Lesson 1Injection technique to minimize extravasation: vein selection, tourniquet use, aspiration check, flushing, and securing injection siteThis lesson covers vein injection ways to reduce leaking, including vein choice, band use, pull-back check, washing, and site holding, and explains spotting, writing down, and handling leak events.
