No, a peripheral IV (PIV) is not a PICC line. While both deliver fluids and medications, they differ significantly in placement and purpose:
Why can't you draw blood from a peripheral IV?
Drawing blood from an existing peripheral IV (PIV) is generally discouraged because the negative pressure required to pull blood can collapse the soft plastic catheter, cause the IV to fail prematurely, and ruin the sample.

PIVCs should be used for short-term IV therapies (up to 7 days). PIVCs should not be used if oral treatment is available.
How to insert a peripheral cannula?

Fluid Leakage and Cross-Contamination: Improper sealing or wear and tear can lead to fluid leakage, compromising procedure sterility and increasing contamination risks.
Can nurses cannulate?
Yes, nurses can cannulate. In fact, peripheral intravenous cannulation is a core clinical competency for many nurses, though performing it typically requires additional specialized training, practical supervision, and formal competency sign-offs beyond basic nursing education.
