Aclient with a history of cocaine addiction is admitted to the coronary care unit for evaluation of substernal chest pain. the electrocardiogram (ecg) shows a 1-mm st-segment elevation in the anteroseptal leads and t-wave inversion in leads v3 to v5. which medication should the nurse prepare to administer?

The patient diagnosis should be ST-elevated myocard infarct(STEMI) which was mostly caused by a thrombus in the cardiac vessel reducing the supply of oxygen. In this case, there are a few kind of drug that might be needed.
Give the patient oxygen then nitrate given sublingually to dilate the cardiac vein so the oxygen to heart increased. Analgesic drug can be given to reduce the pain(up to morfin).
Optional drug:
An antiplatelet drug(aspirin/clopidogrel) can be given if there is no sign of active bleeding. Anticoagulant also an option but it has many things to be considered. If the blood pressure increased you can give anti-hypentensive drug. If the patient also has heart failure and have fluid overload, furosemide can also be administered.
