A client with chronic kidney disease (CKD) is experiencing severe metabolic acidosis, which is not responding to medical management. Which of the following is the primary indication for initiating dialysis in this client?

A) This statement is incorrect. Increasing the rate of fluid removal during dialysis may worsen the client's symptoms of lightheadedness and dizziness, as it can lead to further drops in blood pressure.

B) This statement is incorrect. Administering an antihypertensive medication is not appropriate in this situation, as the client is experiencing symptoms of low blood pressure, not high blood pressure.

C) This statement is accurate. Feeling lightheaded and dizzy during hemodialysis may be a sign of hypotension (low blood pressure), and the nurse should assess the client's blood pressure and pulse rate to determine if intervention is needed.

D) This statement is incorrect. Elevating the client's legs may promote blood flow, but it does not address the immediate issue of lightheadedness and dizziness. Assessing the client's blood pressure and pulse rate is the priority to determine the appropriate intervention.

A)This statement is incorrect. Hemodialysis does not use the peritoneal membrane as a filter. Hemodialysis involves the use of a machine that filters the blood outside the body, not the peritoneal membrane.

B) This statement is incorrect. Continuous ambulatory peritoneal dialysis (CAPD) uses the peritoneal membrane as a filter during manual exchanges of dialysate fluid, not with a machine like automated peritoneal dialysis (APD).

C) This statement is accurate. Automated peritoneal dialysis (APD) uses a machine to perform exchanges of dialysate solution through the peritoneal membrane.

D) This statement is incorrect. Peritoneal dialysis uses the peritoneal membrane as a filter. It involves the instillation and drainage of dialysate fluid into the abdominal cavity through a catheter.
