NCLEX Mental Health & Substance Use questions

In short

The PrepScore bank has 77 Mental Health & Substance Use questions, each with a rationale and two tags: the Client Needs category from the test plan and the clinical judgment step it tests. In this topic the items lean on Generate solutions and Take action, which is worth knowing before you practise it. Three worked samples are below, answers behind a reveal.

Suicide risk escalation, mania, psychosis, alcohol and opioid withdrawal, NMS, serotonin syndrome, refeeding — what NCLEX tests beyond therapeutic communication.

Three worked questions

Q1. A 45-year-old male admitted for elective surgery yesterday reports last drink 36 hours ago. He has tremors, HR 118, BP 158/98, anxiety, and diaphoresis. CIWA-Ar score is 18. The nurse identifies alcohol withdrawal. Which intervention is the PRIORITY?

  • A. Discharge the patient home and instruct to return to alcohol use if withdrawal symptoms worsen
  • B. Administer benzodiazepine per CIWA protocol (lorazepam or chlordiazepoxide) + continuous monitoring + IV thiamine before glucose + IV hydration + monitor for progression to DTs
  • C. Encourage the patient to drink water only and reassure that the symptoms will resolve spontaneously
  • D. Apply physical restraints without pharmacologic management of the alcohol withdrawal symptoms or syndrome
Show answer and rationale

Answer: Administer benzodiazepine per CIWA protocol (lorazepam or chlordiazepoxide) + continuous monitoring + IV thiamine before glucose + IV hydration + monitor for progression to DTs

CIWA ≥ 15 = moderate-to-severe alcohol withdrawal. Symptom-triggered benzo (lorazepam or chlordiazepoxide) + monitoring + thiamine before glucose + hydration + watch for DTs. Discharge, water alone, or restraints are wrong.

Q2. A 32-year-old male with opioid use disorder asks the nurse about treatment options. He has been using heroin daily × 3 years and is motivated for recovery. The nurse provides evidence-based options. Which approach is APPROPRIATE for managing opioid use disorder?

  • A. Cold-turkey detoxification alone without medication-assisted treatment or counseling support during recovery
  • B. Medication-assisted treatment (MAT): methadone, buprenorphine/naloxone, or naltrexone + behavioral counseling + harm reduction (naloxone home rescue kit) + community support
  • C. Punishment and judgment with confrontational interview style to motivate the patient toward immediate abstinence
  • D. Strict abstinence enforcement only without medication or counseling support for the patient's recovery
Show answer and rationale

Answer: Medication-assisted treatment (MAT): methadone, buprenorphine/naloxone, or naltrexone + behavioral counseling + harm reduction (naloxone home rescue kit) + community support

OUD treatment: MAT (methadone, buprenorphine, naltrexone) + behavioral counseling + harm reduction (naloxone) + community support — proven reduced mortality and recidivism. Cold-turkey, punishment, or abstinence-only are inadequate.

Q3. A 50-year-old male with chronic alcohol use disorder is admitted for alcohol detoxification. The medical team prescribes IV thiamine to prevent Wernicke encephalopathy. The nurse administers Wernicke prevention. Which intervention is APPROPRIATE for Wernicke prevention?

  • A. Administer glucose-containing IV fluid first before any thiamine administration in the detoxifying patient
  • B. Administer thiamine BEFORE or WITH glucose-containing fluids (glucose without thiamine first can PRECIPITATE Wernicke encephalopathy)
  • C. Administer vitamin C only without thiamine or other B vitamins for Wernicke prevention in the patient
  • D. Administer naloxone instead of thiamine for Wernicke encephalopathy prevention in the detoxifying patient
Show answer and rationale

Answer: Administer thiamine BEFORE or WITH glucose-containing fluids (glucose without thiamine first can PRECIPITATE Wernicke encephalopathy)

Thiamine MUST be administered BEFORE or with glucose-containing fluids in chronic alcohol users. Glucose first depletes already-low thiamine and precipitates Wernicke encephalopathy. Vitamin C or naloxone are not Wernicke prevention.

The rules that decide these questions

From the pack's rule cards — the reasoning shortcuts a wrong answer usually means you were missing.

Mania management = LOW stim + finger foods + mood stabilizer + PRN atypical

Manic clients worsen with stimulation. Provide low-stim environment, finger foods + frequent fluids, brief firm limit-setting. Restart mood stabilizer (lithium with labs) + atypical antipsychotic + PRN benzo for agitation/sleep. Avoid groups, debate, and high-stim activities. Protect from impulsive financial/social decisions.

Alcohol withdrawal — front-load benzos, thiamine BEFORE glucose, DT window 48–96 h

Use symptom-triggered CIWA-based benzodiazepines (lorazepam) to control withdrawal. Always give thiamine 100 mg BEFORE any dextrose to prevent Wernicke's. Watch the trajectory: rising CIWA + autonomic + early visual hallucinations = pre-DT, treat now. Seizure precautions + sitter + low-stim; restraints are last resort.

Opioid OD — bag first, titrate naloxone to RR, observe long enough

Open airway and BVM ventilate before any large naloxone dose. Titrate IV naloxone in 0.04–0.4 mg increments targeting RR ≥ 12 and oxygenation — NOT consciousness. Big bolus = precipitated withdrawal (vomiting, aspiration, pulmonary edema). Naloxone half-life is shorter than many opioids — observe at least 4 hours after the last dose for re-sedation.

Acute psychosis = environment + verbal de-escalation + oral first

Environmental safety first (remove objects, ensure clear paths). Verbal de-escalation: low calm voice, ≥ arm's length, one speaker, name the feeling, offer simple choices. Do NOT argue with delusions; reflect feelings. Offer oral antipsychotic ± benzo before IM. Restraints/seclusion are last resort.

Serotonin syndrome ≠ NMS — clonus vs rigidity, drug class differs

Serotonin syndrome: hyperreflexia + CLONUS (esp. lower limb) + autonomic + hyperthermia + recent SEROTONERGIC agent (SSRI, SNRI, tramadol, MAOI). NMS: LEAD-PIPE rigidity + autonomic + hyperthermia + altered mental status + recent ANTIPSYCHOTIC. Treatment differs — benzo + cyproheptadine for serotonin; benzo + dantrolene/bromocriptine for NMS. Do NOT use antipsychotics in serotonin syndrome.

NMS = stop the antipsychotic. Never more antipsychotic.

Neuroleptic malignant syndrome is caused by dopamine blockade. The drug IS the cause — STOP it. Hydrate aggressively to protect kidneys from rhabdomyolysis (elevated CK). Add dantrolene or bromocriptine per provider; cool actively. Watch for AKI, DIC, arrhythmias.
