Sodium modeling in hemodialysis refers specifically to the practice of altering the concentration of sodium in the dialysis solution during the treatment. This process is implemented to better manage fluid and electrolyte balance for the patient.

In hemodialysis, sodium levels in the dialysate can be adjusted at different points in the treatment to help promote desired changes in the patient’s body. For instance, decreasing the sodium concentration can encourage the patient’s body to eliminate excess fluid more effectively, while increasing it may help maintain blood pressure stability.

The practice is important for optimizing treatment outcomes and tailoring sessions to individual patient needs, addressing issues like fluid overload, hypertension, or cramping—all of which may arise from imbalances in sodium levels during dialysis.

The other options do not accurately capture the concept of sodium modeling as it specifically pertains to adjusting dialysate composition in relation to sodium concentration.
