In cardiogenic shock, which sign indicates reduced renal perfusion?

• A. Decreased urine output
• B. Polyuria
• C. No change in urine output
• D. Frequent urination

Answer: (A)

In cardiogenic shock, the heart’s reduced pumping lowers blood flow to the kidneys, so the kidneys respond by conserving fluid and producing less urine. This oliguria, or decreased urine output, is a classic sign of reduced renal perfusion. Polyuria or frequent urination would indicate more urine production, not less, and no change would not reflect the hypoperfusion happening to the kidneys. So the best indicator of reduced renal perfusion in this context is decreased urine output.
