Hypertension with hypokalemia and metabolic alkalosis  
A 41-year-old man with hypertension since age 32 has hypokalemia, metabolic alkalosis, and adrenal nodule. Renin and aldosterone levels are not diagnostic for primary hyperaldosteronism, but his blood pressure responded to the addition of an aldosterone receptor antagonist (ARA). How far do we go in the work-up or do we just continue the ARA? What do you think?
