hand.
,Question 2 of 4
Match the hemodynamic pressure
to
the corresponding explanation.
Correct Answer
Exactly!
Average perfusion pressure
created
during the cardiac cycle
=Mean arterial pressure
Pressure created by volume in the
right side of the heart
=Central venous pressure
Filling pressures in the left of the
heart when the mitral valve is
closed
=Left atrial pressure
Amount of blood pumped out by a
ventricle over 1 min
=Cardiac output
Question 3 of 4 Closure of the aortic valve
The dicrotic notch corresponds to The dicrotic notch occurs during closure of
which cardiovascular action? the
Start of blood flow into the aortic valve.
pulmonary vasculature
Opening of the pulmonic valve
Closure of the aortic valve
Contraction of the ventricles
,Question 4 of 4 Falsely high systolic reading
Which changes would indicate that Underdamping of the signal causes a
an intraarterial blood pressure falsely high
waveform is underdamped? Select systolic reading, when compared to the
all that apply. One, some, or all patient's
responses may be correct. cuff blood pressure.
Falsely high systolic reading Narrow upward systolic peak
Increased dicrotic notch Underdamping causes narrowing of the
Narrow upward systolic peak upward
Prolonged diastolic complex systolic peak.
Falsely low diastolic reading
Question 1 of 4
Match the central venous catheter
site to the corresponding
advantages.
Easiest to cannulize; small risk of
pneumothorax
Internal jugular
Lowest infection rate; least patient
discomfort from the catheter
Subclavian
No curves in insertion route; high
blood flow rate
Femoral

breath occurring.
and hold it.
Remove the central venous
catheter
in a slow, steady motion.
Apply an occlusive dressing to the
site.
Question 3 of 4
