the patient's heart rate exceeds 150 bpm?
a. both the QRS complex and the T wave increase in amplitude
b. both the QRS complex and the T wave decrease in amplitude
c. the QRS complex increases and the T wave decreases in amplitude
d. the QRS complex decreases and the T wave increases in amplitude - ANSWER
a. both the QRS complex and the T wave increase in amplitude
2. In stage three of the Bruce protocol the treadmill is set at:
a. 2.4 mph and a 12% grade
b. 2.4 mph and a 14% grade
c. 3.4 mph and a 12% grade
d. 3.4 mph and a 14% grade - ANSWER d. 3.4 mph and a 14% grade
3. With exercise, what two factors increase and lead to an increase in cardiac
output? - ANSWER heart rate and stroke volume
4. Which of the following methods for stress testing would provide the most
predictable work load?
a. steps
, b. cold pressor
c. pharmacologic
d. bicycle ergometer - ANSWER d. bicycle ergometer
5. Blood pressure from what artery
is normally monitored during an exercise stress
test?
a. radial
b. femoral
c. brachial
d. popliteal - ANSWER c. brachial
6. Sensitivity of a stress test - ANSWER the ability of a positive exercise stress
test to correctly identify patients with documented coronary artery disease (CAD)
- measures the proportion of true positives
7. Specificity of a stress test - ANSWER refers to the ability of the test to
accurately identify individuals who do not have the condition being tested for
- measures the proportion of true negatives
8. A true positive stress test - ANSWER the stress test is positive (indicating
coronary artery disease) and the angiogram is also positive confirming CAD
9. A false positive stress test - ANSWER stress test is positive for CAD, but the
angiogram is negative, revealing normal coronary arteries
