A 28-year-old client is admitted to the psychiatric unit following a motor vehicle accident. The client reports experiencing recurrent flashbacks, intrusive thoughts, and hypervigilance. The nurse suspects the client is experiencing symptoms of PTSD. Which assessment finding further supports this suspicion?

A. Binge eating and weight gain are more commonly associated with eating disorders or other psychological conditions, not PTSD. B. Nightmares, difficulty concentrating, and irritability are key symptoms of PTSD, reflecting the psychological impact of trauma. These are consistent with the intrusive and arousal symptoms associated with PTSD. C. Purging is associated with eating disorders, not PTSD. D. Decreased energy and fatigue are common symptoms of depression, not specifically indicative of PTSD, although they can be seen in both conditions.
