This comprehensive post-test covers the core knowledge areas required for the Psychiatric
Mental Health Nurse Practitioner (PMHNP) certification exam. Questions reflect the latest
DSM-5-TR diagnostic criteria, evidence-based pharmacotherapy, psychotherapy modalities, and

clinical reasoning.
SECTION 1: PSYCHIATRIC DISORDERS – DIAGNOSIS & CLINICAL PRESENTATION
1. A 24-year-old woman presents with a 2-week history of elevated mood, decreased need
for sleep, grandiosity, and increased goal-directed activity. She reports that her thoughts are
racing and she has been spending money impulsively. Her symptoms are severe enough to
cause impairment in her job. She has no prior psychiatric history. Which diagnosis is most
likely?
A) Bipolar I disorder, manic episode
B) Bipolar II disorder, hypomanic episode
C) Cyclothymic disorder
D) Major depressive disorder with mixed features
✔✔ Correct Answer ✔✔ A
Rationale: The patient meets full criteria for a manic episode: elevated mood, decreased need
for sleep, grandiosity, racing thoughts, increased goal-directed activity, and impairment. No
prior episodes are required for a first diagnosis of bipolar I disorder. Hypomania would not
cause marked impairment or require hospitalization. Cyclothymia involves numerous periods of
hypomanic and depressive symptoms over at least 2 years.

2. A 32-year-old man presents with auditory hallucinations, disorganized speech, and
negative symptoms including flat affect and avolition. Symptoms have been present for 8
months. Which diagnosis is most appropriate?
A) Schizoaffective disorder
B) Schizophreniform disorder
C) Schizophrenia
D) Brief psychotic disorder
✔✔ Correct Answer ✔✔ C
Rationale: Schizophrenia requires continuous signs of disturbance for at least 6 months,
including at least 1 month of active phase symptoms (delusions, hallucinations, disorganized
speech, grossly disorganized or catatonic behavior, negative symptoms). Schizophreniform
disorder is diagnosed when duration is 1–6 months. Brief psychotic disorder lasts less than 1
month.
3. A 45-year-old woman reports recurrent panic attacks for the past 4 months. She describes
sudden episodes of heart palpitations, sweating, trembling, and fear of losing control. She has
been avoiding driving on highways and has stopped going to crowded places because she is
afraid of having another attack. What is the most likely diagnosis?
A) Panic disorder with agoraphobia
B) Generalized anxiety disorder
C) Social anxiety disorder
D) Specific phobia
✔✔ Correct Answer ✔✔ A
Rationale: Panic disorder is characterized by recurrent unexpected panic attacks followed by at
least 1 month of persistent concern about additional attacks or a maladaptive change in
behavior related to the attacks (such as avoidance). Agoraphobia is frequently comorbid and in
this case the avoidance of driving and crowded places meets criteria for agoraphobia.
4. A 19-year-old college student reports excessive worry about grades, relationships, and
health for the past 2 years. She states she “cannot stop worrying” and has difficulty
concentrating, muscle tension, and sleep disturbance. What is the most likely diagnosis?
A) Generalized anxiety disorder (GAD)
B) Panic disorder
,3
C) Obsessive-compulsive disorder
D) Adjustment disorder with anxiety
✔✔ Correct Answer ✔✔ A
Rationale: GAD involves excessive anxiety and worry occurring more days than not for at least 6
months, associated with three or more of the following: restlessness, easy fatigability, difficulty
concentrating, irritability, muscle tension, sleep disturbance. The 2-year duration and multiple
worry domains support GAD.
5. A 28-year-old man reports that he experiences recurrent, intrusive thoughts of harming his
family, which cause him significant distress. To neutralize these thoughts, he repeatedly
checks that the stove is off and locks and unlocks doors multiple times before leaving the
house. What is the most likely diagnosis?
A) Obsessive-compulsive disorder (OCD)
B) Generalized anxiety disorder
C) Specific phobia
D) Illness anxiety disorder
✔✔ Correct Answer ✔✔ A
Rationale: OCD is characterized by obsessions (recurrent, intrusive thoughts) and/or
compulsions (repetitive behaviors performed to reduce distress). The patient’s intrusive
thoughts of harming his family are obsessions, and his checking rituals are compulsions. The
symptoms are time-consuming and cause distress.
6. A 55-year-old man presents with a 3-month history of depressed mood, anhedonia, weight
loss, insomnia, and difficulty concentrating. He reports feeling worthless and has thoughts of
death. He has never had a manic or hypomanic episode. What is the most appropriate
diagnosis?
A) Major depressive disorder, single episode
B) Persistent depressive disorder (dysthymia)
C) Adjustment disorder with depressed mood
D) Bipolar II disorder, current episode depressed
✔✔ Correct Answer ✔✔ A
Rationale: The patient meets criteria for a major depressive episode (≥5 symptoms including
depressed mood or anhedonia, present for ≥2 weeks). Since there is no history of mania or
, 4
hypomania, major depressive disorder is the correct diagnosis. Persistent depressive disorder
would require chronic symptoms for at least 2 years.
7. A 22-year-old woman presents with unstable relationships, impulsivity, recurrent suicidal
gestures, and a chronic feeling of emptiness. She reports intense anger and rapid shifts in
mood. Which personality disorder is most consistent?
A) Borderline personality disorder
B) Narcissistic personality disorder
C) Histrionic personality disorder
D) Antisocial personality disorder
✔✔ Correct Answer ✔✔ A
Rationale: Borderline personality disorder is characterized by a pervasive pattern of instability
in interpersonal relationships, self-image, and affect, along with marked impulsivity. Key
features include frantic efforts to avoid abandonment, identity disturbance, impulsivity, suicidal
behavior, affective instability, chronic emptiness, and anger dyscontrol.
8. A 16-year-old boy is brought to the clinic by his parents due to a 6-month history of
irritability, argumentativeness, and vindictiveness toward his siblings. He often loses his
temper and deliberately annoys others. His symptoms occur only at home and not at school.
What is the most likely diagnosis?
A) Oppositional defiant disorder (ODD)
B) Conduct disorder
C) Intermittent explosive disorder
D) Disruptive mood dysregulation disorder
✔✔ Correct Answer ✔✔ A
Rationale: ODD is characterized by a pattern of angry/irritable mood, argumentative/defiant
behavior, or vindictiveness lasting at least 6 months. The symptoms occur only at home (not
across multiple settings) and do not include aggression toward people or animals, property
destruction, or theft, which would be more consistent with conduct disorder.
9. A 70-year-old woman is brought in by her daughter because of increasing forgetfulness
over the past year. She misplaces items, repeats questions, and has difficulty managing her
finances. She remains socially engaged and her personality is unchanged. On cognitive
