The client with PTSD needs encouragement to examine and understand the meaning of the traumatic event and consequent losses. Otherwise, symptoms may worsen and the client may become depressed or engage in self-destructive behavior such as substance abuse. The client must explore the meaning of the event and wonâ€™t heal without this, no matter how much time passes. Behavioral techniques, such as relaxation therapy, may help decrease the clientâ€™s anxiety and induce sleep. The physician may prescribe antianxiety agents or antidepressants cautiously to avoid dependence; sleep medication is rarely appropriate. A special diet isnâ€™t indicated unless the client also has an eating disorder or a nutritional problem.
