What action should a nurse take if a patient exhibits difficulty breathing during IV therapy?

In the scenario where a patient exhibits difficulty breathing during IV therapy, notifying a physician immediately is the appropriate action to take. This step is critical because difficulty breathing could indicate a serious complication, such as an allergic reaction or fluid overload, which may require immediate medical intervention. The physician can assess the situation more thoroughly and decide on the necessary treatment or intervention to ensure patient safety.

While administering oxygen may seem beneficial, it should be done under the guidance of a physician, especially since the cause of the respiratory distress is not yet determined. Increasing the IV flow rate or changing the IV site could exacerbate the situation and might not address the underlying cause of the respiratory distress. It's vital to prioritize patient safety by seeking professional medical help in urgent situations like this.
