In this concise NCLEX‑style review, the speaker explains the essential nursing knowledge for myocardial infarction (MI). The presentation begins with the pathophysiology—coronary artery occlusion that deprives heart muscle of blood—leading to classic symptoms such as chest pain, fatigue, shortness of breath, and radiating pain. It then outlines the priority assessments: cardiac and respiratory exams, monitoring intake/output, continuous ECG surveillance for ST‑segment changes, and the potential need for an angiogram. Key laboratory markers (troponin, CK, CK‑MB, myoglobin, LDH) are highlighted for diagnosis. Finally, the speaker lists core nursing interventions: frequent vital signs, IV site maintenance, ongoing assessments, and medication management including oxygen, aspirin, thrombolytics, and nitrates. The content serves as a rapid refresher for nursing students preparing for the NCLEX exam.
