What is a Port-a-Cath?

• A. A subcutaneous implanted venous access device
• B. An external peripheral IV catheter
• C. A central venous catheter placed via neck vein
• D. A subcutaneous implanted venous access device; care includes sterile dressing changes, regular flushing with saline/heparin per protocol, and protection from trauma

Answer: (D)

Port-a-Cath is a subcutaneously implanted venous access device used for long-term IV therapies. It consists of a small reservoir placed under the skin, usually on the chest, connected to a catheter that reaches a central vein. The port is accessed through the skin with a special needle when therapy is needed. Care involves sterile dressing changes at the port site, regular flushing with saline and heparin per protocol to keep the line open, and protection from trauma to prevent infection or damage. This combination of an implanted device and ongoing maintenance distinguishes it from an external peripheral IV or a non-implanted central line.
