Question 1
What electrocardiogram (ECG) change would the healthcare professional assess for when a patient’s myocardial infarction extends through the myocardium from the endocardium to the epicardium?
◦ Prolonged QT interval
◦ ST elevation
◦ ST depression
◦ Prolonged PR interval
Question 2
How does angiotensin II increase the workload of the heart after a myocardial infarction (MI)?
◦ By increasing the peripheral vasoconstriction
◦ By causing dysrhythmias as a result of hyperkalemia
◦ By reducing the contractility of the myocardium
◦ By stimulating the sympathetic nervous system
