Sodium chloride

Rationale: A potassium level of 4.5 mEq/L is within normal range. A sodium level of 132 mEq/L is low, indicating hyponatremia. In clients with hyponatremia, sodium chloride (isotonic) should be used rather than water for gastrointestinal irrigations. Test-Taking Strategy: Use the process of elimination. Eliminate options A, B, and D because they are comparative or alike (sterile water, tap water, and distilled water). Also, recalling that the serum sodium level identified in the question indicates hyponatremia will direct you to option C. If you had difficulty with this question, review the care of the client experiencing hyponatremia.
