What is a primary indication for placing a PICC line?

The primary indication for placing a PICC (Peripherally Inserted Central Catheter) line is the delivery of hyperosmolar solutions. PICC lines are designed for long-term intravenous access and are typically used to administer medications, fluids, and nutrients that may be too irritating to peripheral veins. Hyperosmolar solutions, which can include total parenteral nutrition or certain chemotherapeutic agents, require a central line such as a PICC to minimize the risk of phlebitis and ensure safe delivery.

In contrast, routine blood pressure monitoring does not require a central venous access device like a PICC line, as this can be accomplished with standard non-invasive or invasive arterial lines. Transient intravenous access refers to short-term access, which is usually addressed with peripheral IV catheters rather than a more complex PICC line. Catheterization of the bladder is unrelated to intravenous access and pertains to urological procedures; thus, it does not involve the use of a PICC line.
