Which description best matches decompensated shock?

• A. Hypotension, altered LOC, weak/absent pulses
• B. Tachycardia, pale cool clammy skin, anxiety, normal BP
• C. Severe acidosis leading to organ failure
• D. Unstable vitals, major bleeding, airway compromise

Answer: (A)

Decompensated shock occurs when the body's compensatory mechanisms can no longer preserve adequate perfusion. The hallmark is hypotension with signs of poor organ perfusion, such as altered mental status from cerebral hypoperfusion and weak or absent peripheral pulses due to reduced cardiac output. This pattern shows that the body has progressed past early compensation into true decompensation. In compensated shock, you’d expect a normal blood pressure with tachycardia and cool, clammy skin, indicating the body is still maintaining perfusion. The other options describe either an earlier stage, a downstream consequence, or unrelated instability, rather than the characteristic pattern of decompensation.
