Which of the Following Substances is Given to Patients to Dissolve

Question

Which of the following substances is given to patients to dissolve blood clots?
A) vitamin K
B) tissue plasminogen activator
C) heparin
D) warfarin

Accepted Answer

Tissue plasminogen activator (tPA) is a medication given to patients to dissolve blood clots. It works by converting plasminogen to plasmin, which breaks down fibrin, the protein that makes up blood clots. Vitamin K, heparin, and warfarin are anticoagulants, but they do not directly dissolve blood clots.
