Renal System Questions Questions
Question 1 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 2 of 5
A client with phobic disorder avoids crowded places. The nurse recognizes this behavior as an example of:
Correct Answer: B
Rationale: Avoidance of crowded places is characteristic of agoraphobia.
Question 3 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.
Question 4 of 5
The nurse contributes to the plan of care for a patient having an intravenous pyelogram. Which intervention should be included?
Correct Answer: B
Rationale: Monitoring creatinine detects contrast-induced kidney damage.
Question 5 of 5
Match the description 'Passively permeable to water' to the structure: A) proximal convoluted tubule, B) descending limb of the nephron loop, C) collecting duct, D) ascending limb of the nephron loop.
Correct Answer: B
Rationale: The descending limb (B) is passively permeable to water, allowing concentration via medullary osmosis. The proximal tubule (A) uses active sodium transport, collecting duct (C) requires ADH, and ascending limb (D) is impermeable, making B correct.
