1. A 19-year-old patient presents with symptoms of auditory hallucinations and social
withdrawal that have persisted for exactly four months. According to DSM-5 criteria, which of
the following is the most appropriate provisional diagnosis?
A. Schizophrenia
B. Brief Psychotic Disorder
C. Schizoaffective Disorder
D. Schizophreniform Disorder
Answer: D
Rationale: Schizophreniform disorder is characterized by symptoms identical to
schizophrenia but with a duration of at least one month but less than six months. If the
symptoms persist beyond six months, the diagnosis would then be updated to
schizophrenia. This diagnostic category serves as a vital bridge for patients who show
significant impairment but do not yet meet the longitudinal requirements for a chronic
diagnosis.
,2. In the assessment of a child suspected of having Autism Spectrum Disorder (ASD), which of
the following clinical features is considered a core diagnostic requirement?
A. Standardized IQ scores below the average range
B. A history of significant language delay and regression
C. Persistent deficits in social communication and social interaction
D. Presence of visual hallucinations and thought blocking
Answer: C
Rationale: The DSM-5-TR identifies deficits in social communication and social interaction
across multiple contexts as a primary criterion for ASD. These deficits must be persistent
and manifest in areas like social-emotional reciprocity and nonverbal communication.
While other symptoms may occur, they are not the central defining feature required for
this specific neurodevelopmental diagnosis.
3. A clinician is evaluating a 28-year-old woman who exhibits a pervasive pattern of instability
in interpersonal relationships, self-image, and affects, along with marked impulsivity. Which
personality disorder is most likely represented?
A. Borderline Personality Disorder
B. Histrionic Personality Disorder
C. Avoidant Personality Disorder
D. Dependent Personality Disorder
,Answer: A
Rationale: Borderline Personality Disorder is defined by a consistent pattern of instability
regarding moods, self-perception, and relationships. Patients often experience intense
episodes of anger, depression, and anxiety that can last from a few hours to days. It is
essential to differentiate this from other Cluster B disorders by focusing on the core fear of
abandonment and the tendency toward self-harm or suicidal ideation.
4. Which of the following is a key differentiator between Bulimia Nervosa and the Binge-
Eating/Purging type of Anorexia Nervosa?
A. The presence of compensatory behaviors like vomiting
B. The patient’s body weight relative to the minimum normal range
C. A distorted perception of body shape and size
D. The frequency of binge-eating episodes per week
Answer: B
Rationale: Anorexia Nervosa is primarily distinguished by significantly low body weight
that is less than minimally normal for the individual’s age and height. In contrast,
individuals with Bulimia Nervosa typically maintain a body weight that is at or above the
minimally normal level. This weight criterion is a fundamental clinical marker used to
separate these two eating disorders during the diagnostic process.
, 5. A 10-year-old boy frequently loses his temper, argues with authority figures, and refuses to
comply with requests. These behaviors have occurred for seven months but do not involve
physical aggression or destruction of property. What is the most likely diagnosis?
A. Conduct Disorder
B. Disruptive Mood Dysregulation Disorder
C. Oppositional Defiant Disorder
D. Intermittent Explosive Disorder
Answer: C
Rationale: Oppositional Defiant Disorder (ODD) involves a pattern of angry/irritable
mood, argumentative/defiant behavior, or vindictiveness. Unlike Conduct Disorder, ODD
does not typically involve the violation of the basic rights of others or major age-
appropriate societal norms. The duration of at least six months meets the diagnostic
threshold for a child in this age group.
6. A patient reports experiencing a sudden onset of paralysis in his right arm following a
severe emotional trauma, despite a completely normal neurological workup. Which diagnosis
fits this clinical picture?
A. Factitious Disorder
B. Somatic Symptom Disorder
C. Illness Anxiety Disorder
D. Conversion Disorder (Functional Neurological Symptom Disorder)
