B. Hypervolemia and hyperthermia
C. Hypovolemia and hypothermia
D. Hydrocephalous and infection

Answer 1

The major sources of intracranial hypertension after craniocerebral trauma are cerebral edema and expanding lesions, both of which can increase pressure within the skull and lead to brain damage.

Step-by-step explanation:

The major sources of intracranial hypertension after craniocerebral trauma are cerebral edema and expanding lesions. Cerebral edema is a form of swelling that results when fluid accumulates in the tissues of the brain, often triggered by an injury, such as hemorrhagic stroke, which is described as bleeding into the brain because of a damaged blood vessel. This leads to the accumulation of blood in the cranial vault, which exerts physical pressure on the brain tissue, causing loss of function and potentially further damage to the blood-brain barrier, increasing the edema.

Expanding lesions, such as hematomas or contusions, also contribute to increased intracranial pressure by occupying space within the skull and thus putting pressure on the surrounding brain tissue. Inflammation due to infections like meningitis or encephalitis can also cause intracranial pressure, but these are not primarily associated with direct craniocerebral trauma.
