NR606 Week 3 Exam V2 | NR606 Diagnosis & Management in
Psychiatric-Mental Health II Practicum | Q&A with Rationale (NR606
Week 3 Exam) | Chamberlain University
1. According to the DSM-5 criteria for Attention-Deficit/Hyperactivity Disorder (ADHD),
symptoms must be present before what age?
A. Age 7
B. Age 10
C. Age 5
D. Age 12
Answer: D
Explanation: The DSM-5 updated the age of onset criterion from age 7 to age 12. This
change reflects research showing that many individuals who meet full criteria for the
disorder did not necessarily have significant impairment before age 7. Regardless of the
age of onset, symptoms must still be present in two or more settings to meet diagnostic
criteria.
2. A 9-year-old child presents with persistent irritability and frequent episodes of extreme
behavioral dyscontrol that are out of proportion to the situation. Which diagnosis is most
appropriate?
A. Disruptive Mood Dysregulation Disorder (DMDD)
B. Oppositional Defiant Disorder (ODD)
C. Bipolar I Disorder
D. Conduct Disorder
Answer: A
Explanation: DMDD was introduced in the DSM-5 to address concerns about the potential
overdiagnosis of Bipolar Disorder in children. The core feature is chronic, severe persistent
irritability with frequent temper outbursts. Symptoms must be present for at least 12
months in at least two settings to confirm the diagnosis.
3. Which of the following medications is a non-stimulant selective norepinephrine reuptake
inhibitor approved for the treatment of ADHD in children?
A. Methylphenidate
B. Atomoxetine
C. Lisdexamfetamine
,D. Guanfacine
Answer: B
Explanation: Atomoxetine (Strattera) is a selective norepinephrine reuptake inhibitor and
is not a controlled substance. It is an effective alternative for children who do not tolerate
stimulants or have a history of substance abuse. The medication typically takes several
weeks to reach full therapeutic effect compared to the immediate response of stimulants.
4. A PMHNP is treating a 14-year-old for Conduct Disorder. Which of the following behaviors
is a hallmark of this diagnosis?
A. Arguing with authority figures
B. Restlessness and fidgeting
C. Persistent difficulty with sustained attention
D. Serious violations of rules and basic rights of others
Answer: D
Explanation: Conduct Disorder involves a repetitive and persistent pattern of behavior in
which the basic rights of others or major age-appropriate societal norms are violated. This
includes aggression to people and animals, destruction of property, and deceitfulness or
theft. It is considered a more severe diagnosis than Oppositional Defiant Disorder.
5. When prescribing stimulants for ADHD, which physical monitoring parameter is most
critical at each follow-up visit?
A. Height, weight, and blood pressure
B. Liver function tests
C. Serum electrolytes
D. Vision screening
Answer: A
Explanation: Stimulants can cause appetite suppression and potential growth retardation,
necessitating regular monitoring of height and weight. They also have sympathomimetic
effects that can increase heart rate and blood pressure. Providers must track these vitals on
a growth chart to identify significant deviations early in treatment.
6. Which developmental disorder is characterized by persistent deficits in social
communication and social interaction across multiple contexts?
A. Social Anxiety Disorder
B. Intellectual Disability
C. Autism Spectrum Disorder (ASD)
, D. Specific Learning Disorder
Answer: C
Explanation: ASD is defined by social communication deficits and restricted, repetitive
patterns of behavior. These symptoms must be present in the early developmental period
and cause clinically significant impairment. Early intervention is key to improving long-
term functional outcomes for these patients.
7. A 10-year-old child presents with excessive worry about being away from their primary
caregiver, refusing to sleep alone, and somatic complaints on school days. What is the most
likely diagnosis?
A. Generalized Anxiety Disorder
B. Selective Mutism
C. Panic Disorder
D. Separation Anxiety Disorder
Answer: D
Explanation: Separation Anxiety Disorder involves developmentally inappropriate and
excessive fear concerning separation from those to whom the individual is attached.
Common symptoms include reluctance to go out, nightmares about separation, and
physical symptoms like stomachaches when separation is anticipated. Treatment usually
involves Cognitive Behavioral Therapy (CBT) and family involvement.
8. Which FDA-approved medication for pediatric depression carries a black box warning
regarding increased risk of suicidal ideation?
A. Lithium
B. Fluoxetine
C. Bupropion
D. Risperidone
Answer: B
Explanation: Fluoxetine (Prozac) is FDA-approved for the treatment of depression in
children aged 8 and older. The FDA requires a black box warning on all antidepressants for
pediatric use due to the increased risk of suicidal thoughts and behaviors. Close monitoring
of the patient’s mood and behavior is essential during the first few months of therapy.
9. In the treatment of ADHD, what is the primary mechanism of action for alpha-2 adrenergic
agonists like Clonidine and Guanfacine?
A. Blocking dopamine reuptake
B. Increasing serotonin levels
