A/B/C PERSONALITY DISORDERS, AND CLINICAL DECISION-
MAKING FOR THE FNP/PMHNP STUDENT
QUESTION 1: A 32-year-old woman reports depressed mood,
anhedonia, fatigue, and poor concentration for 3 weeks. She also has
increased appetite and sleeps 11 hours per night. What is the most
likely diagnosis?
A) Major depressive disorder, melancholic features
B) Major depressive disorder, atypical features
C) Persistent depressive disorder
D) Bipolar II disorder, current episode depressed
CORRECT ANSWER: B) Major depressive disorder, atypical features
RATIONALE: Atypical features of MDD include hypersomnia,
hyperphagia (increased appetite), leaden paralysis, and mood reactivity.
Melancholic features involve early morning awakening, anorexia, and
worse mood in the morning. Persistent depressive disorder requires ≥2
years of symptoms. There is no history of hypomania, so bipolar II is not
supported.
QUESTION 2: A patient experiences recurrent panic attacks followed by
4 months of persistent worry about having another attack. He avoids
the gym where the first attack occurred. What diagnosis best fits?
,A) Panic disorder
B) Agoraphobia
C) Social anxiety disorder
D) Panic disorder with agoraphobia
CORRECT ANSWER: D) Panic disorder with agoraphobia
RATIONALE: The patient meets criteria for panic disorder (recurrent
unexpected panic attacks + ≥1 month of worry/behavior change) and
also avoids a specific place (gym) due to fear of difficulty escaping –
meeting agoraphobia criteria. Panic disorder alone would not include
avoidance. Agoraphobia alone can occur without panic attacks.
QUESTION 3: A 45-year-old male with schizophrenia has been on
haloperidol for 2 years. He now presents with repetitive, involuntary
movements of his tongue, lips, and face. Which condition is MOST
likely?
A) Akathisia
B) Neuroleptic malignant syndrome
C) Parkinson's disease
D) Tardive dyskinesia
E) Acute dystonia
CORRECT ANSWER: D) Tardive dyskinesia
RATIONALE: Tardive dyskinesia (TD) is a late-onset movement disorder
associated with prolonged use of dopamine receptor-blocking agents
such as haloperidol. It is characterized by repetitive, involuntary
orofacial movements and can be irreversible. Valbenazine (Ingrezza) or
deutetrabenazine (Austedo) are FDA-approved treatments.
,QUESTION 4: A 22-year-old college student presents with recurrent,
unexpected panic attacks, persistent worry about future attacks, and
avoidance of places where attacks have occurred for 5 months. What is
the BEST first-line pharmacological treatment?
A) Alprazolam (Xanax)
B) Buspirone (Buspar)
C) Sertraline (Zoloft)
D) Propranolol (Inderal)
E) Clonazepam (Klonopin)
CORRECT ANSWER: C) Sertraline (Zoloft)
RATIONALE: SSRIs such as sertraline are the first-line pharmacological
treatment for panic disorder per APA guidelines. Benzodiazepines may
provide short-term relief but are not recommended as first-line due to
dependence risk. Buspirone is effective for GAD but not panic disorder.
QUESTION 5: A 16-year-old is brought in by parents for evaluation. She
has restricted food intake, intense fear of gaining weight, distorted body
image, and her BMI is 15.5. Which diagnosis is MOST appropriate?
A) Bulimia nervosa
B) Binge eating disorder
C) Avoidant/restrictive food intake disorder (ARFID)
D) Anorexia nervosa, restricting type
E) Body dysmorphic disorder
CORRECT ANSWER: D) Anorexia nervosa, restricting type
, RATIONALE: Anorexia nervosa is characterized by restricted energy
intake, intense fear of weight gain, and distorted body image leading to
significantly low body weight (BMI <17.5 in adults). The restricting
subtype does not involve binge/purge behaviors. ARFID lacks the fear of
weight gain and body image distortion.
QUESTION 6: A PMHNP is evaluating a patient who takes lithium. The
patient's serum lithium level is 1.8 mEq/L and presents with coarse
tremor, confusion, and nausea. What is the PRIORITY intervention?
A) Reduce the lithium dose by half
B) Administer activated charcoal
C) Discontinue lithium and initiate hemodialysis
D) Switch to valproate immediately
E) Increase fluid intake and monitor
CORRECT ANSWER: C) Discontinue lithium and initiate hemodialysis
RATIONALE: Lithium levels above 1.5 mEq/L indicate toxicity, and levels
above 1.5–2.0 mEq/L with neurological symptoms (coarse tremor,
confusion) require immediate discontinuation. Hemodialysis is indicated
for severe toxicity (levels >2.5 mEq/L or severe symptoms at lower
levels). Toxic signs include SHALT: Slurred speech, Hyperreflexia, Ataxia,
Large tremors, Tachycardia.
QUESTION 7: A 68-year-old presents with progressive memory loss,
getting lost in familiar places, difficulty with ADLs, and personality
changes over 2 years. Her daughter reports she has been aggressive and
confused at night. Which diagnosis is MOST likely?
