Decompensated shock is characterized by…

• A. BP rising
• B. BP stable
• C. No symptoms
• D. BP falling, late shock

Answer: (D)

Decompensated shock means the body’s compensatory mechanisms can no longer maintain adequate blood flow, so arterial pressure falls. This hypotension is a late sign of shock, reflecting worsening perfusion to organs. Early stages often keep blood pressure normal or even elevated due to tachycardia and vasoconstriction, so a falling BP identifies the transition into decompensation. Additional clues include mental status changes, cool/clammy skin, and reduced urine output, all signaling diminished perfusion.
