I think it is D increased secretion of H+

That was my answer too, but its not correct. Which is why I posted it here. Try again!

Hyperkalemia is mostly causing Acidosis or eventually does occur in Acidosis so Since Kidney r counteract by producing Alkalosis

Aren't the pairs A/D and B/C mutually exclusive, respectively? I mean, D would result in A and C in B, making those options unlikely, and the remaining best option would be E

The thread where I got this q from said the answer was B (Acidosis)
Explanation given:
1) more K+is being excreted while H+ is being conserved in the DCT
2)Involves the aldosterone-mediated K+/H+ pump, so the body would not pull back K+ and would therefore hold onto H+...it would not be able to regenerate HCO3- and would develop acidosis.
I think the key thing is that the question is asking about RENAL correction and not the response by cells in the body.

I got it from this website at a later page. Here's the link -

Idiopathic (and I've followed a lot of his posts and he's usually on money) thinks its B also.

renal correction of hyperkalemia - sort of same like you give thiazide, which toxicity is hypokalemic metabolic alkalosis

im also going for Acidosis... no doubt , reason... explained very well above !

actually , me007 is a different story with THIAZIDEs
Thiazides diuretic administr---> increases flow thru distal tubule----> dilute luminal K ion concentr.----> increasing FORCE driving K ion secretion---> hence Metab. Alkalosis
It is a FORCE driving K ion secr tru luminal mb. !!!
In the case of Hyper K -emia---> more K is been filtered upstream(constant filtered load from more means more right?)---> therefore INCRESE K delivery downstream----> wich decr. this Force of K secretion at the level of Collecting tubule----> K is kept inside cell anfd H ion is also hold inside cell----> Acidosis by not reabsorbing HCO3 in the blood

Lucky, it is just logic
hyperkalemia associated with acidosis
acidosis - more H+ around --> more H+ enters cells, K+ exit cells.
so, correction will be associated with alkalosis

007, you bring a compelling explanation to the problem at hand. But what's your take on:
Inc K+ --> K+ in cells (distal tubule), H+ rushes out to blood. Now because of inc K+ conc in distal cells, it can go into the tubular lumen by passive diffusion (BRS) --> acidosis
