standards. Each question features an italicized correct answer and a bolded, in-depth
rationale designed to mimic the exact pacing and style of the real board exams. It serves as
the ultimate digital study guide for nursing students and graduates aiming for a first-time
pass on their national board certifications.
📑 PMHNP High-Yield Board Review
1. A 28-year-old male diagnosed with schizophrenia is being started on
Clozapine (Clozaril). Which baseline laboratory parameter is the most
critical for the PMHNP to verify before initiating this medication?
A) Serum creatinine
B) Hemoglobin A1c
C) Absolute Neutrophil Count (ANC)
D) Liver function tests (LFTs)
Rationale: Clozapine carries a black box warning for severe
neutropenia and agranulocytosis. The PMHNP must verify that the
, baseline Absolute Neutrophil Count (ANC) is ≥ 1,500/μ L (≥ 1.5 × 10⁹/L)
before treatment initiation and monitor it regularly via the Clozapine
REMS registry.
2. A 34-year-old female patient presents with profound depressive symptoms,
hypersomnia, and a history of one severe manic episode requiring
hospitalization three years ago. Which of the following monotherapy
treatments is strictly contraindicated for this patient?
A) Sertraline (Zoloft)
B) Quetiapine (Seroquel)
C) Lurasidone (Latuda)
D) Lamotrigine (Lamictal)
Rationale: Anticipating or treating bipolar depression with
antidepressant monotherapy like Sertraline carries a high risk of
inducing treatment-emergent mania or rapid cycling. Bipolar I
depression must be managed with mood stabilizers or approved
atypical antipsychotics.
3. A patient taking Phenelzine (Nardil) for treatment-resistant depression
presents to the emergency department with a severe occipital headache,
palpitations, and a blood pressure of 210/125 mmHg. Which dietary or over-
the-counter indiscretion most likely triggered this crisis?
A) Eating a slice of fresh pepperoni pizza
B) Consuming aged cheddar cheese and red wine
C) Taking an extra dose of Acetaminophen
D) Drinking a cup of black chamomile tea
Rationale: Phenelzine is a Monoamine Oxidase Inhibitor (MAOI).
Consuming foods high in tyramine—such as aged cheeses, red wine,
and cured meats—inhibits the breakdown of tyramine, leading to a
, massive release of norepinephrine and a life-threatening
hypertensive crisis.
4. A 19-year-old college student presents with intense fear of gaining weight,
restricted caloric intake, and a Body Mass Index (BMI) of 16.2. The PMHNP
notes fine, downy hair on the patient's back and arms. What is the clinical
term for this finding?
A) Hirsutism
B) Lanugo
C) Alopecia
D) Acanthosis nigricans
Rationale: Lanugo is the growth of fine, soft, downy hair across the
body. It is a physiological compensatory mechanism seen in severe
anorexia nervosa as the body attempts to insulate itself due to the
loss of subcutaneous fat.
5. During a routine follow-up, a patient taking Lithium Carbonate for Bipolar
Disorder reports coarse hand tremors, persistent diarrhea, muscle
weakness, and blurred vision. What is the most appropriate immediate
action by the PMHNP?
A) Instruct the patient to drink more water and recheck in one week
B) Order a routine lithium level to be drawn at the next monthly visit
C) Hold the medication, order a stat serum lithium level, and evaluate for
toxicity
D) Reduce the dose by half and add Propranolol for the tremor
Rationale: Coarse tremors, gastrointestinal distress, weakness, and visual
changes are classic signs of advanced lithium toxicity (typically levels >1.5
mEq/L). The medication must be held immediately, and a stat serum level
must be ordered.
, 6. A 45-year-old female is diagnosed with Major Depressive Disorder and
Generalized Anxiety Disorder. She explicitly states she wants a medication
that will not cause sexual dysfunction or weight gain. Which agent is the
best choice?
A) Paroxetine (Paxil)
B) Bupropion (Wellbutrin)
C) Mirtazapine (Remeron)
D) Amitriptyline (Elavil)
Rationale: Bupropion is an atypical antidepressant that inhibits the reuptake
of norepinephrine and dopamine (NDRI). Unlike SSRIs/SNRIs, it does not
have serotonergic activity, making it highly unique for its lack of sexual side
effects and weight-neutral or weight-loss profile.
7. A patient with schizophrenia has been taking Haloperidol (Haldol) 5 mg
twice daily for six months. During the assessment, the PMHNP observes
involuntary, rhythmic smacking of the lips and repetitive tongue protrusion.
Which condition is developing?
A) Akathisia
B) Acute dystonia
C) Pseudoparkinsonism
D) Tardive dyskinesia
Rationale: Tardive dyskinesia (TD) is a late-onset, potentially irreversible
Extrapyramidal Symptom (EPS) caused by long-term dopamine receptor
blockade. It is characterized by involuntary choreoathetoid movements of
the face, tongue, and extremities.
8. Which neurodevelopmental pathway or brain structure is primarily
implicated in the executive dysfunction, poor working memory, and negative
symptoms observed in patients with Schizophrenia?
