Which term describes the failure of multiple organ systems due to shock?

• A. Compensated Shock
• B. Multi-Organ Failure
• C. Shock
• D. Lactic Acidosis

Answer: (B)

In shock, blood flow and oxygen delivery to tissues fall below what organs need, and that can progress to dysfunction in several organ systems. When multiple organs fail due to this sustained hypoperfusion and the ensuing inflammatory response, the term used is multi-organ failure. It captures the reality that the body's response to shock can disrupt function across various vital systems—kidneys, liver, lungs, brain, and others—rather than just a single issue.

Compensated shock refers to an early stage where compensatory mechanisms keep blood pressure and perfusion adequate, so organ failure isn’t present. Shock describes the broader state of circulatory failure, not necessarily the extent of organ dysfunction. Lactic acidosis is a consequence that often accompanies shock due to anaerobic metabolism, but it describes a metabolic change, not the systemic failure of multiple organs.
