Section 1: Foundations of PMHNP Practice (Biopsychosocial Model, Assessment,
Diagnosis, and Neurobiology)
Questions 1-15
Q1: A PMHNP is conducting an initial psychiatric evaluation of a 34-year-old patient presenting with persistent
sadness, anhedonia, and insomnia following the death of her spouse 4 months ago. Using the biopsychosocial model,
which combination of factors should the PMHNP prioritize FIRST in the comprehensive assessment?
A. Biological factors only, since grief is primarily a neurochemical imbalance
B. Biological, psychological, and social factors including family history of depression, coping mechanisms, and
social support network [CORRECT]
C. Social factors exclusively, focusing on the patient's interpersonal relationships and employment status
D. Psychological factors only, emphasizing cognitive distortions and maladaptive grief responses
Correct Answer: B
Rationale: The biopsychosocial model requires integration of biological (family history, neurochemistry), psychological (coping,
grief response), and social (support network, employment) factors. PMHNPs must assess all three domains to formulate a
comprehensive treatment plan. Focusing on only one domain violates the core tenet of the biopsychosocial approach taught in
the Walden NRNP 6675 curriculum.
Q2: According to the dopamine hypothesis of schizophrenia, which statement best describes the underlying
neurobiological mechanism?
A. Schizophrenia results from deficient dopaminergic activity in all brain regions
B. Schizophrenia results from excessive dopaminergic activity, particularly in the mesolimbic pathway
C. Schizophrenia is caused by a single genetic mutation affecting dopamine receptor density
D. Schizophrenia results from too much dopaminergic activity [CORRECT]
Correct Answer: D
Rationale: The dopamine hypothesis posits that schizophrenia results from too much dopaminergic activity. While the
mesolimbic pathway hyperactivity explains positive symptoms, the updated hypothesis recognizes that mesocortical pathway
hypodopaminergia contributes to negative and cognitive symptoms. Option B is partially correct but overly specific to the
mesolimbic pathway; the broad statement in D captures the classic hypothesis as taught in NRNP 6675.
Q3: A PMHNP is assessing a patient with suspected schizophrenia. The patient exhibits flat affect, social
withdrawal, and poverty of speech. These symptoms are MOST likely associated with dopamine dysfunction in
which pathway?
A. Mesolimbic pathway
B. Nigrostriatal pathway
C. Mesocortical pathway [CORRECT]
D. Tuberoinfundibular pathway
Correct Answer: C
Rationale: Negative symptoms of schizophrenia (flat affect, alogia, avolition) are associated with decreased dopaminergic
activity in the mesocortical pathway, which projects from the ventral tegmental area to the prefrontal cortex. The mesolimbic
pathway is associated with positive symptoms, the nigrostriatal with extrapyramidal symptoms, and the tuberoinfundibular with
prolactin regulation.
Q4: During a mental status examination, a PMHNP observes that a patient repeatedly checks the door locks and
expresses persistent fear that harm will come to their family despite being told the house is secure. The patient states,
"I know it doesn't make sense, but I can't stop." What is the MOST important clinical distinction the PMHNP should

make?
A. Whether the patient meets criteria for a psychotic disorder versus an anxiety disorder
B. Whether the patient has insight into the unreasonable nature of their obsessions and compulsions [CORRECT]
C. Whether the patient's symptoms are better explained by a substance-induced condition
D. Whether the patient has a family history of obsessive-compulsive disorder or schizophrenia
Correct Answer: B
Rationale: Patients with OCD typically retain insight, recognizing that their obsessions and compulsions are unreasonable or
excessive. Psychotic patients lack this insight and hold fixed, delusional beliefs. This distinction is fundamental to differential
diagnosis in the NRNP 6675 curriculum. The patient's statement "I know it doesn't make sense" demonstrates preserved insight
consistent with OCD rather than psychosis.
Q5: Which neurotransmitter system is the PRIMARY target of SSRIs in the treatment of depression and anxiety
disorders?
A. Dopamine reuptake inhibition via DAT blockade
B. Serotonin reuptake blockade via the serotonin transporter (SERT) [CORRECT]
C. Norepinephrine reuptake inhibition via NET blockade
D. GABA-A receptor potentiation
Correct Answer: B
Rationale: SSRIs (selective serotonin reuptake inhibitors) exert their therapeutic effect by blocking the serotonin transporter
(SERT), which increases serotonin availability in the synaptic cleft. DAT blockade describes the mechanism of stimulants or
bupropion, NET blockade describes SNRIs or TCAs, and GABA-A potentiation describes benzodiazepines.
Q6: A PMHNP is evaluating a 22-year-old college student who reports feeling "on edge" most days, difficulty
concentrating, muscle tension, and sleep disturbance for the past 8 months. Which neurotransmitter systems are
MOST implicated in this patient's presenting symptoms?
A. Dopamine and norepinephrine only
B. GABA, serotonin, and norepinephrine [CORRECT]
C. Glutamate and dopamine only
D. Acetylcholine and histamine
Correct Answer: B
Rationale: Generalized anxiety disorder involves dysregulation of GABA (the primary inhibitory neurotransmitter, reduced
activity leads to anxiety), serotonin (low levels associated with anxiety and depression), and norepinephrine (hyperactivity
produces physical anxiety symptoms like muscle tension and autonomic arousal). This triad of neurotransmitter dysfunction is
central to the neurobiology of anxiety as taught in NRNP 6675.
Q7: A PMHNP is performing a comprehensive psychiatric assessment. Which component of the mental status
examination (MSE) evaluates the patient's thought content?
A. Appearance and behavior
B. Speech characteristics and rate
C. Delusions, obsessions, phobias, and suicidal ideation [CORRECT]
D. Orientation to person, place, and time
Correct Answer: C
Rationale: Thought content refers to what the patient is thinking about and includes delusions, obsessions, phobias, ideas of
reference, persecutory thoughts, and suicidal or homicidal ideation. Appearance and behavior are assessed through observation,
speech characteristics evaluate form and rate of speech, and orientation is a measure of cognitive function (sensorium).
