A client with ESRD is receiving hemodialysis. The client asks the nurse about the purpose of this treatment. Which response by the nurse is accurate?

A. This statement is incorrect. Limiting potassium intake is not primarily related to preventing dehydration and electrolyte imbalances.

B. This statement is incorrect. While reducing potassium intake can be beneficial for kidney function, it is not the primary reason for limiting potassium in clients with ESRD.

C. This statement is incorrect. Although adequate calcium intake is essential for bone health, it is not the main reason for limiting potassium in ESRD clients.

D. This statement is correct. Clients with ESRD have impaired kidney function, which can lead to decreased potassium excretion. Excess potassium in the bloodstream can result in dangerous heart rhythm disturbances (arrhythmias) and muscle weakness. Limiting dietary potassium helps prevent these complications and maintain a safe level of potassium in the body.

A. This is correct. Hemodialysis is performed to remove waste products and excess fluids from the body, but there is a risk of fluid overload during the procedure. It is essential for the client to be monitored for signs of fluid retention, such as swelling and shortness of breath.

B. This is incorrect. Hemodialysis typically reduces fluid overload and may lead to decreased appetite and weight loss, not weight gain.

C. This is incorrect. Hemodialysis is used to manage fluid and electrolyte imbalances, including blood pressure regulation. While blood pressure may fluctuate during the dialysis procedure, it is not a common complication to increase blood pressure.

D. This is incorrect. Hemodialysis is used to regulate potassium levels in clients with ESRD, as high potassium levels can be dangerous. It is more common for potassium levels to be reduced during hemodialysis, not increased.
