In metabolic alkalosis, there is which of the following?: (A) Gain in fixed acid, (B) Loss of base, (C) Hyperkalemia, (D) Rise in base excess
Answer is D. In metabolic alkalosis, there may be a loss of fixed acids or excess of base. It is associated with hypokalemia because of renal conservation of H+ ions and urinary potassium loss. Loss of hydrochloric acid as seen in vomiting in patients with pyloric obstruction results in hypochloremic, hypokalemic, metabolic alkalosis.
