b. Myocardium.
c. Endocardium.
d. Pleural space.
Ans>>Pericardium.
2. The direction of blood flow through the heart is best described by
which of these?
a. Vena cava - right atrium - right ventricle - lungs - pulmonary artery
- left atrium - left ventricle
b. Right atrium - right ventricle - pulmonary artery - lungs - pulmonary
vein - left atrium - left ventricle

atrium - left ventricle - vena cava
d. Right atrium - right ventricle - pulmonary vein - lungs - pulmonary
,artery - left atrium - left ventricle
Ans>>Right atrium - right ventricle - pulmonary artery - lungs
- pulmonary vein - left atrium - left ventricle
3. The nurse is reviewing the anatomy and physiologic functioning
of the heart. Which statement best describes what is meant by atrial
kick?
a. The atria contract during systole and attempt to push against closed
valves.
b. Contraction of the atria at the beginning of diastole can be felt as a
palpita- tion.
c... Atrial kick is the pressure exerted against the atria as the
ventricles contract during systole.
d. The atria contract toward the end of diastole and push the remaining
blood into the ventricles.
Ans>>The atria contract toward the end of diastole and push the
remaining blood into the ventricles.
, 4. When listening to heart sounds, the nurse knows the valve closures that
can be heard best at the base of the heart are:

b. Tricuspid and aortic.
c. Aortic and pulmonic.
d. Mitral and pulmonic.
Ans>>Aortic and pulmonic.
5. Which of these statements describes the closure of the valves in a
normal cardiac cycle?
a. The aortic valve closes slightly before the tricuspid valve.
b. The pulmonic valve closes slightly before the aortic valve.
c. The tricuspid valve closes slightly later than the mitral valve.
d. Both the tricuspid and pulmonic valves close at the same time.
Ans>>The tricuspid valve closes slightly later than the mitral valve.
