← Human Body & HealthWhich consequence results when excessive insulin therapy drives electrolyte imbalance?
A)Hypokalemia and potential cardiac arrhythmia✓
B)Reduced renal sodium reabsorption rate
C)Increased parathyroid hormone secretion
D)Hypercalcemia and muscle over-excitability
💡 Explanation
Insulin stimulates Na+/K+-ATPase activity, driving potassium into cells, causing hypokalemia; therefore, cardiac arrhythmia risk increases rather than electrolyte balance improvement, because normal potassium levels maintain cardiac action potentials.
