COMPLETE SOLUTIONS
the term basilar area of the ventricle refers to the: correct answer: ventricular myocardium at the apex the infundibulum is related to the area of the right ventricle called the: correct answer: outflow tract the three primary branches of the aortic arch include all of the following except: innominate artery right subclavian artery left common carotid artery left subclavian artery correct answer: right subclavian artery the term tunica adventia refers to : correct answer: the outer lining of the arterial wall dextracardia indicates: correct answer: heart located in the right side of the chest you are asked to pay particular attention to the semolinar valves. these valves are the : correct answer: aortic and pulmonic vavles the great vessels of the heart are the: correct answer: aorta and pulmonary artery
in Mmode, the structure used to pinpoint end systole for measurement is: correct answer: maximum anterior motion of the lv posterior wall the motion of the septum should be evaluated by mode at the: correct answer: midventricular level true/false. the coronary sinus returns blood to the left atrium correct answer: false true or false. the ostium of the coronary arteries may sometimes be visualized in a short-axis 2-d echo view at the level of the aov correct answer: true Since phases of the cardiac cycle are discussed in terms of systole and diastole of the ventricle, what phase would be occurring during atrial filling? correct answer: systole in the ECG cycle, late ventricular filling occurs after the: correct answer: Pwave if a patient presents with an early diastolic murmur you would concentrate interest on the: correct answer: AOV, PV which valve would you suspect to be abnormal if auscultation revealed an austin-flint murmur correct answer: Aov most authors consider the major components of the first heart sound to be: correct answer: closure of the atrioventricular valves
the term dyspnea refers to the condition of correct answer: difficulty in breathing if a patient awakens in the night with SOB, 1 to 2 hours after falling asleep, what disease might be suspected? correct answer: CHF true/ false anemia or cyanosis may be a manifestation of serious underlying heart disease correct answer: true palpation of arterial pulses is a method used to help determine the presence or absence of diagnostic physical signs for certain cardiac diseases. which of the following statements is/are correct? correct answer: -heart failure, obstruction of flow by valvular stenosis, and constrictive pericarditis can cause a diminished stroke volume -normal peripheral pulses arrive later than the carotid pulse
- pulsus alternans implies impaired ventricular function and is often present in massive pericardial effusion, particularly pericardial tamponade -ai and carotid atherosclerosis cause a large stroke volume, wide pulse pressure, and lowered peripheral resistance with resultant bounding hyperkinetic pulses true/false dextrocardia can be detected by chest X-ray, percussion, egg examination correct answer: true
if a patient awakens in the night with sob, 1 to 2hours after falling asleep, what disease might be suspected? correct answer: CHF anemia or cyanosis may be a manifestation of serious underlying heart disease correct answer: true which one of the following is most likely to cause a decrease in cardiac output? correct answer: decrease in LV stroke volume a decrease in LV contractility secondary to acute myocardial infarction will: correct answer: decrease CO by decreasing pressure if all other factors remain constant, you would expect a reduction in vessel diameter to correct answer: increase velocity which one of the following is most likely to cause turbulent flow of blood in the aorta? correct answer: an increase in CO from 5L/min to 20L/min which of the following are characteristics of turbulent flow? correct answer: it can be predicted by Reynolds number it is responsible for murmurs, bruits and thrills it occurs where there are abrupt variations in vessel diameter it is affected by velocity during an experiment, a laboratory animal suddenly develops 2:1 heart block, effectively reducing heart rate by one half. Which one of the following responses would account for
as the arterial pressure wave moves toward the periphery, all of the following occur except: correct answer: speed of propagation diminshes the insecure on the aortic pressure wave: correct answer: is inscribed just after the aov closes Starlings law of the heart can best be expressed by which one of the following? correct answer: within limits, an increase in venous return results in an increase in stroke volume which one of the following best describes the role of the heart as a pump correct answer: forcing blood from the venous to the arterial circulation, restoring energy necessary for the blood flow which ultrasound system control automatically calibrates for measurements? correct answer: depth T/f increasing system gain can reduce technical artifacts correct answer: false the purpose of the TGC circuit is: correct answer: to suppress near-field echoes to enhance far-field echoes to compensate for loss of ultrasound energy(attenuation) as the beam enters the body
which of the following are T/F regarding the side lobes seen in 2-d images: correct answer: they are generated from the edges of individual transducer
