Urinary System Questions Questions
Question 1 of 5
All of the following substances cause urinary retention EXCEPT
Correct Answer: D
Rationale: Beta-blockers don't cause retention may relax detrusor (e.g., opposite alpha-agonists), unlike methamphetamines/ephedrine (sympathomimetic, sphincter tone) and cogentin (anticholinergic, detrusor inhibition). Lack of retention distinguishes beta-blockers, key to drug effects, unlike obstructive agents.
Question 2 of 5
All the following are true about Proteus sp. EXCEPT:
Correct Answer: B
Rationale: Proteus causes UTI, is urease positive, and swarms, but is Gram-negative not Gram-positive. This corrects bacteriology, key for infection treatment, contrasting with Gram-positive misidentification.
Question 3 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.
Question 4 of 5
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.
Question 5 of 5
With respect to sodium re-absorption:
Correct Answer: D
Rationale: Sodium reabsorption occurs in PCT (~70%), loop (ascending), and DCT (regulated) all apply. This encompasses Na+ handling, key for fluid balance, contrasting with single-segment focus.
