ARDMS Echo RDCS board registry practice test questions

Which is the following is the typical treatment for advanced pericarditis? a. thoracentesis b. stent placement c. heart transplant d. pericardectomy - Answer- d When recording flow velocity on the LVOT, the: a. PW Doppler cursor should be placed distal to the aortic valve closure b. CW doppler should be placed parallel to the aortic valve closure c. CW doppler should be placed perpendicular to the aortic valve closure d. PW Doppler cursor should be placed proximal to the aortic valve closure - Answer- d The ultrasound system relies on the ____________________ for accurate recording of motion clips on an echo a. R wave and T wave on the EKG b. system timer to be set at 5 seconds c. QRS on the EKG d. system timer to be set at 3 seconds - Answer- a Which of the following describes how to differentiate a ruptured chordae attached to a flail anterior mitral leaflet from a vegetation attached to the anterior mitral leaflet? a. Flail leaflets usually cause regurgitation and vegetations normally cause stenosis. b. Mitral vegetations normally form on the atrial side of the valve and the ruptured chordae related to a flail leaflet will be identified on the ventricular side of the valve. c. Vegetations are much more hypoechoic than the chordae tendinae. d. A flail mitral leaflet demonstrates a distinct appearance on m-mode that is easily differentiated from the m-mode appearance of vegetation on the valve. - Answer- b Which of the following decreases as aortic stenosis increases in severity? A: time velocity interval B: mean pressure gradient C: peak pressure gradient D: valve area - Answer- d
