Multiple Choice Questions Renal System Questions
Question 1 of 5
When assessing a 30-year-old man who complains of a feeling of incomplete bladder emptying and a split, spraying urine stream, the nurse asks about a history of
Correct Answer: C
Rationale: Symptoms suggest urethral stricture, a complication of gonococcal urethritis (C). Bladder infection (A) causes dysuria, trauma (B) isn't indicated, and BPH (D) is age-related, making C the likely history.
Question 2 of 5
Which nursing action is essential for a patient immediately after a renal biopsy?
Correct Answer: C
Rationale: A pressure dressing is applied, and the patient is kept on the affected side for 30 to 60 minutes to put pressure on the biopsy side and decrease the risk for bleeding. The blood glucose and BUN/creatinine will not be affected by the biopsy. Although monitoring for hematuria is needed, there is no need for catheterization.
Question 3 of 5
The nurse is collecting data for a patient who has stress incontinence. Which of these findings would the nurse document?
Correct Answer: B
Rationale: Stress incontinence (B) involves small urine loss with increased abdominal pressure (e.g., coughing), a classic finding. Bathroom access (A) is functional, emotional stress (C) isn't typical, and sensation loss (D) is urge incontinence, making B the documentation.
Question 4 of 5
Normally, the bladder contains less than ___ mL after urination.
Correct Answer: B
Rationale: Post-void residual is normally <50 mL (B), ensuring effective emptying. 25 mL (A) is possible but not the upper limit, and 75-100 mL (C, D) suggest retention, making B the correct amount.
Question 5 of 5
The care team is considering the use of dialysis in a patient whose renal function is progressively declining. Renal replacement therapy is indicated in which of the following situations?
Correct Answer: D
Rationale: Renal replacement therapy like dialysis is indicated when ~80% of nephrons fail (D), reducing function to <20%, causing severe symptoms unmanageable by diet or drugs. Normal creatinine is 0.6-1.2 mg/dL (A is wrong), BUN 15 mg/dL (B) is normal (7-20 mg/dL), and 40% loss (C) is insufficient for dialysis, making D the threshold.
