Final answer:
If extravasation is noticed at the injection site, the best course of action is to stop the injection immediately and assess the situation. Applying cold compresses and seeking medical advice are important steps for managing extravasation.
Step-by-step explanation:
If extravasation is noticed at the injection site, the best course of action is to stop the injection immediately. Extravasation occurs when a medication or solution intended for intravenous administration leaks into the surrounding tissues instead. This can cause local tissue damage and potential complications. By stopping the injection, the further leakage of the medication or solution can be prevented.
After stopping the injection, it is important to assess the extent of extravasation and the potential harm it may cause. Applying cold compresses (not ice) to the area can help reduce swelling and minimize tissue damage. Additionally, notifying a healthcare professional or the appropriate medical personnel is crucial for further evaluation and management.
