Which of the following statements concerning the kidneys is false?

Correct Answer: D

Rationale: Kidneys span T12-L3, not L3-L5 (false), while retroperitoneal, pyramids (8-15), and cortex/medulla are true. This corrects positioning, vital for anatomy, contrasting with true traits.

Correct Answer: C

Rationale: Acute tubulointerstitial nephritis isn't the most common renal ARF cause acute tubular necrosis (ATN) dominates (e.g., ischemia/toxins), incorrect. Pre-renal urea:creatinine rises hypoperfusion concentrates urea, true. Post-renal obstruction is less common e.g., stones rarer than ATN, accurate. Glomerulonephritis shows hematuria, pyuria, casts classic, correct. ATN's prevalence distinguishes the error, critical for ARF etiology, unlike true pre/post-renal or diagnostic statements.

Correct Answer: B

Rationale: E. coli is the most likely UTI organism ~80% of uncomplicated cases (e.g., adheres via fimbriae), dominant in community settings. Staph saprophyticus ranks second young women, ~10-15%. Pseudomonas and Klebsiella occur in complicated UTIs hospitalized/catheterized, less common. E. coli's prevalence distinguishes it, key to UTI etiology, unlike secondary or nosocomial pathogens.

Correct Answer: A

Rationale: Amiodarone causes epididymitis, not orchitis drug-induced, not infectious, distinguishing it as not epididimoorchitis (combined). Mumps virus spreads to testes classic. Pseudomonas infects epididymis/testes nosocomial. Cryptococcus (fungal) affects immunocompromised rare but true. Amiodarone's epididymal limit distinguishes it, key to etiology differentiation, unlike infectious causes.

Correct Answer: A

Rationale: Prostatitis isn't usually STD-related E. coli (enteric) dominates acute bacterial cases, incorrect. Tender/enlarged prostate classic sign, true. IV gentamicin/ampicillin for severe cases appropriate. Co-trimoxazole concentrates well effective, correct. Non-STD etiology distinguishes the error, key to bacterial prostatitis, unlike physical, severe, or treatment truths.
