A. HCO3 12, pH 7.19, PaCO2 29
B. HCO3 23, pH 7.36, PaCO2 36
C. HCO3 10, pH 7.65, PaCO2 47
D. PaCO2 49, pH 7.55, HCO3 21

Normal ABG values are pH 7.35–7.45, PaCO2 35–45, HCO3 22–26. Option A indicates acidosis (pH < 7.35) due to low HCO3, consistent with Diamox’s effect, and the low PaCO2 shows compensation. Option B is normal, C shows alkalosis, and D is incomplete and inconsistent with symptoms. The patient’s confusion, fatigue, and headaches align with metabolic acidosis.
