NCCPA Nephrology CAQ Examination Practice Test
Nephrology practice questions address kidney function, chronic kidney disease, fluid and electrolyte disorders, and urinary tract problems. Cases may ask you to interpret laboratory and urine findings, connect symptoms to renal mechanisms, and identify complications involving glomerular disease, obstruction, or transplantation.
Exam overview
About the NCCPA Nephrology CAQ Examination Exam
Clinical reasoning in nephrology links changes in estimated glomerular filtration rate, albuminuria, serum electrolytes, acid-base status, and urinalysis to likely causes and consequences. Decisions can involve distinguishing diabetic kidney disease from another renal process, recognizing glomerular patterns such as IgA-associated hematuria, and assessing risks from nephrotic syndrome or urinary obstruction. Management concepts include reducing phosphate absorption, evaluating suspected infection in a kidney transplant recipient, and correcting chronic hyponatremia at a safe rate. Questions may also test recognition of tubular dysfunction, kidney-related effects of tobacco exposure, and symptom evaluation in chronic kidney disease. Apply findings in context: identify the physiologic process, determine what complication requires attention, and select an appropriate next diagnostic or management step.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A patient with chronic kidney disease and persistent albuminuria is counseled to avoid tobacco use. Which kidney-related benefit is most consistent with this advice?
Show answer
Correct answer: ATobacco use is associated with cardiovascular harm and may contribute to kidney disease progression. Smoking cessation is an important component of risk reduction, but it does not reverse established scarring or eliminate the need for ongoing monitoring and other treatment.
A patient with a kidney transplant develops fever, dysuria, and pyuria. Which diagnostic step is generally appropriate to evaluate for a urinary infection?
Show answer
Correct answer: AUrinary infection is an important consideration in a transplant recipient with these symptoms. Urine culture helps identify the organism and guide treatment; immunosuppression changes or rejection diagnoses should not be based on pyuria alone.
A patient with chronic kidney disease has a persistently elevated serum phosphate despite dietary counseling. Which medication strategy can reduce intestinal phosphate absorption when taken with meals?
Show answer
Correct answer: APhosphate binders act in the gastrointestinal tract to reduce absorption of dietary phosphate and are generally taken with meals. Choice of agent depends on the patient’s calcium balance and other clinical factors.
A patient with recurrent urinary tract infections and unilateral hydronephrosis has a ureteral stone obstructing urine flow. Which mechanism can lead to kidney injury if the obstruction persists?
Show answer
Correct answer: AObstruction raises hydrostatic pressure in the collecting system and upstream tubules. Persistent pressure can lower net filtration and cause obstructive kidney injury; timely relief is important when clinically indicated.
A patient with chronic kidney disease has persistent itching and dry skin without a new rash. Which initial general measure is most appropriate while evaluating potential contributing factors?
Show answer
Correct answer: ADry skin can contribute to pruritus in chronic kidney disease. Gentle skin care, regular emollients, and avoiding hot prolonged bathing are reasonable supportive measures while assessing other causes and considering additional treatment if symptoms persist.
A patient has recurrent episodes of visible hematuria that begin within a day of an upper respiratory infection. Kidney biopsy shows mesangial IgA deposition. Which diagnosis best accounts for this presentation?
Show answer
Correct answer: AIgA nephropathy commonly causes episodic hematuria occurring during or shortly after a mucosal infection. Mesangial IgA deposition supports the diagnosis.
A patient with nephrotic syndrome develops unilateral leg swelling and pain. Which complication should be considered because of the underlying hypercoagulable state?
Show answer
Correct answer: ANephrotic syndrome causes urinary loss of anticoagulant proteins and changes in coagulation factors, increasing thrombotic risk. New unilateral leg swelling and pain warrant assessment for deep venous thrombosis.
How to use this practice test
The free US Practice Tests bank contains 50 published questions for this exam. Each practice session presents up to 20 random questions, with results shown after the session. Use the results to identify which renal patterns or clinical decisions need further review, such as electrolyte interpretation, glomerular disease, or transplant infection evaluation.
Preparation tips
- Practice interpreting albuminuria, estimated glomerular filtration rate, urinalysis, and serum chemistry together rather than treating each finding in isolation.
- Review how nephrotic syndrome, persistent urinary obstruction, and transplant-related infection can lead to distinct complications and diagnostic priorities.
- Work through electrolyte and acid-base cases, including safe correction principles for chronic hyponatremia and clues to proximal tubular dysfunction.
- Compare hematuria patterns associated with glomerular disease, and note when atypical features in a patient with diabetes suggest another kidney diagnosis.
- For chronic kidney disease management questions, connect the intervention to its mechanism, such as taking phosphate binders with meals to reduce intestinal absorption.
