Understanding personality disorders is essential for every nurse, especially those preparing for the NCLEX or building a solid nursing bundle of mental health knowledge. Patients with personality disorders often have long-standing patterns of thinking, feeling, and behaving that make daily functioning — and caregiving — more challenging.
As a registered nurse (RN nurse), you may care for these patients in a wide variety of settings, including psychiatric units, med-surg floors, and community care. This guide breaks down the most common types, their traits, and practical care tips.
🧠 What Are Personality Disorders?
Personality disorders are mental health conditions where a person’s thoughts and behaviors differ significantly from social expectations. These patterns are:
- Inflexible
- Long-lasting
- Cause distress or difficulty in relationships
They are grouped into three clusters: A, B, and C. Understanding the clusters will help you on the NCLEX, especially when choosing interventions in clinical scenarios.
🧩 Cluster A (Odd or Eccentric Behavior)
1. Paranoid Personality Disorder
- Distrusts others without real evidence
- Suspicious and hypersensitive
- May interpret friendly gestures as threats
Nursing care tip: Be direct and honest. Avoid jokes or sarcasm.
2. Schizoid Personality Disorder
- Emotionally detached
- Prefers being alone
- Limited interest in relationships
Nursing care tip: Respect their need for space. Don’t force social interaction.
3. Schizotypal Personality Disorder
- Odd beliefs or magical thinking
- Eccentric appearance or speech
- Socially anxious
Nursing care tip: Use clear communication. Avoid challenging their beliefs.
