Which of the following is NOT a main type of CVAD?

• A. Tunneled catheters
• B. Non-tunneled catheters
• C. Peripheral catheters
• D. PICCs

Answer: (C)

Peripheral catheters are distinct from the main types of central venous access devices (CVADs) because they are specifically used to access veins that are situated closer to the surface of the skin, typically in the arms or hands. These catheters are generally utilized for short-term intravenous therapy and do not provide the same long-term access that CVADs do. In contrast, tunneled catheters, non-tunneled catheters, and peripherally inserted central catheters (PICCs) are all classified as central venous access devices since they are designed to provide access to a central vein, allowing for the administration of medications, fluids, or nutrients over a longer duration. Tunneled catheters are surgically implanted and tunneled subcutaneously, while non-tunneled catheters can be placed directly into the central vein. PICCs are inserted into a peripheral vein and advanced into the central venous system, serving a similar purpose as other CVADs for longer-term access.
