Which statement describes the mechanism by which citrate anticoagulation inhibits clot formation?

Explanation:
Citrate works by binding calcium ions, which are essential cofactors for the coagulation cascade. Without free calcium, the steps that convert prothrombin to thrombin and accumulate other activated factors cannot proceed, so clot formation is halted. This binding is reversible, so when citrate is removed or calcium is added back, coagulation can resume. Citrate does not add calcium, does affect calcium (not potassium), and its primary action is on calcium, not potassium.
