Most shock states look the way learners expect: pale, cool, clammy skin, a thready pulse, and a client who looks unwell before the pressure falls. Distributive shock frequently looks the opposite. The client may be warm, flushed and dry, with a full bounding pulse, while their blood pressure is dangerously low. That mismatch is not a curiosity — it is the reason distributive shock is missed. A nurse trained to associate shock with cold peripheries can look at warm hands and be reassured by exactly the finding that should raise concern. Distributive shock is inadequate tissue perfusion caused by loss of vascular tone. Volume has not been lost and the pump has not failed; the vessels have dilated so widely that the same volume no longer fills them under adequate pressure. Three causes account for nearly all cases: overwhelming infection, severe allergic reaction, and loss of sympathetic outflow after spinal cord injury. The nurse's task is to recognize the pattern despite its misleading surface, to understand why volume alone is insufficient, and to know which cause is in front of...
