,SECTION 1: SCHIZOPHRENIA SPECTRUM AND PSYCHOTIC DISORDERS
Question 1
The negative schizophrenic symptom called avolition is defined as:
A. Lack of emotional response, blank facial expression
B. Inability to initiate and persist in activities
C. Inability to experience pleasure
D. Lack of speech content and/or slowed speech response
Correct Answer: B. Inability to initiate and persist in activities
Rationale: Avolition refers to a decrease in the motivation to initiate and
perform self-directed purposeful activities. This is a negative symptom of
schizophrenia that significantly impacts daily functioning.
- Option A describes blunted affect (also called affective flattening)
- Option C describes anhedonia
- Option D describes alogia
Understanding these distinct negative symptoms is crucial for accurate
assessment and treatment planning in schizophrenia.
,Question 2
Which of the following characteristics are features of schizophrenia according
to DSM-5 criteria?
A. Delusions and hallucinations
B. Labile emotions
C. Obsessions and rituals
D. All of these
Correct Answer: A. Delusions and hallucinations
Rationale: According to DSM-5 criteria for schizophrenia, the core positive
symptoms include delusions and hallucinations.
- Labile emotions are not a diagnostic criterion for schizophrenia
- Obsessions and rituals are characteristic of obsessive-compulsive disorder
(OCD), not schizophrenia
- While some patients may experience mood symptoms, these are not primary
diagnostic features
The DSM-5 requires at least two of the following: delusions, hallucinations,
disorganized speech, grossly disorganized or catatonic behavior, or negative
symptoms, with at least one being delusions, hallucinations, or disorganized
speech.
, Question 3
A 26-year-old female with schizoaffective disorder complains of missing her
period and having milk discharge from her breasts. She has no signs of
pregnancy, including a negative pregnancy test. Which of the following might
have caused these findings?
A. Aripiprazole (Abilify)
B. Risperidone (Risperdal)
C. Escitalopram (Lexapro)
D. Asenapine (Saphris)
Correct Answer: B. Risperidone (Risperdal)
Rationale:Risperidone is associated with significant hyperprolactinemia due to
its potent blockade of D2 receptors in the tuberoinfundibular pathway. This
leads to:
- Amenorrhea (missed periods)
- Galactorrhea (milk discharge)
- Gynecomastia in males
- Decreased libido
The tuberoinfundibular dopamine pathway governs prolactin release. When D2
receptors are blocked in this pathway, prolactin levels increase. Aripiprazole is
actually associated with LOWER prolactin levels as it is a partial D2 agonist.
SSRIs like escitalopram can mildly increase prolactin but not typically to this
degree.
