A client with fluid volume overload is admitted to the hospital for diuresis. Which assessment should the nurse perform to evaluate the client's fluid balance?

A. Turgor is not a reliable indicator of fluid balance in clients with fluid volume overload, as it is more commonly used to assess dehydration. B. Blood pressure is affected by fluid volume but is not a direct or specific measure of fluid balance. Other factors, such as medication or underlying conditions, can influence blood pressure. C. Weight is the most accurate and sensitive indicator of fluid balance. A change in weight directly correlates with fluid retention or loss, making it the preferred method for evaluating fluid balance. D. Lung sounds can indicate fluid overload if crackles are present, but they are not a quantitative measure of fluid balance and do not provide ongoing assessment of fluid changes.
