What is the Earliest Consequence of a Decreased GFR,as in Shock

Question

What is the earliest consequence of a decreased GFR,as in shock?
A) Urinary retention
B) Glucosuria
C) Albuminuria
D) Oliguria

Accepted Answer

Oliguria, or a decreased urine output, is the earliest consequence of a decreased GFR in conditions such as shock. This is because as blood volume and blood flow to the kidneys decrease, less plasma is filtered by the glomeruli, leading to reduced urine output. Choices A, B, and C are not typically seen as early consequences of decreased GFR.
