1. A 32-year-old patient presents with depressed mood,
anhedonia, fatigue, insomnia, impaired concentration, and
feelings of worthlessness for the past 6 weeks. The symptoms
significantly interfere with occupational functioning. Which
diagnosis best describes this presentation?
A. Persistent depressive disorder
B. Adjustment disorder with depressed mood
C. Major depressive disorder
D. Cyclothymic disorder
<i>Rationale: Major depressive disorder is characterized by at
least 2 weeks of depressed mood or anhedonia accompanied
by additional cognitive, behavioral, and physical symptoms
that cause clinically significant distress or impairment. The
duration, symptom pattern, and functional impairment in this
case are consistent with a major depressive episode.</i>
,2. A patient taking an SSRI reports nausea and mild headache
during the first week of treatment. There are no other concerning
symptoms. What is the most appropriate PMHNP response?
A. Discontinue the medication immediately
B. Switch immediately to an antipsychotic
C. Double the dose to overcome the adverse effects
D. Explain that these effects can occur early in treatment and
monitor symptoms
<i>Rationale: Gastrointestinal symptoms and headache are
common early adverse effects of SSRIs and often improve
with continued treatment. Unless symptoms are severe or
dangerous, patient education and monitoring are generally
appropriate rather than abrupt discontinuation.</i>
3. Which neurotransmitter is most strongly associated with the
pathophysiology of schizophrenia?
A. Acetylcholine only
B. GABA only
C. Dopamine
D. Melatonin
<i>Rationale: Dopaminergic dysregulation is strongly
implicated in schizophrenia. Excess dopamine activity in
certain pathways, particularly the mesolimbic pathway, is
associated with positive symptoms, while reduced dopamine
activity in other pathways has been associated with negative
and cognitive symptoms.</i>
,4. A patient experiencing auditory hallucinations states, “The
voices are telling me that I am worthless.” Which response is
most therapeutic?
A. “Those voices are real, and you should listen carefully.”
B. “You need to stop thinking about the voices.”
C. “I understand that you hear the voices, but I do not hear
them. Let’s discuss what they are saying and how they affect
you.”
D. “There is nothing wrong with you.”
<i>Rationale: The response acknowledges the patient's
experience without validating the hallucination as an external
reality. Exploring the content and emotional impact of
hallucinations also helps assess safety, including possible
command hallucinations.</i>
5. A patient with bipolar I disorder presents with decreased need
for sleep, pressured speech, grandiosity, racing thoughts, and
excessive spending. Which episode is most consistent with these
findings?
A. Hypomanic episode
B. Major depressive episode
C. Manic episode
D. Mixed anxiety episode
<i>Rationale: A manic episode involves a distinct period of
abnormally elevated, expansive, or irritable mood
accompanied by increased energy or activity and associated
symptoms such as decreased need for sleep, pressured
, speech, grandiosity, and risky behavior. Bipolar I disorder
requires a history of at least one manic episode.</i>
6. Which medication is commonly used as a mood stabilizer in
the long-term management of bipolar disorder?
A. Fluoxetine
B. Buspirone
C. Lithium
D. Methylphenidate
<i>Rationale: Lithium is an established mood stabilizer used
for acute mania and maintenance treatment in bipolar
disorder. It can reduce the frequency and severity of mood
episodes and requires appropriate monitoring because of its
narrow therapeutic index.</i>
7. A patient taking lithium develops coarse tremor, vomiting,
severe diarrhea, and confusion. What should the PMHNP
suspect?
A. Serotonin deficiency
B. Anticholinergic toxicity
C. Lithium toxicity
D. Neuroleptic malignant syndrome
<i>Rationale: Gastrointestinal symptoms, worsening tremor,
confusion, and neurologic changes can indicate lithium
toxicity. Significant toxicity requires prompt clinical evaluation
and assessment of serum lithium concentration, renal
function, hydration status, and other contributing factors.</i>
