Rationale: An exercise electrocardiography (ECG) test is used to evaluate the heart's response to physical stress. During the test, the heart's electrical activity is monitored while the client exercises, helping to identify any areas of ischemia or abnormal rhythms. This test helps healthcare providers assess the heart's function and detect any potential issues related to angina or other cardiac conditions.

Choices B, C, and D are incorrect as they convey misconceptions about disease management for CAD.

Correct Answer: B

Rationale: The correct answer is B. Taking frequent walks and avoiding prolonged bed rest are essential measures to promote circulation and reduce the risk of thrombophlebitis. Physical activity helps prevent blood from pooling and clotting in the veins, thus decreasing the likelihood of thrombophlebitis development.
