Which noninfectious harm can occur with the use of a CVC?

The correct answer highlights venous thrombosis as a significant noninfectious harm that can arise from the use of a central venous catheter (CVC). This condition occurs when a blood clot forms in a vein, often in the legs, but it can also occur in the veins where the catheter is placed. The presence of a CVC can disrupt normal blood flow and predispose patients to the development of thrombosis due to static blood flow and irritation of the vessel wall by the catheter.

In contrast, pocket site infection, contamination at insertion, and hematogenous spread are related to infectious complications associated with CVC use. While these complications are serious and deter safe catheter management, they do not fall under the category of noninfectious harms. Understanding that venous thrombosis is not caused by an infectious organism but rather by the mechanical aspect and the presence of the catheter itself is critical for nursing professionals managing patients with CVCs. This distinction helps in focusing on prevention strategies that target thromboembolic events, such as monitoring for signs of thrombosis and implementing appropriate care protocols.
