- rewrite: Problem 1 (Mental Health): The survivor victim is dealing with acute stress and symptoms of a post-traumatic stress disorder (PTSD) due to their traumatic experience during the January 2025 wildfire. Goal 1: To alleviate the client's overall level, frequency, and intensity of anxiety and PTSD symptoms so that daily functioning remains unimpaired. Objective 1: The client will learn and regularly use at least two anxieties management techniques to reduce anxiety symptoms to less than three episodes per week. Intervention 1: The therapist will provide psychoeducation about anxiety and PTSD, including their symptoms and triggers. The therapist will also teach and assist the client in adopting relaxation techniques, such as deep breathing exercises and progressive muscle relaxation, to better manage anxiety and lessen PTSD symptoms.arrow_forwardO Macmillan Learning You have 0.100 M solutions of acetic acid (pKa = 4.76) and sodium acetate.
