Which tertiary level intervention could be included in the care of an elderly client with heart failure?

The correct answer is reinforcing past teachings on how to read food labels, as it focuses on an essential aspect of managing heart failure: dietary modifications. Clients with heart failure often require a careful diet low in sodium and other heart-unfriendly components, and being able to read food labels helps them make informed choices that can significantly influence their condition.

Tertiary interventions aim to manage and improve outcomes for individuals with an established disease and reduce complications. In this context, emphasizing the importance of understanding nutrition directly supports the client’s ability to manage their heart failure effectively. It empowers them and encourages proactive participation in their health care by avoiding foods that may exacerbate their condition.

Monitoring vital signs, scheduling routine cardiac tests, and encouraging daily exercise regimes are also important components of heart failure management but are more aligned with primary and secondary interventions. Monitoring can help track changes in the patient's condition, and exercise may be recommended depending on the individual’s health status, but reinforcing dietary knowledge specifically addresses the self-management aspect that is crucial for someone living with heart failure at the tertiary care level. Therefore, the emphasis on food label literacy fits well into the context of tertiary level care for an elderly heart failure client.
