Electrolyte Imbalances · NCLEX Exam

A nurse observes a patient with serum sodium of 160 mEq/L being restless, flushed and dehydrated. What is the most appropriate nursing intervention?

  1. Rapidly infuse hypotonic fluid to drop sodium quickly
  2. Administer hypertonic saline to raise serum sodium
  3. Slowly infuse isotonic/hypotonic fluid with monitoring
  4. Administer a loop diuretic immediately to excrete sodium
Show answer and explanation

Correct answer: Slowly infuse isotonic/hypotonic fluid with monitoring

In hypernatremia, the correct approach is to lower sodium slowly to avoid cerebral edema; rapid correction or wrong fluid can cause harm.
