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

Rationale: A. Continue the infusion and reassess in 10 minutes is incorrect because hives and wheezing are signs of an acute allergic reaction or anaphylaxis. Continuing the infusion could worsen the reaction and become life-threatening, delaying emergency intervention. B. Stop the infusion and initiate facility emergency response per policy is correct. The first action is to stop the medication immediately to prevent further exposure. Then, the nurse should follow emergency protocols, which may include calling a code, administering epinephrine, oxygen, and other emergency interventions, and monitoring vital signs. This sequence addresses the most immediate threat to the patient’s airway, breathing, and circulation. C. Document and leave the room to notify the provider later is incorrect because delaying action could result in rapid deterioration. Immediate response is essential in potential anaphylaxis. D. Flush the line forcefully is incorrect because flushing would push more of the offending medication into the bloodstream, worsening the reaction and potentially causing cardiovascular collapse or respiratory distress.
