A nurse is caring for a 9-year-old child who mimics shooting a gun with their hand whenever someone enters the room or tries to interact with them.

 This is an example of which manifestation of post-traumatic stress disorder? 

Choice A rationale
Derealization involves feeling detached or disconnected from one’s surroundings, not changing details of a traumatic event.
Choice B rationale
Hypervigilance involves being overly alert or watchful, especially to potential danger, not changing details of a traumatic event.
Choice C rationale
Dissociative amnesia can involve difficulty remembering important information about a traumatic event, which can lead to inconsistencies in the child’s recollections.
Choice D rationale
Depersonalization involves feeling detached or disconnected from oneself, not changing details of a traumatic event.

Choice A rationale
The adolescent’s experimentation with drugs could be a coping mechanism to deal with the trauma of the sexual assault and the subsequent posttraumatic stress disorder (PTSD).
Substance use, including drug use, is often a maladaptive coping strategy used by individuals

who have experienced trauma to numb their feelings, escape from their reality, or attempt to regain control. This must indeed be a difficult time for both the adolescent and the parent.
Choice B rationale
While experimentation is a part of normal adolescent behavior, it is not normal or healthy for an adolescent to use drugs, especially in response to a traumatic event such as a sexual assault. Drug use can lead to addiction, health problems, and further psychological distress. Therefore, it is something to be concerned about and addressed appropriately.
Choice C rationale
While it is important to understand and address the parent’s concerns, the focus should be on the adolescent’s needs. The adolescent is dealing with the aftermath of a sexual assault and a diagnosis of PTSD, and is using drugs. These are serious issues that need to be addressed with professional help. The question of which behavior to address first should be determined based on the adolescent’s immediate safety and well-being.
Choice D rationale
It is not helpful to label the adolescent’s behavior as misbehavior or to compare them to their siblings. Each child is unique and may react differently to stress and trauma. Instead of focusing on rules and comparisons, it would be more beneficial to provide support, understanding, and appropriate professional help.
