Section One: Psychiatric Assessment and Diagnostic Principles
Questions 1 through 60
Question 1
A 32-year-old woman presents to the psychiatric clinic with her husband
who reports that over the past three months she has become increasingly
withdrawn, stopped going to work, and has been expressing feelings of
worthlessness and hopelessness. She reports difficulty sleeping, poor
appetite, and a complete loss of interest in activities she previously enjoyed,
including spending time with her children. The husband reports that she
spends most of the day in bed and has had thoughts of wanting to die but
denies a specific plan. Which of the following represents the most
appropriate initial step in the psychiatric assessment of this patient?
A) Conduct a thorough mental status examination and suicide risk
assessment
B) Order a complete blood count and thyroid function tests
C) Begin treatment with a selective serotonin reuptake inhibitor
immediately
D) Refer the patient for cognitive behavioral therapy
Answer: A
Explanation: The patient is presenting with classic symptoms of major
depressive disorder including depressed mood, anhedonia, sleep
disturbances, appetite changes, feelings of worthlessness, and suicidal
ideation. The most appropriate initial step is to conduct a thorough mental
status examination and suicide risk assessment to evaluate the severity of
depression and determine the risk of self-harm. While laboratory testing (B)
may be indicated to rule out organic causes, it should not delay the
psychiatric assessment. Medication (C) and therapy (D) are treatment
interventions that should follow a comprehensive assessment. A complete
psychiatric assessment is essential for accurate diagnosis and treatment
planning.
Question 2
A 45-year-old male is brought to the emergency department by police after
being found wandering in traffic, speaking rapidly and incoherently about
,
being followed by government agents. He is disheveled, appears to have not
bathed for several days, and is observed talking to himself. On examination,
his speech is pressured and difficult to interrupt. He reports that he has not
slept in three days because the government agents are trying to steal his
thoughts and that he has special powers that allow him to read other people's
minds. He is agitated and refuses to stay in the examination room. Which of
the following components of the mental status examination is most critical
to assess in this patient?
A) Insight and judgment
B) Thought content and form
C) Memory and orientation
D) Intelligence and abstract reasoning
Answer: B
Explanation: This patient is presenting with symptoms consistent with acute
psychosis including thought broadcasting (the belief that others can read his
thoughts), paranoid delusions (being followed by government agents),
pressured speech, and agitation. Assessment of thought content and thought
form is the most critical component of the mental status examination in this
case to characterize the nature of the psychotic symptoms. Thought content
includes delusions, obsessions, and suicidal or homicidal ideation. Thought
form includes the organization and coherence of speech. While insight and
judgment (A), memory and orientation (C), and intelligence and abstract
reasoning (D) are important components of a complete mental status
examination, they are less immediately critical than characterizing the
psychotic symptoms which will guide urgent treatment decisions.
Question 3
A 28-year-old woman presents to her primary care provider with a history of
multiple physical complaints over the past two years. She has seen
numerous specialists and undergone multiple diagnostic tests including
endoscopy, colonoscopy, cardiac monitoring, and neurological evaluations.
All test results have been normal, yet she continues to experience abdominal
pain, chest tightness, and fatigue. She becomes visibly frustrated when
discussing the normal test results and insists that something is seriously
wrong. She describes her symptoms as severe and disabling, stating that she
,
has had to quit her job and limit her social activities. The patient appears to
be genuinely distressed and there is no evidence of factitious behavior or
malingering. Which of the following is the most likely diagnosis for this
patient?
A) Illness anxiety disorder
B) Somatic symptom disorder
C) Conversion disorder
D) Malingering
Answer: B
Explanation: This patient meets criteria for somatic symptom disorder,
which is characterized by one or more somatic symptoms that are
distressing and result in significant disruption of daily life, accompanied by
excessive thoughts, feelings, and behaviors related to the symptoms. The
patient has multiple physical complaints that have been investigated without
organic explanation, excessive health-related anxiety, and significant
impairment in daily functioning. Illness anxiety disorder (A) is
characterized by preoccupation with having or acquiring a serious illness in
the absence of significant somatic symptoms. Conversion disorder (C)
involves motor or sensory symptoms that suggest neurological disease.
Malingering (D) is the intentional production of false or grossly exaggerated
physical or psychological symptoms for external gain, which is not
suggested in this presentation.
Question 4
A 55-year-old man is referred for psychiatric evaluation after his wife
reports that he has become increasingly forgetful over the past year. His
wife states that he frequently misplaces items, forgets appointments, repeats
questions, and has difficulty managing the household finances. He has also
had trouble finding the right words during conversations and has gotten lost
while driving in familiar neighborhoods. The patient denies any problems
and becomes defensive when his wife discusses these concerns. He scored
22 out of 30 on the Montreal Cognitive Assessment. Which of the following
is the most appropriate next step in the evaluation of this patient?
A) Reassurance and annual follow-up
B) Immediate referral to a neurologist
