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.
