Q1
A patient with chronic obstructive pulmonary disease has baseline arterial blood gases: $P_{a}CO_2$ 55 mmHg (reference ~40) and pH 7.32. Over several days, serum $\mathrm{HCO_3^-}$ increases compared with baseline. No acute infection is present. What change is most consistent with the described homeostatic process?
