The triangular area of the urinary bladder between the two ureters posteriorly and the urethra anteriorly is the

Correct Answer: D

Rationale: Trigone is the bladder's triangular area (ureters to urethra), not sphincters or muscle (mislisted as D). This defines bladder base, vital for anatomy, contrasting with control structures.

Correct Answer: D

Rationale: Men with UTI need 10-14 days of treatment higher risk of complicated infection (e.g., prostate involvement), requiring longer courses. 3-5 days suit uncomplicated female cystitis insufficient here. 7 days is intermediate under-treats potential complexity. 10-14 days distinguishes it, critical for male UTI clearance, unlike shorter female-focused durations.

Correct Answer: A

Rationale: Torted appendix testis needs only analgesia self-limiting, resolves with pain control (e.g., NSAIDs), correct. Antibiotics are unnecessary no infection. Surgery isn't mandatory rarely needed. Local anesthetic isn't standard impractical. Analgesia's sufficiency distinguishes it, key to conservative management, unlike infection, surgical, or invasive errors.

Correct Answer: B

Rationale: Non-contrast CT is the choice for renal hematuria detects stones, masses, trauma (~95% sensitivity), fast/accurate. IVP (contrast) is outdated less sensitive. Angiography targets vessels not broad hematuria. Ureteroscopy is invasive diagnostic, not first-line. CT's versatility distinguishes it, key to hematuria workup, unlike older, specific, or procedural options.

Correct Answer: D

Rationale: Aiming for pH <6 isn't treatment for rhabdomyolysis ATN alkalinization (pH >6.5) prevents myoglobin casts, incorrect. Hyperkalemia correction cardiac safety, true. Saline for hypovolemia restores perfusion, correct. Diuretics (furosemide/mannitol) flush tubules standard. Acidic goal distinguishes the error, key to myoglobin management, unlike supportive principles.
