Psych & Mental Health – NCLEX-RN Study Guide


Overview

This study guide covers the core psychiatric and mental health nursing concepts tested on the NCLEX-RN, including therapeutic communication techniques, major psychiatric disorders, psychopharmacology, crisis intervention, and foundational mental health concepts. Mastery of these topics requires understanding both the clinical knowledge and the prioritized nursing actions that reflect safe, patient-centered care.

Therapeutic Communication


Key Concepts

Therapeutic communication is a goal-directed, patient-centered exchange designed to promote the patient's well-being and gather assessment data. Every nurse response should encourage expression, demonstrate empathy, and avoid shutting down conversation.


Core Techniques

  • • Reflection – Mirrors the patient's feelings back to them to validate and encourage further expression

    • - Example: Patient: "Nobody cares about me." Nurse: "It sounds like you're feeling alone and uncared for."

  • • Open-ended questions – Invite free elaboration; provide richer assessment data

    • - Example: "Tell me more about what you've been experiencing."

  • • Silence – Conveys presence and acceptance; gives the patient time to think and formulate thoughts without feeling rushed
  • • Clarification – Ensures mutual understanding of what the patient is communicating
  • • Focusing – Directs conversation to a specific, important topic

    • Non-Therapeutic Blocks to Avoid

  • • False reassurance – "Everything will be just fine" dismisses concerns without basis and discourages further communication
  • • Giving advice – Removes patient autonomy and problem-solving opportunity
  • • Changing the subject – Signals disinterest and avoids important content
  • • Clichés – Minimize the patient's experience
  • • Closed-ended questions – Limit responses to yes/no, reducing assessment data

    • Key Terms

  • • Reflection – Technique of restating the patient's emotional content to encourage elaboration
  • • Open-ended question – A question that cannot be answered with yes/no; promotes free expression
  • • False reassurance – A non-therapeutic response that dismisses patient concerns with unfounded optimism

    • > Watch Out For: The NCLEX frequently asks you to identify the best or most therapeutic response. Eliminate any response that gives advice, offers false reassurance, changes the subject, or closes down communication. Always prioritize responses that acknowledge feelings and invite further sharing.

    Psychiatric Disorders


    Schizophrenia Spectrum


    #### Key Concepts

  • • Delusion – A fixed false belief not supported by reality (a thought disorder)
  • • Hallucination – A false sensory perception with no external stimulus (can be auditory, visual, tactile, olfactory, or gustatory)
  • • The most common hallucination in schizophrenia is auditory
  • • Command auditory hallucinations (voices telling the patient to harm self or others) = immediate safety priority

    • #### Nursing Priority with Command Hallucinations

    1. Assess the patient's intent to obey the command

    2. Implement safety measures immediately

    3. Do not leave the patient alone; remove access to means of harm


    Personality Disorders


    #### Borderline Personality Disorder (BPD) vs. Bipolar Disorder


    | Feature | BPD | Bipolar Disorder |

    |---|---|---|

    | Mood shift trigger | Interpersonal events | Endogenous/cycling |

    | Duration of mood shifts | Hours | Days to weeks |

    | Core fear | Fear of abandonment | Not a defining feature |

    | Identity disturbance | Yes (chronic) | Not a core feature |

    | Impulsivity | Yes | During episodes only |


    Obsessive-Compulsive Disorder (OCD)

  • • Obsession – Intrusive, unwanted, recurring thought that causes anxiety
  • • Compulsion – Repetitive behavior performed to neutralize the anxiety caused by the obsession
  • • The patient typically recognizes the behavior as excessive but feels unable to stop (ego-dystonic)
  • • Nursing focus: Do not abruptly stop the ritual; work to reduce anxiety through alternative coping

    • Eating Disorders


    | Feature | Anorexia Nervosa | Bulimia Nervosa |

    |---|---|---|

    | Body weight | Significantly low | Typically normal or above normal |

    | Core behavior | Restriction of intake | Recurrent binge-purge cycles |

    | Body image distortion | Severe | Present but less extreme |

    | Physical complications | Bradycardia, lanugo, amenorrhea | Erosion of tooth enamel, electrolyte imbalances (hypokalemia) |


    Alzheimer's Disease Stages


    | Stage | Key Features |

    |---|---|

    | Early (Mild) | Short-term memory loss, word-finding difficulty, maintained ADLs |

    | Middle (Moderate) | Confusion, wandering, personality changes, needs assistance with ADLs |

    | Late (Severe) | Unable to perform ADLs independently, incontinence, may lose speech, requires full-time supervision and care |


    Key Terms

  • • Delusion – Fixed false belief not based in reality
  • • Hallucination – False sensory perception without external stimulus
  • • Command hallucination – Auditory hallucination directing the patient to act; highest safety priority
  • • Compulsion – Repetitive act performed to reduce obsessive anxiety
  • • Ego-dystonic – Behavior recognized by the patient as unwanted or irrational (as in OCD)

    • > Watch Out For: Do not confuse delusions (thought content) with hallucinations (sensory experience). On the NCLEX, any patient reporting command hallucinations requires an immediate safety assessment as the priority action—this supersedes all other nursing interventions.

    Psychopharmacology


    Lithium (Mood Stabilizer)


    #### Therapeutic vs. Toxic Levels


    | Level | Range |

    |---|---|

    | Therapeutic (maintenance) | 0.6–1.2 mEq/L |

    | Therapeutic (acute mania) | 0.8–1.4 mEq/L |

    | Toxic | > 1.5 mEq/L |

    | Severely toxic | > 2.0 mEq/L |


  • • Early toxicity signs: Nausea, vomiting, fine tremor, diarrhea, drowsiness
  • • Severe toxicity signs: Coarse tremor, ataxia, confusion, seizures, cardiac dysrhythmias
  • • Nursing actions at 1.8 mEq/L: Hold the dose, notify the provider, monitor vitals and neuro status, prepare for hydration/dialysis if needed
  • • Lithium is renally cleared; maintain adequate sodium and fluid intake to prevent toxicity

    • Antipsychotics


    #### Neuroleptic Malignant Syndrome (NMS)

  • • Most life-threatening side effect of antipsychotic medications
  • • Cardinal signs (HALT):

    • - Hyperthermia (high fever)

    - Autonomic instability (diaphoresis, labile BP, tachycardia)

    - Lead-pipe muscle rigidity

    - Altered level of consciousness

  • • Action: Discontinue antipsychotic immediately, notify provider, provide supportive care

    • #### Extrapyramidal Symptoms (EPS)

    Most commonly caused by first-generation (typical) antipsychotics (e.g., haloperidol, chlorpromazine)


    | EPS Type | Description | Treatment |

    |---|---|---|

    | Akathisia | Intense motor restlessness; uncontrollable urge to move | Beta-blockers, benzodiazepines |

    | Dystonia | Sudden, painful muscle spasms (neck, tongue, eyes) | Anticholinergics (Benadryl, Cogentin) |

    | Pseudoparkinsonism | Tremor, rigidity, shuffling gait, bradykinesia | Anticholinergics |

    | Tardive Dyskinesia (TD) | Late-onset, involuntary repetitive movements of face/tongue; may be irreversible | Reduce/change medication |


    #### Clozapine (Clozaril) – Atypical Antipsychotic

  • • Unique risk: Agranulocytosis (severe, potentially fatal neutropenia)
  • • Signs: Sore throat, fever, mouth sores
  • • Priority action: Obtain WBC and ANC count immediately; notify provider
  • • Requires mandatory weekly WBC monitoring (REMS program)

    • MAOIs (Monoamine Oxidase Inhibitors)

  • • Examples: Phenelzine, tranylcypromine
  • • Mechanism of risk: MAOIs block monoamine oxidase, the enzyme that metabolizes tyramine; excess tyramine causes massive catecholamine release → hypertensive crisis
  • • Tyramine-rich foods to AVOID: Aged cheeses, cured/smoked meats, red wine, beer, soy sauce, fermented foods
  • • Hypertensive crisis signs: Severe headache, stiff neck, nausea, diaphoresis, dangerously elevated BP

    • SSRIs (Selective Serotonin Reuptake Inhibitors)

  • • Mechanism: Block presynaptic reuptake of serotonin → increased serotonin availability at the synapse
  • • Therapeutic antidepressant effects: Typically seen in 2–4 weeks
  • • Serotonin Syndrome (too much serotonin): Agitation, tremor, hyperthermia, diaphoresis, clonus — a medical emergency

    • Key Terms

  • • Lithium toxicity – Serum level >1.5 mEq/L; requires immediate intervention
  • • NMS – Potentially fatal reaction to antipsychotics; characterized by hyperthermia, rigidity, AMS, autonomic instability
  • • Agranulocytosis – Dangerously low WBC/neutrophil count; primary risk of clozapine
  • • Akathisia – Motor restlessness EPS; most commonly caused by typical antipsychotics
  • • Tardive Dyskinesia – Late-onset, potentially irreversible involuntary movements; associated with long-term antipsychotic use
  • • Hypertensive crisis – Life-threatening BP elevation; risk with MAOIs + tyramine

    • > Watch Out For:

    > - NMS vs. Serotonin Syndrome: NMS features lead-pipe rigidity and is slower in onset; Serotonin Syndrome features clonus/myoclonus and rapid onset. Both are emergencies.

    > - Akathisia vs. anxiety: Patients with akathisia are often misdiagnosed as anxious. Always assess movement patterns.

    > - NCLEX loves testing the lithium therapeutic range — memorize 0.6–1.2 mEq/L for maintenance.

    > - SSRIs take 2–4 weeks for antidepressant effect, but anxiety/agitation may appear early — this is an important patient education point.

    Crisis Intervention & Safety


    Suicide Risk Assessment


    #### IS PATH WARM Mnemonic

    | Letter | Meaning |

    |---|---|

    | I | Ideation |

    | S | Substance abuse |

    | P | Purposelessness |

    | A | Anxiety |

    | T | Trapped |

    | H | Hopelessness |

    | W | Withdrawal |

    | A | Anger |

    | R | Recklessness |

    | M | Mood changes |


  • • Highest immediate risk indicator: Having a specific plan AND access to lethal means
  • • Direct questioning about suicide does NOT increase risk — it is a required safety assessment
  • • When a patient says something like "my family would be better off without me," always directly ask: "Are you thinking about harming yourself or ending your life?"

    • Duty to Warn (Tarasoff Principle)

  • • When a patient discloses a specific, credible plan to harm an identifiable third party, the nurse has a legal and ethical obligation to:

    • 1. Notify the provider

    2. Notify the intended victim

    3. Notify law enforcement

  • • This legally overrides patient confidentiality to protect a third party from harm

    • Agitation & Least-Restrictive Intervention Principle

    Interventions must be applied from least to most restrictive:


    1. Verbal de-escalation (calm voice, clear boundaries, offering choices) — always first

    2. Medication (oral, then IM if refused)

    3. Seclusion (supervised isolation without restraints)

    4. Physical restraints (last resort only)


    Legal Requirements for Physical Restraints

  • • Provider order required (in most states, within 1 hour of application)
  • • Patient assessed every 15 minutes (or per facility policy)
  • • Restraints released every 2 hours for ROM exercises, circulation checks, and toileting
  • • Continuous documentation required throughout
  • • Restraints must never be used as punishment or for staff convenience

    • Alcohol Withdrawal Timeline


    | Time Frame | Manifestations |

    |---|---|

    | 6–12 hours | Tremors, anxiety, diaphoresis, tachycardia |

    | 12–24 hours | Hallucinations (visual, auditory, tactile) |

    | 24–72 hours | Peak risk: Delirium Tremens (DTs), seizures |

    | 48–96 hours | Symptoms begin to subside |


  • • Priority nursing diagnosis: Risk for injury related to seizures
  • • Treatment: Benzodiazepines (e.g., lorazepam, diazepam) per protocol

    • Key Terms

  • • IS PATH WARM – Suicide risk assessment mnemonic
  • • Duty to warn (Tarasoff) – Legal obligation to protect identifiable third parties from a patient's credible threat
  • • Least-restrictive intervention – Principle requiring the use of the mildest effective intervention before escalating
  • • Delirium Tremens (DTs) – Severe alcohol withdrawal syndrome peaking at 24–72 hours; life-threatening

    • > Watch Out For:

    > - On the NCLEX, verbal de-escalation always comes before restraints. Even if the patient appears threatening, restraints are never the first action.

    > - Know that duty to warn overrides confidentiality — this is frequently tested.

    > - For alcohol withdrawal, note that DTs peak at 24–72 hours, not immediately. A patient who "last drank 48 hours ago" is in the highest-risk window.

    Mental Health Concepts


    Defense Mechanisms


    | Mechanism | Definition | Example |

    |---|---|---|

    | Projection | Attributing one's own unacceptable feelings to another person | "He hates me" (when the patient actually feels hostility) |

    | Displacement | Redirecting emotions from original source to a safer target | Kicking a chair after being angry at a boss |

    | Denial | Refusing to acknowledge a painful reality | "I don't have a drinking problem" |

    | Rationalization | Creating logical explanations to justify unacceptable behavior | "I drink because work is stressful" |

    | Regression | Reverting to behaviors of an earlier developmental stage | An adult throwing a tantrum under stress |

    | Sublimation | Channeling unacceptable impulses into socially acceptable activities | Channeling aggression into competitive sports |

    | Repression | Unconsciously pushing painful memories out of awareness | No memory of a traumatic event |


    Grief vs. Major Depressive Disorder (MDD)


    | Feature | Grief | MDD |

    |---|---|---|

    | Mood | Comes in waves; linked to thoughts of the deceased | Pervasive, most of the day, nearly every day |

    | Self-esteem | Preserved | Diminished; feelings of worthlessness |

    | Functional impairment | Temporary, expected | Significant and sustained |

    | Positive emotions | Can experience moments of happiness | Anhedonia; rarely experiences positive affect |


    Key Terms

  • • Projection – Attributing one's unacceptable feelings to others
  • • Displacement – Redirecting emotion to a substitute target
  • • Anhedonia – Inability to feel pleasure; a hallmark feature of MDD
  • • Bereavement – Normal grief response to loss; does not inherently require psychiatric treatment

    • > Watch Out For:

    > - Projection vs. Displacement: Projection is about attributing feelings to others; Displacement is about redirecting feelings to a different target. These are commonly confused on the NCLEX.

    > - The critical differentiator between grief and MDD is **self-
