A nurse is caring for four clients on the urology unit. Which of the following clients should the nurse plan to teach about kidney stone prevention?

A. These findings suggest a chronic kidney condition such as polycystic kidney disease, not acute kidney stones. B. This presentation is consistent with glomerulonephritis, which is not directly related to kidney stones. C. These symptoms are typical of a lower urinary tract issue such as benign prostatic hyperplasia (BPH) or urinary tract infection (UTI). D.
