In this high-yield episode of One Stem at a Time, we break down hyperkalemia the way board exams (and real patients) demand you understand it.

We walk step-by-step through the physiology of potassium, the classic EKG progression from peaked T waves to sine wave arrest, and the exact treatment algorithm you need to know for exams and the wards. Then we tackle one of the most commonly tested (and most dangerous) clinical pitfalls: potassium management in diabetic ketoacidosis (DKA).

By the end of this episode, you’ll be able to recognize hyperkalemia instantly, treat it in the correct order under pressure, and avoid the classic DKA potassium mistake that trips up students and residents alike.

Perfect for: medical students, COMLEX/USMLE prep, and early residents. Topics covered include hyperkalemia physiology, EKG changes, emergent treatment, insulin effects on potassium, and DKA potassium correction
