A nurse is caring for a client with acute renal failure who is prescribed hemodialysis. The client asks, "What is the purpose of hemodialysis?" What is the nurse's best response?

A. Incorrect. Hemodialysis is not a procedure for kidney transplantation.

B. Correct. Hemodialysis is a treatment that helps remove waste products, toxins, and excess fluids from the blood when the kidneys are not functioning properly. It helps maintain the body's internal environment and prevent complications of acute renal failure.

C. Incorrect. While hemodialysis can improve kidney function temporarily, its primary purpose is to provide kidney support and replace some of the kidney's functions.

D. Incorrect. The description provided refers to the insertion of a urinary catheter for bladder drainage, not hemodialysis.

A. Incorrect. Loop diuretics are used to increase urine output, not decrease it. They help reduce fluid overload and prevent dehydration.

B. Incorrect. Loop diuretics typically lead to a decrease in blood pressure, not an increase. They are often prescribed to address hypertension in acute renal failure.

C. Incorrect. Loop diuretics promote the excretion of sodium and water from the kidneys, not their reabsorption.

D. Correct. Loop diuretics are prescribed in acute renal failure to increase urine output and promote fluid excretion. This helps reduce fluid overload and decrease edema.
