Which of the following is NOT a common sign of elevated ICP?

Improved coordination and balance is not a common sign of elevated intracranial pressure (ICP). When ICP increases, the brain and surrounding structures are affected, leading to a range of symptoms. Typically, signs of elevated ICP include neurological changes such as a sudden alteration in the level of consciousness due to pressure on the brain. Pupil dilation may occur as a result of pressure affecting cranial nerves that control eye function. Additionally, changes in respiratory rate can manifest due to the brainstem's involvement with increased pressure, which often leads to irregular breathing patterns.

Conversely, improved coordination and balance would not be expected in the context of elevated ICP. In fact, elevated ICP generally results in impaired neurological function, including compromise in motor skills, coordination, and overall balance. Therefore, this answer accurately identifies a symptom that does not align with the clinical manifestations associated with increased intracranial pressure.
