Which is a characteristic of a PICC line compared to a peripheral IV?

• A. Short-term use
• B. Long-term treatment
• C. Requires large blood supply
• D. Hard to assess

Answer: (B)

The main idea here is long-term venous access. A PICC line is placed to provide reliable IV access for extended periods, typically weeks to months, so it’s suited for long-term therapies such as prolonged antibiotics, chemotherapy, or total parenteral nutrition. Peripheral IVs, by contrast, are intended for short-term use and require frequent reinsertion if therapy needs to continue. The other options don’t capture this distinction: a PICC isn’t defined by needing a large blood supply, and while PICCs do require careful maintenance, “hard to assess” isn’t what distinguishes them from peripheral IVs. Therefore, long-term treatment is the characteristic that sets a PICC line apart.
