<prompt> Excess secretion of aldosterone causes all exceptIncreased ECFVery High Na in plasmaIncreased BPNatriuresis  <response>: B i.e. Very High Na in plasma Hyperaldosteronism excess mineralocoicosteroid leads to potassium K depletion hypokalemia and sodium Na retention, usually without edema but with weakness tetany, polyuria, hypeension and hypokalemic mild metabolic alkalosisQ. Hyperaldosteronism does not cause metabolic acidossQ. And plasma Na level is elevated only slightly if at allQ because water is retained with osmolically active Na ions.
