A patient has mild hyponatremia (Na⁺ = 132 mEq/L), asymptomatic. What is the recommended management?

Correct option is A

Mild hyponatremia (130–135 mEq/L) without symptoms is best managed with fluid restriction and observation. IV fluids are not needed unless symptomatic or volume-depleted.
Explanation of options: (a) ✔ Correct; fluid restriction is standard for mild cases. (b) ✘ 3% NS reserved for severe symptomatic hyponatremia (<120). (c) ✘ 0.9% NS is given if hypovolemic, not in euvolemic mild cases. (d) ✘ Dialysis only in refractory severe hyponatremia.
