Section I — Foundations of Differential Diagnosis
Question 1
A psychiatric mental health nurse practitioner evaluates a patient presenting with depressed
mood, fatigue, poor concentration, and insomnia. Which component of the assessment is most
important before assigning a primary psychiatric diagnosis?
A. The patient's preferred treatment
B. A comprehensive history and mental status examination
C. The patient's family preference
D. The patient's insurance coverage
Correct Answer: B. A comprehensive history and mental status examination
Rationale:
Psychiatric diagnosis requires integration of the patient's history, current symptoms, functional
impairment, mental status examination, medical history, medications, substance use, and
psychosocial context. A symptom such as fatigue or insomnia can occur in depression, anxiety,
substance use, medical illness, medication effects, and sleep disorders. A comprehensive
assessment helps distinguish among these possibilities rather than prematurely assigning a
psychiatric diagnosis.
Question 2
Which finding most strongly suggests that a psychiatric symptom may have a medical or
substance-induced cause?
A. Symptoms began after a major interpersonal conflict
B. Symptoms have occurred intermittently since adolescence
C. Symptoms began abruptly after initiation of a new medication
D. Symptoms improve with psychotherapy
Correct Answer: C. Symptoms began abruptly after initiation of a new medication
Rationale:
A close temporal relationship between a new medication and the onset of psychiatric symptoms
,raises concern for a medication-induced condition. The clinician should review prescribed
medications, over-the-counter products, supplements, alcohol, caffeine, and illicit substances.
Temporal relationships are particularly important when symptoms represent a significant change
from the patient's baseline.
Question 3
A patient reports hearing voices. Which question is most clinically useful during the initial
evaluation?
A. "Do you believe your voices are real?"
B. "What are the voices saying, and are they telling you to harm yourself or someone else?"
C. "Have you always heard voices?"
D. "Why do you think you hear voices?"
Correct Answer: B. "What are the voices saying, and are they telling you to harm yourself
or someone else?"
Rationale:
When hallucinations are present, the clinician must immediately assess content, frequency,
command quality, associated distress, and potential risk. Command hallucinations involving
suicide or violence require careful safety assessment. Determining whether the patient recognizes
the experience as unusual is also important, but immediate safety takes priority.
Question 4
Which feature best distinguishes a symptom from a psychiatric disorder?
A. The symptom is unusual
B. The symptom causes clinically significant distress or impairment
C. The symptom occurs in adulthood
D. The symptom requires medication
Correct Answer: B. The symptom causes clinically significant distress or impairment
Rationale:
Psychiatric diagnosis generally depends not merely on the presence of a symptom but on its
severity, persistence, context, and impact on functioning. Cultural norms and developmental
expectations must also be considered. An isolated behavior that causes no meaningful
impairment may not constitute a mental disorder.
, Question 5
A clinician wants to determine whether anxiety symptoms are secondary to hyperthyroidism.
Which approach is most appropriate?
A. Diagnose generalized anxiety disorder immediately
B. Ignore physical symptoms
C. Obtain an appropriate medical evaluation while continuing psychiatric assessment
D. Start an antipsychotic medication
Correct Answer: C. Obtain an appropriate medical evaluation while continuing psychiatric
assessment
Rationale:
Medical disorders can produce symptoms that resemble psychiatric conditions. Hyperthyroidism,
for example, may cause anxiety, irritability, insomnia, tremor, and palpitations. A differential
diagnosis should therefore consider medical causes rather than assuming that all psychological
symptoms represent a primary psychiatric disorder.
Question 6
Which element is particularly important when assessing psychiatric symptoms in children and
adolescents?
A. Comparing the patient only with adults
B. Developmental stage and age-appropriate functioning
C. Ignoring school performance
D. Using adult diagnostic criteria without modification
Correct Answer: B. Developmental stage and age-appropriate functioning
Rationale:
Psychiatric symptoms must be interpreted within the patient's developmental context. Behavior
that is normal at one developmental stage may be concerning at another. Information from
parents, caregivers, teachers, and school records may be necessary because children and
adolescents may have limited insight or difficulty describing symptoms.
Question 7
A patient denies suicidal ideation but recently gave away valued possessions and wrote a
farewell letter. What is the best interpretation?
