A nurse is caring for a client who is receiving 0.45% sodium chloride. Which of the following actions should the nurse take?

Choice A reason: Hypernatremia is unlikely with 0.45% sodium chloride, a hypotonic solution that dilutes serum sodium. Over-infusion risks hyponatremia, not high sodium levels. Monitoring for hypernatremia is inappropriate, as the solution’s low sodium content does not contribute to elevated sodium in fluid therapy. Choice B reason: Assessing for fluid overload is essential, as 0.45% sodium chloride, being hypotonic, can cause water to shift into cells, risking pulmonary or cerebral edema. This is critical in clients with renal or cardiac issues, where monitoring for dyspnea or swelling ensures safe fluid administration. Choice C reason: Hypoglycemia is not directly linked to 0.45% sodium chloride, which affects fluid and electrolytes, not glucose. Fluid shifts may indirectly stress metabolism, but hypoglycemia relates to fasting or insulin issues, making this an inappropriate focus for monitoring in this fluid therapy context. Choice D reason: Dehydration is unlikely, as 0.45% sodium chloride provides free water, promoting hydration. It corrects hypernatremia or replaces fluid losses. Evaluating for dehydration is unnecessary unless infusion is inadequate or losses persist, which is not indicated in the context of this hypotonic solution.
