What is the primary reason for decreased urine output in early burn shock?
Show answer and explanation
Correct answer: Reduced renal perfusion from hypovolemia and high vascular resistance
In burn shock, hypovolemia and vasoconstriction reduce renal blood flow, leading to oliguria despite preserved renal structure in the very early phase.
