Health NP Review
Question 1: A 28-year-old client presents with recurrent,
unexpected episodes of intense fear that peak within 10 minutes,
accompanied by palpitations, diaphoresis, and a fear of "losing
control." The episodes occur without a specific trigger. Which
diagnosis is most appropriate?
A. Generalized Anxiety Disorder
B. Panic Disorder
C. Social Anxiety Disorder
D. Illness Anxiety Disorder
CORRECT ANSWER: B. Panic Disorder
Rationale: Panic Disorder is characterized by recurrent, unexpected panic
attacks that peak within minutes, followed by at least one month of
persistent concern about additional attacks or maladaptive behavioral
changes. The absence of a specific trigger distinguishes it from situational
anxiety, and the discrete episodic nature differentiates it from Generalized
Anxiety Disorder.
Question 2: A PMHNP is prescribing an SSRI to an adolescent with
Major Depressive Disorder. The FDA requires a Black Box Warning
for this medication class regarding which risk?
A. Hypertensive crisis
B. Suicidal ideation
C. Agranulocytosis
D. QTc prolongation
CORRECT ANSWER: B. Suicidal ideation
Rationale: The FDA requires a Black Box Warning for all antidepressants
regarding an increased risk of suicidal thinking and behavior in children,
adolescents, and young adults under age 25. This necessitates close
monitoring during initiation and dose changes.
Question 3: Which therapeutic communication technique involves
the PMHNP restating the client's message in different words to
confirm understanding?
A. Clarification
,B. Paraphrasing
C. Reflection
D. Confrontation
CORRECT ANSWER: B. Paraphrasing
Rationale: Paraphrasing involves restating the client's message in the
nurse's own words to verify that the message received matches the message
intended. Clarification seeks additional detail, while reflection focuses on
feelings rather than content.
Question 4: A 68-year-old client on long-term haloperidol presents
with involuntary, repetitive lip smacking and tongue movements.
This presentation is most consistent with which condition?
A. Acute dystonia
B. Akathisia
C. Tardive dyskinesia
D. Neuroleptic malignant syndrome
CORRECT ANSWER: C. Tardive dyskinesia
Rationale: Tardive dyskinesia is a late-onset extrapyramidal symptom
characterized by involuntary, repetitive movements of the tongue, lips, face,
or extremities. It typically emerges after months to years of antipsychotic
treatment, particularly with first-generation agents.
Question 5: A PMHNP is assessing a 6-year-old child with
tantrums, defiance, and argumentative behavior toward authority
figures that has persisted for 8 months. Which diagnosis should be
considered?
A. Oppositional Defiant Disorder
B. Conduct Disorder
C. Intermittent Explosive Disorder
D. Disruptive Mood Dysregulation Disorder
CORRECT ANSWER: A. Oppositional Defiant Disorder
Rationale: Oppositional Defiant Disorder involves a persistent pattern of
angry/irritable mood, argumentative/defiant behavior, or vindictiveness
lasting at least 6 months. Conduct Disorder involves more severe violations
of rights of others, and DMDD requires severe recurrent temper outbursts
occurring 3 or more times per week.
,Question 6: A client taking lithium reports increased urination and
excessive thirst. Which laboratory monitoring parameter is most
critical to assess?
A. Serum sodium
B. Serum potassium
C. Renal function
D. Liver enzymes
CORRECT ANSWER: C. Renal function
Rationale: Lithium is excreted renally and can cause nephrogenic diabetes
insipidus, presenting as polyuria and polydipsia. Long-term lithium use can
impair renal concentrating ability and potentially cause chronic kidney
disease, requiring regular monitoring of BUN, creatinine, and eGFR.
Question 7: Which neurotransmitter system is primarily implicated
in the therapeutic mechanism of benzodiazepines?
A. Serotonergic
B. Dopaminergic
C. GABAergic
D. Noradrenergic
CORRECT ANSWER: C. GABAergic
Rationale: Benzodiazepines enhance the inhibitory effects of gamma-
aminobutyric acid (GABA) at GABA-A receptors, increasing chloride
channel conductance and neuronal hyperpolarization. This produces
anxiolytic, sedative, and anticonvulsant effects.
Question 8: A PMHNP suspects a client is malingering. Which
feature is most characteristic of this presentation?
A. Symptoms that fluctuate with observation
B. Unintentional production of symptoms
C. Symptoms consistent with a known medical condition
D. Clear secondary gain associated with symptom production
CORRECT ANSWER: D. Clear secondary gain associated with
symptom production
Rationale: Malingering involves the intentional production or exaggeration
of symptoms for a recognizable external incentive, such as financial
compensation, avoidance of work, or obtaining controlled substances. This
differs from factitious disorder, where the motivation is internal.
, Question 9: During a mental status examination, a client describes
their mood as "fine" but appears tearful and speaks in a monotone
voice. This finding should be documented as which type of
discrepancy?
A. Mood-congruent
B. Mood-incongruent
C. Appropriate affect
D. Anhedonia
CORRECT ANSWER: B. Mood-incongruent
Rationale: Mood-incongruent affect describes a mismatch between the
client's stated mood and observed affective expression. The client reports
feeling "fine" (euthymic mood) while displaying tearfulness (depressed
affect), which are incongruent with one another.
Question 10: A PMHNP is considering prescribing clozapine for
treatment-resistant schizophrenia. Which laboratory test must be
performed at baseline and regularly throughout treatment?
A. Liver function tests
B. Absolute neutrophil count
C. Serum lithium level
D. Thyroid stimulating hormone
CORRECT ANSWER: B. Absolute neutrophil count
Rationale: Clozapine carries a significant risk of agranulocytosis,
necessitating mandatory ANC monitoring at baseline and regularly
throughout treatment. In the United States, a Risk Evaluation and
Mitigation Strategy (REMS) program mandates this monitoring.
Question 11: A client with Borderline Personality Disorder is using
splitting during a hospitalization. Which staff response is most
therapeutic?
A. Assigning different staff members to each shift
B. Maintaining consistent team communication and boundaries
C. Allowing the client to choose preferred staff members
D. Confronting the client about manipulative behavior
CORRECT ANSWER: B. Maintaining consistent team
communication and boundaries
