b.

c.
mediastinum.
d.
myocardium.
ANS: D
The myocardium is the specialized muscle layer that allows the heart to contract.
• The nurse clarifies that the master pacemaker of the heart is the:
a.
left ventricle.

a.
hepatitis A.
b.
indigestion.
c.
urinary infection.
d.
menopausal complications.
ANS: B
Indigestion, gallbladder attack, anxiety attack, and depression are frequent misdiagnoses for
women having an MI.
• The nurse identifies the LUBB sound of the LUBB/DUBB of the cardiac
cycle as the sound of the:
a.
AV valves closing.
b.
closure of the semilunar valves.
c.
contraction of the papillary muscles.
d.
contraction of the ventricles.
ANS: A
The LUBB is the first sound of a low pitch heard when the AV valves close.
