What type of IV fluid would be used to treat severe hyponatremia?

• A. Hypotonic solution
• B. Isotonic solution
• C. Colloid solution
• D. Hypertonic solution

Answer: (D)

In the treatment of severe hyponatremia, hypertonic solutions are specifically used to raise serum sodium levels effectively and safely. Hypertonic saline, usually in concentrations such as 3% sodium chloride, is administered to provide a higher concentration of sodium ions compared to the fluid in the patient's bloodstream. This facilitates the movement of water out of cells, helping to correct the imbalance of sodium levels in the body. The use of hypertonic solutions is critical because hyponatremia can lead to serious neurological complications due to swelling of brain cells, and rapid correction of sodium can prevent further complications. In clinical practice, hypertonic saline is administered under careful monitoring to avoid overly rapid changes in serum sodium levels, which can lead to other complications such as osmotic demyelination syndrome. In contrast, hypotonic solutions would further dilute serum sodium levels and worsen hyponatremia, isotonic solutions would not correct the sodium deficit effectively, and colloid solutions are not specifically aimed at correcting sodium levels but are instead used to expand blood volume by increasing oncotic pressure. Hence, the application of a hypertonic solution is critical in the management of severe hyponatremia.
