Final answer:
Additional teaching is required if a client with heart disease mistakenly believes they need to stop exercising if their pulse is below the target zone. The correct approach is to adjust exercise intensity, not necessarily to stop. Regular aerobic activity is beneficial for cardiovascular health, but overexertion should be avoided.
Step-by-step explanation:
The question pertains to the signs of overexertion and when additional teaching is required in the context of a client with heart disease who is learning about exercise. Additional teaching is needed if the client states: "I should stop exercising if my pulse is below my target zone." This statement suggests a misunderstanding because having a pulse below the target zone does not necessarily indicate a need to stop exercising; it may just require an adjustment in intensity. Warm-up exercises, waiting after eating, and medical attention for what feels like a racing heart are all appropriate guidelines. Regular aerobic exercise, according to the American Heart Association, should be performed for 20-30 minutes, 3-5 times a week to help maintain cardiovascular health. However, overexertion, such as exercising too intensely without proper rest, can lead to adverse effects, including heart rhythm abnormalities and injuries.
