Questions About The Urinary System Questions 
            
        Question 1 of 5
The 'diluting segment' of the nephron is:
Correct Answer: C
Rationale: Ascending limb of Henle dilutes filtrate (NaCl reabsorption, water impermeable) not PCT, descending (concentrates), or collecting duct (ADH-dependent). This specifies diluting site, key for urine formation, contrasting with concentrating segments.
Question 2 of 5
A patient with gout has recently been started on allopurinol and is undergoing dose titration. What laboratory test should be monitored at monthly follow-up visits during this period?
Correct Answer: B
Rationale: Allopurinol reduces uric acid; monitoring serum uric acid assesses efficacy not urinalysis (stones), creatinine (kidney), AST (liver), or none. This specifies gout management, key for therapy adjustment, contrasting with renal/liver focus.
Question 3 of 5
Which of the following statements concerning the kidneys is false?
Correct Answer: D
Rationale: Kidneys are retroperitoneal, have 8-15 pyramids, distinct cortex/medulla, but span T12-L3 not L3-L5. This corrects positioning, vital for anatomy, contrasting with true traits.
Question 4 of 5
The tuft of capillaries in the renal corpuscle is called the
Correct Answer: B
Rationale: Glomerulus is the capillary tuft in the corpuscle not podocytes (cells), calyx, pyramid, or sinus. This defines filtration site, critical for GFR, contrasting with other terms.
Question 5 of 5
Which part of the urinary system is not completely retroperitoneal?
Correct Answer: C
Rationale: Bladder is partially peritoneal (superior covered) not kidneys, ureters (retroperitoneal), or nephrons (within kidney). This corrects position, vital for anatomy, contrasting with full retroperitoneal parts.
