What type of catheter is ideal for long-term medication delivery?

• A. Swan-Ganz catheter
• B. Implanted port
• C. Intra-arterial cannula
• D. Central venous access device

Answer: (B)

The implanted port is designed specifically for long-term medication delivery, making it the ideal choice for patients requiring frequent or continuous access to their bloodstream over extended periods. This type of catheter is surgically placed under the skin and provides a reliable and secure way to administer medications, fluids, or blood products without the need for repeated needle sticks.

Implanted ports also minimize the risk of infection compared to other types of catheter systems, as they are completely internal and covered by the skin. This makes them particularly suitable for patients undergoing chemotherapy, requiring long-term intravenous therapy, or those needing frequent blood draws.

In contrast, options like the Swan-Ganz catheter and intra-arterial cannula serve more specialized or temporary purposes, such as monitoring cardiac function or providing access to arterial blood flow, respectively. Similarly, while a central venous access device can be used for long-term access, it may not offer the same level of comfort and reduced infection risk as an implanted port when treatment duration is expected to be extensive.
