Quiz: How much do you know about prehospital TXA?

Have you had the chance to utilize TXA in the field? Learn more about the practice and test your knowledge


Have you utilized tranexemic acid (TXA) in the prehospital setting? In EMS1 columnist Jonathan Lee's recent article, "Understanding TXA," he explains its role in the field and which patients could benefit, as well as which conditions specifically could be made worse by incorporating TXA. 

Read Lee's article, and then test your knowledge with a quiz. Be sure to add your score to the comments.
