A client who just received a diagnosis of a terminal illness begins to meticulously plan a lavish, expensive world trip, stating, "I've always wanted to see the world, and now I have the perfect excuse!" This behavior most likely represents which defense mechanism?
✓ Correct Answer: Option C
Denial is a defense mechanism where an individual refuses to accept or acknowledge a painful reality or fact. The client is avoiding the emotional impact of the terminal diagnosis by focusing on an unrealistic future plan.
