Which combination of symptoms indicates speed shock during IV therapy and what should you do?

• A. Rapid onset flushing, dizziness, chest tightness, hypotension; stop the infusion, discontinue the line, monitor and notify physician.
• B. Slow the infusion rate gradually over 30 minutes.
• C. Increase the rate to finish quickly.
• D. Discontinue all monitoring.

Answer: (A)

Speed shock happens when an IV drug or fluid enters the bloodstream too quickly, causing an abrupt surge in drug levels that can overwhelm the heart and circulatory system. The signs—rapid onset flushing, dizziness, chest tightness, and low blood pressure—fit this reaction, reflecting an immediate cardiovascular response to the sudden exposure.

The best course of action is to stop the infusion right away and discontinue the IV line, then monitor the patient and notify the physician. Halting the administration prevents any further rapid exposure, while ongoing assessment and professional guidance ensure appropriate treatment and next steps. After stopping, assess airway, breathing, and circulation, and follow protocol for stabilization and any needed escalation of care.

Why the other options aren’t appropriate in the moment: slowing the rate later would not stop the current rapid exposure, increasing the rate would likely worsen the reaction, and stopping monitoring would put the patient at risk.
