A 52-year-old man was referred to the clinic due to increased abdominal girth. He is diagnosed with ascites by the presence of a fluid thrill and shifting dullness on percussion. After administering diuretic therapy, which nursing action would be most effective in ensuring safe care?
For the client with ascites receiving diuretic therapy, careful intake and output measurement are essential for safe diuretic therapy. 
Diuretics lead to fluid losses, which if not monitored closely and documented, could place the client at risk for serious fluid and electrolyte imbalances. 
Hypokalemia, not hyperkalemia, commonly occurs with diuretic therapy. Because urine output increases, a client should be assessed for hypovolemia, not hypervolemia.
Weights are also an accurate indicator of fluid balance. However, for this client, weights should be obtained daily, not weekly.
Measuring serum potassium for hyperkalemia
Assessing the client for hypervolemia
Measuring the client’s weight weekly
Documenting precise intake and output
