Hyponatremia can sometimes be seen in individuals whose ECF volume is decreased by more than 10%.Which of the following factors contributes to the development of hyponatremia in this situation? A)Decreased levels of ADH B)Elevated levels of natriuretic peptides C)Increased excretion of Na⁺ by the kidneys D)Reduced excretion of solute-free water by the kidneys E)Development of positive Na⁺ balance

Question

When there is a decrease in ECF volume, the kidneys may try to conserve water by reducing excretion of solute-free water, leading to an increase in water retention and subsequent dilution of sodium. This can result in hyponatremia. Therefore, reduced excretion of solute-free water by the kidneys is the factor that contributes to the development of hyponatremia in this situation.
