Question: 1 / 910

Which of the following is NOT a mechanism of action for anticoagulants?

Inhibiting vitamin K

Inhibiting ADP receptors

Increasing clotting factors

Anticoagulants are primarily designed to prevent blood clot formation, and their mechanisms of action typically involve inhibiting factors involved in the coagulation cascade or preventing platelet activation and aggregation. Increasing clotting factors would counteract the purpose of anticoagulants, as it would promote clot formation rather than inhibit it.

In contrast, other mechanisms associated with anticoagulants include inhibiting vitamin K to prevent the synthesis of vitamin K-dependent clotting factors, inhibiting ADP receptors to prevent platelet activation, and inhibiting platelet aggregation to reduce the overall ability of platelets to form clots. Thus, the response of increasing clotting factors is not consistent with the therapeutic goal of anticoagulants, making it the correct answer as the mechanism that does not align with anticoagulant action.
