Real Exam Questions And Correct Answers (100%
Correct Answers)
What is the pressure as blood enters the right atrium? - ANSWER>>
5mmHg
What organ system in the body acts on the blood in the vessels to make
a pressure of 5mmHg? - ANSWER>> Deep skeletal muscle pump system
What pressure is the blood under as it goes from the RA through the
tricuspid valve? - ANSWER>> 5mmHg
The bigger the diameter of the valve the __________ pressure is
needed to move blood across it. - ANSWER>> Less
The smaller the diameter of the valve the _________ pressure is
needed to move blood across it. - ANSWER>> more
What is the largest valve in the heart? - ANSWER>> tricuspid valve
What is the normal right ventricular systolic pressure? - ANSWER>>
25mmHg
How much smaller is the pulmonic valve than the tricuspid valve? -
ANSWER>> 5x smaller. It takes 5mmHg to get across the tricuspid valve
and 25mmHg to get across the pulmonic valve.
Which valve has a bigger diameter, the tricuspid or pulmonic valve? -
ANSWER>> Tricuspid

, Which valve requires more pressure to move across it, the tricuspid or
the pulmonic? - ANSWER>> pulmonic
Valve A requires 5mmHg to move blood and valve B requires 30mmHg.
Which valve has a smaller diameter? - ANSWER>> Valve B
What is the right ventricular diastolic pressure? - ANSWER>> 5mmHg
What is the RV EDP? - ANSWER>> 5mmHg
Why is the RV EDP not zero? - ANSWER>> Because some blood is not
ejected out. The heart is not a perfectly efficient pump.
What is a normal RV ejection fraction? - ANSWER>> 55-60%
What is EDP? - ANSWER>> End Diastolic Pressure. An efficient heart has
an ejection fraction of 55-60%, this leftover blood in the ventricle is
under a resting (diastolic) pressure.
What is a normal diastolic pressure in the pulmonary artery? -
ANSWER>> 7-12mmHg
What is the normal left atrial pressure? - ANSWER>> 7-12mmHg
What is the normal O2 concentration of a RBC leaving the lungs? -
ANSWER>> 98%
What is the normal O2 concentration of a RBC when it returns to the
RA? - ANSWER>> 70%
How much O2 is a RBC able to give up to the organs? - ANSWER>> 30%
of its O2

, True/False: If someone has a higher EDP there is less damage to the
heart. - ANSWER>> False, the higher the EDP the more damage. More
blood is being left and not pumped out.
What is a normal wedge pressure? - ANSWER>> 7-12mmHg
If the RBCs go through the lungs faster than 7-12mmHg what happens?
- ANSWER>> The RBCs have less time to get the O2 needed to fill them
up fully.
True or False: The higher the wedge pressure the faster the RBCs go
through the lungs and the less O2 they are able to acquire. - ANSWER>>
True.
COPD is elevated wedge pressure. True or False - ANSWER>> True. 30-
40mmHg is not unusual. RBCs move so fast that they come out of the
lungs with much less than 98% O2.
COPD O2 sats can be in the low to mid 80's. True or false - ANSWER>>
True.
Why is the wedge pressure indicative of the LA pressure? - ANSWER>>
Because there are no valves in between, just the lung system. Since no
valves the pressure in the LA should be the same. When the leaflets
open up on the mitral valve it is possible to see into the left ventricle.
When the mitral valve leaflets open up and the wedge catheter is able
to see into the LV what is the pressure that it sees? - ANSWER>> LV EDP
What is a normal LV EDP? - ANSWER>> 7-12mmHg
If the LV EDP goes up and the LA pressure goes up, what other pressure

would you expect to rise? - ANSWER>> The wedge pressure
, What would increase your right atrial pressure? - ANSWER>> tricuspid
stenosis
Where would you see a high RA pressure demonstrated on a patient? -
ANSWER>> Jugular vein distention
If a person has an RV MI will the RV systolic pressure be affected? -
ANSWER>> No matter how big the MI the systolic pressure will not
change. The RV EDP will increase as the RV is not as able to push the
blood out as effectively as before the MI.
Would an RV MI affect the diameter of the pulmonic valve or the
diameter of the pulmonic arteries? - ANSWER>> No
If a person has an RV MI would the RV EDP be affected? - ANSWER>>
Yes. If the muscle fibers are dead the heart's ability to squeeze is
impacted so more blood is left behind.
What would cause the LV systolic pressure to increase? - ANSWER>>
Aortic stenosis. (What would prevent a RBC from moving forward from
the RV?)
What would cause your LVEDP to increase but not increase your LV
systolic pressure? - ANSWER>> LV MI would increase the LV EDP
because the heart is less effective as a pump. As the LV is able to eject
less blood, the end diastolic pressure gets higher.
The systolic pressure does not need to increase because that is the
pressure to get the blood past the aortic valve.
As the EF (ejection fraction) goes down the EDP (end diastolic pressure)
