Which of the following catheters are commonly used for central vascular access?

The use of Hickman and Groshong catheters for central vascular access is based on their design and functionality. Hickman catheters are modified CVCs (central venous catheters) with a single or double lumen that allows for long-term access to the central venous system. They are often used in patients requiring frequent venous access for chemotherapy, intravenous medications, or fluids. The Hickman catheter is notable for its ability to remain in place for extended periods, which is beneficial for patients needing ongoing treatment.

Groshong catheters, on the other hand, are also designed for long-term central vascular access and feature a unique valve that reduces the risk of air embolism and thrombosis. This prevents blood from flowing back into the catheter when not in use and facilitates easy access for injections or infusions.

Together, these two catheter types are widely recognized in clinical practice for their durability and effectiveness in managing central vascular access, making them the correct choice for this question. The other options include catheters not typically used for central vascular access, such as Foley catheters, which are primarily designed for urinary drainage, and CVA, which may refer to conditions or terminology not directly related to a specific type of central
