A nurse is assessing a client who has a medical history of chronic kidney disease for fluid volume excess. Which assessment data provides the most reliable measure of fluid retention?

A. Intake and output: Although helpful, intake and output measurements can sometimes be inaccurate, as not all fluid retention may be recorded.B. Daily weight: Daily weight measurements are the most reliable way to assess fluid retention because changes in body weight accurately reflect gains or losses in body fluid, especially in clients with chronic kidney disease.C. Sodium level: Sodium levels can indicate fluid imbalances, but they do not directly measure fluid volume excess.D. Skin tenting: Skin tenting is used to assess dehydration, not fluid retention, and is not a reliable measure in chronic kidney disease.
