SECTION 1: FOUNDATIONS OF PSYCHOPATHOLOGY AND DIAGNOSTIC REASONING
──────────────────────────────
Question 1
A psychiatric-mental health nurse practitioner (PMHNP) is evaluating a 34-year-old male
who reports that he "feels disconnected from his body" during stressful meetings and
watches himself from above as if in a movie. The patient is alert, oriented, and
distressed by these episodes. Which diagnostic consideration is most appropriate?
A. Psychotic disorder due to the perceptual disturbance
B. Dissociative symptom consistent with depersonalization
C. Absence seizure disorder requiring neurological referral
D. Factitious disorder with psychological symptoms
Correct Answer:
B — Dissociative symptom consistent with depersonalization
Rationale:
Depersonalization involves persistent or recurrent experiences of unreality, detachment,
or feeling like an outside observer of one's thoughts, feelings, or body. The preserved
reality testing and distress distinguish it from psychosis. Absence seizures involve brief
lapses in consciousness without complex perceptual experiences, and factitious
disorder requires evidence of intentional symptom production.
Question 2
,A PMHNP is conducting a mental status examination on a 28-year-old female admitted
for major depressive disorder. The patient maintains minimal eye contact, speaks in
monosyllables, and exhibits slowed movements. Which mental status domain is
primarily being assessed through observation of these characteristics?
A. Thought process and content
B. Appearance, behavior, and psychomotor activity
C. Sensorium and cognition
D. Insight and judgment
Correct Answer:
B — Appearance, behavior, and psychomotor activity
Rationale:
Eye contact, speech patterns, and movement speed are core observational components
of the appearance, behavior, and psychomotor activity domain. Psychomotor
retardation is a hallmark of melancholic depression. Thought process refers to how
ideas are connected, sensorium to orientation and memory, and insight/judgment to
self-awareness and decision-making capacity.
Question 3
A 45-year-old patient presents with symptoms that began three weeks after a motor
vehicle accident. The PMHNP learns that the patient was not injured but witnessed a
fatality. The patient now has recurrent nightmares, hypervigilance while driving, and
avoids the intersection where the accident occurred. Which temporal criterion is most
relevant to the diagnostic formulation?
A. Symptoms lasting more than six months
B. Symptoms beginning after exposure to actual or threatened death, serious injury, or
sexual violence
C. Symptoms present before age 10 years
D. Symptoms occurring exclusively during periods of substance intoxication
,Correct Answer:
B — Symptoms beginning after exposure to actual or threatened death, serious injury, or
sexual violence
Rationale:
The diagnostic criteria for PTSD and acute stress disorder require exposure to a
Criterion A stressor involving actual or threatened death, serious injury, or sexual
violence, with subsequent symptom development. The six-month duration criterion
applies to PTSD but not acute stress disorder, and the scenario describes neither
childhood onset nor substance-induced symptoms.
Question 4
During diagnostic formulation, a PMHNP considers that a patient's depressive
symptoms may be attributable to hypothyroidism. Which principle of diagnostic
reasoning is being applied?
A. Differential diagnosis considering medical etiologies
B. Confirmation bias favoring a psychiatric explanation
C. Premature closure before completing the assessment
D. Anchoring heuristic based on initial presentation
Correct Answer:
A — Differential diagnosis considering medical etiologies
Rationale:
Ruling out medical causes—such as endocrine disorders, neurological conditions, or
medication effects—is fundamental to psychiatric diagnostic reasoning.
Hypothyroidism commonly presents with depressive symptoms and requires laboratory
evaluation. This represents appropriate differential diagnosis rather than cognitive bias
or premature diagnostic closure.
Question 5
, A PMHNP is formulating a diagnosis for a patient who meets criteria for both
generalized anxiety disorder and major depressive disorder, with neither clearly
predominant. According to DSM-5-TR diagnostic principles, which approach is most
appropriate?
A. Diagnose only the disorder that developed first
B. Diagnose both disorders if full criteria are met for each
C. Assign an unspecified diagnosis to avoid comorbidity
D. Diagnose the more severe disorder and note the other as a rule-out
Correct Answer:
B — Diagnose both disorders if full criteria are met for each
Rationale:
DSM-5-TR permits and encourages multiple diagnoses when full criteria are met for
each condition, as comorbidity is common and clinically meaningful. The temporal
sequence does not determine diagnostic validity, unspecified diagnoses should be
avoided when specific criteria are met, and rule-out status is inappropriate when current
criteria are satisfied.
Question 6
A patient reports that "the government is monitoring my thoughts through the
television." The PMHNP notes the belief is fixed, not culturally normative, and held with
absolute conviction despite contradictory evidence. Which term best describes this
phenomenon?
A. Overvalued idea
B. Delusion
C. Obsession
D. Magical thinking
Correct Answer:
B — Delusion
