A nurse is providing postoperative care instructions to a client who underwent ureteroscopy for the removal of a kidney stone. Which of the following statements by the client indicates a need for further teaching?

A. Uric acid stones may cause pain, but they do not typically present with costovertebral angle tenderness. Uric acid stones are more likely to be associated with gout and hyperuricemia.

B. Calcium oxalate stones are common and can cause pain, but they do not typically cause costovertebral angle tenderness. They are more likely to cause localized pain in the back or side.

C. This is the correct answer. Struvite stones, also known as infection stones, can cause severe pain that radiates to the back and lower abdomen. They are often associated with urinary tract infections, and the presence of an infection can lead to costovertebral angle tenderness.

D. Cystine stones are rare and are more likely to cause chronic, dull pain rather than sudden and severe pain with tenderness.

A. Fever and chills are more commonly associated with a urinary tract infection, which can sometimes be a complication of kidney stones. However, the severe pain described is more likely related to the presence of the stone itself.

B. This is the correct answer. Blood in the urine, also known as hematuria, is a common symptom of kidney stones. As the stone moves through the urinary tract, it may cause irritation and small blood vessels may be damaged, resulting in blood in the urine.

C. Difficulty starting the urine stream is not a specific symptom of kidney stones. It may be seen in other urinary conditions but is not typically associated with stones.

D. The frequent urge to urinate may be experienced if the stone causes irritation in the bladder, but it is not the most common symptom associated with kidney stones.
