ABSTRACT
This study document brings together 100 carefully worded exam questions drawn from NSG 3450
Mental Health Exam Questions and Correct Answers with Rationales New 2026-2027 Update
Galen College of Nursing, with the strongest emphasis placed on Apply DSM-5-TR criteria to
complex psychiatric presentations, Evaluate psychopharmacologic regimens for efficacy, safety,
and interactions and Prioritize nursing interventions in acute psychiatric and crisis situations. 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 CRITERIA TO COMPLEX PSYCHIATRIC PRESENTATIONS
A patient with schizophrenia is prescribed clozapine. Which laboratory finding
would necessitate immediate intervention?
A. Absolute neutrophil count of 1,200/µL CORRECT
B. Fasting blood glucose of 110 mg/dL
C. Total cholesterol of 210 mg/dL
D. Serum prolactin level of 25 ng/mL
RATIONALE: Clozapine can cause severe neutropenia; an ANC below 1,500/µL requires
immediate discontinuation and monitoring per FDA guidelines. The other values are mild and do
not require urgent action.
Q2 APPLY DSM-5-TR CRITERIA TO COMPLEX PSYCHIATRIC PRESENTATIONS
A patient exhibits sudden onset of severe anxiety, palpitations, and fear of dying,
lasting 20 minutes. Which neurotransmitter system is most implicated in this
presentation?
A. Dopaminergic
B. GABAergic
C. Serotonergic
D. Noradrenergic CORRECT
RATIONALE: Panic attacks are primarily associated with noradrenergic hyperactivity in the locus
coeruleus. GABAergic deficits contribute to anxiety but are not the primary acute mechanism.
Dopamine and serotonin are more linked to psychosis and mood disorders, respectively.

,Q3 APPLY DSM-5-TR CRITERIA TO COMPLEX PSYCHIATRIC PRESENTATIONS
A patient on lithium reports nausea, coarse hand tremor, and confusion. Which
action should the nurse take first?
A. Administer the next scheduled lithium dose
B. Hold the lithium and obtain a serum lithium level CORRECT
C. Encourage increased fluid intake
D. Administer an antiemetic and reassess in 1 hour
RATIONALE: These symptoms suggest lithium toxicity; the nurse must hold the drug and check
the level immediately. Administering the next dose or only treating symptoms could worsen
toxicity. Increased fluids may be appropriate later but not before evaluation.
Q4 APPLY DSM-5-TR CRITERIA TO COMPLEX PSYCHIATRIC PRESENTATIONS
Which statement by a patient indicates a need for further teaching about selective
serotonin reuptake inhibitors (SSRIs)?
A. I should take this medication in the morning to avoid insomnia.
B. I may experience sexual dysfunction while on this medication.
C. I can stop the medication abruptly if I feel better. CORRECT
D. It may take several weeks before I notice improvement.
RATIONALE: SSRIs should not be stopped abruptly due to discontinuation syndrome; tapering is
required. The other statements are accurate: morning dosing reduces insomnia, sexual
dysfunction is common, and therapeutic effects take weeks.

, Q5 APPLY DSM-5-TR CRITERIA TO COMPLEX PSYCHIATRIC PRESENTATIONS
A patient with borderline personality disorder engages in self-harm. Which
nursing intervention is most appropriate initially?
A. Set strict limits on manipulative behavior
B. Establish a therapeutic relationship with consistent boundaries CORRECT
C. Administer PRN antipsychotic medication
D. Refer to dialectical behavior therapy immediately
RATIONALE: The priority is building a trusting therapeutic relationship with clear, consistent
boundaries to promote safety. Limit-setting and PRN medication may be needed later, but the
initial focus is engagement. Immediate DBT referral is not the first step in acute care.
Q6 APPLY DSM-5-TR CRITERIA TO COMPLEX PSYCHIATRIC PRESENTATIONS
A patient is admitted with acute alcohol intoxication. Which assessment finding
indicates impending delirium tremens?
A. Blood alcohol level of 0.25%
B. Heart rate of 110 bpm and diaphoresis CORRECT
C. Respiratory rate of 12/min
D. Serum potassium of 3.5 mEq/L
RATIONALE: Autonomic hyperactivity (tachycardia, diaphoresis) signals impending delirium
tremens, a medical emergency. Blood alcohol level alone does not predict DTs. Normal
respiratory rate and potassium are not indicative.
