B- Metoprolol 60 mg administration

C- Stress test

D- Tissue plasminogen activator

A- Aspirin 325 mg administration- In any suspected myocardial infarction — including posterior MI — the very first and most important immediate step is to give chewable aspirin (325 mg) to inhibit platelet aggregation and limit clot progression. Reperfusion therapy (like tPA) comes after initial stabilization. Beta-blockers (like metoprolol) are not the first step and may be harmful in some MI settings. A stress test is never done during an acute MI.
