Review Lewis's Medical Surgical Nursing in Canada, 5th Edition - Nursing Assessment: Cardiovascular System related questions and content

The nurse is monitoring a patient who is undergoing exercise (stress) testing on a treadmill. Which of the following assessment findings requires the most rapid action by the nurse?

  • A. Patient complaint of feeling tired
  • B. Pulse change from 80 to 96 beats/minute
  • C. BP increase from 134/68 to 150/80 mm Hg
  • D. Electrocardiographic changes indicating coronary ischemia
Correct Answer: D

Rationale: ECG changes associated with coronary ischemia (such as T-wave inversions and ST segment depression) indicate that the myocardium is not getting adequate oxygen delivery and that the exercise test should be terminated immediately. Increases in BP and heart rate (HR) are normal responses to aerobic exercise. Tiredness also is normal as the intensity of exercise increases during the stress testing.
