How should a nurse respond to a client showing signs of air embolism during an IV infusion?

When a client demonstrates signs of an air embolism during an IV infusion, the nurse's first priority is to stop the infusion and position the client appropriately to minimize complications. Stopping the infusion halts the introduction of any further air into the circulatory system, which is critical in preventing worsening of the embolism.

Positioning the client correctly is equally important; the ideal position in the case of an air embolism is typically on the left side with the head down. This positioning helps trap the air in the right atrium and reduces the risk of the air moving into the pulmonary circulation, thus protecting vital organ function and allowing the air to be gradually reabsorbed or removed by the body.

High-flow oxygen administration may be beneficial in supporting the client's respiratory status following an embolism, but the urgent need is to stop the infusion and reduce further risk. Replacing the IV system immediately does not address the immediate threat posed by the air already present in the system and may delay necessary interventions. Turning the client to their right side is contraindicated as it could facilitate the air moving towards the right ventricle and into the pulmonary artery, thus increasing the risk of pulmonary complications.

Thus, stopping the infusion and positioning the client correctly are the critical first
