Question

Quizplus · Accepted Answer

Hypernatremia occurs because of (1)inadequate free water intake,(2)inappropriate administration of hypertonic saline solution (e.g.,sodium bicarbonate for treatment of acidosis during cardiac arrest),(3)high sodium levels as a result of oversecretion of aldosterone (as in primary hyperaldosteronism),or (4)Cushing syndrome (caused by the excess secretion of adrenocorticotropic hormone [ACTH],which also causes increased secretion of aldosterone).The other options do not result in hypernatremia.
