What is the antidote for a heparin overdose?

Vitamin K
Aspirin
Protamine sulfate
Tranexamic acid

The correct answer is: Protamine sulfate

Heparin is an anticoagulant medication, meaning it helps to prevent blood clots. However, too much heparin can lead to excessive bleeding and potentially be life-threatening. In this scenario, the antidote for a heparin overdose would be protamine sulfate, as it works to reverse the effects of heparin. Vitamin K, aspirin, and tranexamic acid do not have any effect on heparin overdose and are not recommended as antidotes for this type of situation. Therefore, option C is the best choice.
