Multiple Choice

How does acute unilateral renal obstruction predispose people to hypertension?

• A)The hydronephrosis that develops prevents any further blood from entering the kidneys, which results in an increase in the systemic blood volume.
• B)The reduced perfusion of the affected kidney activates the renin-angiotensin-aldosterone system, which causes constriction of peripheral arterioles.
• C)The pain resulting from the renal obstruction stimulates the autonomic nervous system, causing vasoconstriction of peripheral arterioles.
• D)The renal obstruction prevents the usual loss of sodium through the urine, causing retention of sodium and water, which increases blood volume.
