Write answer in between .Q:Following passage of a calcium oxalate stone, a 55-year-old male visits his physician to learn about nephrolithiasis prevention. Which of the following changes affecting urine composition within the bladder are most likely to protect against crystal precipitation?? A: Increased calcium, increased citrate, increased oxalate, increased free water clearance, B: Decreased calcium, increased citrate, increased oxalate, increased free water clearance, C: Decreased calcium, decreased citrate, increased oxalate, increased free water clearance, D: Decreased calcium, increased citrate, decreased oxalate, increased free water clearance, E: Decreased calcium, increased citrate, increased oxalate, decreased free water clearance,  <response>: This is a question about preventing kidney stone formation after passing a calcium oxalate stone. The goal is to alter urine composition in a way that prevents crystal precipitation and stone formation.Choice A would increase calcium, oxalate, and free water clearance, which are all risk factors for stone formation. Choice B would decrease calcium which is good, but increasing oxalate is not good.Choice C would decrease citrate which is bad since citrate complexes with calcium to prevent stone formation. Increasing oxalate is also not good.Choice D is the best option - decreasing calcium and oxalate while increasing citrate and free water clearance would help prevent crystal precipitation and stone recurrence.Choice E would decrease free water clearance which concentrates the urine and increases risk of precipitation.D: Decreased calcium, increased citrate, decreased oxalate, increased free water clearance
