Reads what your course gives you. Writes for the exam you’re sitting.
01Cited
Notes, answers and questions point back to the slide, page or timestamp they came from. If there’s no source, there’s no claim.
Note · Loop diuretics
Furosemide inhibits the Na⁺–K⁺–2Cl⁻ cotransporter in the thick ascending limb. That removes the lumen-positive potential, so Mg²⁺ and Ca²⁺ are lost in the urine. Ototoxicity is dose-related and worse alongside aminoglycosides.

02Axon, your tutor
Axon answers from your lectures and cites the slide. Analogy first, then the mechanism, then the pearl the exam is fishing for. Anything it adds is labelled Beyond your material.
Why does spironolactone cause hyperkalemia?
Axonanswering from Renal L14 · 3 slides
1Analogy
Think of aldosterone as the shift manager in the collecting duct: it calls in more sodium channels and more pumps. Spironolactone sends the manager home, so the late shift never starts.
2Mechanism
Renal L14 · Slide 23
3Beyond
Beyond your materialEplerenone is more selective for the mineralocorticoid receptor, so it causes less gynecomastia. Your lecture doesn’t cover it; your exam might.
4Exam pearl
PearlK⁺-sparing diuretic plus an ACE inhibitor or ARB: check the potassium before you pick the answer about arrhythmia.

Every question is re-answered blind by a second AI before you see it. If it doesn’t land on the key, and the key isn’t in your source, the question is thrown away.

07FAQ
Everything nuchub writes cites the slide, page or timestamp it came from. Every question is re-answered blind by a second AI before you see it, and questions where the two disagree are thrown away. When something was read by OCR or from auto-captions we say so, because drug names and doses deserve a second look.
