Renal System Questions Questions
Question 1 of 5
When the nurse is caring for a patient who has had left-sided extracorporeal shock wave lithotripsy, which assessment finding is most important to report to the health care provider?
Correct Answer: D
Rationale: A drop in urine output (D) post-lithotripsy suggests obstruction from stone fragments, a serious complication needing prompt reporting. Hematuria (A), pain (B), and bruising (C) are expected, but reduced output is critical, making D most important.
Question 2 of 5
The nurse is caring for a patient who is scheduled for a cystoscopy with basket (C&P) extraction of a stone. What is the most important postoperative care after this surgery for the nurse to provide?
Correct Answer: A
Rationale: Measuring urine output (A) post-C&P ensures no retention from meatal swelling, a key concern. Weights (B) and AKI (C) are secondary, and limiting fluids (D) contradicts encouraging intake, making A the priority care.
