A nurse is caring for a client in the emergency department with a diagnosis of renal calculi. Which of the following areas of the renal system do most renal calculi begin forming?
Bladder
Renal papilla
Ureter
Urethra
The Correct Answer is B
Choice A reason: The bladder is not where renal calculi typically begin to form; it is where they may end up if they travel down from the kidneys.
Choice B reason: Renal calculi commonly begin forming at the renal papilla, which is part of the kidney where urine collects before it flows into the ureter.
Choice C reason: The ureter is not the typical starting point for the formation of renal calculi, though stones can travel through it.
Choice D reason: The urethra is not a common site for the formation of renal calculi; it is the duct through which urine is discharged.
