All are true about Renal tubular acidosis except.: (A) Impaired acid production, (B) Impaired bicarbonate resorption, (C) Inability to acidify urine, (D) Nephrolithiasis
Answer is A. *Renal tubular acidosis type 2 is characterized by PCT damage and inability to reabsorb bicarbonate resulting in bicarbonaturia. * The damage to DCT in A 1 leads to an inability to acidify urine due to damage to H+ K+ antipoer * The concomitant calcium loss in urine leads to nephrolithiasis and rickets.
