its DD type 4 RTA only hav hyperkalemia..........

[ArchivalUser]

yes ans is D) RTA type 4.

In type 4 RTA associated with diabetes and
hypertension, damage to the juxtaglomerular
apparatus in the glomeruli leads to decreased
renin production. This results in a state of
hypoaldosteronism, causing hyperkalemia and
a nongap metabolic acidosis.
