Defense Mechanisms
Reaction patterns that protect a person from anxiety. All are unconscious except suppression — and the exam gives a quote and asks which one.
Naming the mechanism, in order
Find the feeling, then ask where it went
Say it like this
The quote or behavior names the mechanism
Splitting is commonly associated with borderline personality disorder.
Repression or suppression?
Is the client aware of it?
| Repression | Suppression | |
|---|---|---|
| Awareness | Unconscious | Conscious — the only one |
| Sounds like | Cannot remember the abuse | Chooses not to think about it now |
Projection or displacement?
Where does the feeling land?
| Projection | Displacement | |
|---|---|---|
| What moves | Own feeling pinned on someone else | Feeling aimed at a safer target |
| Sounds like | "He hates me" instead of "I hate him" | Angry at the boss, kicks the dog |
Rationalization or intellectualization?
An excuse or a retreat into facts?
| Rationalization | Intellectualization | |
|---|---|---|
| What it does | Gives a plausible excuse for behavior | Uses facts and analysis to avoid feelings |
| Sounds like | "I didn't want that promotion anyway." | Researches every detail, shows no emotion |

Nursing response
Unconscious, except suppression. Find the feeling, then where it went — onto someone else (projection), a safer target (displacement), an excuse (rationalization), facts (intellectualization) or something useful (sublimation). Acknowledge the feeling; never argue with the defense.

Defense Mechanisms
Defense mechanisms are mostly unconscious reaction patterns that protect a person from the anxiety of stress and conflict, and suppression is the only one done on purpose. On the exam you are given a quote or a behavior and asked to name the mechanism, so focus on the pairs that look alike. Repression blocks a memory without awareness, while suppression is a conscious choice to set a thought aside. Projection puts your own feeling onto someone else, while displacement aims a feeling at a safer target, like yelling at a spouse after a bad day with the boss. Rationalization offers a believable excuse, while intellectualization hides in facts to avoid feeling. Denial is a common first response to bad news and protects the person at first, but it becomes a problem when it keeps them from care. Sublimation, channeling a strong urge into something useful like sports, is one of the healthiest. The nurse never argues with a defense; acknowledge the feeling underneath and support healthier coping.
