Test Questions

Question 1

What drug do you expect to give to a patient with an anterior wall MI?

Answer 1

beta blockers because they decrease the work of the heart and increase the threshold for ventricular fibrillation; the beta blocker of choice is metoprolol

Question 2

What beta blocker should be avoided in patients with an anterior wall MI?

Answer 2

Propranolol because it is not a cardioselective beta blocker. It affects beta receptors in heart AND lung tissue. therefore, it is more likely to cause bronchoconstriction that a cardioselective beta blocker

Question 3

What heart blocks can be noted in an LAD occlusion?

Answer 3

The LAD supplies the bundle of HIS, which should result in a second-degree, Type II heart block

Question 4

What heart blocks can be noted in an RCA occlusion

Answer 4

The RCA supplies the SA and AV node.

Question 5

What is Dressler’s syndrome?

Answer 5

a type of pericarditis that occurs as a result of an immune response after an MI, surgery, or traumatic injury

Question 6

Complications of an RCA occlusion include

Answer 6

papillary muscle dysfunction or rupture of the mitral valve

Question 7

IABP balloon inflation

Answer 7

increases coronary artery perfusion; inflates at dicrotic notch of the arterial waveform, beginning of diastole

Question 8

IABP deflation

Answer 8

decreases afterload; deflates right before systole begins; determined by set trigger for deflation, R-wave of ECG or upstroke of arterial pressure wave

Question 9

What is a VSD?

Answer 9

Ventricular septal defect, which is most common with acute MI, may result in systolic murmur. It is heart at the left sternal border, 5th ICS
