Urinary System Questions Questions
Question 1 of 5
Juxtaglomerular cells are:
Correct Answer: D
Rationale: Juxtaglomerular (JG) cells secrete renin, not mesangial (support), phagocytic, lacis (extraglomerular), or Na-sensitive (macula densa). This identifies JG cells' role in RAAS, critical for blood pressure regulation, contrasting with other glomerular components' functions.
Question 2 of 5
Hospital acquired UTI is most commonly caused by EXCEPT:
Correct Answer: A
Rationale: Nosocomial UTIs involve Pseudomonas, Klebsiella, and Enterococcus not S. saprophyticus (community-acquired). This distinguishes hospital pathogens, key for infection control, contrasting with outpatient bacteria.

Membranous glomerulopathy and post-streptococcal glomerulonephritis are similar in that they both:
Correct Answer: D
Rationale: Both feature immune complex deposits not self-limiting (membranous chronic), nephrotic (membranous mainly), pediatric (PSGN mainly), or post-infectious (PSGN only). This identifies shared pathology, key for glomerulonephritis, contrasting with clinical differences.
