The first heart sound is produced by the:
closure of the semilunar valves.
closure of the AV valves.
opening of the semilunar valves.
opening of the AV valves. - ,,answer,,closure of AV valves
,Which of the following guidelines may be used to identify which
heart sound is S1?
S1 is louder than S2 at the base of the heart.
S1 coincides with the A wave of the jugular venous pulse wave.
S1 coincides with the carotid artery pulse.
S1 coincides with the Q wave of the QRS electrocardiogram
complex. - ,,answer,,S1 coincides with the carotid artery pulse.
Which of the following cardiac alterations occurs during pregnancy?
An increase in cardiac output and blood pressure
An increase in cardiac volume and a decrease in blood pressure
An increased heart rate and increased blood pressure
An increased stroke volume with decreased cardiac output -
,,answer,,An increase in cardiac volume and a decrease in blood
pressure

assume when auscultating for extra heart sounds or murmurs?
Roll toward the left side
Roll toward the right side
Trendelenburg position
Recumbent position - ,,answer,,roll toward left side
The leaflets of the tricuspid and mitral valves are anchored by
__________________ to the _________________, which are embedded in the
ventricular floor.
endocardial ligaments; mediastinal muscles
atrioventricular tendons; pericardial bundles
chordae tendineae; papillary muscles
,pericardial cords; ventricular sheaths - ,,answer,,chordae tendineae;
papillary muscles
The ability of the heart to contract independently of any signals or
stimulation is due to:
depolarization.
automaticity.
conduction.
repolarization. - ,,answer,,automaticity
When auscultating the heart of a newborn within 24 hours after
birth, the examiner hears a continuous sound that mimics the sound
of a machine. This finding most likely indicates:
the presence of congenital heart disease.
a normal sound because of the thinner chest wall of the newborn.
an expected sound caused by nonclosure of the ductus arteriosus.
pathology only when accompanied by an increased heart rate. -
,,answer,,an expected sound caused by nonclosure of the ductus
arteriosus.
A bruit heard while auscultating the carotid artery of a 65-year-old
patient is caused by:
decreased velocity of blood flow through the carotid artery.
turbulent blood flow through the carotid artery.
rapid blood flow through the carotid artery.
increased viscosity of blood. - ,,answer,,turbulent blood flow
through the carotid artery.
he jugular venous pressure is an indirect reflection of the:
heart's efficiency as a pump.
, cardiac cycle.
conduction effectiveness.
synchronization of mechanical activity. - ,,answer,,heart's efficiency
as a pump.
he semilunar valves separate the:
atria from the ventricles.
right atria from the left atria.
ventricles from the arteries.
atria from the veins. - ,,answer,,ventricles from arteries
