1. A 78-year-old male patient with a history of hypertension and type 2 diabetes presents
with a complaint of progressive difficulty with short-term memory over the past six
months. His family reports he has become withdrawn and occasionally agitated. His
MMSE score is 22/30. What is the most appropriate initial assessment tool to
differentiate between normal aging and Mild Neurocognitive Disorder?
A. Geriatric Depression Scale
B. Montreal Cognitive Assessment
C. Clock Drawing Test
D. Mini-Cog
════════════════════
Correct Answer: B. Montreal Cognitive Assessment
Rationale: The Montreal Cognitive Assessment (MoCA) is more sensitive than the MMSE
for detecting mild cognitive impairment (MCI). A score of 22/30 on the MMSE is within the
range that could be interpreted as normal for some but may also be indicative of early
cognitive decline. The MoCA provides a more comprehensive assessment of executive
function and visuospatial abilities, which are often the first domains affected in MCI. The
Geriatric Depression Scale is a screening tool for depression, which can mimic dementia
but is not the primary assessment for Neurocognitive Disorder. The Clock Drawing Test
and Mini-Cog are useful bedside screens but lack the granularity to differentiate normal
aging from MCI as effectively as the MoCA, which is specifically validated for this purpose.

2. In the context of therapeutic communication with a patient who has a diagnosis of
schizophrenia and is experiencing auditory hallucinations, which of the following
responses by the PMHNP best demonstrates a focus on reality orientation and
validation?
A. "I know the voices are scary, but they are not real. They are a symptom of your
illness."
B. "I don't hear the voices, but I can understand how frightening this experience is for
you."
C. "Tell me more about what the voices are saying to you right now."
D. "Have you tried telling the voices to go away?"
, ════════════════════
Correct Answer: B. "I don't hear the voices, but I can understand how frightening this
experience is for you."
Rationale: This response provides a reality check without challenging the patient's
experience. It validates the patient's emotional state (fear) while gently grounding the
interaction in reality by stating that the nurse does not share the hallucination. This
reduces the likelihood of increasing the patient's anxiety or paranoia. Option A denies the
patient's subjective reality and can be perceived as confrontational. Option C reinforces
the hallucination by encouraging the patient to elaborate on its content. Option D
dismisses the experience and provides a simplistic, ineffective solution that may frustrate
the patient.
════════════════════
3. A 45-year-old female patient with Major Depressive Disorder has been on Fluoxetine 40
mg daily for 8 weeks with partial improvement. She complains of continued anhedonia
and low energy. The PMHNP decides to add Bupropion to augment the antidepressant
effect. What is the primary rationale for this combination?
A. Bupropion is a potent inhibitor of CYP2D6, increasing fluoxetine levels.
B. Bupropion's effect on norepinephrine and dopamine reuptake addresses residual
symptoms of anhedonia and fatigue.
C. Bupropion blocks the serotonin reuptake transporter, providing a synergistic
serotonergic effect.
D. Bupropion has a higher affinity for the 5-HT2A receptor, reducing the sexual side
effects of fluoxetine.
════════════════════
Correct Answer: B. Bupropion's effect on norepinephrine and dopamine reuptake
addresses residual symptoms of anhedonia and fatigue.
Rationale: Bupropion is a norepinephrine-dopamine reuptake inhibitor (NDRI). Its
dopaminergic action is thought to be particularly beneficial for symptoms of anhedonia
(lack of pleasure) and fatigue, which are often resistant to SSRI monotherapy. This makes
it a logical augmenting agent. Option A is incorrect because bupropion is a substrate of
CYP2D6, not an inhibitor. Option C is incorrect as bupropion does not act on the serotonin
transporter. Option D is incorrect because bupropion has negligible affinity for serotonin
receptors.
════════════════════
,4. Which of the following ethical principles is most directly challenged when a PMHNP is
considering the use of involuntary psychiatric commitment for a patient who is actively
suicidal but refuses treatment?
A. Beneficence
B. Autonomy
C. Justice
D. Nonmaleficence
════════════════════
Correct Answer: B. Autonomy
Rationale: Autonomy is the principle of self-determination and the right of an individual
to make their own decisions regarding their healthcare. Involuntary commitment directly
overrides a patient's autonomous decision to refuse treatment. While the principles of
beneficence (doing good) and nonmaleficence (doing no harm) are also relevant in
justifying the commitment (to prevent harm and save the patient's life), the core ethical
conflict is between the patient's autonomy and the provider's duty to protect them. Justice
(fair and equitable distribution of resources) is less directly implicated in this individual
clinical scenario.
════════════════════
5. A patient presents with symptoms of anxiety, palpitations, and shortness of breath.
Upon assessment, they report that these symptoms occur sporadically and peak within
10 minutes. The patient expresses a persistent fear of having another attack and has
started avoiding places where attacks have previously occurred. Which diagnosis is most
consistent with this clinical picture?
A. Generalized Anxiety Disorder
B. Social Anxiety Disorder
C. Panic Disorder
D. Specific Phobia
════════════════════
Correct Answer: C. Panic Disorder
Rationale: The clinical picture of recurrent, unexpected panic attacks (sporadic symptoms
peaking rapidly) accompanied by persistent worry about future attacks and maladaptive
behavioral changes (avoidance) is the hallmark of Panic Disorder. Generalized Anxiety
Disorder is characterized by chronic, excessive worry over multiple domains. Social Anxiety
Disorder is characterized by a persistent fear of social or performance situations. Specific
Phobia involves a marked fear of a specific object or situation. The key differentiator here
, is the recurrent nature of the panic attacks themselves and the subsequent behavioral
changes.
════════════════════
6. A 16-year-old adolescent is brought to the clinic by her parents due to concerns about
her rapidly declining academic performance, severe mood swings, and increased conflict
at home. The patient reports feeling "down" most of the time but also has episodes of
intense irritability and impulsivity. She admits to occasional heavy alcohol use on
weekends. What is the most critical initial step in the psychiatric evaluation of this
adolescent?
A. Administer a urine drug screen.
B. Perform a comprehensive risk assessment for suicide and self-harm.
C. Obtain a detailed family history of mood disorders.
D. Discuss the potential need for a psychoeducational assessment.
════════════════════
Correct Answer: B. Perform a comprehensive risk assessment for suicide and self-harm.
Rationale: The most critical and immediate priority in any psychiatric evaluation,
especially in an adolescent presenting with mood symptoms, impulsivity, and substance
use, is to assess for safety. A comprehensive risk assessment for suicide, self-harm, and
harm to others must be conducted to determine the acuity of the situation. While the
other options are important components of a thorough evaluation, they are not the initial,
non-negotiable step. Ensuring patient safety is the foremost clinical responsibility.

7. A 35-year-old male with a history of alcohol use disorder is in the acute detoxification
phase. He is receiving a Chlordiazepoxide protocol. Which assessment finding would be
the most significant indicator of impending alcohol withdrawal delirium (Delirium
Tremens)?
A. Mild diaphoresis and tachycardia.
B. Coarse tremor of the hands.
C. Disorientation to place and time with vivid visual hallucinations.
D. Nausea and vomiting.
════════════════════
Correct Answer: C. Disorientation to place and time with vivid visual hallucinations.
Rationale: Delirium Tremens (DTs) is a severe manifestation of alcohol withdrawal
characterized by a global confusional state, marked autonomic hyperactivity, and
