Psychiatric Mental Health Advanced Prep: Master PTSD
Diagnosis and Bipolar Disorder Practice Questions &
Detailed Explanations
Subject: Clinical Psychiatry / Post-Traumatic Stress Disorder (PTSD) and
Bipolar Disorder
Question 1: A 32-year-old patient with a history of sexual trauma presents with hypervigilance,
flashbacks, and avoidant behavior. They also exhibit symptoms of mania, including decreased
need for sleep, pressured speech, and grandiosity, which emerged following an SSRI initiation.
What is the most clinically appropriate interpretation of this clinical presentation?
A) The patient has primary Bipolar I Disorder; the PTSD symptoms are a misdiagnosis.
B) The patient meets criteria for Bipolar Disorder, specifically "Antidepressant-Induced Manic
Episode," which suggests an underlying bipolar diathesis.
C) The patient has "Complex PTSD" (C-PTSD) with dissociative features manifesting as manic-
like symptoms.
D) The mania is likely a secondary reaction to the SSRI and does not require a formal diagnosis
of Bipolar Disorder.
Correct Answer: B) The patient meets criteria for Bipolar Disorder, specifically
"Antidepressant-Induced Manic Episode," which suggests an underlying bipolar diathesis.
Explanation: According to DSM-5-TR, a manic episode induced by antidepressant treatment that
persists beyond the physiological effect of the medication is sufficient for a diagnosis of Bipolar I
Disorder. It indicates that the patient has the underlying biological vulnerability for bipolarity,
regardless of the precipitant.
Question 2: Which of the following neurobiological mechanisms is strongly implicated in both
the pathophysiology of PTSD and the affective dysregulation seen in Bipolar Disorder?
A) Hyper-functioning of the prefrontal cortex resulting in excessive inhibitory control.
B) Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis.
C) Increased levels of hippocampal-derived neurotrophic factor (HDNF) in the amygdala.
D) Selective down-regulation of dopamine D2 receptors in the nucleus accumbens.
Correct Answer: B) Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis.
,Explanation: The HPA axis is central to the stress response. In PTSD, there is often a
paradoxical alteration in HPA axis feedback sensitivity; similarly, bipolar disorder is
characterized by profound HPA axis dysregulation, which is linked to mood cycling and stress-
sensitivity.
Question 3: A patient with Bipolar I Disorder, currently in a depressive episode, reports that their
PTSD symptoms have worsened. Which medication would be considered a first-line choice that
effectively targets both bipolar depression and PTSD-related trauma symptoms?
A) Quetiapine
B) Sertraline
C) Lithium
D) Haloperidol
Correct Answer: A) Quetiapine
Explanation: Quetiapine is FDA-approved for both the depressive phase of bipolar disorder and
bipolar mania. It has also shown efficacy in clinical trials for treating the intrusive symptoms
and hyperarousal associated with PTSD.
Question 4: Regarding the "Kindling Hypothesis" in Bipolar Disorder, how does it relate to the
progression of PTSD symptoms in patients with comorbid conditions?
A) Kindling suggests that stress-induced neuronal sensitization increases the frequency and
severity of both manic episodes and trauma-related flashbacks.
B) Kindling is strictly a physiological mechanism for seizures and has no relevance to
psychological trauma.
C) Kindling implies that early trauma creates a "seizure-like" focus in the amygdala that only
responds to anticonvulsants.
D) Kindling refers to the process by which PTSD symptoms inhibit the manic "kindling" effect
in the brain.
Correct Answer: A) Kindling suggests that stress-induced neuronal sensitization increases
the frequency and severity of both manic episodes and trauma-related flashbacks.
Explanation: The kindling hypothesis posits that repeated episodes (or stressors) make the brain
progressively more sensitive to subsequent stimuli. In comorbid patients, trauma acts as a
significant stressor that can "kindle" both the neurobiological circuits for mood cycling and the
emotional reactivity seen in PTSD.
,Question 5: A 45-year-old patient with Bipolar I Disorder asks about the risk of lithium therapy
in the context of their PTSD-related nightmares. How should the provider address the potential
impact of lithium on sleep architecture?
A) Lithium is known to suppress REM sleep, which may paradoxically reduce the frequency of
trauma-related nightmares.
B) Lithium increases REM latency, which exacerbates PTSD-related intrusive thoughts.
C) Lithium has no effect on sleep architecture or dream content.
D) Lithium causes fragmented NREM sleep, leading to increased nightmare severity.
Correct Answer: A) Lithium is known to suppress REM sleep, which may paradoxically
reduce the frequency of trauma-related nightmares.
Explanation: REM sleep is the stage where most emotionally intense dreaming occurs. By
suppressing REM, lithium can sometimes help reduce the frequency or intensity of trauma-
related nightmares, though clinicians must weigh this against potential side effects.
Question 6: In a patient meeting DSM-5 criteria for PTSD, which of the following symptom
clusters is most likely to be misidentified as a symptom of Bipolar II hypomania?
A) Emotional numbing and detachment.
B) Hyperarousal (e.g., exaggerated startle response).
C) Avoidance of external reminders of the trauma.
D) Negative alterations in cognitions and mood.
Correct Answer: B) Hyperarousal (e.g., exaggerated startle response).
Explanation: Hyperarousal in PTSD, which includes irritability, insomnia, and hypervigilance,
can easily be confused with the psychomotor agitation and decreased need for sleep
characteristic of hypomania.
Question 7: Which of the following is considered the gold-standard psychotherapeutic
intervention for PTSD, and how should its timing be handled in a patient with active, rapid-
cycling Bipolar Disorder?
A) Prolonged Exposure (PE) should be initiated immediately to prevent the stabilization of
trauma memories.
B) Eye Movement Desensitization and Reprocessing (EMDR) should be avoided because it can
trigger a manic episode.
, C) Trauma-focused therapy should be delayed until the patient achieves mood stabilization to
prevent symptom decompensation.
D) Cognitive Processing Therapy (CPT) should only be used if the patient is on a mood
stabilizer.
Correct Answer: C) Trauma-focused therapy should be delayed until the patient achieves
mood stabilization to prevent symptom decompensation.
Explanation: Trauma-focused therapies require the patient to engage with distressing memories.
In an unstable patient (rapid-cycling bipolar), this high level of emotional arousal can trigger or
worsen manic or depressive episodes.
Question 8: A patient with Bipolar Disorder exhibits "cyclothymic" temperaments. When
evaluating for PTSD, which diagnostic challenge is most common?
A) Distinguishing between the inherent mood lability of cyclothymia and the trauma-related
emotional dysregulation.
B) Determining if the trauma occurred during a manic or depressive episode.
C) Proving that the trauma was severe enough to cause PTSD in a cyclothymic patient.
D) Finding a clinician who can diagnose both simultaneously.
Correct Answer: A) Distinguishing between the inherent mood lability of cyclothymia and
the trauma-related emotional dysregulation.
Explanation: Both conditions involve affective instability. In cyclothymia, this is a baseline trait;
in PTSD, it is a reactive state. Disentangling these requires careful longitudinal assessment.
Question 9: Regarding the use of Lamotrigine in patients with Bipolar Disorder and comorbid
PTSD, what is the most significant clinical consideration?
A) Lamotrigine worsens PTSD hyperarousal symptoms.
B) Lamotrigine is effective for bipolar depression and may stabilize the emotional reactivity
associated with PTSD.
C) Lamotrigine is contraindicated in patients with trauma histories.
D) Lamotrigine causes rapid-cycling in PTSD patients.
Correct Answer: B) Lamotrigine is effective for bipolar depression and may stabilize the
emotional reactivity associated with PTSD.
