A 45-year-old man with hypertension is diagnosed with primary hyperaldosteronism. Which of the following changes is most likely in this patient? A) Increased plasma renin activity, increased plasma K+ concentration, increased extracellular fluid volume B) Increased plasma renin activity, increased plasma K+ concentration, decreased extracellular fluid volume C) Increased plasma renin activity, decreased plasma K+ concentration, increased extracellular fluid volume D) Increased plasma renin activity, decreased plasma K+ concentration, decreased extracellular fluid volume E) Decreased plasma renin activity, decreased plasma K+ concentration, decreased extracellular fluid volume F) Decreased plasma renin activity, decreased plasma K+ concentration, increased extracellular fluid volume G) Deceased plasma renin activity, increased plasma K+ concentration, increased extracellular fluid volume Is the answer F? In primary hyperaldosteronism, one would see hypokalemia and fluid retention. The increased aldosterone production would inhibit the renin-angiotensin system.

Primary Hyper aldosteronism( MCC--> Adenoma of adrenals aka Conns syndrome)------------>Renin INDEPENDENT excessive Aldosteone production(Decreased Renin)------->Increased Na+ retention--------->IV volume and K+ excretion--------------->F
