What central venous access device is commonly used for long‑term pediatric chemotherapy to facilitate frequent dosing and vesicant administration?

• A. Peripheral IV catheter
• B. Implanted venous port
• C. Umbilical venous catheter
• D. Arterial line

Answer: (B)

Long-term pediatric chemotherapy relies on a durable venous access device that can be accessed repeatedly for frequent dosing and the administration of vesicants. An implanted venous port fits this need by sitting under the skin and connecting to a central vein, allowing treatment through a small hub with a non-coring needle during each session. Because it remains in place for months to years, it minimizes painful needle sticks, reduces the risk of repeated vein damage, and can be used for both regular infusions and vesicant chemotherapies. In contrast, a peripheral IV is not ideal for long-term use or vesicant administration due to limited durability and higher risk of infiltration. An umbilical venous catheter is typically a short-term option used in newborns in specific settings, not for ongoing chemotherapy, and an arterial line is for arterial monitoring, not for venous drug delivery.
