NR 607 Final Exam Chamberlain PMHNP - (2027) Actual
Questions & Answers (Guarantee Pass)
This final examination assesses graduate PMHNP students' mastery of advanced psychiatric health assessment,
differential diagnostic reasoning, and DSM-5-TR-aligned clinical decision-making. Items emphasize synthesis of
history, mental status findings, collateral data, and standardized instruments into defensible diagnostic
formulations and safety plans. It contains 95 multiple-choice questions, each with four distractors and a fully
worked rationale that explains why the keyed answer is correct. Content is organized into 12 focused sections:
Advanced Health Assessment and Diagnostic Reasoning, Psychopharmacology and Medication Management,
Psychotherapy and Therapeutic Modalities, Neurobiology and Psychiatric Pathophysiology, Mood Disorders
(Depressive and Bipolar), Anxiety, OCD, and Trauma-Related Disorders, Psychotic Disorders and Schizophrenia,
Substance Use and Addictive Disorders, Child, Adolescent, and Geriatric Mental Health, Ethical, Legal, and
Professional Practice Issues, Health Promotion, Prevention, and Patient Education, Care Transition and
Interprofessional Collaboration. Targeted learning outcomes include: Synthesize biopsychosocial history, mental
status examination, and collateral data to construct prioritized differential diagnoses consistent with DSM-5-TR
criteria.; Apply validated screening and assessment instruments with attention to psychometric properties, cutoff
selection, and cultural/linguistic validity.; Distinguish medical and substance-induced mimics of psychiatric
syndromes and determine appropriate diagnostic workup and referral.. Every item has been reviewed for clinical
Section 1: Advanced Health Assessment and Diagnostic Reasoning (Questions 1-8)
1 Which finding most strongly argues against a primary psychotic disorder in
new-onset psychosis?
A) Auditory hallucinations with preserved insight
B) Fluctuating cognition with visual hallucinations and parkinsonism
C) Premorbid schizotypal traits and gradual social decline
D) First-episode symptoms emerging at age 22
Answer: B
Rationale: Fluctuating cognition, visual hallucinations, and parkinsonism
constitute core features of Lewy body disease, a medical mimic of psychosis.
Preserved insight, schizotypal premorbid traits, and young adult onset are all
compatible with primary psychotic disorders and do not argue against them.
2 A patient's PHQ-9 score is 18 but the clinician suspects overreporting.
Which assessment approach best strengthens diagnostic validity?
A) Repeat the PHQ-9 one week later and average scores
B) Substitute the GAD-7 as a cross-check
C) Administer a symptom validity measure and structured clinical interview
D) Lower the diagnostic threshold to account for inflation
Answer: C
,Rationale: Symptom validity testing combined with a structured interview (e.g.,
SCID-5) provides the most rigorous method to detect overreporting and
confirm diagnosis. Repeating a self-report scale, substituting an anxiety
measure, or arbitrarily lowering thresholds does not address response bias.
3 Which mental status finding most specifically suggests delirium rather than
dementia?
A) Impaired recall after five-minute delay
B) Fluctuating attention with acute onset
C) Word-finding difficulty during conversation
D) Disorientation to year and month
Answer: B
Rationale: Acute onset with fluctuating attention is the defining feature of
delirium per DSM-5-TR. Delayed recall deficits, anomia, and temporal
disorientation occur in both delirium and dementia and are therefore less
specific.
4 Which pattern of findings best supports a differential of bipolar II over major
depressive disorder?
A) Recurrent depression with at least one hypomanic episode
B) Chronic low mood with intermittent irritability
C) Depression with psychotic features and psychomotor retardation
D) Seasonal depression responsive to light therapy
Answer: A
Rationale: Bipolar II requires at least one hypomanic episode plus major
depressive episodes, distinguishing it from MDD. Chronic low mood,
psychotic depression, and seasonal patterns do not establish hypomanic history
and thus do not differentiate bipolar II.
5 Which assessment element is most critical before attributing panic attacks to
panic disorder?
A) Family history of anxiety disorders
B) Recent caffeine and stimulant use history
C) Childhood separation anxiety history
D) Baseline personality assessment inventory
Answer: B
,Rationale: Stimulant and caffeine use can produce physiological panic-like
episodes and must be excluded before diagnosing panic disorder. Family
history, childhood anxiety, and personality inventories are relevant but not
exclusionary for substance/medication-induced anxiety.
6 Which collateral source provides the strongest validity for diagnosing a
neurocognitive disorder in a patient with limited insight?
A) Patient's self-rated cognitive complaints
B) Informant-based functional and cognitive decline report
C) Serial Mini-Mental State Examination scores alone
D) Personality inventory completed by the patient
Answer: B
Rationale: Informant report of functional and cognitive decline is essential
when insight is limited and is recommended by DSM-5-TR and NIA-AA
criteria. Self-report, a single cognitive screen, and personality inventories lack
sufficient validity for this determination.
7 Which diagnostic reasoning error is illustrated by anchoring on a patient's
prior bipolar diagnosis despite new manic-free depressive presentation?
A) Base-rate neglect
B) Confirmation bias
C) Availability heuristic
D) Premature closure
Answer: B
Rationale: Confirmation bias is the tendency to seek and interpret data
consistent with an existing hypothesis, such as a prior diagnosis. Base-rate
neglect, availability, and premature closure describe different reasoning
failures not exemplified by this scenario.
8 Which laboratory finding most strongly suggests a medical cause for new
depressive symptoms?
A) Elevated TSH with low free T4
B) Mildly elevated ALT
C) Low-normal ferritin
D) Borderline elevated CRP
Answer: A
, Rationale: Overt hypothyroidism (elevated TSH with low free T4) is a
well-established medical cause of depressive symptoms requiring correction
before attributing symptoms to MDD. Mild transaminase elevation,
low-normal ferritin, and borderline CRP are nonspecific and do not establish
causality.
Section 2: Psychopharmacology and Medication Management (Questions 9-16)
9 Which cytochrome P450 interaction most likely explains loss of clozapine
efficacy when carbamazepine is added?
A) Carbamazepine inhibits CYP1A2, raising clozapine levels
B) Carbamazepine induces CYP3A4 and CYP1A2, lowering clozapine levels
C) Carbamazepine inhibits CYP2D6, reducing clozapine clearance
D) Carbamazepine induces CYP2D6, increasing clozapine metabolism
Answer: B
Rationale: Carbamazepine is a potent inducer of CYP3A4 and CYP1A2;
clozapine is metabolized mainly by CYP1A2, so induction lowers clozapine
concentrations and can precipitate relapse. Option A reverses the effect
(inhibition would raise levels), and CYP2D6 is not the principal clozapine
pathway, making C and D incorrect.
10 A patient on MAOI develops hypertensive crisis after eating aged cheese.
Which mechanism best explains this?
A) Tyramine-induced norepinephrine release unopposed by MAO-A
inhibition
B) Serotonin syndrome from dietary tryptophan accumulation
C) Direct alpha-1 agonism by the MAOI metabolite
D) MAOI-mediated blockade of norepinephrine reuptake
Answer: A
Rationale: MAO-A inhibition prevents gut and hepatic breakdown of tyramine,
which then enters circulation and triggers massive norepinephrine release,
causing hypertensive crisis (the 'cheese reaction'). Serotonin syndrome (B) is
not the mechanism of tyramine hypertension, and MAOIs do not act as direct
alpha agonists (C) or norepinephrine reuptake blockers (D).
11 Which finding most strongly signals lithium toxicity requiring immediate
intervention despite a 'therapeutic' level?
