Which electrolyte abnormality is a well-known systemic side effect of high-dose Beta-2 agonist therapy?

Correct answer: Hypokalemia
Beta-2 stimulation activates the Na+/K+-ATPase pump, which drives potassium from the extracellular fluid into the intracellular compartment. This can lead to transient hypokalemia, especially during nebulized emergency treatments.
