A community health nurse is working with a group of homeless veterans who have posttraumatic stress disorder. Which of the following interventions should the nurse implement?

The correct answer is D: Teach the clients to practice deep breathing exercises. This intervention is appropriate because deep breathing exercises are a proven technique to help manage anxiety and stress, common symptoms of posttraumatic stress disorder. By teaching the veterans this skill, the nurse can empower them to cope with their symptoms effectively. Providing coffee and snacks (A) may be comforting but does not address the core issue. Avoiding discussing traumatic events (B) can hinder the therapeutic process. Changing meeting sites frequently (C) may disrupt the sense of safety and trust.
