, SECTION 1: Psychiatric Assessment & Interview
Q1. A 42-year-old patient arrives for an initial psychiatric evaluation accompanied by a spouse who answers most
questions directed at the patient. The PMHNP notes that the patient appears withdrawn and frequently looks to the
spouse before speaking. To obtain the most reliable psychiatric history while preserving the therapeutic alliance, the
clinician should first:
A. Conduct the entire interview with the spouse present to ensure accuracy of collateral data
B. Document the spouse as the primary historian and proceed without further adjustment
C. Politely request a period of private interview time with the patient after obtaining initial identifying data
D. Postpone the assessment until the patient can attend alone at a later appointment
Correct Answer: C
Rationale: Best practice in psychiatric assessment balances the value of collateral information with the need for a private patient interview.
Requesting private time after initial data collection allows the clinician to assess the patient's independent report, evaluate interpersonal
dynamics, and protect confidentiality while still incorporating collateral data later.
Q2. During the chief complaint portion of a psychiatric interview, a patient states, "I just can't sleep and everything feels
heavy." The PMHNP follows with open-ended exploration of the symptom timeline, associated features, and functional
impact. This approach primarily serves to:
A. Rapidly narrow the differential to a single DSM-5 diagnosis
B. Establish whether the patient meets criteria for involuntary commitment
C. Elicit a detailed present illness history that supports formulation and differential diagnosis
D. Replace the need for a formal mental status examination
Correct Answer: C
Rationale: Open-ended exploration of the chief complaint builds the history of present illness, including onset, duration, severity, associated
symptoms, and functional impact. This narrative data is essential for accurate differential diagnosis and clinical formulation rather than
premature diagnostic closure.
Q3. A PMHNP is reviewing the past psychiatric history of a patient with recurrent major depressive episodes. The
patient reports three prior hospitalizations but cannot recall medication names or approximate dates. The most
appropriate next step to strengthen the historical database is to:
A. Rely solely on the patient's current self-report for treatment planning
B. Request records from prior treatment facilities and pharmacies with appropriate releases
C. Assume all prior episodes were identical to the current presentation
D. Limit the assessment to the current episode only to avoid confusion
Correct Answer: B
Rationale: When patient recall of past treatment is incomplete, obtaining prior records (with consent) provides critical information about
medication trials, response, adverse effects, and course. This improves diagnostic accuracy and reduces the risk of repeating ineffective or
harmful interventions.
Q4. In conducting a comprehensive psychiatric assessment, the PMHNP systematically inquires about substance use,
including alcohol, cannabis, stimulants, opioids, and prescription misuse. This inquiry is essential because:
A. Substance use disorders are rare comorbidities in psychiatric populations
B. Only patients who volunteer substance use history need formal screening
C. Substance-induced symptoms can closely mimic primary psychiatric disorders and alter treatment response
D. Laboratory testing alone is sufficient to rule out substance-related contributions
Correct Answer: C
Rationale: Substance use can produce or exacerbate nearly every major psychiatric syndrome. Systematic screening is required because
patients may not spontaneously disclose use, and unidentified substance effects can lead to misdiagnosis and inappropriate treatment
selection.
