Answer : A

The following results were obtained from a symptom-limited exercise (stress) test:

Which of the following is true regarding these data?

  • A. The patient is deconditioned.
  • B. The patient has a cardiac limitation to exercise.
  • C. The patient reached the anaerobic threshold.
  • D. The patient has a pulmonary limitation to exercise.

Answer : B

The following data are obtained for a 60-year-old male undergoing an exercise (stress) test on an ergometer:

A pulmonary function technologist should

  • A. Stop the test because the blood pressure response is abnormal.
  • B. Stop the test because the heart rate is too high after 10 minutes.
  • C. Stop the test because this is an abnormal VD/VT response.
  • D. Continue the test since this is a normal cardiopulmonary response.

Answer : A

  • D. An increase in VE of 10to15L/min/torrPCO2.

Answer : C
