الإجابة: B. Metabolic acidosis partly compensated by respiratory alkalosis
pH 7.2 with HCO3 10 is a metabolic acidosis (DKA). Winter's formula gives an expected PCO2 of 1.5 x 10 + 8 = 23 +/- 2 (21-25); the measured PCO2 of 25 shows respiratory compensation is present. The pH is still abnormal, so it is partially compensated. 'Not compensated' (A) is wrong because PCO2 has fallen appropriately.

A
ليش غلط
Uncompensated means no attempt at compensation. Here PCO2 is 25 (normal 35-45), so the lungs are already compensating; the abnormal pH shows it is only partial.

B
ليش صح
pH 7.2 with HCO3 10 is a metabolic acidosis. The low PCO2 (25) is the lungs' compensation, and because the pH is still abnormal the compensation is partial.

C
ليش غلط
Alkalosis means a high pH (>7.45). This patient's pH is 7.2 and HCO3 is low, so this is an acidosis, not a metabolic alkalosis.
