How does the loss of chloride during vomiting cause metabolic alkalosis?
A)Loss of chloride stimulates the release of aldosterone, which causes the retained sodium to bind with the chloride.
B)Loss of chloride causes hydrogen to move into the cell and exchange with potassium to maintain cation balance.
C)Loss of chloride causes retention of bicarbonate to maintain the anion balance.
D)Loss of chloride causes hypoventilation to compensate for the metabolic alkalosis.

Question

Quizplus · Accepted Answer

When acid loss is caused by vomiting with depletion of ECF and chloride (hypochloremic metabolic alkalosis), renal compensation is not very effective because the volume depletion and loss of electrolytes (Na⁺, K⁺, H⁺, Cl⁻) stimulate a paradoxical response by the kidneys. The kidneys increase sodium and bicarbonate reabsorption with excretion of hydrogen. Bicarbonate is reabsorbed to maintain an anionic balance because the ECF chloride concentration is decreased.
