Answer to Question 1

D
Feedback:
Maximum heart rate is calculated by subtracting a person's age from 220 . Thus, a 20-year-old's maximum heart rate is 200 beats per minute (bpm), whereas a 50-year-old client's maximum heart rate is 170 bpm. The target heart rate is 60 to 90 of the maximum heart rate. Beginners should not exceed 60, intermediates can exercise at 70 to 75, and competitive athletes can tolerate 80 to 90 of their maximum heart rate.

Answer to Question 2

D
Feedback:
The most important arrangement that a nurse should make during a step test is to ask for the assistance of personnel certified in cardiopulmonary resuscitation and the use of an automatic cardiac defibrillator if there is an adverse cardiac event. The step test is used with caution; hence, test time is shortened if the client develops discomfort. The examiner uses a metronome and a stopwatch to keep track of the rate and the time, but this is not the most important arrangement. The height of the step test machine platform is prescribed as per the client.
