Nursing Field Notes / Mental Health · Anxiety-Spectrum Disorders
PTSD 🌩️
& Acute Stress Disorder (ASD)
NG-078MENTAL HEALTHADHD-friendly visual edition
Both ASD and PTSD are anxiety-spectrum responses that can develop after exposure to a traumatic event. One clock separates them: symptoms in the first month = ASD; symptoms past one month = PTSD. Four symptom clusters describe the whole clinical picture, and the nurse's first job — every time — is a safety check before anything else.
Same trauma-response biology — the only thing that changes the diagnosis is the calendar.
🕐 ASD → PTSD: one timeline, one cutoff
🧠 “Under a month = ASD. Over a month = PTSD.” Same symptom clusters both sides of the line — only the duration changes the label.
🧬 What counts as "trauma" (diagnostic criteria)
Directly experiencing a threat to life, serious injury, or sexual violence
Witnessing the event happen to someone else
Learning it happened to a close family member or friend
Repeated professional exposure to trauma details (e.g., first responders)
🧠 Keep assessment clinical and non-graphic — you do not need event detail to identify the diagnosis or plan safe care.
⚠️ Risk factors that raise likelihood
Prior trauma history
Lack of social support after the event
Co-occurring substance use
Severity/duration of the traumatic exposure

CLUES
STEP 2 · FOUR CLUSTERS
Four symptom clusters cover the whole clinical picture — plus the physiology behind a flashback.
🧩 The 4 symptom clusters — memorize this grid
🧠 “I AM H” — Intrusion · Avoidance · Mood/cognition (negative) · Hyperarousal. All four must be present for the PTSD diagnosis, not just one.
🚨 A trauma reminder can trigger a full sympathetic surge
🧠 A war veteran hearing a car backfire and feeling like they're back in combat is hyperarousal + intrusion firing together — reassure them of present safety first.
🗣️ Say this — priority response example
Client: "The war was years ago, but I still remember my friends who were killed. I don't know why I lived and they died."
Nurse's priority response: "Are you having any thoughts of harming yourself?"
🧠 Survivor's guilt is a red flag for self-harm risk. Always screen for safety before exploring the feeling further.
⭐ Assessment priorities beyond safety
Self-harm: thoughts or plans
Substance use (drugs & alcohol) — common coping attempt
Relationships with family & friends — isolation is a warning sign
For sexual assault survivors: assess for guilt/shame; reinforce they could not have anticipated it and did not deserve it

CARE
STEP 3 · PACE & PROCESS
Let the client set the pace, normalize the reaction, and lean on trauma-focused therapy before medication.
✅ Nursing priority ladder
1
Safety screen first — self-harm/suicidal ideation, every encounter
2
Encourage the client to talk at their own pace — never force detail before they're ready
3
Explain that difficult symptoms after trauma are normal — normalize, don't pathologize the reaction
4
Assess substance use and relationships — common coping/withdrawal patterns
5
Connect to trauma-focused therapy — CBT, EMDR, or group therapy as tolerated
🧠 “Pace, Place, Process.” Let them set the pace, keep them safe in place, then help them process — in that order.
⭐ Trauma-focused therapy — first-line, non-drug
Trauma-focused CBT — helps the client reframe distorted trauma-related beliefs (guilt, danger, self-blame) and gradually process memories.
EMDR (Eye Movement Desensitization and Reprocessing) — the client recalls the trauma in brief segments while following bilateral stimulation (e.g., guided eye movements); thought to help the brain reprocess the memory so it feels less distressing.
Prolonged exposure therapy — structured, repeated recounting of the memory in a safe setting to reduce its emotional charge over time.
🧠 CBT is a type of talk therapy that helps clients reframe thought processes to prevent negative thought patterns and adapt to stress and anxiety.
🧠 Avoid long-term benzodiazepines in PTSD — dependence risk, and evidence doesn't support them as an effective core treatment; they don't treat the underlying avoidance/re-experiencing symptoms.
🚨 Never do this with a trauma client
Never push the client to describe trauma details before they're ready
Never minimize the reaction ("it was years ago, just move on")
Never assume every trauma survivor's symptoms look the same
✅ Do reinforce: the feelings are a normal response to an abnormal event
✅ For assault survivors: reinforce they could not have anticipated it and did not deserve it
