Your patient is in shock, but the body's defense mechanisms are currently able to maintain adequate circulation. This is called ___________.

• A. Compensated
• B. Irreversible
• C. Decompensated
• D. Late

Answer: (A)

In shock, the body can activate defenses to preserve blood flow to vital organs. When those compensatory mechanisms are able to maintain adequate circulation, the situation is described as compensated shock. The body raises heart rate and strengthens pumping, constricts some blood vessels to maintain blood pressure, and shifts fluids to support preload, all to keep organs like the brain and heart perfused.

If these defenses fail, perfusion worsens and you enter decompensated shock, where blood pressure falls and organs begin to suffer. Irreversible shock refers to damage so extensive that recovery is unlikely even with treatment. The term late isn’t a precise stage used to describe shock progression.
