Which three-letter abbreviation represents a thrombolytic medication used to break apart clots?

The three-letter abbreviation that represents a thrombolytic medication used to break apart clots is TPA, which stands for tissue plasminogen activator. TPA is a critical medication in the management of acute ischemic stroke and certain types of myocardial infarction by promoting the breakdown of fibrin, a key component of blood clots. Administering TPA can significantly improve outcomes by restoring blood flow to affected areas, especially when given within a narrow time window from the onset of symptoms.

Other abbreviations such as ABC, XYZ, and ASH do not correspond to recognized thrombolytic agents or treatments in clinical practice. Thus, TPA is the correct choice associated with thrombolysis and clot management.
