Questions About The Urinary System Questions
Question 1 of 5
Which association is NOT correct?
Correct Answer: D
Rationale: Medullipin I (hypotensive) isn't linked to peritubular capillary endothelium, unlike PCT (brush border), bladder (transitional), DCT (macula densa), and afferent arterioles (renin). This corrects renal associations, key for physiology, contrasting with true pairings.
Question 2 of 5
Which of the following is NOT a character of intraglomerular mesangial cell?
Correct Answer: C
Rationale: Mesangial cells are between capillaries, within lamina, phagocytic, and maintain it not part of JGA (JG cells, macula densa). This corrects mesangial role, key for glomerular function, contrasting with JGA involvement.
Question 3 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 4 of 5
Urethritis is caused by all EXCEPT:
Correct Answer: C
Rationale: Urethritis involves gonococci, Mycoplasma, and Ureaplasma not S. aureus (skin/UTI). This distinguishes urethritis pathogens, key for STD treatment, contrasting with non-urethral bacteria.
Question 5 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.
