b. Intermittent, multifocal premature ventricular contractions
c. Rapid resolution of ST elevation
d. Rapid rise in creatine kinase MB fraction

Question 2

Answer to Question 1

B, C, D
A reliable indicator of reperfusion is the appearance of various reperfusion dysrhythmias such as premature ventricular contractions, bradycardia, heart block, and ventricular tachycardia. Rapid resolution of the previously elevated ST segment should occur. The serum concentration of creatine kinase rises rapidly and markedly, a phenomenon termed washout.

Answer to Question 2

D
Ischemic stroke results from interruption of blood flow to the brain and accounts for 80 to 85 of all strokes. The interruption can be the result of a thrombotic or embolic event. Thrombosis can form in large vessels (large-vessel thrombotic strokes) or small vessels (small-vessel thrombotic strokes). Embolic sources include the heart (cardioembolic strokes) and atherosclerotic plaques in larger vessels (atheroembolic strokes). In 30 of the cases, the underlying cause of the stroke is unknown (cryptogenic strokes). Strokes are classified as ischemic and hemorrhagic. Hemorrhagic strokes can be further categorized as subarachnoid hemorrhages and intracerebral hemorrhages.
