📚 Defense Mechanisms — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Defense mechanisms are unconscious mental strategies the ego uses to reduce anxiety and protect against distressing thoughts or feelings. They are normal in moderation but become maladaptive when overused or when they distort reality. NCLEX commonly asks the student to identify the mechanism from a behavioral example.
🔑
Key points
Understand these first
Denial is refusing to accept reality (a new diabetic insisting nothing is wrong).
Projection attributes one's own unacceptable feelings to others (accusing the spouse of the anger you feel).
Displacement shifts feelings from the real source to a safer target (yelling at the dog after a bad day at work).
Rationalization offers logical-sounding excuses to justify behavior; intellectualization focuses on facts to avoid the emotion.
Regression returns to earlier developmental behaviors (a hospitalized child wetting the bed); sublimation channels impulses into acceptable outlets (anger into exercise).
Reaction formation expresses the opposite of true feelings; identification, repression, and suppression are also commonly tested.

Nursing priorities
What to do, in order
Identify the specific mechanism from the client's behavior without labeling it judgmentally.
Accept the client's use of defenses early in coping rather than confronting them harshly.
Help the client recognize maladaptive patterns and develop healthier coping skills over time.
Sublimation is the healthiest, most mature mechanism; reinforce adaptive coping.
🚩
Red flags — report now
Escalate immediately
Prolonged denial that prevents needed treatment (refusing care) requires intervention.
Do not aggressively confront or strip away a defense mechanism a client needs early in a crisis.
🗣️
Patient teaching
What patients must know

Channeling strong emotions into productive activity (exercise, art, work) is a mature way to cope.
