Which client is most at risk for exacerbation of heart failure?

A client experiencing atrial fibrillation and who has not taken amiodarone for one month is at an increased risk for exacerbation of heart failure. Atrial fibrillation can lead to inefficient pumping of the heart due to irregular and often rapid heart rhythms. This situation can significantly increase the workload on the heart and may result in fluid accumulation, worsening heart failure symptoms such as shortness of breath, edema, and fatigue. The absence of amiodarone, which is an antiarrhythmic medication that helps manage heart rhythm and reduce the risk of complications, further compounds this risk. Without proper medication management, the client’s condition may deteriorate, leading to an exacerbation of heart failure.

In contrast, the other options reflect behaviors and management strategies that typically support heart health and mitigate the risk of heart failure exacerbations. Regular exercise can enhance cardiovascular fitness, maintaining a low-salt diet can manage fluid retention, and keeping up with healthcare appointments can ensure ongoing assessment and management of heart failure. These practices are generally associated with better outcomes in individuals with heart conditions.
