Based on the ANCC Psychiatric-Mental Health Nurse Practitioner board certification
blueprint, this practice exam covers all five domains: Scientific Foundation, Advanced
Practice Skills, Diagnosis & Treatment, Psychotherapy, and Ethical/Legal Principles.
Domain 1: Scientific Foundation
Question 1
Which neurotransmitter is primarily associated with the pathophysiology of
Parkinson's disease?
A) Serotonin
B) Dopamine
C) Norepinephrine
D) GABA
Correct Answer: B) Dopamine
Explanation: Parkinson's disease results from degeneration of dopaminergic neurons in the
substantia nigra pars compacta, leading to decreased dopamine in the basal ganglia. This
causes the classic motor symptoms of tremor, rigidity, bradykinesia, and postural
,instability. While other neurotransmitter systems are involved, dopamine deficiency is the
primary pathophysiology.
Question 2
A patient presents with auditory hallucinations, disorganized speech, and
avolition. Which brain region is most likely hyperactive in this patient?
A) Prefrontal cortex
B) Mesolimbic pathway
C) Cerebellum
D) Occipital lobe
Correct Answer: B) Mesolimbic pathway
Explanation: The mesolimbic pathway (ventral tegmental area to nucleus accumbens and
limbic structures) is hyperactive in schizophrenia, contributing to positive symptoms such
as hallucinations and delusions. The mesocortical pathway (to prefrontal cortex) is
hypoactive, contributing to negative symptoms such as avolition and affective flattening.
Question 3
According to Erikson's psychosocial stages, a 25-year-old who is struggling to
form close, meaningful relationships is experiencing difficulty with which stage?
A) Identity vs. Role Confusion
B) Intimacy vs. Isolation
C) Generativity vs. Stagnation
D) Integrity vs. Despair
Correct Answer: B) Intimacy vs. Isolation
*Explanation: Erikson's young adult stage (approximately ages 18-40) is Intimacy vs.
Isolation. Successful resolution involves forming close, committed relationships.
Difficulty at this stage leads to social isolation and loneliness. Identity formation
(previous stage) must be reasonably achieved before intimacy can be successfully
navigated.*
Question 4
,Which medication requires baseline and ongoing monitoring of absolute
neutrophil count (ANC) due to risk of agranulocytosis?
A) Risperidone
B) Quetiapine
C) Clozapine
D) Aripiprazole
Correct Answer: C) Clozapine
*Explanation: Clozapine carries a black box warning for severe neutropenia
(agranulocytosis) occurring in approximately 0.8% of patients. The REMS (Risk Evaluation
and Mitigation Strategy) program requires ANC monitoring weekly for the first 6
months, every 2 weeks for months 6-12, and monthly thereafter. ANC must be ≥1500/μL
to continue treatment.*
Question 5
A patient experiencing panic attacks reports feeling detached from their own body
during episodes. This symptom is called:
A) Derealization
B) Depersonalization
C) Dissociative amnesia
D) Fugue state
Correct Answer: B) Depersonalization
Explanation: Depersonalization is the sense of detachment from one's own body, thoughts,
or feelings (feeling like an outside observer). Derealization is the sense that the external
world is unreal or strange. Both can occur during panic attacks and are common in
anxiety and trauma-related disorders.
Question 6
The therapeutic index of lithium is narrow. A patient with lithium level of 1.8
mEq/L would most likely exhibit which symptom?
A) Fine hand tremor
B) Polyuria
, C) Ataxia and confusion
D) Weight gain
Correct Answer: C) Ataxia and confusion
*Explanation: Lithium toxicity occurs at levels >1.5 mEq/L. Early toxicity (1.5-2.0 mEq/L)
includes ataxia, coarse tremor, confusion, nausea, vomiting, and diarrhea. Severe toxicity
(>2.0 mEq/L) includes seizures, coma, and death. Fine tremor, polyuria, and weight gain
are common side effects at therapeutic levels (0.6-1.2 mEq/L).*
Question 7
Which of the following is a rate-limiting step in the synthesis of serotonin and
catecholamines?
A) Conversion of tryptophan to 5-HTP
B) Conversion of tyrosine to DOPA
C) Both A and B
D) Neither A nor B
Correct Answer: C) Both A and B
*Explanation: Tryptophan hydroxylase converts tryptophan to 5-HTP (precursor to
serotonin) and tyrosine hydroxylase converts tyrosine to DOPA (precursor to dopamine,
norepinephrine, epinephrine). Both enzymes are rate-limiting, meaning they are the
slowest step in the synthesis pathway and are targets for regulation.*
Question 8
A patient with borderline personality disorder uses splitting as a primary defense
mechanism. The PMHNP should recognize that splitting involves:
A) Converting psychological distress into physical symptoms
B) Viewing people and situations as all good or all bad
C) Attributing one's own unacceptable thoughts to others
D) Returning to an earlier developmental stage under stress
Correct Answer: B) Viewing people and situations as all good or all bad
Explanation: Splitting is a primitive defense mechanism common in borderline personality
disorder where the individual categorizes experiences, people, or self as either entirely
