Which electrolyte has a direct effect on a client's blood pressure?

Explanation:
Sodium directly affects blood pressure by controlling extracellular fluid volume. It draws water with it, so when sodium intake is high, the body retains more fluid, increasing circulating blood volume. That extra volume raises the pressure in the arteries. Conversely, lowering sodium reduces fluid volume and lowers blood pressure. Hormones like aldosterone link sodium balance to BP regulation through the kidneys. The other electrolytes can influence blood pressure, but their effects are more about vascular tone and regulatory mechanisms rather than the direct impact on fluid volume that sodium provides.
