Stage 1 intracranial hypertension is caused by the:
A) Loss of autoregulation that normally maintains constant blood flow during changes in cerebral perfusion pressure
B) Displacement of cerebrospinal fluid, followed by compression of the cerebral venous system
C) Vasoconstriction of the cerebral arterial system with reciprocal increase in systemic blood pressure
D) Compression of the medulla oblongata in the brainstem by herniation of the cerebral cortex

Question

Quizplus · Accepted Answer

If intracranial pressure remains high after cerebrospinal fluid (CSF)displacement out of the cranial vault,then cerebral blood volume is altered,resulting in stage 1 intracranial hypertension.Vasoconstriction and external compression of the venous system occur in an attempt to further decrease the intracranial pressure.None of the remaining options accurately describe the cause of stage 1 intracranial hypertension.
