62. A 24-year-old man comes to the physician for a follow-up examination. He has persistent hypertension despite treatment with clonidine. His pulse is 70/min, and blood pressure is 140/100 mm Hg. Physical examination shows no other abnormalities. Radiographic imaging shows a narrowing of the aorta at the level of the diaphragm, and a fourfold increase in plasma renin activity. Which of the following is the most likely cause of the increased plasma renin activity in this patient? A) Decreased renal perfusion pressure B) Hyperaldosteronism C) Hypernatremia D) Hyponatremia E) Increased renal sympathetic activity 00000
