hypotension
reduced blood volume at the glomerulus
hypertension
hemodialysis
increased blood volume at the glomerulus

Explanation:

Pre - renal acute renal failure is caused by a decrease in blood flow to the kidneys. Hypotension (low blood pressure) can lead to reduced blood flow to the kidneys. Reduced blood volume at the glomerulus (which is part of the nephron in the kidney and is involved in filtration) also indicates a decrease in the blood supply to the kidney, which is characteristic of pre - renal failure. Hypertension (high blood pressure) is more likely to be associated with other types of kidney problems (such as hypertensive nephropathy which can be a chronic condition and not pre - renal acute failure). Hemodialysis is a treatment for renal failure, not a cause. Increased blood volume at the glomerulus would not be a cause of pre - renal failure (which is due to decreased blood supply).

Answer:

hypotension, reduced blood volume at the glomerulus
