Which pathological change is most typical of severe hypertension?

Intracerebral hemorrhage

Hypertensive heart disease

Hyperplastic arteriolosclerosis (correct)

Nephron loss and chronic renal failure

In malignant hypertension, the vascular changes are accompanied by which of the following?

Myocyte hypertrophy and cardiac dilation

Dissecting aneurysm of the aorta

Exacerbation of hypertension

Fibrinoid deposits and vessel wall necrosis (correct)

How does nephron loss contribute to the progression of hypertension?

It causes intracerebral hemorrhage and subarachnoid hemorrhage

It results in myocyte hypertrophy and cardiac dilation
