Renal System Questions Questions
Question 1 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.
Question 2 of 5
The nurse is caring for a patient who had a brush biopsy 12 hours ago. The presence of what assessment finding should prompt the nurse to notify the physician?
Correct Answer: C
Rationale: A fever of 100.2°F (C) post-biopsy suggests infection, warranting physician notification. Hematuria (A) and colic (B) are expected, and IV infiltration (D) is minor, making C the critical finding.

Question 5 of 5
A patient is scheduled for a CT scan of the abdomen with contrast. The patient has a baseline creatinine level of 2.3 mg/dL. In preparing this patient for the procedure, the nurse anticipates what orders?
Correct Answer: B
Rationale: Radiocontrast-induced nephropathy is a major cause of hospital-acquired acute kidney injury. Baseline levels of creatinine greater than 2 mg/dL identify the patient as being high risk. Preprocedure hydration and prescription of acetylcysteine (Mucomyst) the day prior to the test is effective in prevention. The nurse would not monitor the patients electrolytes every hour preprocedure. Nothing in the scenario indicates the need for hemodialysis. A creatinine clearance is not necessary prior to a CT scan with contrast.
