A nurse is caring for a client with a history of recurrent kidney stones. Which of the following instructions should the nurse include in the client's discharge teaching to help prevent stone formation?

A. Extracorporeal shock wave lithotripsy (ESWL) does not typically require general anesthesia. It is usually done under sedation or with the use of local anesthesia.

B. The procedure does not involve the insertion of a scope into the urinary tract. ESWL is a non-invasive procedure that uses shock waves to break up the stone from outside the body.

C. This is the correct answer. ESWL involves the use of high-energy shock waves that are focused on the stone to break it up into smaller fragments. The fragments are then passed out of the body through the urine.

D. A urinary catheter is not typically required after ESWL. The client may be encouraged to drink plenty of fluids to help flush out the stone fragments, but a catheter is not usually needed.

Questions

A. Limiting fluid intake to 1 liter per day is not recommended to prevent kidney stone formation. Adequate hydration is essential to

help prevent stone formation, as it helps dilute the urine and reduce the concentration of minerals that can lead to stone formation.

B. Decreasing dietary fiber intake is not a preventive measure for kidney stones. In fact, increasing dietary fiber intake can be beneficial for overall health.

C. Reducing calcium intake from all sources is not recommended to prevent kidney stones. In some cases, reducing dietary calcium intake can actually increase the risk of certain types of kidney stones.

D. This is the correct answer. Increasing citric acid intake can help prevent certain types of kidney stones, such as calcium oxalate stones. Citric acid helps to bind calcium in the urine, reducing the risk of stone formation. Citric acid can be found in citrus fruits and juices, and the nurse may advise the client to include more of these foods in their diet.
