Flashcard 83: In a low K+ state, _____ is exchanged for Na+ in the cortical collecting tubule, causing alkalosis and "paradoxical aciduria"
Answer: H+
Extra: Paradoxical aciduria occurs in states of hypokalemia and volume depletion (e.g., due to loop or thiazide diuretics).
When K+ is low, the kidneys attempt to reabsorb Na+ (driven by aldosterone) in the cortical collecting tubule. Since K+ is unavailable to be secreted in exchange for the reabsorbed Na+, H+ is secreted into the lumen instead. This results in acidic urine despite the presence of systemic metabolic alkalosis.
Flashcard 84: _____ is also known as volatile acid
Answer: CO2
