When you think hyperkalemia, think what?

• A. Respiratory distress
• B. Cardiac problems
• C. Abdominal pain
• D. Skin rashes

Answer: (B)

High potassium levels mainly threaten the heart. Potassium sets the electrical readiness of cardiac cells. When potassium in the blood rises, the resting membrane potential becomes less negative, which alters how cardiac cells conduct electricity. That leads to characteristic ECG changes and can progress to dangerous rhythms. So when you think hyperkalemia, think about cardiac problems first because the heart is the most life‑threatening system affected. Early signs include changes on the ECG such as tall peaked T waves and widening of the QRS, and these can progress to potentially fatal arrhythmias if not treated promptly. Other symptoms like respiratory distress or skin rashes are not the primary association, even though extreme hyperkalemia can affect muscles and other systems.
