A patient with unregulated Type 1 diabetes presents with fruity-smelling breath and rapid, deep breathing. This respiratory pattern is a homeostatic response to metabolic acidosis.
According to Le Châtelier's principle, how does hyperventilation help restore blood pH?
- By exhaling CO_2, the equilibrium shifts to consume H^+ ions.
- By inhaling more O_2, the kidneys are stimulated to excrete more bicarbonate.
- By increasing blood CO_2 levels, the buffer system is replenished.
- By converting ketone bodies directly into O_2 in the lungs.
