Metabolic alkalosis is seen in-: (A) Primary mineralocoicoid excess, (B) Deficiency of mineralocoicoid, (C) Decreased acid excretion, (D) Decreased base excretion
Answer is A. Mineralocoicoid excess increases net acid excretion and may result in metabolic alkalosis, which may be worsened by associated K+ deficiency. ECFV expansion from salt retention causes hypeension. The kaliuresis persists because of mineralocoicoid excess and distal Na+ absorption causing enhanced K+ excretion, continued K+ depletion with polydipsia, inability to concentrate the urine, and polyuria.
