The antidote for unfractionated heparin (UFH) is:

  1. Idarucizumab

  2. Protamine sulfate

  3. Vitamin K

  4. Andexanet alfa

The correct answer is: Protamine sulfate

The antidote for unfractionated heparin (UFH) is protamine sulfate. This is because protamine sulfate works by binding to heparin to form a stable salt, neutralizing the anticoagulant effects of heparin. Idarucizumab is the specific antidote for dabigatran (a direct thrombin inhibitor), vitamin K is the antidote for warfarin (a vitamin K antagonist), and andexanet alfa is the antidote for factor Xa inhibitors (such as apixaban and rivaroxaban).
