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: - Apply tourniquets 3-4 inches above the venipuncture site for optimal vein distention. - Never leave a tourniquet on for more than 60 seconds to avoid the complication of hemoconcentration. - Prolonged application falsely elevates specific analytes, including potassium, calcium, and total protein. - Always release the tourniquet before withdrawing the needle to prevent the formation of a hematoma. - Use single-patient-use, disposable tourniquets to adhere to infection control standards and prevent cross-contamination.
