Final answer:
The main complication of fibrinolytic therapy is the increased risk of bleeding and hemorrhage, as it speeds up the degradation of blood clots by converting plasminogen to plasmin.
Step-by-step explanation:
The complication that can arise from fibrinolytic therapy is C) Increased risk of bleeding and hemorrhage. Fibrinolytic therapy involves the use of thrombolytic agents, such as tissue plasminogen activator, to accelerate the degradation of blood clots. This process enhances the conversion of plasminogen to plasmin which then breaks down fibrin clots. While this is crucial in situations like a thrombotic stroke and helps in restoring normal blood flow to the affected area, it also increases the patient's risk for bleeding complications as the normal clotting mechanisms are interrupted.
