Renal System Questions Questions
Question 1 of 5
Natriuretic hormone is produced by cells in the kidneys.
Correct Answer: B
Rationale: Atrial natriuretic peptide (ANP), a natriuretic hormone, is produced by the heart's atria, not kidneys (B), to reduce sodium and volume. Kidneys produce renin and erythropoietin, making False the correct answer over True (A).
Question 2 of 5
When planning teaching for a patient with benign nephrosclerosis the nurse should include instructions regarding
Correct Answer: A
Rationale: Nephrosclerosis causes hypertension (A), so monitoring BP is key. Weights (B) and I&O (C) are for renal failure, not typical here, and anticoagulants (D) aren't used, making A the focus.
Question 3 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 4 of 5
A female patient with a suspected urinary tract infection is to provide a clean-catch urine specimen for culture and sensitivity testing. What should the nurse do to obtain the specimen?
Correct Answer: B
Rationale: This answer describes the technique for obtaining a clean-catch specimen. The answer beginning, “insert a short, small, ‘mini' catheter attached to a collecting container†describes a technique that would result in a sterile specimen, but a health care provider's order for a catheterized specimen would be required. Using Betadine before obtaining the specimen might result in suppressing the growth of some bacteria. The technique described in the answer beginning “have the patient empty the bladder completely†would not result in a sterile specimen.
Question 5 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.
