Sample NBME 15 Question and Explanation Breakdown Question Example _A 65-year-old man presents with chest pain radiating to his left arm, sweating, and shortness of breath. His ECG shows ST-segment elevation in leads II, III, and aVF. Which of the following is the most likely diagnosis?_ Correct Answer: Myocardial Infarction (Inferior Wall) Explanation: This question tests your ability to interpret ECG findings and associate them with clinical presentation. The ST-segment elevation in leads II, III, and aVF indicates an inferior wall myocardial infarction, typically due to occlusion of the right coronary artery. The symptoms of chest pain, radiation, diaphoresis, and shortness of breath support this diagnosis. Knowing the correlation between ECG leads and coronary artery territories is essential, and understanding the management—such as immediate reperfusion therapy—is reinforced in the explanation. 4 Distractors Analysis - Left bundle branch block: Would show widened QRS complexes, not isolated ST elevations. - Pericarditis: Usually presents with diffuse ST elevations and PR depressions, not localized to specific leads. - Aortic dissection: Typically presents with sudden chest/back pain, but ECG findings are variable. - Gastroesophageal reflux: Does not produce ECG changes or chest ECG findings. This explanation emphasizes pattern recognition, clinical reasoning, and differential diagnosis, which are critical for success on the exam.
