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.

Correct Answer is D
Explanation
Choice A reason: Furosemide does not require a diet low in potassium; in fact, patients may need to increase their potassium intake due to its diuretic effect.
Choice B reason: Patients on furosemide should not limit fluid intake unless specifically instructed by their healthcare provider, as the medication is a diuretic.
Choice C reason: Furosemide is used to treat high blood pressure, so it would not cause an increase in blood pressure.
Choice D reason: Limiting sun exposure and wearing sunscreen is important as furosemide can make the skin more sensitive to sunlight.
Correct Answer is C
Explanation
Choice A reason: Air embolism is a potential complication during hemodialysis, but it would likely present with more acute symptoms such as chest pain or difficulty breathing.
Choice B reason: Septicemia would typically present with fever and hypotension, not necessarily with headache, nausea, and restlessness.
Choice C reason: Dialysis disequilibrium syndrome can occur after hemodialysis, especially after the first treatment, and is characterized by symptoms such as headache, nausea, and restlessness.
Choice D reason: Peritonitis is a complication associated with peritoneal dialysis, not hemodialysis.
