A 62-year-old man with sepsis from pneumonia receives aggressive IV fluid resuscitation. Despite 5 liters given, his blood pressure remains 88/52 mmHg, urine output is 0.2 mL/kg/hr, and serum creatinine rises from 1.0 to 2.5 mg/dL. Urine sodium is 15 mEq/L and urinary osmolality is 560 mOsm/kg. Which of the following is the most likely diagnosis?
- A)Septic shock-induced glomerulonephritis
- B)Rhabdomyolysis-induced AKI
- C)Prerenal azotemiaGABARITO
- D)Acute interstitial nephritis
- E)Acute tubular necrosis
Explicação
Prerenal azotemia is characterized by low urine sodium (<20 mEq/L) and high urine osmolality (>500 mOsm/kg), reflecting preserved tubular function and appropriate renal perfusion compensation. This patient's values are classic for prerenal AKI from persistent ... Ver explicação completa e trilha adaptativa →
