NCLEX PART 3

CH 10. Psychiatric & Final Review

Congratulations! You have reached the final chapter.

Psychiatric Nursing is about Safety and Communication.
Never ask "Why?" and never say "Don't worry."

We also included the "Must-Know Lab Values" at the end.
Good luck, future RN!

1. Therapeutic Communication

The NCLEX wants you to be empathetic but professional. Avoid "Non-therapeutic" blocks.

Technique	Example & Rationale
Do NOT ask "Why?"	Wrong: "Why are you so angry?" Right: "I see you are upset. Tell me more." ("Why" makes the patient defensive.)
Do NOT give False Reassurance	Wrong: "Don't worry, everything will be fine." Right: "We are here to help you." (False hope destroys trust.)
Use "Open-Ended" Questions	Right: "How are you feeling today?" (Avoid Yes/No questions unless assessing suicide risk.)
Silence	Right: Sitting quietly with a grieving client. (Silence is powerful. Don't rush to fill the void.)

2. Psych Pharmacology (Danger Zones)

Psych meds have serious side effects. Know these three.

Lithium (Bipolar):
- Therapeutic Level: 0.6 - 1.2 mEq/L.
- Toxicity (>1.5): Tremors, N/V, Confusion.
- Diet: Do NOT restrict Sodium (Low Na = High Lithium Toxicity). Drink 2-3L water.
Clozapine (Schizophrenia):
- Risk: Agranulocytosis (Severe drop in WBCs).
- Action: Report sore throat or fever immediately!
- Weekly WBC monitoring required.
MAOIs (Antidepressants):
- (e.g., Phenelzine, Tranylcypromine)
- Diet: NO Tyramine (Aged cheese, wine, cured meats).
- Risk: Hypertensive Crisis.

3. Defense Mechanisms

How do people cope with stress? You need to identify the behavior.

Projection:
Attributing one's own unacceptable feelings to someone else.
(e.g., A cheating husband accuses his wife of cheating.)
Displacement:
Transferring anger to a "safer" target.
(e.g., Kicking the dog after a bad day at work.)
Rationalization:
Making excuses to justify behavior.
(e.g., "I failed because the teacher hates me," not because I didn't study.)

4. FINAL REVIEW: Lab Values

Memorize these numbers. Write them down on your whiteboard when the exam starts.

Test	Normal Range	Significance
Potassium (K+)	3.5 - 5.0 mEq/L	< 3.5 or > 5.0 affects the HEART.
Sodium (Na+)	135 - 145 mEq/L	Changes affect the BRAIN (LOC).
Calcium (Ca++)	8.5 - 10.5 mg/dL	Muscles. Low = Tetany.
Magnesium (Mg)	1.5 - 2.5 mEq/L	"Mellows" muscles. Low = Wild (Torsades).
Creatinine	0.6 - 1.2 mg/dL	Best indicator of Kidney function.
WBC	5,000 - 10,000	High = Infection. Low = Neutropenia.
Platelets	150,000 - 400,000	< 100k = Bleeding risk.
