What is a common risk associated with central venous catheters?

Infection and thrombosis are indeed significant risks associated with central venous catheters (CVCs). CVCs are inserted into large veins to administer medications, fluids, and sometimes for the collection of blood samples. Because these catheters remain in place for extended periods, there is a heightened risk of infection, particularly at the insertion site or along the catheter tract. Biofilm formation on the catheter surface can lead to the colonization of bacteria, increasing the likelihood of bloodstream infections.

Thrombosis refers to the formation of a blood clot inside the catheter or the surrounding veins. The presence of a foreign body like a CVC can trigger a localized inflammatory response, making thrombus development more likely, which may lead to complications such as vein occlusion or even embolism.

Other options do not accurately reflect the risks associated with CVCs. While sterilization is critical for preventing infection, not all infections result from improper sterilization alone. Furthermore, CVCs are versatile and used for various medical interventions, not solely blood transfusions. Lastly, compared to peripheral intravenous (IV) lines, CVCs carry a greater risk profile due to their invasive nature and the prolonged duration they typically remain in place, making the claim of little to
