Which is not a principal of treatment in ATN due to rhabdomyolysis?

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.

Correct Answer: A

Rationale: Treating with cefixime/azithromycin (STD regimen) and discharging is least indicated acute scrotal pain suggests torsion, a surgical emergency, not epididymitis. Radionuclide scan/Doppler confirm torsion useful. Manual detorsion relieves attemptable. Urinalysis rules out infection relevant. Presumptive antibiotics distinguish the error, key to missing torsion, unlike diagnostic or therapeutic steps.

Correct Answer: D

Rationale: E. coli is the most common uncomplicated UTI organism ~80% (e.g., fimbriae adhesion), community-acquired leader. Chlamydia causes urethritis not bladder. Klebsiella/Proteus are less frequent complicated UTIs. E. coli's dominance distinguishes it, key to UTI microbiology, unlike STD or secondary pathogens.

Correct Answer: D

Rationale: Kidneys extend from T12 to L3, with the lower end at L3 not T11, T12, L1, or L2. This defines renal vertebral position, vital for anatomical localization, contrasting with higher or partial placements.

Correct Answer: A

Rationale: Pyonephrosis is acute pus-filled pyelonephritis with hydronephrosis not chronic or non-suppurative. This defines an urgent condition, critical for intervention, contrasting with chronic or less severe states.
