Step-by-step explanation:
The most beneficial thing you can teach a patient with congestive heart failure that might prevent hospitalization is to follow a healthy lifestyle, including regular exercise, a balanced diet, and smoking cessation. Regular exercise, such as 30 minutes of noncontinuous exercise each day, has been shown to lower the rate of heart attack. A healthy diet and quitting smoking also contribute to overall cardiovascular health. By adopting these lifestyle changes, the patient can improve their heart function and reduce the risk of hospitalization.
