What is a key advantage of an implanted subcutaneous port compared with external IV access?

• A. Long-term therapy with low infection risk and cosmetic discretion
• B. Requires no flushing
• C. More prone to infection than external lines
• D. Is accessed through an external tube

Answer: (A)

The key point is that implanted subcutaneous ports are designed for long-term venous access with less risk of infection and greater cosmetic discretion than external IV lines. Because the port sits entirely under the skin and only a special needle pierces the skin when access is needed, the entry site is protected from environmental exposure and physical snagging. This setup makes long-term therapies—like chemotherapy or prolonged antibiotics—more convenient and discreet, since there’s no external tubing to manage or hide.

It’s also important to recognize that these ports still require regular flushing to keep the lumen patent and prevent clotting; saying no flushing is needed would be inaccurate. Additionally, implanted ports generally have lower infection risk compared with external lines, not higher. Accessing the port is done through the skin with a needle, not through an external tube, which is why that description doesn’t fit.
