Which is NOT an indicator of hypernatreamia?

Question

BlackTom AI · Accepted Answer

When evaluating indicators of hypernatremia, we consider whether the serum sodium level or related clinical signs reflect elevated sodium in the blood.
Option 1: Serum sodium >145 mmol/L. This is a classic laboratory indicator of hypernatremia, since the normal upper limit is around 145 mmol/L, and values above this point signify increased sodium in the extracellular fluid.
Option 2: Serum sodium <135 mmol/L. This falls into the range of hyponatremia (low serum sodium) and does not indicate hypernatremia; in fact, it suggests the opposite electrolyte disturbance. Recognizing this helps avoid misclassifying hyponatremia as hypernatremia.
Option 3: Excessive thirst. Excessive thirst (polydipsia) is a common compensatory response to hypernatremia and dehydration; it signals an elevated osmolar state and supports the possibility of high serum sodium levels.
Option 4: Decreased conscious state. Altered mental status or reduced consciousness can accompany significant hypernatremia due to brain cell dehydration; this is a clinical indicator aligned with hypernatremia, especially in severe cases.
In summary, options describing high serum sodium and related neurological or thirst-related changes align with hypernatremia, while the option describing low serum sodium does not indicate hypernatremia and instead points to hyponatremia.
