What happens when a disorder disrupts electrolyte balance in the blood?

• A. It instantly stabilizes the membrane potential.
• B. It eventually affects the balance of cations and anions in tissue cells.
• C. It has no effect on tissue cells.
• D. It only affects the plasma proteins.

Answer: (B)

Electrolytes create transmembrane ion gradients that establish and maintain membrane potential and cellular function. When a disorder disrupts electrolyte balance in the blood, those gradients are perturbed, and cells must respond to altered ion availability. Over time, this disruption changes the balance of cations and anions inside tissue cells, which can affect excitability, signaling, and metabolic processes. That is why the option describing an eventual impact on the balance of cations and anions in tissue cells is the best description of the consequence. An immediate stabilization of membrane potential wouldn’t follow from a disturbance; disturbances typically destabilize potentials. Claiming no effect on tissue cells contradicts the role of ion gradients in cellular function. Saying only plasma proteins are affected ignores the central role of electrolyte ions in cells and tissues.
