Core Nursing Explanation
This question tests the ability to identify the cardinal symptoms of
Post-Traumatic Stress Disorder (PTSD) during a psychiatric nursing assessment. PTSD is a trauma- and stressor-related disorder characterized by a specific cluster of symptoms that develop after exposure to a traumatic event.
Key Concept Analysis
The core of PTSD is organized into four symptom clusters according to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition):
1.
Intrusion Symptoms: Recurrent, involuntary, and distressing memories, nightmares, flashbacks, or intense psychological/physical distress to trauma reminders.
2.
Avoidance: Persistent avoidance of stimuli associated with the trauma (thoughts, feelings, conversations, activities, places, people).
3.
Negative Alterations in Cognition and Mood: Inability to recall key aspects of the trauma, negative beliefs, distorted blame, persistent negative emotional state, diminished interest, detachment.
4.
Alterations in Arousal and Reactivity: Irritable behavior, hypervigilance, exaggerated startle response, problems with concentration, sleep disturbance.
Answer Rationale
Key Point! Option ④ directly describes one symptom from
Cluster 1 (Intrusion) – "recurrent nightmares about combat experiences" – and one from
Cluster 2 (Avoidance) – "avoidance of military-related discussions." This combination is highly specific to PTSD, especially in a military veteran context, as it directly links the symptoms to the traumatic event. This makes it the
most indicative finding.
Distractor Analysis
Watch out for confusion! It's crucial to differentiate PTSD from other common psychiatric conditions.
- Option ①: "Feeling sad and hopeless... decreased appetite" are classic symptoms of Major Depressive Disorder (MDD). While depression can be comorbid with PTSD, these symptoms alone are not specific to trauma.
- Option ②: "Difficulty concentrating" and "frequent headaches" are non-specific and can be seen in generalized anxiety, stress, or even medical conditions. They lack the direct link to trauma re-experiencing or avoidance.
- Option ③: "Episodes of elevated mood alternating with periods of depression" is the hallmark of Bipolar Disorder, which involves distinct manic or hypomanic episodes, not triggered solely by trauma.
Related Concepts
Assessment for PTSD should be trauma-informed, creating a safe environment. The
PTSD Checklist for DSM-5 (PCL-5) is a common screening tool. Nursing care focuses on establishing safety and trust, providing psychoeducation, and supporting evidence-based therapies like
Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) or
Eye Movement Desensitization and Reprocessing (EMDR).
Concept Summary
| Disorder | Core Feature | Key Symptoms (Examples) |
|---|
| Post-Traumatic Stress Disorder (PTSD) | Response to a traumatic event | Intrusive memories/nightmares, avoidance, negative mood, hyperarousal |
| Major Depressive Disorder (MDD) | Persistent depressed mood or anhedonia | Sadness, hopelessness, anhedonia, weight/appetite change, fatigue |
| Generalized Anxiety Disorder (GAD) | Excessive, uncontrollable worry | Restlessness, fatigue, difficulty concentrating, muscle tension, sleep disturbance |
| Bipolar Disorder | Cycling between manic and depressive episodes | Mania: elevated mood, grandiosity, decreased need for sleep. Depression: low mood, fatigue. |
Side-by-Side Comparison!
| Symptom | Indicative of PTSD? | Why or Why Not? |
|---|
| Recurrent nightmares of a car accident | Yes | Direct intrusive re-experiencing of a traumatic event. |
| Persistent low mood for 2 weeks | No (More indicative of MDD) | Lacks the trauma link; a core feature of depression. |
| Avoiding bridges after a bridge collapse | Yes | Active avoidance of trauma-related stimuli. |
| Hypervigilance in crowded places | Yes | Alteration in arousal/reactivity, common after trauma. |

- Neurobiology: PTSD involves dysregulation of the amygdala (fear center), hippocampus (memory), and prefrontal cortex
