    Phlebotomy Exam Prep 6, Vein Palpation and Patient Assessment
    May 3 2026
    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: - Always use your index finger for palpation, as your thumb has its own pulse that can be confused with an artery. - A suitable vein feels bouncy and firm, unlike a hard, cord-like sclerosed vein which should be avoided. - A distinct pulsating sensation indicates an artery, a critical site to avoid during venipuncture. - Never draw from sites with hematomas, extensive scarring, edema, or where an IV line was recently placed. - Proper vein anchoring involves using your thumb to pull the skin taut 1-2 inches below the site to prevent the vein from rolling.

    Apr 30 2026
