A 64-year-old man presents to the emergency department after a motor vehicle crash and receives a CT of the abdomen that shows a finding of a unilateral mass in the left adrenal gland. He is unharmed from the accident, feels well, and has never smoked. His blood pressure is 155/90 mm Hg, deep tendon reflexes are 3/4, and muscle strength is 4/5. Laboratory studies show:
Na+: 150 mEq/L ; K+: 3.0 mEq/L ; Cl−: 105 mEq/L;
HCO3−: 36 mEq/L
Plasma renin activity is also decreased. Which of the following is most likely to be increased?
(A) Aldosterone
(B) Anion gap
(C) Carcinoembryonic antigen
(D) Prostate-specific antigen
(E) Troponin
