perform the steps of the Allen test? and unclench the hand until it blanches. The nurse
1. Compress the radial and ulnar would then release one of the arteries and observe
arteries simultaneously. for immediate flushing on that side of the hand.
2. Ask the patient to clench and
unclench the hand.
3.Observe for blanching.
4.Remove pressure from the ulnar
artery.
5. Observe for immediate flushing of
the 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 the
which cardiovascular action? aortic valve.
Start of blood flow into the
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 falsely high
an intraarterial blood pressure systolic reading, when compared to the patient's
waveform is underdamped? Select cuff blood pressure.
all that apply. One, some, or all
responses may be correct. Narrow upward systolic peak
Falsely high systolic reading Underdamping causes narrowing of the upward
Increased dicrotic notch systolic peak.
Narrow upward systolic peak
Prolonged diastolic complex
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
, Question 2 of 4 It is important to prevent air embolisms and
In which order would the nurse bleeding while removing the central venous
perform the steps to remove a catheter. The nurse would place the patient flat and
central venous catheter? ask the patient to take a deep breath during
Correct Answer removal to prevent an air embolism from occurring.
Exactly!
Place the patient in a supine position.
Ask the patient to take a deep breath
and hold it.
Remove the central venous catheter
in a slow, steady motion.
Apply an occlusive dressing to the
site.
Question 3 of 4
Match the element of the central
venous pressure waveform to the
corresponding cardiac event.
Correct Answer
Exactly!
atrial relaxation
x descent
bulging of closed tricuspid valve
c wave
atrial filling
v wave
beginning of ventricular filling
y descent
