What is a noticeable sign of a blockage in an adult client with hydrocephalus?

In the context of hydrocephalus, which involves an accumulation of cerebrospinal fluid (CSF) in the brain, a noticeable sign of a blockage is often the enlargement or abnormal growth of the head, particularly in individuals who are still developing. This is primarily because the increased pressure from the fluid cannot be released, leading to an expansion of the cranial cavity. In adults, however, the skull is already fused and will not visibly grow, but the accumulation of fluid can lead to other symptoms due to increased intracranial pressure.

Although growth of the head is typically associated with pediatric cases, what is critical to note is that in response to blockage, patients may indeed exhibit various symptoms, such as severe headaches due to the pressure on brain tissues and increased intracranial pressure. However, if the question is focused solely on the observable physical sign related to hydrocephalus specifically rather than symptoms, the point regarding head growth aligns more closely with conditions seen in developing individuals.

In adults, other symptoms like headaches, loss of coordination, or changes in vision may be more prevalent but do not indicate a specific physical change like growth would. Therefore, while option A reflects something observable in patients with hydrocephalus, it is essential to understand
