A nurse returns home after serving in a war zone. Three months later, she experiences intrusive memories, insomnia, depression, and loss of appetite. The nurse is likely suffering from what?

1. A

   Post-Traumatic Stress Disorder (PTSD)

2. B

   Severe depression

3. C

   Adjustment disorder

4. D

   Acute Stress Reaction

Appeared in: KGMU 2023

Explanation

• The diagnosis is Post-Traumatic Stress Disorder (PTSD) because the symptoms have persisted for three months, which is longer than the one-month threshold for an Acute Stress Disorder diagnosis.
• The symptom cluster, including intrusive memories (re-experiencing the trauma), insomnia (hyperarousal), and depression (negative alterations in mood), is characteristic of PTSD following a significant traumatic event like serving in a war zone.
• The key diagnostic criterion separating PTSD from Acute Stress Disorder is the duration of the disturbance. Symptoms lasting more than one month point to PTSD.

Why Other Options Were Wrong

• Option B: While depression is a symptom, the presence of intrusive memories directly linked to the trauma is a hallmark of PTSD, making it a more specific diagnosis than severe depression alone.
• Option C: Adjustment disorder is a response to an identifiable stressor, but the symptoms are generally less severe and do not include the specific re-experiencing phenomena (intrusive memories) seen in PTSD. The trauma of a war zone is typically considered severe enough to precipitate PTSD.
• Option D: This diagnosis is incorrect because the symptoms have lasted for three months. Acute Stress Reaction (or Disorder) is diagnosed when symptoms last from three days up to a maximum of one month following the traumatic event.

Clinical Relevance

• Nursing practice connection: Safe nursing care depends on performing Differential diagnosis of trauma- and stressor-related disorders based on symptom duration and characteristics in the correct sequence, documenting the action clearly, and monitoring for the expected response.
• Nurses must be vigilant in screening for PTSD in high-risk populations, including veterans, first responders, and victims of violence, as early intervention improves outcomes.
• Untreated PTSD in a healthcare professional can pose a patient safety risk due to potential cognitive impairments, emotional dysregulation, and burnout.
• What if? If the nurse's symptoms had started only two weeks ago, the most likely diagnosis would be Acute Stress Reaction, and the focus would be on immediate support and monitoring to see if symptoms resolve within the month or progress to PTSD.

How to Approach the Question

• First, identify the key components of the clinical scenario: the patient's history (trauma: 'war zone'), the presenting symptoms ('intrusive memories, insomnia, depression'), and the timeline ('three months later').
• Second, analyze the timeline. The three-month duration is a critical clue.
• Third, evaluate the options based on diagnostic criteria. Recall that Acute Stress Reaction is short-term (less than one month).
• Fourth, recognize that symptoms lasting longer than one month after a trauma point towards PTSD.
• Finally, differentiate from other diagnoses. The presence of 'intrusive memories' makes PTSD more specific than 'severe depression' or 'adjustment disorder' in this context.

Concept Tested & Keywords

• Concept Tested: Differential diagnosis of trauma- and stressor-related disorders based on symptom duration and characteristics.
• Stem keywords: war zone, three months later, intrusive memories, insomnia, depression, loss of appetite
• Lead-in keywords: likely suffering from
• Clinical cues: The timeline 'three months later' is the most critical piece of information for differentiating between PTSD and Acute Stress Reaction.
• Clinical cues: The symptom 'intrusive memories' points specifically to a trauma-related disorder rather than general depression.
