D. Continuous submaximal cycle ergometer test.
What is the best test to help determine ejection fraction at rest and during exercise?
A. Angiography.
B. Thallium stress test.
C. Single-proton emission computer tomography.

The most accurate screening method for signs and symptoms of CAD is a
A. Maximal exercise test with a 12-lead ECG.
B. Submaximal exercise test with a 12-lead ECG.
C. Discontinuous protocol, stopping at 85% of maximal heart rate.

A client with a functional capacity of 7 MET, an ejection fraction of 37%, and an ST - segment depression of 1 mm below baseline on exertion
A. Should not exercise until his or her ejection fraction is >50%.
B. Is considered to be at low risk.

B. Belt length x resistance x revolutions pedaled per minute.
C. Resistance x distance flywheel traveled per revolution x revolutions per minute.
D. Resistance x distance flywheel traveled per revolution.
Adults age physiologically at individual rates. Therefore, adults of any specified age will vary widely in their physiologic responses to exercise testing. Special consideration should be given to older adults when giving a fitness test, because
A. Age is often accompanied by de conditioning and disease.
B. Age predisposes older adults to clinical depression and neurologic diseases.
C. Older adults cannot be physically stressed beyond 75% of age-adjusted maximum.
D. Older adults are not as motivated to exercise as those who are younger.
The definition of cardiorespiratory fitness is
A. The maximal force that a muscle or muscle group can generate in a single effort.
B. The coordinated capacity of the heart, blood vessels, respiratory system, and tissue metabolic systems to take in, deliver, and use oxygen.
C. The ability to sustain a held maximal force or to continue repeated sub maximal contractions.
D. The functional ROM about a joint.
Hydrodensitometry (hydrostatic weighing, underwater weighing) has several sources of error. Which of the following is NOT a common source of error when using this technique to determine body composition?
A. Measurement of the vital capacity of the lungs.
B. Interindividual variability in the amount of air in the gastrointestinal tract.
C. Interindividual variability in the density of the individual lean tissue compartment.
D. Measurement of the residual volume.
Which of the following criteria would NOT classify a client as having "increased risk"?
A. Signs and/or symptoms of cardiopulmonary disease.
B. Signs and/or symptoms of metabolic disease.
C. Two or more major risk factors for CAD.
D. Male older than 40 years with a history of clinical depression.
