Hyperkalemia commonly presents with what type of medical problem?

• A. Kidney stones
• B. Migraines
• C. Skin ulcers
• D. Cardiac problems

Answer: (D)

Elevated potassium directly disrupts the heart’s electrical system, so cardiac problems are the hallmark of hyperkalemia. When potassium outside the cells rises, the resting membrane potential becomes less negative, which initially can increase excitability but quickly leads to inactivation of sodium channels and slowed conduction. This progression produces characteristic ECG changes and can progress to dangerous arrhythmias or cardiac arrest if not treated. The other options aren’t typical manifestations of high potassium—kidney stones, migraines, and skin ulcers aren’t directly caused by hyperkalemia.
