Post-Traumatic Stress Disorder: What Nurses Must Know

PTSD develops after exposure to a traumatic event — combat, assault, accidents, natural disasters, childhood abuse, or witnessing violence. It affects ~6% of the U.S. population at some point in their lives, with higher rates in veterans, first responders, and sexual assault survivors.

🔍 Core Symptom Clusters (DSM-5)

1. Intrusion symptoms:

• Flashbacks (feeling like the trauma is happening again)

• Nightmares

• Intrusive, distressing memories

• Intense psychological/physiological distress at trauma reminders

2. Avoidance:

• Avoiding thoughts, feelings, or conversations about the trauma

• Avoiding people, places, or activities that trigger memories

3. Negative alterations in cognition and mood:

• Persistent negative beliefs ("The world is dangerous," "It was my fault")

• Detachment from others, emotional numbness

• Inability to recall key aspects of the trauma

• Loss of interest in previously enjoyed activities

4. Hyperarousal:

• Hypervigilance (constantly scanning for danger)

• Exaggerated startle response

• Irritability or angry outbursts

• Sleep disturbance

• Difficulty concentrating

Symptoms must persist >1 month and cause significant impairment. If <1 month, consider Acute Stress Disorder.

🏥 Priority Nursing Interventions

1. Create safety — physical and emotional. This is the foundation of all PTSD care

2. Ask before touching. Always announce what you're doing. "I'm going to take your blood pressure on your left arm now"

3. Recognize triggers:

   • Loud noises, sudden movements, specific smells

   • Being restrained or feeling trapped

   • Physical exams (especially for sexual trauma survivors)

   • Authority figures, uniforms

4. During a flashback:

   • Stay calm, speak slowly: "You are in the hospital. It is 2026. You are safe"

   • Encourage grounding — feel the chair, name the room, hold ice cubes

   • Do NOT touch without permission or restrain

5. Allow the patient control whenever possible — choice of seating, door open/closed, who is in the room

6. Screen for co-occurring conditions: depression (very common), substance use, suicidal ideation, TBI (in veterans)

🗣️ Patient & Family Education

• PTSD is a normal response to abnormal events — it is not weakness

• Evidence-based therapies: CPT (Cognitive Processing Therapy), PE (Prolonged Exposure), and EMDR (Eye Movement Desensitization and Reprocessing)

• Recovery is possible but takes time — setbacks are normal, not failure

• Families should learn about triggers and avoid saying "just get over it"

• Crisis resources: Veterans Crisis Line: 988 (press 1) | Crisis Text Line: Text HOME to 741741

🏥 Trauma-Informed Care Principles

Apply these to every patient — you often don't know who has trauma history:

1. Safety — physical and emotional

2. Trustworthiness — consistency, clear communication

3. Choice — give patients control where possible

4. Collaboration — work with, not on, the patient

5. Empowerment — build on strengths, not deficits

"Trauma-informed care isn't a technique. It's a lens through which you see every patient."

Managing Anxiety Disorders: A Nursing Guide

Anxiety disorders are the most common mental illness in the U.S., affecting 40 million adults. Types include Generalized Anxiety Disorder (GAD), Panic Disorder, Social Anxiety, and Phobias.

🏥 Priority Nursing Interventions

1. Stay calm yourself. Anxiety is contagious — your composure is therapeutic

2. Use grounding techniques:

   • 5-4-3-2-1 method: Name 5 things you see, 4 you hear, 3 you can touch, 2 you smell, 1 you taste

   • Box breathing: Inhale 4 sec → Hold 4 sec → Exhale 4 sec → Hold 4 sec

   • Progressive muscle relaxation

3. Reduce environmental stimuli — dim lights, quiet room, limit visitors during acute episodes

4. Use short, clear statements. "You are safe. I am here. Breathe with me."

5. Encourage regular exercise, sleep, and caffeine reduction — these are evidence-based interventions

6. Assess for co-occurring depression and substance use — extremely common overlap

💊 Medications

⚠️ Benzo overdose: Treat with Flumazenil — but use cautiously in chronic benzo users (can precipitate seizures)

🗣️ Patient Education

• Anxiety is treatable — most patients improve significantly with proper care

• Avoidance reinforces anxiety. Gradual exposure (with therapy) is key to recovery

• Caffeine, alcohol, and cannabis can all worsen anxiety

• CBT (Cognitive Behavioral Therapy) has the strongest evidence base — encourage referral

• Develop a personal coping toolkit: breathing exercises, journaling, movement, support contacts

"Anxiety lies to your patients. Your job is to be the calm truth in the storm."

Nursing Essentials for Major Depression

Major Depressive Disorder (MDD) affects over 280 million people worldwide and is the leading cause of disability globally. Nurses play a frontline role in assessment, safety, and recovery.

🔍 Assessment: Beyond "Are You Sad?"

Use the SIG E CAPS mnemonic:

• Sleep disturbance (insomnia or hypersomnia)

• Interest loss (anhedonia)

• Guilt (excessive or inappropriate)

• Energy loss / fatigue

• Concentration impaired

• Appetite changes (increase or decrease)

• Psychomotor changes (agitation or retardation)

• Suicidal ideation

Diagnosis requires ≥5 symptoms for ≥2 weeks, with depressed mood or anhedonia being one of them.

Always screen for suicide:

• Use validated tools: PHQ-9, Columbia Suicide Severity Rating Scale (C-SSRS)

• Ask directly: "Are you thinking about hurting yourself or ending your life?" — asking does NOT increase risk

• Assess for plan, means, intent, and timeline

---

🏥 Priority Nursing Interventions

1. Safety is #1. Remove sharps, cords, belts, toxic substances. 1:1 observation if actively suicidal

2. Establish a therapeutic relationship — sit with the patient, use silence therapeutically, validate their pain

3. Encourage small, achievable goals — getting out of bed, taking a shower, eating one meal. Don't overwhelm

4. Monitor medication response — SSRIs take 2-6 weeks for full effect. Suicide risk may increase initially as energy returns before mood improves

5. Promote sleep hygiene — consistent schedule, limit screens, no caffeine after noon

6. Encourage physical activity — even 15 minutes of walking has evidence-based antidepressant effects

7. Watch for serotonin syndrome if on multiple serotonergic drugs — agitation, hyperthermia, clonus, diaphoresis

🗣️ Patient Education

• Depression is a medical illness — not weakness or laziness

• Meds need time to work — don't stop because you feel better, don't stop because you don't feel better yet

• Therapy + medication is more effective than either alone

• Relapse is common — have a crisis plan ready

• National Suicide Prevention Lifeline: 988

Understanding & Managing Schizophrenia as a Nurse

Schizophrenia is a chronic psychotic disorder affecting ~1% of the population. It typically emerges in late adolescence to early adulthood and requires lifelong management.

🔍 Key Symptoms to Assess

Positive symptoms (excess of normal function):

• Hallucinations — auditory most common ("hearing voices"). Always ask: "Are the voices telling you to hurt yourself or others?"

• Delusions — paranoid, grandiose, or persecutory. Do NOT argue with delusions

• Disorganized speech — loose associations, word salad, tangentiality

• Disorganized behavior — unpredictable agitation, bizarre posturing

Negative symptoms (deficit of normal function):

• Flat affect — limited emotional expression

• Alogia — poverty of speech

• Avolition — lack of motivation for daily tasks

• Anhedonia — inability to experience pleasure

• Social withdrawal

Negative symptoms are often harder to treat and more disabling long-term than positive symptoms.

🏥 Priority Nursing Interventions

1. Build trust slowly. Be consistent, honest, and follow through on promises. Avoid touch without permission

2. Use clear, simple, concrete language. Abstract thinking is often impaired

3. Do NOT challenge hallucinations or delusions directly. Instead: "I understand that feels very real to you. I don't hear the voices, but I want to help you feel safe"

4. Monitor for command hallucinations — these are a safety emergency

5. Promote ADLs — patients with negative symptoms need structured encouragement for hygiene, nutrition, and activity

6. Assess for suicide risk — ~5-10% of schizophrenia patients die by suicide, highest risk in early illness

---

💊 Medications

⚠️ Know your EPS:

• Acute dystonia — muscle spasms (neck, jaw, eyes). Treat with Benztropine (Cogentin) or diphenhydramine

• Akathisia — restlessness, inability to sit still. Often mistaken for worsening psychosis

• Tardive dyskinesia — involuntary facial/tongue movements. May be irreversible. Assess with AIMS scale

• Neuroleptic Malignant Syndrome (NMS) — fever, rigidity, altered mental status, elevated CK. Medical emergency — stop the med immediately

---

🗣️ Patient & Family Education

• Schizophrenia is a brain disorder, not a character flaw — reduce stigma

• Medication adherence is the #1 factor in preventing relapse

• Long-acting injectable antipsychotics (LAIs) are an option for patients who struggle with daily oral meds

• Substance use (especially cannabis and stimulants) significantly worsens psychosis

• Family support and psychoeducation dramatically improve outcomes

"Meet your patient in their reality with empathy, then guide them toward safety and stability."
