Which abbreviation denotes a four-factor prothrombin complex concentrate used to reverse anticoagulants?

Explanation:
Reversing anticoagulation quickly hinges on replacing the vitamin K–dependent clotting factors that warfarin lowers. A four-factor prothrombin complex concentrate does exactly that, delivering factors II, VII, IX, and X in a concentrated form. This lets the blood coagulate again promptly, which is crucial in emergencies or when rapid reversal is needed. That’s why the four-factor PCC abbreviation is the best match: it specifies a product that provides all four needed factors for immediate effect. Fresh frozen plasma can also reverse anticoagulation but in a less efficient way—it's less concentrated, requires larger volumes, and acts more slowly. Vitamin K helps restore factor production over hours to days but doesn’t reverse the current anticoagulant effect right away.
