The nurse is caring for a client who is having an acute myocardial infarction (MI) in the emergency department. What drug will the nurse administer before admitting the client to a unit in the hospital?

A. Anagrelide: Anagrelide is primarily used to treat conditions like thrombocythemia and is not used for the immediate treatment of myocardial infarction. It is not an appropriate drug for this scenario. B. Clopidogrel: Clopidogrel is an antiplatelet agent often used in the management of myocardial infarction, but it is typically used as an immediate treatment in the acute phase of an MI. It helps prevent further clot formation after initial therapy. C. Ticlopidine: Ticlopidine is a platelet aggregation inhibitor, but it is not a first-line therapy in acute myocardial infarction. It is not commonly used in emergency settings like tenecteplase. D. Tenecteplase: Tenecteplase is a fibrinolytic (thrombolytic) agent used in the acute setting of myocardial infarction to break down the clot blocking blood flow to the heart. It is administered early to dissolve the thrombus and restore circulation early.
