NR606 Week 5 Exam V3 | NR606 Diagnosis & Management in
Psychiatric-Mental Health II Practicum | Q&A with Rationale (NR606
Week 5 Exam) | Chamberlain University
1. When evaluating a 7-year-old child for Attention-Deficit/Hyperactivity Disorder (ADHD),
which of the following is the most critical diagnostic requirement according to the DSM-5-TR?
A. Symptoms must have been present since birth.
B. A positive response to a trial of stimulant medication.
C. Symptoms must be present in at least two or more settings.
D. The child must exhibit symptoms of both inattention and hyperactivity.
Answer: C
Explanation: The DSM-5-TR specifies that for a diagnosis of ADHD, several symptoms
must be present in two or more settings, such as home and school. This ensures that the
impairment is pervasive and not restricted to a single environment or interpersonal
relationship. Requiring evidence across settings increases the diagnostic validity of the
condition.
2. A 15-year-old female presents with symptoms of Major Depressive Disorder (MDD). Which
FDA-approved medication is typically the first-line choice for treating depression in this age
group?
A. Paroxetine (Paxil)
B. Venlafaxine (Effexor)
C. Fluoxetine (Prozac)
D. Amitriptyline (Elavil)
Answer: C
Explanation: Fluoxetine is one of the few medications specifically FDA-approved for the
treatment of Major Depressive Disorder in children and adolescents aged 8 and older.
While other SSRIs are used off-label, Fluoxetine has the strongest evidence base for efficacy
and safety in this population. It is critical to monitor for the black box warning regarding
increased suicidal ideation when initiating therapy.
3. Which of the following describes the ‘Tarasoff Rule’ that guides the practice of Psychiatric-
Mental Health Nurse Practitioners (PMHNPs)?
A. The duty to protect the patient’s privacy at all costs.
B. The duty to warn a third party if a patient poses a serious threat of harm.
,C. The requirement to obtain informed consent for all psychiatric procedures.
D. The mandate to report all suspected cases of child abuse to authorities.
Answer: B
Explanation: The Tarasoff Rule establishes the legal obligation of mental health
professionals to protect potential victims from a patient’s violent threats. This duty may
involve warning the intended victim, notifying the police, or taking other necessary steps. It
represents a significant exception to the standard rules of patient confidentiality.
4. A child presents with a pattern of angry/irritable mood, argumentative behavior, and
vindictiveness lasting at least 6 months. Which diagnosis is most likely?
A. Oppositional Defiant Disorder (ODD)
B. Conduct Disorder
C. Disruptive Mood Dysregulation Disorder (DMDD)
D. Intermittent Explosive Disorder
Answer: A
Explanation: Oppositional Defiant Disorder (ODD) is characterized by a persistent pattern
of angry mood and defiance toward authority figures. Unlike Conduct Disorder, ODD does
not typically involve the violation of the basic rights of others or major age-appropriate
societal norms. The duration of at least 6 months is a core diagnostic criterion for ODD.
5. Which clinical feature distinguishes Disruptive Mood Dysregulation Disorder (DMDD) from
Bipolar Disorder in children?
A. DMDD is characterized by chronic, persistent irritability between outbursts.
B. DMDD requires the presence of distinct manic episodes.
C. Bipolar Disorder is only diagnosed if symptoms start before age 10.
D. There is no significant clinical difference between the two.
Answer: A
Explanation: DMDD was introduced in the DSM-5 to address concerns about the
overdiagnosis of Bipolar Disorder in children. The hallmark of DMDD is chronic, non-
episodic irritability and frequent temper outbursts, whereas Bipolar Disorder requires
distinct periods of mania or hypomania. Children with DMDD are actually at higher risk for
developing unipolar depression or anxiety disorders later in life, rather than Bipolar
Disorder.
6. What is the primary mechanism of action for stimulant medications like Methylphenidate
in the treatment of ADHD?
A. Antagonizing NMDA receptors in the prefrontal cortex.
, B. Increasing the levels of serotonin in the synaptic cleft.
C. Blocking the reuptake of dopamine and norepinephrine.
D. Modulating GABAergic transmission in the basal ganglia.
Answer: C
Explanation: Stimulants function by increasing the availability of dopamine and
norepinephrine in the prefrontal cortex and basal ganglia. Methylphenidate specifically
inhibits the reuptake of these neurotransmitters, thereby improving focus and executive
function. This mechanism helps compensate for the hypoarousal often seen in ADHD
neurobiology.
7. In the treatment of pediatric anxiety, which psychotherapy modality is considered the ‘gold
standard’?
A. Dialectical Behavior Therapy (DBT)
B. Cognitive Behavioral Therapy (CBT)
C. Psychoanalytic Therapy
D. Gestalt Therapy
Answer: B
Explanation: Cognitive Behavioral Therapy (CBT) is highly effective for pediatric anxiety,
focusing on identifying maladaptive thoughts and using exposure-based techniques. It has
the most robust evidence base for improving symptoms across various anxiety disorders in
youth. CBT helps children develop coping strategies to manage their physiological and
cognitive responses to stressors.
8. Which laboratory test is essential to monitor when a patient is prescribed a second-
generation antipsychotic (SGA)?
A. Lipid profile and fasting blood glucose
B. Renal function tests (BUN/Creatinine)
C. Chest X-ray
D. Serum electrolytes
Answer: A
Explanation: Second-generation antipsychotics are associated with metabolic side effects,
including weight gain, dyslipidemia, and insulin resistance. Monitoring fasting blood
glucose and a lipid profile is crucial for the early detection of metabolic syndrome. These
screenings should be performed at baseline and at regular intervals during treatment.
