What symptom is NOT typically associated with hyponatremia until Na< 120?

Headache
Nausea
Seizures
Respiratory arrest

The correct answer is: Nausea

Hyponatremia is a condition where the body has abnormally low levels of sodium in the blood. Sodium is important for maintaining the balance of fluids in the body and for nerve and muscle function. When the sodium levels drop below 120, it is considered a severe case of hyponatremia. The most common symptoms associated with this condition include headache, seizures, and respiratory arrest. These symptoms are caused by the imbalance of fluids and the effect on the nervous system. Nausea, on the other hand, is not typically associated with hyponatremia until the sodium levels drop below 120. While it can occur in severe cases, it is not a common symptom and is not typically associated with hyponatremia. Therefore, it is the correct answer for this question.
