A nurse is caring for a client who is receiving hemodialysis. Which of the following client measurements should the nurse compare before and after dialysis treatment to determine fluid losses?

A. Comparing a client’s body weight before and after hemodialysis is the most reliable method to determine fluid removal during treatment. The difference in weight reflects the amount of fluid removed, as hemodialysis removes excess fluid along with waste products. This measurement is considered the gold standard for assessing fluid balance in dialysis patients. B. Blood pressure can fluctuate during dialysis due to fluid shifts and changes in vascular resistance. While it provides information about hemodynamic stability, it is not a direct measurement of fluid loss. C. Distended neck veins indicate fluid overload or right-sided heart failure, but this assessment is subjective and less precise for quantifying fluid loss during dialysis. D. Changes in abdominal girth can reflect ascites or severe fluid accumulation, but this measurement is not sensitive enough to assess routine fluid removal during dialysis.
