What is the primary purpose of using a dressing on a CVAD?

• A. To provide warmth to the site
• B. To decorate the insertion area
• C. To keep the insertion site clean and protect it from infection
• D. To stabilize the catheter

Answer: (C)

Using a dressing on a central venous access device (CVAD) primarily serves the critical function of keeping the insertion site clean and protecting it from infection. Maintaining a sterile and clean environment is essential in preventing the introduction of pathogens that can lead to serious complications like catheter-related bloodstream infections.

Dressing materials are designed to be both protective and breathable, allowing for the evaluation of the site while offering a barrier against contaminants. Properly applied dressings can also help in monitoring the site for signs of infection or complications without needing to remove them frequently, thus reducing the risk of exposure.

While stabilizing the catheter is an important function, it is secondary to the main goal of infection prevention. Overall, ensuring cleanliness and protection directly contributes to patient safety and the successful use of CVAD for various medical treatments.
