NSG 5002 FINAL EXAM QUESTIONS AND ANSWERS VERIFIED 100% CORRECT | AGRADE What ECG changes can reduce the specificity of the ETT? Question 22 options: b) Exercise induced bundle branch blocks c) Paced rhythm and exercise induced bundle branch blocks d) Low voltage up sloping of the ST-segment Save Question 23 (2.75 points) Why would inability to exercise reduce the specificity of the routine ETT? Question 23 options: b) Produces QRS changes that cannot be interpreted c) Causes ST-segment changes and P-wave abnormalities d) Will not produce any changes in ECG Save a) Produces persistent ST-segmental changes and T-wave abnormalities Question 24 (2.75 points) The sensitivity of a routine ETT is effort dependent. What physiological changes occur during effort in the routine ETT? Question 24 options: a) Decrease in coronary blood flow b) Decreased heart rate and increased systolic blood pressure c) Rapid heart rates and coronary artery narrowing Save Question 25 (2.75 points) Specifically, when is an ETT considered to be negative? Question 25 options: b) Patient exercises until tired without evidence of induced ischemia c) Patient has ST-segmental changes with down sloping of greater than 1 mm at 50% of age-predicted maximum heart rate d) Patient exercises to 20% maximum age-predicted heart rate without induced ischemia Save Question 26 (2.75 points) d) Increased coronary flow and increased systolic blood pressure Your mentor says that you should be prepared to know how to determine the maximum heart rate for your patient during the ETT. How is the age-predicted maximum heart rate during an ETT determined? Question 26 options: Save Question 27 (2.75 points) 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?

c) Patient has ST-segmental changes with down sloping of greater than 1 mm at 50% of age-predicted maximu
heart rate

Save

Question 26 (2.75 points)

,Your mentor says that you should be prepared to know how to determine the maximum heart rate for your
patient during the ETT. How is the age-predicted maximum heart rate during an ETT determined?
