Hematocrit level of >47% 4. Urine specific gravity of 1.027 5. Urine osmolality of >450 mOsm/kg correct answers Correct answer: 3. 4. and 5. More than half of students who answered this question in Wolters Kluwer's adaptive learning systems, powered by PrepU, answered "BUN : serum creatinine ratio of >12.1." The BUN to creatinine ratio is above 20:1 in hypovolemia due to dehydration or decreased renal perfusion and function.
