1. The nurse is caring for a patient who is on a cardiac A
monitor. The nurse realizes that the sinus node is the
pacemaker of the heart because it is
a. the fastest pacemaker cell in the heart.
b. the only pacemaker cell in the heart.
c. the only cell that does not affect the cardiac cycle.
d. located in the left side of the heart.
2. One of the functions of the atrioventricular (AV) node B
is to
a. pace the heart if the ventricles fail.
b. slow the impulse arriving from the SA node.
c. send the impulse to the SA node.
d. allow for ventricular filling during systole.
3. The patient is admitted with a suspected acute my- A
ocardial infarction (AMI). In assessing the 12-lead elec-
trocardiogram (ECG) changes, which findings would
indicate to the nurse that the patient is in the process
of an evolving Q wave myocardial infarction (MI)?
a. ST-segment elevation on ECG and elevated CPK-MB
or troponin levels
b. Depressed ST-segment on ECG and elevated total
CPK
c. Depressed ST-segment on ECG and normal cardiac
enzymes
d. Q wave on ECG with normal enzymes and troponin
levels
4. The nurse is assessing a patient with left-sided heart C
failure. Which symptom would the nurse expect to
find?

a. Dependent edema
b. Distended neck veins
c. Dyspnea and crackles
d. Nausea and vomiting
5. A patient is admitted with an acute myocardial infarc- C
tion (AMI). The nurse knows that an angiotensin-con-
verting enzyme (ACE) inhibitor should be started with-
in 24 hours to reduce the incidence of which process?
a. Myocardial stunning
b. Hibernating myocardium
c. Myocardial remodeling
d. Tachycardia
6. A patient presents to the emergency department (ED) A
with chest pain that he has had for the past 2 hours.
The patient is nauseated and diaphoretic, with dusky
skin color. The electrocardiogram shows ST elevation
in leads II, III, and aVF. Which therapeutic intervention
would the nurse question?
a. Emergent pacemaker insertion
b. Emergent percutaneous coronary intervention
c. Emergent thrombolytic therapy
d. Immediate coronary artery bypass graft surgery
7. A patient is admitted with the diagnosis of unstable C
angina. The nurse knows that the physiological mech-
anism present is most likely which of the following?
a. Complete occlusion of a coronary artery
b. Fatty streak within the intima of a coronary artery
c. Partial occlusion of a coronary artery with a throm-
