If a nurse observes a reaction, the following steps should be taken:
1. Immediate Action: Provide immediate care to alleviate the reaction if possible, such as administering antihistamines for an allergic reaction. 2. Notify the Physician: Inform the attending physician or a healthcare provider about the observed reaction. 3. Document the Incident: Record the reaction, interventions provided, and the patient's response in the medical record. 4. Reassess the Patient: Continuously monitor the patient to ensure the reaction is resolving and no new symptoms are developing. 5. Educate the Patient: Inform the patient and their family about the reaction and any necessary follow-up care.
