Which consequence results when excessive hydration during intense electrolyte loss?

A)Decrease in extracellular sodium ions
B)Rise of intracellular potassium ions
C)Increased neuromuscular action potential duration
D)Elevated osmotic pressure in brain cells

💡 Explanation

Hyponatremia occurs because the **ionic** concentration of sodium is reduced in extracellular fluid during dilution. This is **osmotic dilution**, therefore sodium concentration drops rather than remaining stable or increasing. Potassium or action potentials or pressures do not directly respond to water loading this way.
