Final Review Mental and Behavioral Health Nursing Questions, Correct Answers, and Rationales
New Update 2026-2027, with the strongest emphasis placed on Apply DSM-5-TR diagnostic
criteria and differential reasoning to complex psychiatric presentations, Prioritize safe,
evidence-based nursing interventions across acute, crisis, and community mental health settings,
Integrate psychopharmacologic, legal-ethical and and therapeutic communication principles into
clinical judgment. Every item follows the wording style and level of reasoning you meet in the real
paper, and each one is paired with a clear rationale so the correct choice is never a guess. Work
through the set at your own pace, mark the questions that slow you down, then come back to them
until the reasoning feels automatic. Learners who revise this way walk into the exam room
recognising the pattern behind the questions instead of meeting them for the first time. Keep going
- steady, honest practice is what turns a difficult paper into a comfortable pass.

,Q1 APPLY DSM-5-TR DIAGNOSTIC CRITERIA AND DIFFERENTIAL REASONING TO COMPLEX
PSYCHIATRIC PRESENTATIONS
A client receiving clozapine for treatment-resistant schizophrenia presents with
fever, tachycardia, and a diffuse erythematous rash. Which laboratory finding
would most specifically confirm the priority life-threatening adverse effect?
A. Absolute neutrophil count of 450/mm³ CORRECT
B. Serum clozapine level of 600 ng/mL
C. Creatine kinase of 1,200 U/L
D. Eosinophil count of 8%
RATIONALE: Fever, tachycardia, and rash suggest neutropenic sepsis from clozapine-induced
agranulocytosis; an ANC <500/mm³ confirms severe neutropenia. Elevated CK indicates
neuroleptic malignant syndrome, not agranulocytosis. Clozapine levels and eosinophilia are
nonspecific and do not confirm the priority risk.
Q2 APPLY DSM-5-TR DIAGNOSTIC CRITERIA AND DIFFERENTIAL REASONING TO COMPLEX
PSYCHIATRIC PRESENTATIONS
Which nursing action best reflects the ethical principle of veracity when a client
with terminal illness and depression asks whether their antidepressant 'will make
everything better'?
A. Reassure the client that medications always improve mood within days.
B. Provide honest information about expected benefits, timeline, and limitations of
pharmacotherapy. CORRECT
C. Defer the question to the provider to avoid causing distress.
D. Offer a comforting statement that everything will work out.
RATIONALE: Veracity obligates truthful communication; the nurse must accurately explain
realistic expectations, onset, and limits of antidepressants. Reassurance with false certainty
violates veracity, and deferral or platitudes avoid the ethical duty rather than fulfill it.

,Q3 APPLY DSM-5-TR DIAGNOSTIC CRITERIA AND DIFFERENTIAL REASONING TO COMPLEX
PSYCHIATRIC PRESENTATIONS
During a therapeutic communication session, a client with borderline personality
disorder says, 'You're the only nurse who understands me; the others are
incompetent.' Which response best demonstrates maintaining professional
boundaries?
A. 'I appreciate that, and I feel the same about you.'
B. 'That's a strong feeling; let's explore what makes it hard to trust the team.' CORRECT
C. 'You shouldn't say that about your other nurses.'
D. 'I'll request to be your only assigned nurse.'
RATIONALE: Reflecting the client's feeling and exploring trust dynamics maintains boundaries
while addressing splitting. Agreeing, scolding, or arranging exclusive assignment reinforces
splitting or boundary violation and undermines the therapeutic alliance.
Q4 APPLY DSM-5-TR DIAGNOSTIC CRITERIA AND DIFFERENTIAL REASONING TO COMPLEX
PSYCHIATRIC PRESENTATIONS
A client with alcohol use disorder is admitted with tremors, diaphoresis, and HR
122. Which prescription should the nurse question as contraindicated during
acute withdrawal management?
A. Thiamine 100 mg IV
B. Lorazepam 2 mg IV PRN CIWA >15
C. Chlordiazepoxide 25 mg PO QID
D. Disulfiram 500 mg PO daily CORRECT
RATIONALE: Disulfiram is contraindicated during acute withdrawal and while any alcohol may
remain in the body due to risk of severe acetaldehyde reaction; it is initiated only after
detoxification and abstinence are established. Thiamine, lorazepam, and chlordiazepoxide are
appropriate for withdrawal management.

, Q5 APPLY DSM-5-TR DIAGNOSTIC CRITERIA AND DIFFERENTIAL REASONING TO COMPLEX
PSYCHIATRIC PRESENTATIONS
A client with major depressive disorder reports no improvement after 3 weeks of
sertraline 50 mg daily. Which action best reflects current evidence-based practice?
A. Immediately discontinue sertraline and start a monoamine oxidase inhibitor.
B. Continue the current dose and reassess at 6-8 weeks before any change.
C. Collaborate with the provider to consider dose optimization or augmentation. CORRECT
D. Add St. John's wort to enhance antidepressant effect.
RATIONALE: Partial or no response at 3 weeks warrants reassessment and possible dose
increase or augmentation, not premature discontinuation. Waiting until 6-8 weeks without
adjustment may delay effective treatment, and adding St. John's wort risks serotonin syndrome.
Q6 APPLY DSM-5-TR DIAGNOSTIC CRITERIA AND DIFFERENTIAL REASONING TO COMPLEX
PSYCHIATRIC PRESENTATIONS
Which assessment finding most strongly indicates that a client with anorexia
nervosa requires immediate medical stabilization rather than outpatient care?
A. Body mass index of 17.2 kg/m²
B. Serum potassium of 2.8 mEq/L with QT prolongation CORRECT
C. Reported fear of gaining weight
D. Lanugo hair on the forearms
RATIONALE: Severe hypokalemia with QT prolongation signals dangerous cardiac instability and
necessitates acute medical stabilization. BMI 17.2, fear of weight gain, and lanugo are
concerning but do not independently mandate immediate inpatient medical stabilization as
strongly as life-threatening electrolyte and ECG changes.
