MOCK TEST #2 CCI RCS EXAM
QUESTIONS AND ANSWERS (VERIFIED
AND UPDATED)
More than five big boxes apart - ANS Sinus tachycardia is defined as a heart rate more than
100 bpm how do the R waves appear on the ECG
Ventricular tachycardia - ANS The patient has an ECG with five premature ventricular
contraction's in succession what is this called
Tricuspid stenosis - ANS During diastole the right atrial pressure is much higher than the right
ventricular pressure what does this indicate
None of the above - it's normal - ANS During systole the left atrial pressure is much more
lower than the left ventricular pressure what does this indicate
False - ANS Two or false the size of a color flow jet is always related to the volume of blood
creating the jet
75% - ANS What is the normal O2 saturation of blood in the pulmonary artery
5MM HG - ANS What is a typical value for mean right atrial pressure

,Grade 5 of 6 - ANS A thrill is most like associated with which of the following murmurs
2 of 6 - ANS Which of the following grades represents a murmur that is most faint
Pulmonic insufficiency - ANS Which of the following flow patterns is most likely to be the
longest
False - ANS True or false the hemodynamic evaluation of MR is performed during diastole
False - ANS True or false the hemodynamic evaluation of aortic stenosis is performed during
diastole
True - ANS True or false the hemodynamic evaluation of tricuspid stenosis is performed
during diastole
True - ANS True or false hemodynamic evaluation of pulmonic regurgitation is performed
during diastole
Phase 0- depolarization rapid influx of sodium.
Phase 1- Repolarization potassium exits cell.
Phase 2- excitation contraction influx of calcium.
Phase 3-early repolarization sodium/potassium pump -sodium & potassium are pumped out.
Phase 4 - resting membrane potential- sodium & calcium remain outside of cell -- potassium
remain inside. - ANS Action potential
Mitral SV-Aortic SV / mitral SV x 100%
Aortic SV - Mitral SV / aoryic SV x 100% - ANS Mitral & Aortic Regurgitation fraction

, Decreases
Sympathetic - atria & ventricles
Parasympathetic- vagus nerve mostly atrial - ANS How does vagus nerve stimulation affect
the HR?
Always Regurgitant lesion is first. - ANS MR or AS which will be first?
First- closure of Mitral & tricuspid valves
Second - closure aortic A2 & pulmonic P2 valves
Third - early diastolic ventricular inflow
Fourth - atrial contraction - ANS Heart Sounds
4th - ANS Patient with A-fib what heart sound is missing?
Anterior interventricular sulcus - ANS Where does the LAD originate?
Power (watts)
---------------
Beam area (cm)^2 - ANS Intensity equation
(Amplitude) ^2 =dB - ANS Power equation
Wavelength mm= propagation speed / frequency
1.54/frequency =wavelength mm - ANS Wavelength equation
# cycles in a pulse x period = Pulse Duration (us) - ANS Pulse duration equation
