Which finding is most consistent with obstructive shock?

Which finding is most consistent with obstructive shock?

• A. JVD
• B. Clear lungs
• C. Warm dry skin
• D. Normal sensation

Answer: (A)

Obstructive shock happens when something blocks blood flow into or through the heart, so the heart can’t fill or pump effectively, leading to backup in the venous system. Jugular venous distension is the clearest sign of that backup, reflecting elevated venous pressures from impaired venous return. This pattern is common across causes like tamponade, tension pneumothorax, or massive pulmonary embolism. Lungs may be clear because the issue isn’t primarily fluid overload in the lungs, and skin is often cool from poor perfusion rather than warm from vasodilation. Normal sensation doesn’t provide information about the hemodynamics involved.
