200 QUESTION NCLEX EXAM Question 1 See full question A client is scheduled to have a graded exercise test. The nurse explains to the client that the test will determine how: You Selected: well the body reacts to controlled exercise stress. Correct response: well the body reacts to controlled exercise stress. Explanation: Graded exercise testing is a diagnostic and prognostic tool used to determine the physiologic responses to controlled exercise stress. Information gained from a graded exercise test can achieve diagnostic, functional, and therapeutic objectives for the client. Graded exercise tests involve the use of a treadmill, stationary bicycle, or arm ergometry. The information obtained from this test is not used to set the incline on the treadmill, and measuring the distance walked and the duration of the walk are not the purpose of a graded exercise test. Remediation: Electrocardiography, exercise Question 2 See full question A nurse should include which discharge instruction for clients receiving tricyclic antidepressants?
