## Resource

This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - The primary rule is to always use the opposite arm of a running IV to prevent sample dilution and contamination. - If drawing from an IV arm is unavoidable, the nurse must pause the infusion for at least two minutes before the draw. - The venipuncture site must always be located distal to, or below, the IV cannula insertion point. - A discard tube of at least 5 mL must be drawn first to eliminate residual IV fluid before collecting patient samples. - For heparin or saline locks, a similar discard procedure is required to prevent contamination from the flush solution.
