Renal System Questions Questions
Question 1 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 2 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 3 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.
Question 4 of 5
A minimum creatinine clearance of ___ mL per minute is needed to live without dialysis.
Correct Answer: B
Rationale: A minimum creatinine clearance of 10 mL/min (B) sustains life without dialysis. 5 mL/min (A) is too low, and 15-20 mL/min (C, D) exceed the threshold, making B the correct value.
