A client with chronic kidney disease (CKD) is at risk of developing ascites due to impaired fluid regulation. The nurse explains that the kidneys' primary function related to fluid balance is:

Choice A reason:

Mild ankle edema is not uncommon in clients with fluid retention, such as ascites. While it requires monitoring, it does not indicate an immediate need for intervention.

Choice B reason:

Moderate abdominal distention is a common finding in clients with ascites and should be monitored, but it does not require immediate intervention.

Choice C reason:

Complaints of thirst and dry mouth may indicate dehydration, which should be addressed, but it does not require immediate intervention as other options.

Choice D reason:

This statement is correct. Respiratory distress and cyanosis are concerning findings in a client with ascites, as they may indicate severe pulmonary edema or other respiratory complications that require immediate intervention and medical attention.

Choice A reason:

Regulation of blood glucose levels is not a primary function of the kidneys in fluid balance. It is primarily related to the endocrine system and insulin regulation.

Choice B reason:

Maintenance of acid-base balance is a critical function of the kidneys but is not directly related to fluid balance leading to ascites.

Choice C reason:

Production of red blood cells occurs in the bone marrow, not the kidneys. While the kidneys produce erythropoietin, a hormone that stimulates red blood cell production, this is not the primary function related to fluid balance.

Choice D reason:

This statement is correct. The kidneys' primary function related to fluid balance is filtration and excretion of waste products and excess fluid, which helps maintain proper fluid balance in the body. In chronic kidney disease (CKD), impaired kidney function can lead to fluid retention and contribute to the development of ascites.
