Which symptom would suggest increased intracranial pressure (ICP) in a school-aged child?

Vomiting is a significant symptom that can suggest increased intracranial pressure (ICP) in a school-aged child. Typically, this form of vomiting is characterized by being projectile and may occur without any preceding nausea. In the context of increased ICP, it is often related to irritation of the brain and its protective layers, or it could be due to pressure on the brain structures that regulate the vomiting center in the medulla.

Recognizing vomiting as a potential indicator of ICP is crucial because it can signal conditions such as head trauma, tumors, or infections like meningitis, which require prompt medical attention. The presence of such symptoms underscores the need for further evaluation to address the underlying cause and manage the child's condition effectively.

In contrast, high-pitched crying is generally more indicative of distress in infants rather than a clear sign of ICP in school-aged children. Increased appetite does not correlate with ICP and would be seen in different contexts, such as recovery from illness. Loss of coordination could suggest neurological issues, but it is less directly associated with the classic signs of increased ICP than vomiting.
