Document Content and Description Below

The American Society of Echocardiography adopted the "leading edge" method of measurement because: A. People were turning up the gain too much. B. The nature of the interaction between ultrasound ... and anatomical interfaces makes this advisable. C. The advent of gray-scale M mode made this possible. D. It produces the most consistent and reproducible measurements. Correct Answer: D. In 1978 the American Society of Echocardiography recommended that all echo measurements be taken from the leading edge of each structure so that all laboratories would be using a consistent method. -It produces the most consistent and reproducible measurements. The term basilar area of the ventricle refers to the: A. Ventricular myocardium at the apex B. Mid segments of the ventricle C. Ventricular myocardium at the atrioventricular valves. D. None of the above. Correct Answer: C. The basilar area of the heart is at a level near the AV valves. -Ventricular myocardium at the atrioventricular valves. The infudibulum is related to the area of the right ventricle called the: A. inflow tract B. Outflow C. Apical area D. Subvalvular area Correct Answer: B. The infundibulum is a funnel shaped passage leading directly out the right ventricle. -Outflow tract The three primary branches of the aortic arch include all of the following EXCEPT the: A. Innominate artery B. Right subclavian artery C. Left common carotid artery D. Left subclavian artery Correct Answer: B. The right subclavian artery arises from the innominate (brachiocephalic trunk). -The right subclavian The term tunica intima refers to which of the following: A. The inner lining of the arterial wall B. The outer lining of the arterial wall C. Transverse arterial muscle fbers D. Longitudinal muscle fibers E. The middle layer of the arterial wall. Correct Answer: A. The inner lining of the arterial wall The term tunica adventitia refers to: A. The inner lining of the arterial wall. B. The outer lining of the arterial wall. C. Transverse arterial muscle fibers. D. The intimal wall. E. The middle layer of the arterial wall. Correct Answer: B. The three sections of the arterial wall are the intima, media, and the adventitia -The outer lining of the arterial wall. Dextracardia indicates: A. Enlargement of all cardiac chambers B. An abnormal conduction system C. Heart located in the right side of the chest D. Dual chambers of the right ventricle Correct Answer: C. Often people with dextracardia have all organs reversed. -Heart located in the right side of the chest You are asked to pay particular attention to the semilunar valves. These valves are the: A. Mitral and aortic valves B. Mitral and tricuspid valves C. Pulmonic and tricuspid valves D. Aortic and pulmonic valves Correct Answer: D. Semilunar refers to the crescent or half-moon shape of the aortic and pulmonic valves. -Aortic and pulmonic valves The great vessels of the heart are the: A. Inferior vena cava and superior vena cava B. Inferior vena cava and subclavian artery C. D. Aorta and pulmonary artery Correct Answer: D. The aortic and the pulmonary arteries are described as the great vessels. The aorta delivers oxygenated blood to the body, and pulmonary artery delivers unoxygenated blood to the lungs. -Aorta and pulmonary artery Name and label each point on the anterior mitral valve leaflet Correct Answer: -D, E, F, A, C Note that the B notch is seen only when there is interruption in the closure of the mitral valve. Name and label the three walls transected by the transducer at mid ventricular level: Correct Answer: A Anterior right ventricle wall, B Interventricular septum, C left ventricular posterior wall. Name and label all structures and chambers transected by the M-mode ultrasound beam directed thro [Show More]
