If a client develops wheezing during intravenous vancomycin administration, what is the appropriate immediate action by the nurse?

When a client develops wheezing during intravenous vancomycin administration, the most appropriate immediate action is to stop the infusion. Wheezing can indicate an allergic reaction or hypersensitivity to the medication, potentially leading to more severe respiratory distress or anaphylaxis if not addressed promptly. Stopping the infusion removes the source of the potential allergen and allows for an immediate assessment of the client’s respiratory status.

Continuing the infusion, even at a lower rate, could exacerbate the reaction and worsen the client’s condition. It is critical to ensure the client's safety first by halting the administration of the drug. While assessing for other symptoms or calling for a respiratory therapist may be necessary steps following the cessation of the infusion, these actions should not take precedence over stopping the medication that may be causing the adverse reaction. Quick intervention is essential in managing allergic responses to medications.
