Section 1: Psychiatric Diagnosis, Neurocognitive & Personality Disorders
1 A 55-year-old man with poorly controlled diabetes, depression,
neuropathic pain, and poor sleep. Which medication may address all of
these symptoms?
A Amitriptyline — a TCA that treats depression, neuropathic pain, and
insomnia
B Lorazepam — anxiolytic only, no antidepressant or analgesic effect
C Trazodone — primarily for sleep, limited antidepressant and pain efficacy
D Escitalopram — SSRI treats depression but not neuropathic pain
CORRECT ANSWER: A
RATIONALE: Amitriptyline is a tricyclic antidepressant effective for
depression, neuropathic pain, and insomnia — addressing all of this
patient's symptoms. TCAs are first-line for neuropathic pain. SSRIs like
escitalopram treat depression but lack significant analgesic effects.
Trazodone primarily aids sleep.
,2 Jeanne suspects a Christmas card was sent only to check if she gained
weight, worries her husband is cheating without evidence,
counterattacks with anger, and fears confiding in others. Which
disorder best explains her behavior?
A Paranoid personality disorder — pervasive distrust and suspiciousness of
others
B Obsessive compulsive personality disorder
C Schizoid personality disorder
D Schizotypal personality disorder
CORRECT ANSWER: A
RATIONALE: Paranoid personality disorder involves pervasive distrust,
suspicion of others' motives, reluctance to confide, reading hidden
meanings into benign remarks, and quickness to counterattack perceived
insults — all present in Jeanne's presentation. There are no psychotic
features, ruling out schizotypal PD.
3 Betsy simulated a macular rash with cosmetics that was easily wiped
off, with negative ANA. What is the most likely diagnosis?
A Factitious disorder — falsification of physical signs with identified
deception
B Conversion disorder
C Systemic lupus erythematosus
D Illness anxiety disorder
CORRECT ANSWER: A
RATIONALE: Factitious disorder involves deliberate falsification of physical
or psychological symptoms — the removable makeup simulating a rash and
negative ANA confirm deception. Conversion disorder involves neurological
symptoms without conscious falsification. Illness anxiety involves disease
fear without symptom fabrication.
, 4 During a 1-month period, a client meets criteria for schizophrenia. What
else is needed for schizoaffective disorder?
A Major depressive disorder or manic episode occurring concurrently
B Executive dysfunction
C Disorganized speech
D Catatonic behavior
CORRECT ANSWER: A
RATIONALE: Schizoaffective disorder requires meeting criteria for
schizophrenia PLUS a major mood episode (depressive or manic) occurring
concurrently with psychotic symptoms, with psychotic symptoms present
for at least 2 weeks without mood symptoms. Disorganized speech and
catatonic behavior are schizophrenia symptoms.
5 A 72-year-old male with Lewy body dementia had a sleep-wake
disorder in his late 60s. Which sleep disorder did he likely have?
A Rapid eye movement sleep behavior disorder — over 50% develop
neurodegenerative disease
B Non-REM sleep arousal disorder, sleep terror type
C Nightmare disorder
D He likely has all of these
CORRECT ANSWER: A
RATIONALE: REM sleep behavior disorder (RBD) is a prodromal marker for
synucleinopathies — over 50% of individuals with RBD will develop
Parkinson's disease, Lewy body dementia, or multiple system atrophy. It
often precedes cognitive decline by years. Night terrors and nightmares are
not associated with neurodegeneration.
