After stopping an IV antibiotic due to a client's allergic reaction, what is the nurse’s priority action?

In the scenario of an allergic reaction to an IV antibiotic, the priority action for the nurse is to assess the client's respiratory status. Allergic reactions can lead to serious complications, including respiratory distress due to swelling of the airways, bronchospasm, or anaphylaxis, which is a severe and potentially life-threatening reaction.

By assessing respiratory status first, the nurse can quickly determine if there are any signs of obstruction, difficulty breathing, or decreased oxygenation, which requires immediate intervention. This assessment may include checking the client's respiratory rate, effort, and lung sounds, as well as evaluating oxygen saturation levels. Prompt recognition of any respiratory compromise allows for timely interventions such as administering oxygen, positioning the patient appropriately, or preparing for emergency treatments if needed.

While notifying the primary healthcare provider, taking the client's blood pressure, and obtaining pulse oximetry are also important steps in managing the overall situation, the immediate need to evaluate and address potential respiratory issues takes precedence in ensuring the client's safety and well-being.
