ANSWERS
Pressure in the right atrium - CORRECT ANSWER 5
Biggest valve in the heart - CORRECT ANSWER Tricuspid valve
How many times smaller is pulmonic valve than tricuspid valve? - CORRECT ANSWER
5 times smaller
Normal RV pressure - CORRECT ANSWER 25
EDP - CORRECT ANSWER The blood left behind in ventricles at the end of diastole
What should RVEDP equal? - CORRECT ANSWER RA pressure (5mm)
What can cause RVEDP to increase? - CORRECT ANSWER -RV MI
-Chronic pulmonary stenosis
-Chronic pulmonary hypertension
What would cause RV systolic pressures to increase? - CORRECT ANSWER -
pulmonic stenosis
-pulmonary hypertension (new)
-PE (new)
-COPD
Blood can't cross to PA if pressure isn't the same or less
What happens if EDP goes up? - CORRECT ANSWER LV dysfunction which lowers EF
If the wedge is up what happens to SATs? - CORRECT ANSWER SATs go down

How is BP calculated? - CORRECT ANSWER CO x SVR
How is CO calculated? - CORRECT ANSWER HR x SV
What causes the RV systolic to be 25? - CORRECT ANSWER The RBCs need to get
across the pulmonic valve
What would increase RA pressure? - CORRECT ANSWER -Tricuspid stenosis
-Tricuspid regurgitation
-Large RV infarct
How would a high pressure in the RA AFFECT SVC/IVC? - CORRECT ANSWER
Central venous pressure is elevated
If RA pressure was increased, where would this be visible on the patient? - CORRECT
ANSWER Jugular vein distention
, RCIS 2024-2025 QUESTIONS WITH CORRECT
ANSWERS
In an RV MI what is the RV pressure? - CORRECT ANSWER 25/5 (normal); it stays
the same because the RV pressure doesn't affect the diameter of the pulmonic valve.
The muscle fibers that are left have to work harder, but are still doing the same amount
of work.
Does an RV MI affect RVEDP? - CORRECT ANSWER Yes, it would increase it.
What would cause LV systolic pressure to increase? - CORRECT ANSWER Aortic
stenosis
What would increase LVEDP not LV systolic pressure? - CORRECT ANSWER LV MI;
because muscle is dying and cannot pump out all the blood LVEDP goes up.
What happens to RV systolic pressure with pulmonary stenosis? - CORRECT ANSWER
It increases
What happens to RA pressure with tricuspid regurgitation? - CORRECT ANSWER It
increases
What happens to PA pressure with COPD? - CORRECT ANSWER It's higher
What happens to PA pressure with mitral stenosis? - CORRECT ANSWER It is higher
What happens to PA pressure with mitral regurgitation? - CORRECT ANSWER It is
higher
Could the PA systolic pressure ever be greater than RV systolic pressure? - CORRECT
ANSWER No, because the blood flows to either the same pressure or lower. If the
pressure was higher, the blood would never get there.
