pulmonic stenosis
-pulmonary hypertension (new)
-PE (new)

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

,RCIS 2024-2025 QUESTIONS WITH CORRECT
ANSWERS

How much oxygenation do RBCs have the ability to release? - CORRECT ANSWER
30%
What valve is open at LVEDP? - CORRECT ANSWER Mitral valve
Normal wedge pressure - CORRECT ANSWER 7-12 (8)
Normal LA pressure - CORRECT ANSWER 7-12
Normal LV pressure - CORRECT ANSWER 120/(7-12)
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

-Tricuspid regurgitation
-Large RV infarct
How would a high pressure in the RA AFFECT SVC/IVC? - CORRECT ANSWER
Central venous pressure is elevated

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.
