Section I: Foundations of Psychotic Disorders
Core Concepts and DSM-5-TR Framework
,Question 1
A PMHNP is teaching a student about psychosis. Which statement best defines psychosis?
A. A temporary mood change caused by stress
B. A disturbance in reality testing involving hallucinations, delusions, or disorganized thinking
C. A personality pattern marked by attention-seeking behavior
D. A cognitive disorder caused only by aging
Correct Answer: B
Rationale: Psychosis involves impaired reality testing. The patient may misinterpret reality through
hallucinations, delusions, disorganized speech, or abnormal behavior.
Why Not the Other Options?
A: Stress may worsen symptoms but does not define psychosis.
C: This describes personality-related behavior, not psychosis.
D: Psychosis is not limited to aging or neurocognitive disorders.
Clinical Pearl: Psychosis is a symptom cluster, not a single diagnosis.
Question 2
Which symptom is considered a positive symptom of schizophrenia?
A. Avolition
B. Flat affect
C. Auditory hallucinations
D. Social withdrawal
Correct Answer: C
Rationale: Positive symptoms are added experiences or distortions of normal function, such as hallucinations,
delusions, and disorganized speech.
Why Not the Other Options?
A: Avolition is a negative symptom.

symptoms.

,Correct Answer: B
Rationale: A hallucination is a sensory perception without an external stimulus. Hearing voices is an auditory
hallucination.

Rationale: DSM-5-TR requires at least one core psychotic symptom: delusions, hallucinations, or disorganized
speech.
Why Not the Other Options?
B: Depressed mood is not required for schizophrenia.
C: Panic attacks are anxiety symptoms.
D: Memory loss is not a core requirement.
,Clinical Pearl: Schizophrenia diagnosis requires both symptom criteria and duration criteria.
Question 6
A patient says, “The TV news anchor is sending secret messages directly to me.” This is best described as:
A. Delusion of reference
B. Thought withdrawal
C. Echolalia
D. Catatonia
Correct Answer: A
Rationale: Delusions of reference occur when neutral events are believed to have special personal meaning.
Why Not the Other Options?
B: Thought withdrawal is belief that thoughts are being removed.
C: Echolalia is repetition of another person’s words.
D: Catatonia involves abnormal motor behavior.
Clinical Pearl: Delusions of reference may appear early in psychotic illness.
Question 7
Which symptom reflects disorganized thinking?
A. Loose associations
B. Avolition
C. Flat affect
D. Anhedonia
Correct Answer: A
Rationale: Disorganized thinking is commonly observed through speech patterns such as derailment,
tangentiality, incoherence, or loose associations.
Why Not the Other Options?
B: Avolition is reduced motivation.
C: Flat affect is reduced emotional expression.
D: Anhedonia is reduced ability to experience pleasure.
Clinical Pearl: Thought process is often assessed by listening carefully to speech organization.
Question 8
Which finding is a negative symptom?
A. Delusion
B. Hallucination
C. Alogia
D. Thought broadcasting
Correct Answer: C
,Rationale: Alogia means poverty of speech and is a negative symptom reflecting decreased normal function.
Why Not the Other Options?

Correct Answer: D
Rationale: DSM-5-TR requires continuous signs of disturbance for at least 6 months, including at least 1 month
of active-phase symptoms unless successfully treated.
Why Not the Other Options?
A: Too short for schizophrenia.
B: May fit brief active symptoms but not full schizophrenia duration.
C: More consistent with schizophreniform range, not schizophrenia.
Clinical Pearl: Duration helps distinguish schizophrenia from brief psychotic disorder and schizophreniform
disorder.
Question 10

A. Thought insertion
B. Thought withdrawal
C. Thought broadcasting
D. Somatic delusion

B: This describes delusions, not hallucinations.
C: Hallucinations can occur while awake.
D: Illusions may occur with fatigue, stress, or poor lighting and are not always psychotic.
Clinical Pearl: Clarifying whether a stimulus was present helps separate hallucination from illusion.

most likely?
A. Flat affect
B. Grandiosity
,C. Pressured speech

A. Tangentiality
B. Echopraxia
C. Catalepsy
D. Anhedonia
