What treatment option can be instilled into a catheter to address thrombus?

Anticoagulants
Thrombolytic agents
Antibiotics
Analgesics

The correct answer is: Thrombolytic agents

The treatment option that is specifically indicated for addressing thrombus when instilled into a catheter is thrombolytic agents. Thrombolytics are medications designed to dissolve blood clots through a process called thrombolysis. They act by breaking down fibrin, the protein that forms the mesh structure of blood clots, effectively facilitating the restoration of normal blood flow in the affected vessel or catheter. In the context of catheter-related thrombus, using thrombolytic agents can alleviate complications such as catheter occlusion, which can occur when clots form at or near the catheter tip. This treatment is typically administered under specific clinical circumstances and often involves careful monitoring due to the potential risk of bleeding. Anticoagulants, while important in the management of thromboembolic disorders, do not dissolve existing clots; instead, they prevent further clot formation and are generally not used for thrombus in catheter occlusions. Antibiotics have a role in treating infections but do not address thrombus issues, and analgesics serve to relieve pain rather than treat clots. Therefore, thrombolytic agents are the most appropriate and effective choice for directly addressing thrombus in a catheter.
