← Human Body & HealthWhich physiological outcome develops when excessive fluid intake overwhelms renal handling capacity?
A)Dilutional hyponatremia reduces neural excitability✓
B)Hypertonic dehydration impairs cellular functions
C)Metabolic acidosis increases bone reabsorption
D)Respiratory alkalosis induces cerebral vasodilation
💡 Explanation
Dilutional hyponatremia arises because water retention overwhelms sodium balance limits through renal reabsorption capacity; therefore, electrolyte concentrations drop, reducing neural excitability via osmotic imbalances; rather than hypertonic dehydration induced by water loss.
