What is an indicator of shock in the Tactical Field Care setting?

• A. Elevated blood pressure
• B. Rapid breathing
• C. An altered level of consciousness
• D. Cool, clammy skin

Answer: (C)

In shock, inadequate tissue perfusion quickly affects the brain, so a change in mental status is a direct and reliable sign. An altered level of consciousness—ranging from agitation or confusion to drowsiness or unresponsiveness—reflects cerebral hypoperfusion and signals that the casualty needs rapid assessment and intervention in the field. This observable change is particularly useful in Tactical Field Care because it can be detected quickly and often indicates that perfusion to vital organs is compromised. Other signs like rapid breathing or cool, clammy skin can occur with shock, but they are less specific and can vary with the type and stage of shock. Elevated blood pressure is not typical of shock; if pressure remains high, it may mean compensation is still maintaining flow or point to another issue.
