Question

What laboratory findings indicate hypernatremia?

a) Serum Na+ level > 145mEq/L and serum osmolality > 295 mOsm/kg, urine specific gravity of 1.030
b) Serum Na+ level < 135mEq/L and serum osmolality < 280 mOsm/kg, urine specific gravity of 1.010
c) Serum Na+ level > 150mEq/L and serum osmolality > 300 mOsm/kg, urine specific gravity of 1.025
d) Serum Na+ level < 140mEq/L and serum osmolality < 290 mOsm/kg, urine specific gravity of 1.020

Answer 1

The laboratory findings that indicate hypernatremia are a high serum sodium level, high serum osmolality, and urine specific gravity of 1.030.

Step-by-step explanation:

The laboratory findings that indicate hypernatremia are a) Serum Na+ level > 145mEq/L and serum osmolality > 295 mOsm/kg, urine specific gravity of 1.030.

Hypernatremia is an abnormal increase of blood sodium, which can result from water loss from the blood or hormonal imbalances involving ADH and aldosterone.

Urine specific gravity is a measure of the quantity of solutes per unit volume of urine, and a higher specific gravity can indicate hypernatremia.
