Final answer:
The 'Holiday Heart' syndrome is associated with heart dysrhythmias like atrial fibrillation due to binge drinking, and it can lead to serious health complications if not addressed.
Step-by-step explanation:
The best response by the nurse to explain what “Holiday Heart” syndrome refers to is option (c) “This is the association of heart dysrhythmias, especially atrial fibrillation, with binge drinking.” Holiday Heart syndrome is characterized by the occurrence of arrhythmias, such as atrial fibrillation, in the absence of other heart conditions, often triggered by acute alcohol ingestion. While atrial fibrillation is a serious arrhythmia, it might not pose an immediate threat to life as long as the ventricles continue to pump blood. However, binge drinking-associated arrhythmias can lead to more serious health complications, hence the importance of addressing and treating the underlying cause.
