In clients with ascites, which is the accumulation of fluid in the abdominal cavity due to liver disease, administration of serum albumin can help shift the fluid from the abdominal cavity back into the blood vessels. As a result, the expected outcome of this treatment would be a decrease in abdominal girth as the fluid is reabsorbed and redistributed. Administering serum albumin would not directly affect urinary output, serum ammonia levels, or hepatic encephalopathy.
