POTASSIUM-HYPOKALEMIA MANIFESTATIONS & MANAGEMENT

1. Severe hypokalemia may cause U waves, decreased deep tendon reflexes, and rhabdomyolysis.

2. Treat contributing factors such as volume depletion and/or metabolic alkalosis.

3. Replace potassium orally when possible.

4. Poor response generally implies a large deficit and merely requires more K + .

5. Comorbid magnesium deficiency causes renal potassium wasting, so always check and replenish Mg stores.
