The nurse is working with a 60-year-old female client in a fitness setting. Which is the correct maximum desired heart rate target zone for both moderate- and vigorous-intensity workouts for this client?
1. 66-80, and 112-124.
2. 60-85, and 85-110.
3. 80-110, and 120-130.
4. 80-112, and 112-136.
Correct Answer: 4
derate intensity exercise should raise the heart rate 50-70%. Vigorous intensity exercise should raise the heart rate 70-85%. To calculate the minimum and maximum targets zones from each type of activity, you must first determine the maximum heart rate. This is done by subtracting the individual's age from 220. Therefore, 220 - 60 = 160. 160 × 0.5 (50%) = 80; 160 × 0.7 (70%) = 112. For vigorous activity, 160 × 0.7 = 112; 160 × 0.85 (85%) = 136. Therefore, 80-112, and 112-136 is the correct answer.
