing is a severe sign of brain injury associated with increased ICP but is not an early sign. It indicates significant damage to the brain and is a late and ominous sign in the progression of increased ICP.
