What action should a nurse take if a patient shows signs of allergic reaction?

When a patient exhibits signs of an allergic reaction, the nurse's priority should be to stop the medication that is suspected to be the cause of the reaction. This action prevents further exposure to the allergen and minimizes the risk of exacerbating the reaction.

After stopping the medication, it is crucial to assess the patient's symptoms to determine the severity of the allergic reaction. Symptoms might range from mild, such as itching or hives, to severe, such as difficulty breathing or anaphylaxis. A thorough assessment helps in evaluating the situation and deciding on the next steps.

Notifying the healthcare provider is essential because they may need to initiate further interventions, such as ordering medications like corticosteroids if the reaction is severe, or managing the patient’s care in a particular way based on the assessment results. This approach aligns with nursing protocols that prioritize patient safety and prompt action in response to potential medication-related problems.

This comprehensive response ensures that the nurse addresses the patient's immediate needs while collaborating with the healthcare team for ongoing care, reflecting the critical thinking necessary in nursing practice.
