Question 7

A patient is diagnosed with severe metabolic acidosis. Which of the following physiological compensatory mechanisms would be the MOST immediate and significant in attempting to restore the blood pH towards its normal range?

Accepted Answer

B. Hyperventilation to reduce arterial PCO2. — Hyperventilation is the most immediate and significant compensatory mechanism for metabolic acidosis. By increasing the rate and depth of breathing, the body rapidly expels more carbon dioxide, thereby reducing arterial PCO2 and shifting the bicarbonate buffer system equilibrium to decrease hydrogen ion concentration and raise pH. Increased renal reabsorption of bicarbonate ions and enhanced secretion of aldosterone are renal compensatory mechanisms, which are slower to act compared to respiratory compensation. Activation of the thirst mechanism is related to fluid balance and osmoregulation,
