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 (collecting), or pyramid (medulla). This defines filtration site, critical for GFR, contrasting with other terms.

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.

Correct Answer: D

Rationale: 10 cm kidneys (normal size) suggest ARF CRF shrinks kidneys (<9 cm) from scarring, not chronic. Anemia (erythropoietin loss), osteodystrophy (phosphate retention), and polyuria/nocturia (tubular damage) are CRF hallmarks chronic adaptation. Normal size distinguishes ARF, key to differentiating acuity, unlike chronic signs.
