A patient with coronary artery disease asks how to reduce the workload of the heart during daily activities. Which instruction is most appropriate?
Correct answer: B. Plan activity with rest periods and avoid heavy exertion
- A. Stop prescribed medicines when symptoms improve
- B. Plan activity with rest periods and avoid heavy exertion
- C. Exercise vigorously immediately after large meals
- D. Use extra salt to maintain circulating volume
Explanation
Pacing activity with planned rest reduces myocardial oxygen demand and helps prevent exertional ischaemia. Prescribed medicines should continue as directed, heavy exertion after meals may increase demand, and excess salt can worsen fluid retention and blood pressure.
