The nurse is assessing a client's activity tolerance by having the client walk on a treadmill for 5 minutes. Which of the following indicates an abnormal response?
Correct answer
B
Rationale
A decrease in respiratory rate after exercise is abnormal, as physical activity typically increases respiratory demand to meet oxygen needs. A pulse increase of 20 bpm, a slight rise in diastolic blood pressure, and a near-return to resting pulse after 3 minutes are normal responses to moderate exercise.
