In the event of a client complaining of chest tightness and dyspnea during an IV infusion, what is the priority action by the nurse?

In situations where a client experiences chest tightness and dyspnea during an IV infusion, the priority action is to shut off the IV infusion. This is crucial because chest tightness and difficulty in breathing can indicate an adverse reaction to the medication or fluid being infused, possibly leading to serious complications such as anaphylaxis or fluid overload.

By stopping the infusion, the nurse can prevent further exposure to the potentially harmful substance while simultaneously gaining time to assess and manage the situation safely. This action helps to mitigate any risks associated with continuing the infusion in the face of alarming symptoms.

While administering oxygen, assessing vital signs, and notifying the healthcare provider are all important steps in managing the client's condition, they should occur after the IV is discontinued. Shutting off the infusion ensures that no additional medication or fluid is delivered that could exacerbate the client’s condition while the healthcare team evaluates and responds to the symptoms.
