Acute compensation for metabolic acidosis includes: A) kidney excretion of H⁺. B) hyperventilation. C) CO₂ retention. D) aldosterone secretion.

Question

Quizplus · Accepted Answer

During metabolic acidosis, the body compensates by increasing ventilation in order to decrease carbon dioxide levels and increase pH. This is known as respiratory compensation. Kidney excretion of hydrogen ions (H+) and retention of bicarbonate ions (HCO3-) is a form of chronic compensation. Retention of vitamin B12 or aldosterone secretion is not known to be a compensatory mechanism for metabolic acidosis.
