NSG 527 Final Exam Nursing Comprehensive Advanced
Practice Psych 2026/2027 - Questions and Answers 100%
Verified Detailed Rationales - Pass Guaranteed - A+ Graded
This comprehensive final examination assesses the advanced practice psychiatric-mental health nurse practitioner
(PMHNP) student's mastery of psychopharmacologic management, evidence-based psychotherapeutic modalities,
advanced diagnostic reasoning, mental health assessment, patient education, ethical-legal decision-making, and
professional role development. Items require synthesis of DSM-5-TR criteria, current clinical guidelines, and
PMHNP competencies to manage complex psychiatric presentations across the lifespan. It contains 98
multiple-choice questions, each with four distractors and a fully worked rationale that explains why the keyed
answer is correct. Questions are organized into clearly labelled sections that mirror the major content areas of
the course. Targeted learning outcomes include: Synthesize advanced psychiatric assessment data to formulate
differential diagnoses using DSM-5-TR and ICD-11 criteria.; Design safe, evidence-based psychopharmacologic
regimens that account for pharmacogenomics, drug interactions, and adverse-effect profiles.; Select and adapt
psychotherapeutic interventions based on patient presentation, developmental stage, and comorbidity.; Apply
ethical-legal principles and PMHNP scope-of-practice standards to complex clinical and professional scenarios..
Every item has been reviewed for clinical accuracy, current guidelines, and clarity so that students can study with
confidence and self-correct as they work through the bank. Use it as a high-yield review immediately before the
exam, or as a structured practice tool during the unit - the rationales double as concise teaching notes. The
Section 1: General (Questions 1-98)
1 Which CYP450 interaction most increases clozapine toxicity risk when
fluvoxamine is co-prescribed?
A) Fluvoxamine induces CYP1A2, decreasing clozapine levels
B) Fluvoxamine inhibits CYP1A2, raising clozapine levels
C) Fluvoxamine inhibits CYP3A4, raising clozapine levels
D) Fluvoxamine induces CYP3A4, decreasing clozapine levels
Answer: B
Rationale: Fluvoxamine is a potent CYP1A2 inhibitor; clozapine is primarily
metabolized by CYP1A2, so inhibition markedly elevates clozapine levels and risks
agranulocytosis, myocarditis, and seizures. The other options misstate the enzyme or
direction of effect.
2 Which finding best differentiates PTSD from acute stress disorder according to
DSM-5-TR?
A) Presence of intrusive memories
B) Duration of symptoms exceeding one month
C) Avoidance of trauma-related stimuli
D) Hypervigilance and sleep disturbance
Answer: B
,Rationale: DSM-5-TR distinguishes PTSD from acute stress disorder primarily by
symptom duration: acute stress disorder lasts 3 days to 1 month, while PTSD
requires symptoms persisting beyond 1 month. Intrusions, avoidance, and
hypervigilance occur in both, so they do not differentiate.
3 A patient on SSRIs reports improved mood but persistent anhedonia. Which
augmentation has strongest evidence?
A) Adding aripiprazole
B) Adding buspirone
C) Adding mirtazapine
D) Adding hydroxyzine
Answer: A
Rationale: Aripiprazole has the most robust evidence among atypical antipsychotics
for augmenting SSRIs in treatment-resistant depression with residual anhedonia, per
STAR*D and subsequent trials. Buspirone, mirtazapine, and hydroxyzine lack
comparable efficacy for this specific residual symptom.
4 Which therapy component is essential in dialectical behavior therapy for
borderline personality disorder?
A) Systematic exposure to trauma memories
B) Cognitive restructuring of core beliefs
C) Distress tolerance and mindfulness skills
D) Free association and dream analysis
Answer: C
Rationale: DBT uniquely integrates mindfulness, distress tolerance, emotion
regulation, and interpersonal effectiveness skills to reduce self-harm and improve
functioning in borderline personality disorder. Exposure, cognitive restructuring,
and psychodynamic techniques are not core DBT modules.
5 Which assessment tool is most appropriate for detecting delirium in a hospitalized
patient with dementia?
A) MMSE
B) MoCA
C) CAM
D) GDS
Answer: C
Rationale: The Confusion Assessment Method (CAM) is validated for rapid delirium
detection and distinguishes delirium from dementia by assessing acute onset,
,inattention, disorganized thinking, and altered consciousness. MMSE and MoCA
measure cognition but do not diagnose delirium; GDS screens depression.
6 Which action best demonstrates PMHNP ethical fidelity when a patient refuses a
recommended antipsychotic?
A) Administer the medication involuntarily
B) Document refusal and explore reasons
C) Discharge the patient from care
D) Consult the family to override refusal
Answer: B
Rationale: Ethical fidelity requires respecting patient autonomy, documenting the
informed refusal, and exploring underlying concerns to maintain therapeutic
alliance. Involuntary administration, discharge, or family override without legal
justification violates ethical and legal standards.
7 Which statement about long-acting injectable antipsychotics is most accurate for
adherence?
A) They eliminate need for oral antipsychotics entirely
B) They improve adherence but require oral tolerability trial
C) They have no role in first-episode psychosis
D) They are contraindicated in substance use disorders
Answer: B
Rationale: LAIs improve adherence and reduce relapse, but current guidelines
recommend establishing oral tolerability before initiating to avoid adverse reactions.
They do not eliminate all oral use, are used in first-episode psychosis, and are not
contraindicated in substance use disorders.
8 Which finding most suggests serotonin syndrome rather than neuroleptic
malignant syndrome?
A) Lead-pipe rigidity
B) Hyperreflexia and clonus
C) Marked elevated creatine kinase
D) Bradyreflexia with hyperthermia
Answer: B
Rationale: Serotonin syndrome classically presents with neuromuscular
hyperexcitability-hyperreflexia and clonus-especially in lower extremities, whereas
NMS features lead-pipe rigidity, bradyreflexia, and marked CK elevation. The other
options describe NMS or nonspecific findings.
, 9 Which factor most predicts antidepressant response in major depressive disorder
per STAR*D?
A) Early improvement at 2 weeks
B) Baseline severity score
C) Duration of current episode
D) Family history of bipolar disorder
Answer: A
Rationale: STAR*D and subsequent analyses show early symptomatic improvement
within 2 weeks strongly predicts eventual response and remission. Baseline severity,
episode duration, and family history of bipolar disorder influence treatment selection
but are weaker predictors of acute response.
10 Which legal principle allows emergency involuntary psychiatric hold without
court order?
A) Parens patriae
B) Respondeat superior
C) Police power
D) Informed consent
Answer: C
Rationale: Police power permits the state to detain individuals who pose an imminent
danger to self or others without prior court order, typically via emergency hold
statutes. Parens patriae protects those unable to care for themselves but usually
requires judicial process; respondeat superior and informed consent are unrelated.
11 Which finding best distinguishes serotonin syndrome from neuroleptic malignant
syndrome?
A) Lead-pipe rigidity with hyporeflexia and bradycardia
B) Clonus with hyperreflexia and dilated pupils
C) Rhabdomyolysis with markedly elevated creatine kinase
D) Hyperthermia with autonomic instability and leukocytosis
Answer: B
Rationale: Serotonin syndrome features neuromuscular excitability—clonus,
hyperreflexia, and mydriasis-due to excess serotonergic activity. NMS instead
shows lead-pipe rigidity, hyporeflexia, bradycardia, and prominent CK elevation;
rhabdomyolysis and leukocytosis are more characteristic of NMS.
12 A patient on lithium develops coarse tremor, ataxia, and confusion. Which action
is priority?
