Potassium disturbances can make or break your shelf exam performance—and your patient’s outcome. Whether it’s a sneaky NG tube–induced hypokalemia or a burn patient at risk for fatal hyperkalemia, knowing the patterns, EKG changes, and pitfalls is non-negotiable.

In this high-yield episode, Chris and Mars break down hypokalemia and hyperkalemia from the ground up, covering GI losses, Conn syndrome, hypomagnesemia, renal failure, trauma, adrenal insufficiency, pseudohyperkalemia, and tumor lysis syndrome. You’ll learn when to act fast, how to avoid common traps, and why magnesium is the unsung hero of potassium management.

We cover: • How chloride-responsive alkalosis clues you in to GI loss–related hypokalemia • The EKG giveaways for both high and low potassium states • Why correcting magnesium is step zero in refractory hypokalemia • First-line cardiac stabilization in hyperkalemia with EKG changes • The 24-hour succinylcholine rule in burn and trauma patients

Perfect for med students prepping for the surgery shelf, wards, or boards—this one’s packed with exam-ready pearls and life-saving takeaways.
