A client is prescribed alpha-blockers as part of the management of renal calculi. The nurse explains that these medications can help with stone passage by:

A. This statement is not correct. If a client has calcium oxalate stones, they should limit foods high in oxalate, such as spinach and nuts, to reduce the risk of stone formation.

B. This is the correct answer. Calcium oxalate stones are the most common type of kidney stone. Reducing dietary calcium intake can help prevent the formation of calcium oxalate stones. However, it is important to note that not all clients with kidney stones should reduce their calcium intake, as calcium is essential for bone health and other bodily functions.

C. Avoiding foods high in purines is more relevant to the prevention of uric acid stones, not calcium oxalate stones.

D. While reducing sodium and processed foods can be beneficial for overall health, it is not a specific dietary modification for preventing calcium oxalate stones.

A. This is the correct answer. After a ureteroscopy, the client may experience postoperative urinary retention due to swelling or irritation in the urethra or bladder. The nurse should monitor for signs of urinary retention and take appropriate measures to address it.

B. Hyperkalemia is not directly related to ureteroscopy. It may occur in certain medical conditions but is not a common complication of this procedure.

C. Hypertension is not directly related to ureteroscopy. While some clients with hypertension may be at increased risk for kidney stones, hypertension is not a common complication of the procedure itself.

D. Hypoglycemia is not related to ureteroscopy. It is a condition related to low blood sugar levels and is not a typical complication of kidney stone removal.
