A nurse is caring for a client who has hyponatremia and is receiving an infusion of a prescribed hypertonic solution. Which of the following findings should indicate to the nurse that the treatment is effective?
Correct answer
A
Rationale
The correct answer is A: Improved cognition. Hyponatremia is a condition characterized by low sodium levels in the blood, leading to neurological symptoms like confusion and altered mental status. Administering a hypertonic solution helps increase sodium levels, ultimately improving cognition. Choice B is incorrect because cardiac arrhythmias are not directly related to sodium levels. Choice C is incorrect because vomiting is not a specific indicator of sodium levels. Choice D is incorrect as Chvostek's sign is associated with hypocalcemia, not hyponatremia.
