During the dialysis process, excess fluid in a patient is primarily assessed through?

Weight measurement is the primary method for assessing excess fluid in a patient during the dialysis process. This approach is effective because fluctuations in a patient's weight can directly reflect changes in body fluid volume. During dialysis, patients are typically weighed before and after the treatment to evaluate fluid removal and to monitor for any signs of fluid overload or deficit.

This method provides a clear and quantifiable assessment that can guide treatment decisions, such as adjusting dialysis parameters or addressing issues related to fluid management. While blood tests, blood pressure readings, and urine output can provide important information about a patient’s overall health and kidney function, they do not offer the same direct correlation to excess fluid status as weight measurement does.
