• Advanced Practice Skills and Psychiatric Assessment
• Diagnosis and Treatment of Major Psychiatric Disorders

INTRODUCTION
This comprehensive assessment is designed to evaluate mastery of the knowledge
and skills required for the APEA Psychiatric-Mental Health Nurse Practitioner
(PMHNP) certification examination. It assesses competency across eight core
domains, including neurobiology, advanced practice skills, diagnosis and
treatment, psychopharmacology, psychotherapy, ethics and legal principles,
health promotion, and professional role. The examination employs multiple-
choice and scenario-based questions to simulate real-world clinical decision-
making challenges faced by psychiatric-mental health nurse practitioners across
the lifespan. Emphasis is placed on critical thinking, evidence-based practice, and
the ability to apply advanced psychiatric assessment and treatment principles in
,complex professional environments. This test bank prepares candidates for the
demands of the APEA PMHNP certification examination.
SECTION ONE: QUESTIONS 1–400
Question 1
A PMHNP is reviewing the neurobiology of major depressive disorder with a
preceptor. The discussion centers on monoamine hypotheses and neuroplasticity.
Which statement best reflects current understanding of the role of BDNF in
depression pathophysiology?
A. BDNF is relevant only to anxiety disorders and has no role in mood regulation
B. Antidepressants act solely by increasing synaptic monoamines with no effect
on neurotrophic factors
C. Reduced BDNF signaling in the hippocampus and prefrontal cortex is associated
with impaired neuroplasticity and is a target of several antidepressant
mechanisms
D. BDNF levels are consistently elevated in untreated major depression and must
be suppressed for recovery
Correct answer: C
RATIONALE: Contemporary models link stress-related reductions in BDNF to
impaired neuroplasticity in key mood-regulating circuits; many effective
treatments restore BDNF signaling. Option A is incorrect; BDNF plays a critical role
in mood disorders, not just anxiety. Option B is incorrect; antidepressants also
affect neurotrophic factors. Option D is incorrect; BDNF levels are typically
reduced, not elevated, in untreated depression. Understanding BDNF's role is
essential for understanding the mechanism of action of antidepressants and the
pathophysiology of depression.
Question 2
,During a psychopharmacology seminar a student asks why dopamine D2 receptor
blockade is central to the efficacy of first-generation antipsychotics. Which
explanation is most accurate?
A. All therapeutic effects of antipsychotics are mediated exclusively through GABA
receptors
B. Dopamine blockade produces antidepressant rather than antipsychotic effects
C. Mesolimbic D2 blockade is associated with reduction of positive psychotic
symptoms, while nigrostriatal blockade contributes to extrapyramidal side effects
D. D2 blockade is irrelevant to antipsychotic action and only serotonin receptors
matter
Correct answer: C
RATIONALE: The classic dopamine hypothesis and clinical pharmacology of
typical antipsychotics center on D2 occupancy in mesolimbic versus nigrostriatal
pathways. Option A is incorrect; antipsychotics primarily act on dopamine, not
GABA receptors. Option B is incorrect; D2 blockade produces antipsychotic, not
antidepressant, effects. Option D is incorrect; D2 blockade is central to
antipsychotic action. Understanding the distinct pathways affected by D2
blockade explains both the therapeutic effects and the side effects of first-
generation antipsychotics.
Question 3
A patient with new-onset psychosis is found to have markedly elevated serum
calcium and a parathyroid adenoma. Which principle of psychiatric differential
diagnosis does this case illustrate?
A. Only primary psychiatric disorders can cause psychosis
B. Parathyroid disease is irrelevant to psychiatric assessment
C. Medical and metabolic conditions can produce secondary psychiatric symptoms
and must be excluded before attributing findings solely to a primary psychiatric
disorder
D. Hypercalcemia never affects mental status
, Correct answer: C
RATIONALE: PMHNP must systematically evaluate medical contributors to
psychiatric presentations; hypercalcemia is a classic reversible cause of psychiatric
symptoms. Option A is incorrect; medical conditions can cause psychosis. Option
B is incorrect; parathyroid disease can affect mental status. Option D is incorrect;
hypercalcemia commonly causes confusion, depression, and psychosis. This case
illustrates the importance of a thorough medical workup in new-onset psychiatric
symptoms.
Question 4
An older adult develops acute confusion, fluctuating attention, and visual
hallucinations over 48 hours in the setting of a urinary tract infection. Which
diagnosis is most consistent with the time course and features?
A. Major depressive disorder with psychotic features
B. Chronic neurocognitive disorder without acute change
C. Delirium secondary to medical illness
D. Late-onset schizophrenia
Correct answer: C
RATIONALE: Delirium is characterized by acute onset, fluctuating course, and
impaired attention, often precipitated by infection or other medical insults.
Option A is incorrect; major depressive disorder does not typically present with
acute confusion. Option B is incorrect; chronic neurocognitive disorder has a
gradual onset. Option D is incorrect; late-onset schizophrenia is rare and does not
typically present with fluctuating attention. Recognizing delirium is critical
because it requires immediate medical intervention.
