and Detailed Rationales - Latest Update 2026
Q1: A 72-year-old patient with no prior psychiatric history is brought to the clinic by their
adult child, who reports a sudden onset of confusion, disorganized thinking, and
hallucinations that began three days ago. The patient has a history of hypertension and type 2
diabetes. What is the most appropriate initial action for the PMHNP?
A) Admit the patient for inpatient psychiatric care.
B) Conduct a comprehensive psychiatric and medical evaluation, including a review of
medications and recent lab work.
C) Begin an antipsychotic medication immediately.
D) Recommend the family monitor the patient's symptoms for another week.
Answer: B
Rationale: A sudden onset of confusion and hallucinations in an older adult with no prior
psychiatric history is a hallmark presentation of delirium. The PMHNP must first rule out
underlying medical causes, such as infection, medication side effects, or metabolic imbalances .
This requires a comprehensive evaluation and collaboration with other healthcare professionals.
Promptly prescribing antipsychotics or admitting without investigation would be premature and
potentially dangerous.
Q2: A 16-year-old patient is brought in by their parent for a first psychiatric evaluation. The
patient appears withdrawn and speaks only in short phrases. What is the best initial approach
to establish a therapeutic alliance and complete a risk assessment?
A) Interview the parent privately to get the full history, then interview the patient.
B) Interview the patient and parent together to allow the parent to provide information as
needed.
C) Interview the patient alone first, then with the parent to discuss safety concerns.
D) Conduct a full psychiatric evaluation with the patient, and schedule a separate collateral
interview with the parent.
Answer: C
,Rationale: For adolescents, it is a best practice to establish a therapeutic alliance by interviewing
the patient privately to build rapport and allow for open disclosure. This should be followed by
including the parent or guardian for the safety planning and collateral history . Conducting a
comprehensive risk assessment, including suicide risk, is a core component of the "Assess"
domain .
Q3: A PMHNP is evaluating a patient for possible attention-deficit/hyperactivity disorder.
Which of the following is a key component of a targeted psychiatric assessment for this
patient?
A) Ordering a genetic test to assess medication metabolism.
B) A comprehensive review of the patient's developmental history, with input from family
members or teachers where appropriate.
C) A full neurological examination to rule out structural brain abnormalities.
D) A trial of a non-stimulant medication to assess the patient's response.
Answer: B
Rationale: Diagnosis of neurodevelopmental disorders relies heavily on the history of symptoms
and functional impairment across settings. The PMHNP must gather collateral information from
family, teachers, and other relevant sources as part of a comprehensive psychiatric evaluation .
Q4: A PMHNP is assessing a patient's "readiness for change." Which theoretical model is most
directly applicable to this assessment?
A) The Health Belief Model.
B) The Transtheoretical Model (Stages of Change).
C) Maslow's Hierarchy of Needs.
D) Piaget's Theory of Cognitive Development.
Answer: B
Rationale: Assessing readiness for change is a key task in the "Assess" domain . The
Transtheoretical Model (Stages of Change: precontemplation, contemplation, preparation,
action, maintenance) is the framework most directly used to understand a patient's motivation
and tailor the plan of care .
,Q5: A patient being assessed for depression reveals that they have been experiencing
frequent suicidal thoughts but has no plan or intent. What is the PMHNP's immediate
priority?
A) Start the patient on a selective serotonin reuptake inhibitor (SSRI) immediately.
B) Conduct a comprehensive risk assessment, ensure a safety plan, and provide a crisis contact
number.
C) Admit the patient to an inpatient psychiatric unit for their safety.
D) Tell the patient to call a family member to stay with them.
Answer: B
Rationale: Risk assessment and safety planning are essential components of the "Assess"
domain . The priority is to systematically evaluate the risk, collaborate with the patient on a
safety plan, and provide immediate resources such as a crisis hotline or contact. Hospitalization
is only indicated if the risk is imminent.
Domain II: Diagnose (28 Questions)
Q6: A patient presents with a two-week history of low mood, anhedonia, fatigue, poor
concentration, and insomnia. The patient also reports they have been drinking at least four
beers a night to help them sleep. What is the most appropriate diagnostic consideration?
A) Major Depressive Disorder, single episode.
B) Alcohol Use Disorder.
C) Both Major Depressive Disorder and Alcohol Use Disorder.
D) Adjustment Disorder with depressed mood.
Answer: C
Rationale: The patient meets criteria for a major depressive episode. The criteria for an alcohol
use disorder must also be assessed. PMHNPs must be able to formulate differential diagnoses
and identify comorbid psychiatric and medical conditions . It is crucial to establish a primary
diagnosis and any relevant secondary or tertiary diagnoses rather than attributing all symptoms
to one cause.
Q7: A 24-year-old college student is referred by their primary care provider for an evaluation
for "possible ADHD." The patient reports significant difficulty concentrating during lectures
but can hyperfocus on video games for hours. What is the most important step for the
PMHNP to take?
, A) Prescribe a trial of a stimulant medication.
B) Conduct a comprehensive psychiatric evaluation to rule out other conditions like anxiety or
depression.
C) Recommend academic accommodations based on the patient's self-report.
D) Order a neuropsychological test before proceeding.
Answer: B
Rationale: The PMHNP must interpret information to formulate differential diagnoses .
Symptoms of inattention are non-specific and can be caused by anxiety, depression, substance
use, or sleep disorders. A comprehensive diagnostic evaluation is necessary to establish the
correct diagnosis and prioritize potential diagnoses before implementing a plan .
Q8: A patient who experienced a traumatic event two months ago reports persistent
nightmares, hypervigilance, an exaggerated startle response, and avoidance of anything that
reminds them of the event. They also describe feeling a sense of emotional detachment from
others. What is the most likely diagnosis?
A) Acute Stress Disorder.
B) Posttraumatic Stress Disorder (PTSD).
C) Adjustment Disorder.
D) Generalized Anxiety Disorder.
Answer: B
Rationale: The patient's symptoms (re-experiencing, avoidance, negative alterations in
cognition/mood, and arousal/reactivity) are characteristic of PTSD. The criterion for PTSD
requires that symptoms persist for more than one month .
Q9: A PMHNP is evaluating a 40-year-old patient who has been brought in by their spouse.
The spouse reports the patient has had "three episodes" in the past five years of "going
crazy," characterized by decreased need for sleep, grandiosity, impulsive spending, and rapid
speech. The patient currently denies any problem and states they "feel great." What is the
most appropriate diagnosis?
A) Schizophrenia.
B) Bipolar I Disorder, most recent episode manic.
C) Bipolar II Disorder, current hypomanic episode.
D) Cyclothymic Disorder.
