Isotonic saline infusion Incorrect Isotonic saline infusion is only used with symptomatic cases of hyponatremia, when the sodium level reaches 125 mmol/L. Hypertonic saline infusion Incorrect Hypertonic saline infusion is only used with sever symptomatic cases of hyponatremia to prevent cerebral edema. Water restriction Correct In asymptomatic euvolemic hyponatremia, fluid restriction (less than 1 to 1.5 L per day) is the mainstay of the treatment. Intravenous diuretics Incorrect Intravenous diuretics is not indicated in the management of hyponatremia. The decrease in effective circulating arterial volume due to this patient`s liver disease is responsible for ADH secretion in this patient. Hyponatremia is defined as plasma sodium concentration less than 135 mEq/L. Most patients with hyponatremia are asymptomatic. Symptoms do not usually appear until the plasma sodium level drops below 120 mEq per L. Hyponatremia can be developed in cases of excess water intake that exceed the excretory capacity of the kidneys. Other causes include impaired renal functions and ability to excrete excess water, or inappropriate secretion of ADH.
