Final answer:
To determine the cause of ascites in chronic liver disease, albumin levels should be evaluated since they are critical in maintaining the osmotic pressure necessary to prevent fluid accumulation in the abdominal cavity. The correct option is B.
Step-by-step explanation:
When trying to determine the cause of ascites related to chronic liver disease, the nurse should evaluate albumin levels. Ascites, which is fluid retention in the abdominal cavity, is a common complication of cirrhosis and is linked to a decrease in albumin concentration.
Albumin, a protein produced by the liver, helps to maintain osmotic pressure in the blood vessels. Reduced levels of albumin can lead to fluid leaking into the abdominal cavity, resulting in ascites. Therefore, assessing albumin levels is essential in patients with severe ascites to understand the extent of liver dysfunction.
