Which of the following is a presentation of PVD affecting the kidneys?

Explanation:
Renovascular hypertension is the key idea. When peripheral vascular disease involves the renal arteries, the kidney detects reduced blood flow and releases renin. That activates the renin-angiotensin-aldosterone system, leading to angiotensin II–mediated vasoconstriction and aldosterone-driven sodium and water retention. The result is an increase in systemic blood pressure, so hypertension is the presentation you’d expect with PVD affecting the kidneys. Hypotension wouldn’t fit this mechanism, and low BUN or elevated liver enzymes don’t reflect renovascular kidney involvement.
