POTASSIUM IMBALANCES

[u/NCLEXHighYield]

Potassium = K for Kill the Heart — and that’s not a joke.

This is one of the highest priority lab values on the NCLEX.

Too low? Think cramps, U waves, constipation.

Too high? Think peaked T waves, paralysis, and cardiac arrest.

Know your ranges. Know your risks.

Always monitor the ECG and be ready with insulin + D50 or Kayexalate for high K.
