A client develops hives and wheezing during an IV medication infusion. The LVN should first:

Rationale: A. Continuing the infusion and reassessing later is unsafe because the client is showing signs of a severe allergic reaction, possibly anaphylaxis. Delaying intervention can lead to rapid deterioration and life-threatening complications. B. Documenting and leaving the room to notify the provider later is inappropriate. Immediate action is required in the presence of hives and wheezing, which indicate a systemic allergic reaction affecting the airway and circulation. Delaying care could be fatal. C. Stopping the infusion and initiating the facility emergency response is correct. The first priority is to prevent further exposure to the allergen by stopping the IV, while simultaneously activating emergency protocols, which may include calling a rapid response team, administering emergency medications such as epinephrine, and providing airway support. This action prioritizes client safety and follows emergency standards for allergic reactions. D. Flushing the line forcefully is contraindicated because it would push the allergen further into the client’s bloodstream, worsening the reaction.
