An obese client with emphysema, who smokes at least a pack of cigarettes daily, is admitted after experiencing a sudden increase in dyspnea and activity intolerance. Oxygen therapy is initiated and it is determined that the client will be discharged with oxygen. Which information is most important for the nurse to emphasize in the discharge teaching plan?

Choice A rationale For a client with emphysema who will be discharged with oxygen, understanding the guidelines for oxygen use is crucial. Misuse of oxygen can lead to serious health complications, so it’s important that the client knows how to use it correctly. Choice B rationale While energy conservation approaches can be beneficial for a client with emphysema, they are not as crucial as understanding the guidelines for oxygen use. Choice C rationale While smoking cessation strategies are important for a client with emphysema, especially one who smokes heavily, they are not as crucial as understanding the guidelines for oxygen use. Choice D rationale While weight loss methods can be beneficial for an obese client, they are not as crucial as understanding the guidelines for oxygen use for a client with emphysema who will be discharged with oxygen.
