When is PIV insertion generally indicated?

Peripheral intravenous (PIV) insertion is primarily indicated for the administration of non-vesicant medications. Non-vesicants are those substances that do not cause tissue damage or irritation if they extravasate, making PIV access suitable for their administration. This allows for a safe and effective way to deliver medications and fluids while minimizing the risk of complications associated with vascular access.

When using PIV access for non-vesicant infusions, health care providers can ensure patient comfort and safety, as the risks associated with extravasation are considerably lower compared to vesicant medications, which can cause severe tissue damage. This guideline helps to maintain patient safety and optimize therapy outcomes.

The other options presented involve scenarios where PIV insertion is not generally indicated or poses higher risks. For example, using a PIV for infusions exceeding a certain duration, such as 6 days, increases the risk of complications like phlebitis or thrombosis. Infusing medications with an osmolarity greater than 900 mOsm/L also requires more secure vascular access, such as a central line, because they can irritate the veins significantly. Lastly, administering vesicants requires continuous monitoring and typically necessitates the use of a central line to mitigate the risks associated
