7. Question : Of the answers below, which would be included in defining a positive Exercise Echocardiogram?
... [Show More] Student Answer: Death two days after test
Regional hypokensis of ventricular muscles walls
Induced decrease in regional wall motion (Induced decrease in regional wall motion would be included in defining a positive exercise echocardiogram. Wall thickening would not traditionally occur in a positive test and hyperkinesis, not hypokinesis, generally occurs in a positive test.)
Increase in wall thickening

Question 20. Question : Specifically, when is an ETT considered to be negative?
Student Answer: Patient has ST-segmental changes with down sloping of greater than 1 mm at 50% of age-predicted maximum heart rate
Patient exercises to 20% maximum age-predicted heart rate without induced ischemia
Patient exercises to 85% of age predicted maximum heart rate without evidence of induced ischemia (An ETT is considered to be negative when the patient exercises to 85% of age predicted maximum heart rate without evidence of induced ischemia. )
Patient exercises until tired without evidence of induced ischemia

Question 23. Question : Your patient has a maximum age-predicted heart rate of 180. During the exercise, he reaches a heart rate of 140 and then states he can no longer exercise. You see no evidence of ischemia on the ECG. This would be diagnostic for what condition?
Student Answer: Diagnostic of laziness
Has no diagnostic value to rule out CAD (This scenario has no diagnostic value to rule out CAD.)
Diagnostic for impending Myocardial Infarction
Predictive of no CAD

Question 27. Question : Your preceptor decides to add Doppler Flow studies to the echocardiogram exercise test for a patient with a recent history of a holistic murmur best auscultated at the left steral boarder. The patient has no history of cardiac surgeries. He asks you what might be the main advantages of adding Doppler Flow for this particular patient. You know from your readings that there are several reasons to add Doppler Flow and below are listed more than one correct reason. Your best response for this specific case, however, would be that Doppler Flow studies would be of what additive value during the echocardiogram study?
Student Answer: Detect and evaluate blood shunting from a septal defect (Your best response for this specific case, however, would be that Doppler Flow studies would detect and evaluate blood shunting from a septal defect.)
Gives better screen shots of wall abnormalities
Provides assessment of prosthetic valve function
No advantage is seen for this patient

Question 30. Question : The sensitivity of a routine ETT is effort dependent. What physiological changes occur during effort in the routine ETT?
Student Answer: Rapid heart rates and coronary artery narrowing
Decreased heart rate and increased systolic blood pressure
Decrease in coronary blood flow
Increased coronary flow and increased systolic blood pressure (The physiological changes that occur during effort in the routine ETT are increased coronary flow and increased systolic blood pressure.)

Question 34. Question : After completion of the exercise stress test, you would measure the ST-segment depression after the J point of the QRS. The J point is located where in relation to the QRS?
Student Answer: Immediately after the P wave
After the H point
Junction between P and R
Junction between QRS and ST segment (The J point is located at the junction between QRS and ST-segment.) [Show Less]
