CCI - RCS EXAM QUESTIONS AND
CORRECT ANSWERS
the resistance against which the ventricle contracts is known as the ANSW✅✅afterload
after the administration of IV contrast what should the patient be instructed to do ANSW✅✅drink
plenty of fluids
which 2-dimensional echocardiographic views could be used to planimeter the mitral valve area
ANSW✅✅parasternal short axis
which are measures of LV systolic function (choose 2) ANSW✅✅1. Ejection fraction
2. Global Longitudinal strain (GLS)
Which patient positions are best when acquiring images from the subcostal window (choose 2
positions) ANSW✅✅1. supine
2. knees slightly bent
what should be documented on every echo report (choose 3) ANSW✅✅1. size of the aorta
2. ventricular size and function
3. comment if a major structure was not well visualized
*what will decrease the frame rate while utilizing color doppler (2 reponses) ANSW✅✅1. increase
ROI sector width
2. increase image depth
*which of the following is a bileaflet tilting disc mechanical valve ANSW✅✅St. Jude
What is the equation for determining cardiac output from ventricular volume ANSW✅✅(LVEDV -
LVESV) x HR
, what statement could be made about a prosthetic aortic valve with the following measurements
(peak velocity = 2.7 m/sec ; doppler velocity index = 0.35 ; acceleration time = 70 ms)
ANSW✅✅Possibly stenotic
What finding would warrant immediately notifying the interpreting physician immediately
ANSW✅✅clot in transit
What artifact is most often associated with a St. Jude mechanical valve? ANSW✅✅Reverberation
what is the condition where bacteria in the bloodstream colonize on the valves of the heart
ANSW✅✅infective endocarditis
during an ultrasound examination adjustment of the time-gain controls compensates for
ANSW✅✅
The maximum mechanical index setting used for ultrasound enhancement agent (contrast) should
NOT exceed ANSW✅✅1.9
Which echo paramaters would be best used to assess the left atrial appendage for a clot during a
TEE (choose 2) ANSW✅✅1. PW doppler
2. Ultrasound enhancing agent
Under what circumstances would it be appropriate to have your patient perform a valsalva
maneuver ANSW✅✅Valsalva is used to decrease preload and provoke left ventricular outflow
tract (LVOT) gradient in dynamic LVOT obstruction. In addition, a decrease in E/A ratio in mitral
inflow >50 % with Valsalva correlates with increased LV filling pressure and diastolic dysfunction.
Valsalva also momentarily increases RA pressure and helps to unmask a patent foramen ovale with
the use of saline contrast.
**what coronary artery is most likely to supply blood to the lateral wall of the left ventricle
ANSW✅✅circumflex artery
**What is the severity of a TR waveform with a dense, triangular CW jet and a vena contracta
measuring of 0.9 cm ANSW✅✅Severe
TR vena contracta (VC) of >0.7 cm identifies severe TR
