SECTION 1: CORE CONCEPTS & SYMPTOM IDENTIFICATION Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 22-year-old man is brought to the emergency department by campus police after
barricading himself in his dorm room, claiming that "government agents have planted
microphones in the walls." His roommate states that over the past 8 months, the patient has
gradually stopped attending classes, withdrawn from friends, and begun talking to himself.
During the mental status examination, the patient maintains fixed eye contact and states, "I
know they are listening." The psychiatric nurse practitioner is evaluating whether the patient
meets DSM-5-TR criteria for schizophrenia and recognizes that the essential presenting
feature is:
A. Two or more Criterion A symptoms, such as delusions, hallucinations, or disorganized
speech, present for a significant portion of time during at least 1 month ✓ CORRECT
B. Continuous signs of disturbance for at least 6 months including prodromal or residual
periods
C. Marked impairment in social or occupational functioning below the level achieved prior to
onset
D. Exclusion of substance use or another medical condition causing the disturbance
Correct Answer: A
Rationale: Criterion A requires two or more characteristic symptoms—delusions,
hallucinations, disorganized speech, grossly disorganized or catatonic behavior, or negative
symptoms—present for at least 1 month, and this patient demonstrates delusions and likely
hallucinations. While options B, C, and D represent necessary diagnostic criteria, they are not
the essential presenting symptom cluster that defines the psychotic nature of schizophrenia.
On ATI exams, watch for questions that ask for the defining feature versus the duration or
exclusion criteria.
,Question 2 of 50
A 34-year-old woman diagnosed with schizophrenia 10 years ago presents to the outpatient
clinic with her husband. She reports hearing a voice that comments on her actions
throughout the day, and she believes her husband is poisoning her food. Her husband states
that she has also experienced periods of major depression lasting 3 weeks during the past
year, occurring independently of her psychotic symptoms. The nurse practitioner considers
that this clinical picture is most consistent with:
A. Schizophrenia with co-occurring major depressive disorder
B. Schizoaffective disorder ✓ CORRECT
C. Delusional disorder with depressive features
D. Brief psychotic disorder with mood episodes
Correct Answer: B
Rationale: Schizoaffective disorder is diagnosed when a major mood episode—major
depression or mania—occurs concurrently with Criterion A symptoms of schizophrenia and
persists for a majority of the total illness duration. The key distinction from schizophrenia
with depression is that in schizoaffective disorder, mood symptoms are present for the
majority of the illness and psychotic symptoms persist for at least 2 weeks without mood
symptoms. Delusional disorder lacks the breadth of hallucinations and functional decline
seen here, and brief psychotic disorder resolves within 1 month.
Question 3 of 50
A 19-year-old man is admitted to the inpatient psychiatric unit after his parents found him
wandering the neighborhood at 3 AM, stating he needed to "warn the neighbors about the
electromagnetic waves." His parents report that over the past 4 months, he has become
increasingly isolated, stopped showering, and mutters under his breath. His grades dropped
from A's to F's during the last semester. The interdisciplinary team identifies these
pre-psychotic changes as:
A. Residual phase symptoms indicating recovery from an acute episode
B. Active-phase symptoms meeting Criterion A for schizophrenia
C. Prodromal symptoms that often precede the first psychotic break ✓ CORRECT
D. Negative symptoms that emerge during the chronic phase of illness
Correct Answer: C
Rationale: Prodromal symptoms include gradual changes in behavior, social withdrawal,
deterioration in hygiene, and declining academic or occupational performance that frequently
precede the onset of full psychotic symptoms by months or years. These are not residual
symptoms, which occur after an acute episode, nor are they active-phase symptoms, which
require the presence of delusions, hallucinations, or disorganized speech. ATI frequently
tests the ability to distinguish prodromal, active, and residual phases of schizophrenia.
, Question 4 of 50
A 28-year-old woman has held the belief for 3 years that her coworker is romantically
obsessed with her, despite no evidence and repeated clarifications from the coworker and
human resources. She has filed multiple police reports and refuses to attend work functions
where the coworker might be present. Aside from this preoccupation, she maintains her
apartment, pays bills on time, and has no hallucinations or thought disorder. The nurse
practitioner recognizes this presentation as most consistent with:
A. Paranoid schizophrenia with well-preserved cognition
B. Schizoaffective disorder, delusional type
C. Shared psychotic disorder (folie à deux)
D. Delusional disorder, erotomanic type ✓ CORRECT
Correct Answer: D
Rationale: Delusional disorder is characterized by one or more delusions lasting at least 1
month in the absence of other psychotic symptoms such as hallucinations, disorganized
speech, or marked functional impairment, and this patient's erotomanic delusion fits this
pattern precisely. Paranoid schizophrenia requires Criterion A symptoms including
hallucinations or disorganized speech and significant functional decline, which are absent
here. A key ATI trap is selecting schizophrenia when the presentation is isolated to
non-bizarre delusions without broader psychotic features.
Question 5 of 50
A 45-year-old man is brought to the emergency department by his wife after he suddenly
began screaming that "demons are crawling through the vents" and attempted to attack the
air conditioning unit with a baseball bat. He has no prior psychiatric history, denies substance
use, and medical workup is negative. His symptoms began 4 days ago and have been present
continuously. By hospital day 6, his symptoms have completely resolved and he is back to
baseline. The nurse documents this episode as most consistent with:
A. Schizophreniform disorder
B. Brief psychotic disorder ✓ CORRECT
C. Schizoaffective disorder
D. Substance-induced psychotic disorder
Correct Answer: B
Rationale: Brief psychotic disorder involves the sudden onset of one or more positive
psychotic symptoms—delusions, hallucinations, disorganized speech, or grossly
disorganized behavior—lasting at least 1 day but less than 1 month, with eventual full return
to premorbid functioning. Schizophreniform disorder requires symptoms lasting 1 to 6
months, and schizoaffective disorder requires mood episodes concurrent with psychotic
