SECTION 1: PSYCHIATRIC ASSESSMENT & DIAGNOSIS
(Questions 1-20)
1. A 45-year-old patient presents with anhedonia, fatigue, and sleep
disturbances for the last two months. As a Psychiatric-Mental
Health Nurse Practitioner (PMHNP), which initial diagnostic step is
most appropriate?
A) Order a brain MRI
B) Conduct a comprehensive psychiatric interview
C) Begin antidepressant therapy immediately
D) Recommend mindfulness training
Correct ,,,,answer,,,: B) Conduct a comprehensive psychiatric
interview
Rationale: A comprehensive psychiatric interview allows for a thorough
assessment of history, symptoms, and differential diagnoses before
initiating treatment. Imaging is reserved for suspected neurological
causes, and interventions should follow a confirmed assessment rather
,than being initiated immediately. The biopsychosocial model requires
integration of biological, psychological, and social domains during
initial assessment .
2. The PMHNP utilizing the biopsychosocial model considers which
of the following?
A) Only neurochemical imbalances
B) Psychological and environmental factors exclusively
C) Biological, psychological, and social domains
D) Family structure only
Correct ,,,,answer,,,: C) Biological, psychological, and social domains
Rationale: The biopsychosocial model integrates biological,
psychological, and social factors influencing mental illness. This
comprehensive approach is essential for accurate diagnosis and
treatment planning in psychiatric mental health practice .
3. Which neurotransmitter imbalance is most closely associated with
the positive symptoms of schizophrenia?
A) Decreased serotonin
B) Increased dopamine
C) Decreased glutamate
D) Increased GABA
Correct ,,,,answer,,,: B) Increased dopamine
,Rationale: Hyperactivity of dopamine in the mesolimbic pathway is
linked to hallucinations and delusions—the core positive symptoms of
schizophrenia. This is the basis for the dopamine hypothesis and the
mechanism of action for antipsychotic medications .
4. Depressive symptoms are associated with all of the following lab
findings EXCEPT:
A) Decreased nocturnal growth hormone secretion
B) Decreased thyroid-stimulating hormone response
C) Increased somatostatin in cerebrospinal fluid
D) Increased secretion of cortisol
Correct ,,,,answer,,,: C) Increased somatostatin in cerebrospinal
fluid
Rationale: Depressive symptoms are associated with decreased, not
increased, levels of somatostatin in cerebrospinal fluid. Patients with
depression may exhibit a decreased thyroid-stimulating hormone
response to thyrotropin-releasing hormone, as well as hypersecretion of
cortisol. Depressive symptoms are also associated with irregularities in
growth hormone release, such as reduced nocturnal secretion and diurnal
hypersecretion .
5. Which of the following medications is contraindicated with
concurrent MAOI usage?
, A) Sodium valproate
B) Escitalopram
C) Lithium
D) Haloperidol
Correct ,,,,answer,,,: B) Escitalopram
Rationale: SSRIs such as escitalopram are contraindicated with MAOIs
due to the risk of serotonin syndrome, a potentially life-threatening
condition caused by excessive serotonergic activity .
6. Which antidepressant carries the highest risk of hypertensive
crisis when combined with tyramine-rich foods?
A) Fluoxetine
B) Bupropion
C) Phenelzine
D) Sertraline
Correct ,,,,answer,,,: C) Phenelzine
Rationale: Phenelzine is an MAOI that inhibits tyramine metabolism,
leading to hypertensive crisis when combined with tyramine-rich foods
such as aged cheese, cured meats, and fermented products. This is a
critical patient education point .
7. A patient stabilized on clozapine should have which test
monitored regularly?
