Final answer:
The nurse should advise the client with chronic bronchitis to stop smoking, engage in regular physical activity, maintain good nutrition, and avoid respiratory irritants to promote better oxygenation.
Step-by-step explanation:
The nurse would identify the following lifestyle factors as affecting a client's oxygenation:
a. Smoking cessation: Smoking damages the lungs and airways, leading to decreased lung function and impaired oxygenation. Quitting smoking is crucial for improving lung health and oxygen levels.
b. Physical activity: Regular exercise helps improve cardiovascular health, strengthens respiratory muscles, and enhances overall lung function, thereby promoting better oxygenation.
c. Nutrition: Proper nutrition supports overall health, including lung function. Certain nutrients, such as antioxidants found in fruits and vegetables, can benefit lung health.
d. Avoiding respiratory irritants: Exposure to respiratory irritants such as air pollution, dust, chemicals, and allergens can worsen respiratory conditions and impair oxygenation. Avoiding these irritants can help maintain better lung function and oxygen levels.
Therefore, the correct answers affecting a client's oxygenation among the options provided are:
a. Smoking cessation
b. Physical activity
c. Nutrition
d. Avoiding respiratory irritants
