She takes lisinopril for hypertension. Her temperature is 36.5°C (97.7°F), pulse is 98/min, and blood pressure is 149/90 mm Hg. The abdomen is soft, and there is mild tenderness to palpation with no guarding or rebound. Laboratory studies show an increased urine 5-hydroxyindoleacetic acid concentration. Further evaluation of this patient will most likely show which of the following?   (A) Achlorhydria   (B) Adrenal medullary mass   (C) Multiple peptic ulcers   (D) Pulmonic valve stenosis
