A client with acute renal failure is receiving continuous renal replacement therapy (CRRT). What is the primary advantage of CRRT compared to intermittent hemodialysis?

CRRT allows for more rapid removal of waste products and excess fluids.

CRRT requires less frequent sessions, providing greater convenience for the client.

CRRT does not require the use of anticoagulants to prevent blood clotting in the machine.

CRRT is less expensive and more cost-effective than intermittent hemodialysis.

Answer and Explanation

The Correct Answer is C

A. Incorrect. Continuous renal replacement therapy (CRRT) provides gradual and continuous removal of waste products and excess fluids from the blood, but it may not be as rapid as intermittent hemodialysis.

B. Incorrect. CRRT typically requires continuous sessions, which may last 24 hours or more. Intermittent hemodialysis involves shorter but more frequent sessions.

C. Correct. One of the primary advantages of CRRT is that it does not require the use of anticoagulants to prevent blood clotting in the machine. This reduces the risk of bleeding and other complications associated with anticoagulant use during hemodialysis.

D. Incorrect. The cost of CRRT and intermittent hemodialysis can vary based on the healthcare setting and the client's needs. The cost-effectiveness depends on individual factors and resource availability.

Correct Answer is B

Explanation

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. Increase the rate of dialysis to complete the procedure quickly. B. Administer an antihypertensive medication to lower the blood pressure. C. Stop the dialysis procedure and notify the healthcare provider. D. Increase the client's fluid intake to raise blood pressure.

Correct Answer is C

Explanation

A. Incorrect. Increasing the rate of dialysis may further lower the client's blood pressure and worsen the situation.

B. Incorrect. Administering an antihypertensive medication during a hypotensive episode could exacerbate the client's low blood pressure.

C. Correct. The nurse's priority action is to stop the dialysis procedure immediately and notify the healthcare provider of the significant drop in blood pressure. The client may be experiencing a hypotensive episode, which requires prompt evaluation and intervention.

D. Incorrect. Increasing the client's

fluid intake is not appropriate during a hypotensive episode, as it may not rapidly improve blood pressure and could lead to fluid overload.
