Answer to Question 1

Correct Answer: 1
The electrocardiogram reflects changes in conduction due to myocardial ischemia and necrosis. Classic ECG changes seen in acute myocardial infarction include ST-segment elevation. Loss of P waves occurs with atrial flutter and fibrillation. Bradycardia can be a normal or abnormal rhythm. Widening of the QRS complex occurs with bundle branch block.

Answer to Question 2

Correct Answer: 1
S3 and lung crackles are indications of heart failure. Manifestations of MI extension include chest pain and a return of positive laboratory finding (CK-MB and troponin). Renal failure is a late complication of heart failure and is not manifested with an S3 and crackles. Liver failure is not manifested with an S3 and crackles.
