The nurse is administering Furosemide 40 mg PO to a client with peripheral edema. Which method should the nurse use to best evaluate the client's response to this medication?

A. Monitor serum sodium levels: While serum sodium levels can provide some information about fluid balance, they are not the most direct indicator of the effectiveness of furosemide in reducing peripheral edema. B. Auscultate breath sounds: This is important for monitoring potential fluid overload or pulmonary complications, but it does not directly assess the reduction of peripheral edema, which is the primary concern with furosemide administration. C. Perform daily weights: This method is the best way to evaluate the client's response to furosemide. Daily weights can provide a clear indication of fluid status and changes in peripheral edema, as a decrease in weight typically reflects effective diuresis. D. Take the blood pressure: While monitoring blood pressure is important, especially in clients receiving diuretics, it does not specifically measure the effectiveness of the medication in addressing peripheral edema.
