Mental Health Nursing Quiz

Test your psychiatric nursing knowledge with these 25 NCLEX-style questions on depression, schizophrenia, anxiety, and crisis situations.

25 questions | 90 minutes | 70% to pass

Question 1: A patient with major depressive disorder has not eaten, bathed, or left the bed in 3 days. The PRIORITY nursing intervention is:

  1. Leave the patient alone until they feel motivated to get up
  2. Assign the patient to lead a group therapy session to increase socialization
  3. Assist with basic self-care needs such as hygiene and nutrition using a structured, matter-of-fact approach
  4. Initiate a lengthy discussion about the patient feelings and childhood experiences

Answer: C — In severe depression, patients lack energy and motivation for basic self-care. The priority is meeting physiological needs (nutrition, hydration, hygiene) using a calm, structured, non-demanding approach. Deep psychotherapy is inappropriate during the acute phase when the patient cannot concentrate or engage.

Question 2: A nurse is monitoring a patient who started an SSRI antidepressant 5 days ago. Which finding is MOST concerning?

  1. The patient asks when the medication will start working
  2. The patient reports the medication has not improved their mood yet
  3. The patient reports mild nausea after taking the medication
  4. The patient expresses new thoughts of suicide and has been giving away personal items

Answer: D — SSRIs can take 2 to 4 weeks for full effect. During the early treatment period, patients may gain enough energy to act on suicidal thoughts before mood fully improves. New suicidal ideation with behavioral warning signs (giving away items) requires immediate safety intervention and provider notification.

Question 3: A patient with bipolar disorder in the manic phase is talking rapidly, has not slept in 72 hours, and is spending money recklessly. The PRIORITY nursing intervention is:

  1. Provide a safe, low-stimulation environment with high-calorie finger foods and set firm consistent limits
  2. Engage the patient in competitive physical activities to burn off excess energy
  3. Allow the patient to spend freely since restricting them violates autonomy
  4. Encourage the patient to attend a 2-hour group therapy lecture

Answer: A — During mania, priorities are safety (from impulsive behavior), nutrition (patient will not sit for meals - offer portable high-calorie foods), and rest. Reduce environmental stimulation. Set firm, consistent, non-argumentative limits. Competitive activities and group lectures increase agitation.

Question 4: A patient on lithium therapy reports persistent vomiting, coarse hand tremors, and blurred vision. The nurse should:

  1. Hold the lithium, check the serum level, and notify the provider immediately as these indicate toxicity
  2. Administer the next lithium dose as scheduled since these are expected side effects
  3. Give an antiemetic and continue the lithium at the current dose
  4. Encourage the patient to eat salty foods to counteract the symptoms

Answer: A — Persistent vomiting, coarse tremors (fine tremors may be expected initially), and blurred vision are signs of lithium toxicity. Therapeutic level is 0.6 to 1.2 mEq/L. Hold the dose, obtain a stat lithium level, and notify the provider. Dehydration and sodium loss worsen toxicity.

Question 5: A nurse is teaching a patient about lithium therapy. Which instruction is MOST important?

  1. Take lithium only when feeling manic and stop during stable periods
  2. Restrict all salt and fluid to prevent lithium levels from rising
  3. Lithium levels do not need monitoring once the correct dose is established
  4. Maintain consistent sodium and fluid intake daily and avoid dehydration

Answer: D — Lithium and sodium compete for reabsorption in the kidneys. Low sodium or dehydration causes the kidneys to retain more lithium, increasing blood levels and toxicity risk. Patients must maintain consistent daily salt and fluid intake and avoid excessive sweating, vomiting, or diarrhea.

Question 6: A patient on a mood stabilizer is being started on an NSAID for joint pain. The nurse should notify the provider because:

  1. NSAIDs can decrease renal lithium clearance, raising lithium levels and increasing toxicity risk
  2. NSAIDs have no interactions with mood stabilizers
  3. The combination will cause immediate seizures
  4. NSAIDs will make the mood stabilizer work faster

Answer: A — NSAIDs (ibuprofen, naproxen) reduce renal blood flow and decrease lithium excretion by the kidneys, causing lithium levels to rise into the toxic range. The provider should be notified to consider an alternative analgesic such as acetaminophen or to increase lithium level monitoring.

Question 7: A patient with schizophrenia tells the nurse that aliens are controlling their thoughts through a microchip implanted in their brain. The BEST therapeutic response is:

  1. I understand there are no aliens. That is just your illness talking.
  2. That must be very distressing for you. You are safe here. Let us talk about how you are feeling.
  3. Let me check your head for the microchip to prove it is not there.
  4. That is really interesting. Tell me more about the aliens.

Answer: B — Acknowledge the patient emotional experience (distress, fear) without reinforcing or arguing with the delusion. Do not try to logically disprove it or show curiosity that validates it. Focus on feelings and provide reassurance of safety. The patient reality feels completely real to them.

Question 8: A patient on haloperidol (a typical antipsychotic) develops sudden onset of high fever (104 F), severe muscle rigidity, altered consciousness, and tachycardia. The nurse suspects:

  1. Serotonin syndrome from an SSRI interaction
  2. Neuroleptic malignant syndrome (NMS) - a life-threatening emergency
  3. A common cold with muscle aches
  4. Expected side effects that will resolve on their own

Answer: B — NMS is a rare but life-threatening reaction to antipsychotic medications characterized by hyperthermia (above 104 F), lead-pipe muscle rigidity, altered mental status, and autonomic instability. Stop the antipsychotic immediately, notify the provider, and prepare for ICU transfer. Mortality is 10 to 20 percent without treatment.

Question 9: A patient taking a second-generation (atypical) antipsychotic has gained 30 pounds in 3 months and has a fasting blood glucose of 140 mg/dL. The nurse should:

  1. Discontinue the medication without consulting the provider
  2. Tell the patient the weight gain is unrelated to the medication
  3. Recognize these as expected metabolic side effects and report to the provider for monitoring and possible medication adjustment
  4. Encourage the patient to skip meals to offset the weight gain

Answer: C — Atypical antipsychotics (olanzapine, clozapine, quetiapine, risperidone) commonly cause metabolic syndrome: weight gain, hyperglycemia, dyslipidemia, and increased diabetes risk. Regular monitoring of weight, glucose, and lipids is essential. Report significant changes for possible dose adjustment or medication switch.

Question 10: A patient on an antipsychotic exhibits involuntary lip smacking, tongue protrusion, and facial grimacing. The nurse recognizes this as:

  1. Normal facial expressions during conversation
  2. A voluntary behavior the patient is using for attention
  3. Tardive dyskinesia - a potentially irreversible movement disorder requiring immediate provider notification
  4. Extrapyramidal symptoms (EPS) that are easily reversible

Answer: C — Tardive dyskinesia (involuntary, repetitive movements of the face, tongue, and jaw) is a late-onset, potentially irreversible side effect of long-term antipsychotic use. Unlike EPS (which responds to anticholinergics), tardive dyskinesia requires immediate provider notification and likely medication change.

Question 11: A patient on a typical antipsychotic develops acute dystonia with neck twisting and difficulty swallowing. The nurse should:

  1. Position the patient supine and wait for the reaction to pass
  2. Administer benztropine (Cogentin) or diphenhydramine (Benadryl) IM immediately as ordered
  3. Tell the patient to relax their muscles and it will stop
  4. Increase the antipsychotic dose to override the reaction

Answer: B — Acute dystonia (sustained involuntary muscle contractions causing twisting, abnormal postures) is a medical emergency when it affects the neck (torticollis) or throat (laryngospasm can obstruct the airway). IM benztropine or diphenhydramine provides rapid anticholinergic relief within minutes.

Question 12: A patient on a psychiatric unit begins hyperventilating and says: I am having a heart attack. I am going to die. The nurse assessment reveals no cardiac abnormalities. This is MOST consistent with:

  1. A panic attack with somatic symptoms mimicking cardiac distress
  2. A psychotic episode with somatic delusions
  3. Acute myocardial infarction requiring emergency cardiac intervention
  4. Malingering for attention from the nursing staff

Answer: A — Panic attacks produce intense physical symptoms (chest pain, palpitations, dyspnea, diaphoresis) that mimic cardiac emergencies. Once cardiac causes are ruled out, the nurse should stay calm, guide slow breathing, provide reassurance, and remain with the patient until the attack subsides (usually 10 to 30 minutes).

Question 13: A nurse is caring for a patient with generalized anxiety disorder (GAD). Which intervention is MOST appropriate?

  1. Isolate the patient in a quiet room with no human contact
  2. Teach relaxation techniques such as deep breathing, progressive muscle relaxation, and mindfulness
  3. Encourage the patient to discuss their worries in exhaustive detail repeatedly
  4. Tell the patient there is nothing to worry about and they need to stop overthinking

Answer: B — Teaching concrete coping strategies (deep breathing, progressive muscle relaxation, guided imagery, mindfulness) gives the patient practical tools to manage anxiety independently. Dismissing worries, exhaustive rumination, or isolation are all non-therapeutic and may worsen symptoms.

Question 14: A patient with PTSD becomes agitated and dissociative after hearing a loud noise on the unit. The PRIORITY nursing intervention is:

  1. Ignore the behavior since it will pass on its own
  2. Restrain the patient immediately for staff safety
  3. Use grounding techniques: speak calmly, orient the patient to the present, and encourage them to identify their surroundings
  4. Administer a sedative without assessment

Answer: C — Grounding techniques bring the dissociating patient back to present reality. Speak calmly, use their name, ask them to identify objects they can see and feel, remind them of the current safe location. This reduces the flashback intensity without retraumatizing or using unnecessary physical or chemical restraints.

Question 15: A patient with OCD spends 3 hours performing handwashing rituals each morning and is unable to attend therapy sessions. The nurse should:

  1. Forcibly stop the patient from washing and lock the bathroom
  2. Encourage the patient to wash even longer to fully satisfy the compulsion
  3. Allow reasonable time for rituals while gradually working with the patient and treatment team to reduce ritual duration
  4. Shame the patient into stopping by pointing out how irrational the behavior is

Answer: C — Abruptly stopping rituals causes severe anxiety and is counterproductive. The therapeutic approach gradually reduces ritual time while implementing exposure and response prevention (ERP) therapy. The nurse provides a calm, nonjudgmental environment and collaborates with the treatment team on behavioral goals.

Question 16: A patient admitted for suicidal ideation tells the nurse: I have 30 oxycodone pills hidden at home and plan to take them all tonight when I get out. The HIGHEST priority is:

  1. Give the patient privacy to process their feelings
  2. Encourage the patient to think positively and focus on reasons to live
  3. Document the statement and discuss it at the next team meeting
  4. Implement one-to-one continuous observation and notify the provider immediately - the patient has a specific lethal plan

Answer: D — This patient has all three high-risk components: suicidal ideation (wants to die), a specific plan (take pills tonight), and access to lethal means (30 oxycodone at home). This is an imminent suicide risk requiring immediate one-to-one observation, provider notification, and means restriction (contact family to secure the pills).

Question 17: A nurse is caring for a patient on suicide precautions. Which action is MOST important?

  1. Assign the patient to a room at the end of the hallway for maximum privacy
  2. Conduct continuous or 15-minute safety checks as ordered and remove all potentially harmful items from the environment
  3. Allow the patient to keep personal belongings including belts and phone chargers in their room
  4. Keep the patient room door locked at all times to prevent elopement

Answer: B — Suicide precautions require removing all items that could be used for self-harm (belts, shoelaces, cords, sharps, plastic bags) and conducting safety checks at ordered intervals. The patient should be in a room near the nurse station for maximum visibility, not at the end of the hallway.

Question 18: A patient on a psychiatric unit becomes increasingly agitated and begins throwing objects. The nurse should FIRST:

  1. Leave the unit and wait for security to handle the situation
  2. Yell at the patient to stop the behavior immediately
  3. Approach calmly, maintain a safe distance, use a low steady voice, and offer the patient choices to de-escalate
  4. Physically restrain the patient immediately

Answer: C — De-escalation is always attempted before physical intervention. Maintain a safe distance, speak calmly and slowly, offer choices (Would you like to go to a quiet room?), avoid confrontational body language, and ensure other patients are safe. Restraints are the absolute last resort.

Question 19: A patient on suicide precautions suddenly becomes calm and cheerful after days of severe depression and tells the nurse they feel great. The nurse should:

  1. Recognize this as a potential warning sign that the patient has made a decision to act and INCREASE the level of observation
  2. Be relieved that the patient is improving and reduce the observation level
  3. Celebrate the improvement and encourage the patient to attend group activities
  4. Discharge the patient since their mood has clearly improved

Answer: A — A sudden unexplained mood shift from severe depression to calm cheerfulness is a classic warning sign - the patient may feel relieved after deciding to carry out a suicide plan. The nurse must increase observation, not decrease it, and notify the provider for reassessment.

Question 20: A patient with borderline personality disorder (BPD) tells one nurse they are wonderful and tells another nurse they are terrible and incompetent. This behavior is called:

  1. Displacement
  2. Regression
  3. Projection
  4. Splitting - viewing people as all good or all bad

Answer: D — Splitting is the hallmark defense mechanism in BPD where the patient divides people into idealized (all good) and devalued (all bad) categories with no middle ground. Staff must communicate consistently, maintain firm boundaries, and avoid being drawn into the splitting dynamic.

Question 21: A nurse is caring for a patient with antisocial personality disorder who is charming and attempts to manipulate staff to obtain special privileges. The BEST approach is:

  1. Avoid all interaction with the patient to prevent manipulation
  2. Maintain firm, consistent limits across all staff members and do not make exceptions regardless of the patient charm or arguments
  3. Allow some exceptions when the patient behaves well as positive reinforcement
  4. Grant the requests to maintain a positive therapeutic relationship

Answer: B — Patients with antisocial PD are skilled at manipulation, charm, and exploiting inconsistencies between staff members. The key nursing strategy is firm, consistent limit-setting across the entire team with no exceptions. Treatment plans and rules must be communicated clearly and enforced uniformly.

Question 22: A patient admitted for alcohol detoxification begins having visual hallucinations, severe tremors, tachycardia, and a seizure 72 hours after the last drink. The nurse recognizes this as:

  1. Wernicke encephalopathy from thiamine deficiency
  2. Normal anxiety associated with hospitalization
  3. A panic attack triggered by the hospital environment
  4. Delirium tremens (DTs) - a life-threatening alcohol withdrawal emergency

Answer: D — Delirium tremens typically occurs 48 to 96 hours after the last drink and is characterized by hallucinations (often visual - insects or animals), severe tremors, seizures, tachycardia, hypertension, and hyperthermia. DTs have a 5 to 15 percent mortality rate without treatment. Administer IV benzodiazepines and thiamine immediately.

Question 23: A patient in opioid withdrawal presents with dilated pupils, rhinorrhea, yawning, diaphoresis, and muscle aches. The nurse should understand that opioid withdrawal is:

  1. Life-threatening and requires immediate intubation
  2. Not real - patients exaggerate symptoms to obtain more opioids
  3. Best treated by immediately restarting the opioid of abuse
  4. Extremely uncomfortable but rarely life-threatening, unlike alcohol or benzodiazepine withdrawal

Answer: D — Opioid withdrawal is intensely uncomfortable but rarely fatal (unlike alcohol and benzodiazepine withdrawal which can cause fatal seizures). Symptoms are flu-like: dilated pupils, rhinorrhea, lacrimation, yawning, muscle aches, diarrhea, and insomnia. Treatment includes clonidine, NSAIDs, and medication-assisted treatment (methadone or buprenorphine).

Question 24: A nurse is using motivational interviewing with a patient who is ambivalent about quitting alcohol. Which statement BEST reflects this technique?

  1. You mentioned wanting to be healthier for your children. How do you think reducing your drinking might help with that goal?
  2. If you do not quit drinking, I cannot help you anymore.
  3. I am going to refer you to AA because that is the only way to get sober.
  4. You must stop drinking immediately or you will destroy your liver.

Answer: A — Motivational interviewing explores the patient own reasons for change without confrontation or coercion. The nurse reflects the patient stated values (children, health) and connects them to the behavior change. This builds intrinsic motivation rather than imposing external pressure.

Question 25: A nurse is assessing a patient using the CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol) scale. A score of 20 indicates:

  1. Severe withdrawal requiring aggressive IV benzodiazepine therapy and close monitoring
  2. No withdrawal symptoms present
  3. Minimal withdrawal symptoms requiring observation only
  4. Moderate withdrawal that may be managed with oral benzodiazepines

Answer: A — CIWA-Ar scores range from 0 to 67. Below 10 indicates mild withdrawal, 10 to 18 is moderate, and above 18 is severe requiring aggressive pharmacological treatment with benzodiazepines. A score of 20 falls in the severe category with significant risk for seizures and progression to delirium tremens.

How to master Mental Health Nursing

Learn disorders through patient presentation, not definitions

The NCLEX never defines a disorder for you. It gives you a patient — what they’re saying, what they’re doing, how they look — and asks you to respond appropriately. Study each disorder by its clinical picture: what does a manic patient actually say and do? What does a patient with schizophrenia actually look like on the ward? Thinking in patient scenarios rather than textbook definitions is what converts knowledge into correct answers.

Memorise psychiatric medication side effects that require intervention

Psychiatric meds are heavily tested not on their mechanism but on their dangerous side effects. The critical ones: lithium toxicity (tremor, diarrhoea, confusion — check levels), NMS from antipsychotics (hyperthermia, rigidity, altered LOC — stop drug immediately), EPS from typical antipsychotics (treat with benztropine), and serotonin syndrome from SSRIs (hyperthermia, agitation, clonus). Know the sign, know the drug, know what to do.

Know the priority in psychiatric emergencies: safety first, always

When a question involves a psychiatric patient who is a safety risk — suicidal, violent, or elopement risk — the correct first action is always to ensure safety. This means staying with the patient, removing environmental hazards, using de-escalation before restraints, and notifying the provider. The NCLEX never rewards restraining a patient as the first response unless there is immediate danger and all other options have failed.

Distinguish between disorders that present similarly

Several high-yield pairs are easily confused: mania vs. schizophrenia (both can include psychosis, but mania has elevated mood and grandiosity as the primary feature), OCD vs. GAD (OCD has intrusive thoughts and compulsions; GAD is pervasive free-floating worry), and depression vs. grief (depression is pathological; grief is a normal response that requires support, not medication first). Build a side-by-side comparison for each pair.

Retake until you score 85%+ consistently

Mental health questions become very predictable once you recognise the clinical patterns. Use each wrong answer to identify the specific condition or medication you missed, review that file in the cheat sheet below, and retake. Most students see a significant score jump after one targeted review session.

Quick Reference Condition Files

Each file below is one condition. Read across the row: what to recognise in the patient, the key medications and their critical side effects, the nursing priority, and the NCLEX trap that trips students up on that condition.

Each file has four zones: Recognise (how this condition presents), Key Medications (what’s prescribed and what to watch for), Nursing Priority (what the RN does first), and NCLEX Trap (the wrong answer that looks right).
Schizophrenia
Psychotic Disorder
Recognise
  • Positive: hallucinations (auditory most common), delusions, disorganised speech, thought insertion
  • Negative: flat affect, alogia, avolition, anhedonia, social withdrawal
  • Paranoid subtype: persecutory delusions — “They’re poisoning my food”
Key Medications
HaloperidolChlorpromazine
RisperidoneClozapine
  • EPS: dystonia, akathisia, pseudoparkinsonism → treat with benztropine
  • NMS: hyperthermia + rigidity + altered LOC → stop drug, notify provider STAT
  • Clozapine: weekly WBC — risk of agranulocytosis
Nursing Priority
  • Do not argue with or reinforce delusions — acknowledge the patient’s feelings without validating the false belief
  • For auditory hallucinations: “Are you hearing something I’m not hearing?”
  • Establish trust through consistent, calm interaction
  • Simple, concrete communication — avoid abstract language
NCLEX Trap
Telling a patient their delusion is false (“That’s not true — no one is poisoning you”) seems logical but is non-therapeutic. Correct: “I can see that feels very real and frightening to you.”
Bipolar Disorder — Manic Phase
Mood Disorder
Recognise
  • Elevated/expansive mood, grandiosity (“I’m going to cure cancer”)
  • Decreased need for sleep, pressured speech, flight of ideas
  • Impulsive behaviour: spending sprees, hypersexuality
  • Easily distracted, irritable if interrupted
Key Medications
LithiumValproateCarbamazepine
  • Lithium toxicity (level >1.5): tremor, diarrhoea, polyuria, confusion → hold, check level, notify provider
  • Maintain adequate sodium & fluid intake — dehydration raises lithium level
  • Therapeutic lithium level: 0.6–1.2 mEq/L
Nursing Priority
  • Provide low-stimulation environment — decrease sensory input
  • Ensure adequate nutrition (finger foods — patient won’t sit to eat)
  • Set firm, consistent limits on impulsive behaviour
  • Monitor for safety — impulsivity creates injury risk
NCLEX Trap
Students often choose a regular meal tray for a manic patient. Correct answer: finger foods and frequent snacks the patient can eat while moving — they cannot sit still for structured meals during acute mania.
Major Depressive Disorder
Mood Disorder
Recognise
  • Persistent depressed mood, anhedonia (loss of pleasure in all activities)
  • Sleep changes (insomnia or hypersomnia), appetite changes
  • Psychomotor retardation, fatigue, poor concentration
  • Feelings of worthlessness, recurrent thoughts of death
Key Medications
SSRIsSNRIsTCAsMAOIs
  • SSRIs: therapeutic effect takes 2–4 weeks — do not stop abruptly
  • Serotonin syndrome: hyperthermia, agitation, clonus, diaphoresis
  • TCAs: anticholinergic effects (dry mouth, urinary retention, constipation); lethal in overdose
  • MAOIs: strict tyramine diet — aged cheese, wine, cured meats cause hypertensive crisis
Nursing Priority
  • Safety first — assess for suicidal ideation at every contact (SAL: Suicidal ideation, Attempt history, Lethality of plan)
  • Remove environmental hazards from room
  • Spend time with patient — therapeutic presence
  • Encourage gradual activity — not forced cheerfulness
NCLEX Trap
When a depressed patient suddenly appears cheerful and calm, this is NOT a sign of improvement — it may indicate they have made a decision to attempt suicide and feel relief. Priority action: increase observation and assess for suicidal intent immediately.
Panic Disorder & GAD
Anxiety Disorder
Recognise
  • Panic attack: sudden intense fear, palpitations, diaphoresis, dyspnoea, sense of impending doom — peaks within 10 min
  • GAD: excessive uncontrollable worry about multiple areas (>6 months), muscle tension, fatigue, irritability
  • Both may present with physical symptoms mimicking cardiac or respiratory events
Key Medications
SSRIs (1st line)BuspironeBenzodiazepines
  • Buspirone: non-addictive, takes 2–4 weeks; do not use PRN
  • Benzodiazepines: short-term only — dependence risk, withdrawal seizures if stopped abruptly
  • Teach: slow diaphragmatic breathing, progressive relaxation
Nursing Priority
  • During panic attack: stay with patient; calm, low-stimulation environment
  • Speak in short, simple sentences; redirect breathing
  • Do not leave the patient alone — presence is therapeutic
  • After attack: explore triggers, teach relaxation techniques
NCLEX Trap
During an active panic attack, teaching the patient about anxiety management is non-therapeutic — they cannot process information while in acute panic. Teaching happens after the acute episode resolves.
Alcohol Withdrawal
Substance Use
Recognise — Timeline
  • 6–24 hrs: tremors, anxiety, diaphoresis, tachycardia, nausea
  • 24–48 hrs: seizures (highest risk window)
  • 48–72 hrs: delirium tremens (DTs) — confusion, hyperthermia, severe agitation, hallucinations
  • DTs are life-threatening — mortality if untreated
Key Medications
LorazepamChlordiazepoxideThiamine
  • Benzodiazepines are the treatment of choice — titrated via CIWA-Ar scale
  • Thiamine (Vitamin B1) before glucose — prevents Wernicke’s encephalopathy
  • Seizure precautions; IV access; padded side rails
Nursing Priority
  • Monitor vitals frequently — tachycardia and hypertension are early warning signs
  • Quiet, calm, low-stimulation environment
  • Seizure precautions from admission
  • Use CIWA-Ar scale to guide benzodiazepine dosing
NCLEX Trap
Always give thiamine BEFORE administering glucose/dextrose in a patient with chronic alcohol use. Giving glucose first can precipitate Wernicke’s encephalopathy (ophthalmoplegia, ataxia, confusion).
PTSD & OCD
Anxiety-Related
Recognise
  • PTSD: flashbacks, hypervigilance, avoidance of triggers, nightmares, emotional numbing following traumatic event
  • OCD: intrusive unwanted thoughts (obsessions) + repetitive behaviours to neutralise them (compulsions)
  • OCD ego-dystonic — patient knows the compulsions are irrational but cannot stop
Key Medications
SSRIs (1st line)Clomipramine (OCD)Prazosin (PTSD nightmares)
  • Therapy: CBT and exposure and response prevention (ERP) for OCD
  • EMDR (Eye Movement Desensitisation and Reprocessing) for PTSD
Nursing Priority
  • PTSD: establish safety; never touch without warning; explain all procedures; avoid unexpected sensory stimuli
  • OCD: allow rituals if not physically harmful — interrupting compulsions causes extreme anxiety
  • Do not reinforce or escalate rituals
NCLEX Trap
For OCD, forcibly preventing or interrupting a ritual is not therapeutic and causes severe anxiety. Correct approach: allow the ritual, schedule time for it, and gradually work toward reduction in therapy — never abrupt interruption by the nurse.

Frequently asked questions

How is Mental Health Nursing tested on the NCLEX-RN?
Mental Health Nursing questions appear as scenario-based items where you’re given a patient’s behaviour, statements, or clinical findings and asked to identify the appropriate nursing response, select the correct medication-related action, or prioritise among competing interventions. The category overlaps significantly with Psychosocial Integrity and Safe & Effective Care, so strong mental health knowledge improves your score across multiple sections.
What’s the most dangerous psychiatric medication side effect to know?
Neuroleptic Malignant Syndrome (NMS) is the most immediately life-threatening. It occurs with antipsychotic medications and presents with hyperthermia, severe muscle rigidity, altered consciousness, and autonomic instability. The nurse’s priority action is to stop the antipsychotic immediately and notify the provider. Contrast this with EPS (extrapyramidal symptoms), which is less urgent and treated with benztropine (Cogentin).
What are positive vs. negative symptoms of schizophrenia?
Positive symptoms are additions to normal experience: hallucinations (hearing voices, most commonly auditory), delusions, disorganised speech, and bizarre behaviour. Negative symptoms are absences of normal function: flat affect, alogia (poverty of speech), avolition (lack of motivation), anhedonia (inability to feel pleasure), and social withdrawal. Negative symptoms are harder to treat and respond less well to typical antipsychotics.
When is a depressed patient at highest risk for suicide?
Two high-risk windows: first, when the patient shows a sudden improvement in mood and energy after a period of deep depression — this may mean they’ve made a decision to attempt suicide and feel relief. Second, in the early weeks of antidepressant treatment when energy returns before mood improves, giving the patient enough energy to act on suicidal ideation. Both periods require heightened monitoring and direct safety assessment.
What is the CIWA-Ar scale and when is it used?
CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol) is a standardised tool used to assess the severity of alcohol withdrawal symptoms and guide benzodiazepine dosing. It scores 10 items including tremor, diaphoresis, anxiety, agitation, and perceptual disturbances. Higher scores indicate more severe withdrawal and require higher benzodiazepine doses. It should be assessed frequently (every 1–4 hours) during the first 48–72 hours of withdrawal.
Can I take this quiz more than once?
Yes, unlimited retakes with no signup required. For Mental Health specifically, review the condition file for any disorder where you lost points, then retake. The clinical pattern for each disorder is consistent — once you recognise it, the questions become very predictable.
