Question

Which of the following does not cause increased intracranial pressure?

1) Brain tumor
2) Cerebral edema
3) Hypotension
4) Hydrocephalus

Answer 1

Hypotension does not cause increased intracranial pressure, unlike brain tumors, cerebral edema, and hydrocephalus.

Step-by-step explanation:

The correct answer is 3) Hypotension.

Increased intracranial pressure refers to a condition where there is excessive pressure inside the skull. This can occur due to various reasons, including brain tumors, cerebral edema, and hydrocephalus. However, hypotension, which is low blood pressure, does not cause increased intracranial pressure.

When blood pressure is low, there is a decrease in the force exerted on the blood vessels, which can lead to reduced perfusion and oxygen supply to the brain. This can cause symptoms like dizziness, fainting, and confusion, but it does not result in increased pressure within the cranial vault.
