A client with acute renal failure due to severe dehydration is receiving treatment to restore kidney function. Which category of acute renal failure is most likely involved in this case?

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.

A) Incorrect. Bradypnea (slow respiratory rate) is not typically associated with acute renal failure.

B) Correct. Kussmaul respirations are rapid and deep respirations seen in metabolic acidosis, a common complication of acute renal failure. The body tries to compensate for the acidosis by increasing the elimination of carbon dioxide through rapid and deep breathing.

C) Incorrect. Dyspnea and crackles in the lungs are not directly related to acute renal failure.

D) Incorrect. Increased respiratory rate and shallow breathing are not typical respiratory manifestations of acute renal failure.
