What is the first stage of shock according to the material?

• A. Compensatory
• B. Decompensatory
• C. Irreversible
• D. Progressive

Answer: (A)

The first stage of shock is compensated (nonprogressive) shock. In this early phase the body activates mechanisms to keep blood flowing to essential organs despite reduced circulating volume. The heart rate rises and blood vessels constrict, helping to maintain blood pressure initially. Signs can be subtle: the person may feel anxious or restless, skin can be cool and clammy, and capillary refill or peripheral pulses may be slower, yet perfusion to vital organs is preserved. Because these responses keep circulation adequate, this stage is typically reversible with prompt care—stopping bleeding, keeping the person flat, keeping them warm, and obtaining help. If these compensatory efforts fail, the condition advances to decompensated (progressing) shock with falling blood pressure and worsening signs, and later stages involve irreversible organ damage.
