A client with acute renal failure is prescribed loop diuretics to manage fluid overload. What is the nurse's responsibility when administering loop diuretics?

Monitor the client's serum potassium levels frequently.

Administer the diuretics intravenously to ensure rapid action.

Encourage the client to restrict fluid intake while on diuretic therapy.

Instruct the client to take the diuretics at bedtime for better effectiveness.

Answer and Explanation

The Correct Answer is A

A. Correct. Loop diuretics can cause potassium loss and potentially lead to hypokalemia. The nurse should monitor the client's serum potassium levels frequently to assess for any imbalances.

B. Incorrect. While loop diuretics can be given intravenously for rapid action, the administration route depends on the client's condition and the healthcare provider's order.

C. Incorrect. Loop diuretics are used to promote diuresis and fluid removal from the body. Encouraging fluid restriction while on diuretic therapy may exacerbate dehydration and electrolyte imbalances.

D. Incorrect. The timing of loop diuretic administration is determined by the healthcare provider's order and the client's specific needs. Taking diuretics at bedtime may result in increased nighttime urination and sleep disruption.

B. Incorrect. Increased vascular permeability and leakage of fluid into tissues are not the primary mechanisms of edema in acute renal failure.

C. Correct. In acute renal failure, the impaired filtration and reduced excretion of fluid by the kidneys lead to fluid retention and edema in various parts of the body.

D. Incorrect. Excessive fluid intake and fluid overload may contribute to fluid retention and edema in prerenal acute renal failure, but they are not the primary pathophysiological process in acute renal failure.
