Which statement best describes blood pressure in shock?

• A. Blood pressure always falls in shock
• B. Blood pressure sometimes rises in shock
• C. Blood pressure never falls in shock
• D. Blood pressure does not always fall in setting of shock

Answer: (D)

Blood pressure in shock is not uniformly low from the start. In the early, compensated phase, the body ramps up sympathetic drive, raising heart rate and constricting vessels to preserve perfusion. This can keep blood pressure within normal range or even temporarily higher, even though tissues are hypoperfused. Only as shock progresses and compensatory mechanisms fail does blood pressure typically drop. So the correct statement is that blood pressure does not always fall in the setting of shock—it's possible to have normal or elevated BP early, with hypotension signaling decompensation later. This helps explain why BP alone isn’t the sole gauge of shock severity.
