A client with end-stage renal disease (ESRD) is receiving erythropoietin-stimulating agents (ESAs) as part of the dialysis treatment. Which of the following statements by the client indicates an understanding of the medication's purpose?

A. Incorrect. Protein intake is essential for maintaining body functions, but clients on dialysis may need to adjust their protein intake based on their individual needs and dialysis prescription.

B. Incorrect. Clients on dialysis may need to limit their sodium intake to manage fluid retention and blood pressure.

C. Correct. Clients on dialysis often need to avoid potassium-rich foods to prevent hyperkalemia, as the kidneys are unable to adequately remove excess potassium from the blood.

D. Incorrect. Clients on dialysis typically need to restrict their phosphorus intake to prevent complications related to high phosphorus levels, such as bone disease and cardiovascular issues.

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.
