Question 1
A 28-year-old female with a history of PTSD presents with flashbacks,
hypervigilance, and nightmares. She reports using alcohol to help her sleep.
What is the most appropriate first-line pharmacologic intervention for her
trauma-related nightmares?
A. Quetiapine 25 mg at bedtime
B. Prazosin 1 mg at bedtime
C. Trazodone 50 mg at bedtime
D. Hydroxyzine 25 mg at bedtime
Correct Answer: B. Prazosin 1 mg at bedtime
Rationale: Prazosin is an alpha-1 antagonist with robust evidence for
reducing trauma-related nightmares in PTSD. It is the guideline-supported
first-line agent specifically for PTSD-associated nightmares. While trazodone
and quetiapine are used for sleep, they are not first-line for this specific
indication. Hydroxyzine is an antihistamine used for anxiety but lacks
evidence for PTSD nightmares .
,Question 2
A PMHNP is reviewing a patient's chart and notes the phrase "blunted
affect." Which clinical presentation best correlates with this documentation?
A. A complete lack of emotional expression
B. A wide range of emotional expression with rapid shifts
C. A significant reduction in the intensity of emotional expression
D. Emotional expression that is incongruent with the situation
Correct Answer: C. A significant reduction in the intensity of emotional
expression
Rationale: Blunted affect refers to a marked reduction in the intensity of
emotional expression. Flat affect is the complete absence of emotional
expression (option A). Labile affect refers to rapid shifts in emotion (option B),
and inappropriate affect is incongruent with the content of discussion (option
D) .
Question 3
A 45-year-old male with major depressive disorder (MDD) has been on
fluoxetine 40 mg for 8 weeks with partial response. He reports anorgasmia.
What is the best next step?
A. Switch to sertraline
B. Increase fluoxetine to 60 mg
C. Add bupropion 150 mg daily
D. Discontinue fluoxetine and start mirtazapine
Correct Answer: C. Add bupropion 150 mg daily
,Rationale: Bupropion is often added to SSRIs to counteract sexual side effects
like anorgasmia. Switching to another SSRI (like sertraline) may not resolve
the issue, as sexual dysfunction is a class effect. Increasing the dose would
likely worsen the side effect. While mirtazapine has fewer sexual side effects,
adding bupropion is a first-line strategy for managing SSRI-induced sexual
dysfunction .
Question 4
According to Barkley DRT standards, which of the following is a critical
element in the "Assessment" section of a psychiatric note?
A. The patient's vital signs
B. A detailed list of all medications with dosages
C. A formulation integrating biopsychosocial factors and a differential
diagnosis
D. The exact start and stop times of the previous therapy session
Correct Answer: C. A formulation integrating biopsychosocial factors
and a differential diagnosis
Rationale: The Assessment section must include a clinical formulation,
differential diagnoses, and a synthesis of the data. Vital signs and medication
lists belong in the objective or plan sections. Therapy start/stop times are not
a required critical element for establishing medical necessity .
Question 5
, A patient with bipolar I disorder is stabilized on lithium 900 mg/day. Their
current lithium level is 1.2 mEq/L. They present with coarse tremor, nausea,
and confusion. What is the priority intervention?
A. Increase lithium to 1200 mg/day
B. Add propranolol for tremor
C. Hold lithium and assess renal function
D. Add ondansetron for nausea
Correct Answer: C. Hold lithium and assess renal function
Rationale: The symptoms (coarse tremor, nausea, confusion) with a level of
1.2 mEq/L indicate early lithium toxicity, especially if the patient is
dehydrated or has renal impairment. Lithium should be held, and renal
function and level should be rechecked immediately. Increasing the dose
would worsen toxicity. Propranolol may be used for benign tremor at
therapeutic levels but is not appropriate in this toxic state .
Question 6
Which of the following best describes the concept of "medical necessity" as
required for insurance reimbursement in psychiatric practice?
A. The treatment is convenient for the patient's schedule
B. The treatment is intended to prevent, diagnose, or treat a condition that
leads to significant impairment in functioning
C. The treatment is requested by the patient's family
D. The treatment is the most expensive option available to ensure quality
Correct Answer: B. The treatment is intended to prevent, diagnose, or
treat a condition that leads to significant impairment in functioning
Rationale: Medical necessity requires that services are essential for the
diagnosis or treatment of a condition causing functional impairment.
