NR547 Exam 4 V1 Questions with Correct Answers
1. According to the DSM-5-TR, at what age must several inattentive or hyperactive-
impulsive symptoms be present for a diagnosis of ADHD?
A. Before age 7
B. Before age 15
C. Before age 12
D. Before age 18
Correct Answer: C
Expert Explanation: The DSM-5-TR specifies that several inattentive or
hyperactive-impulsive symptoms must be present before the age of 12. This
criterion ensures that the neurodevelopmental patterns started during childhood
rather than later in life. Other options like age 7 were used in previous versions of
the manual but have since been updated to provide a broader window for clinical
assessment.
2. Which of the following is a core clinical feature required for the diagnosis of Autism
Spectrum Disorder (ASD)?
A. Intellectual disability and low IQ scores
B. Inattentiveness in academic settings
,C. History of physical abuse or neglect
D. Deficits in social-emotional reciprocity
Correct Answer: D
Expert Explanation: Deficits in social-emotional reciprocity represent a core
diagnostic criterion for ASD under the social communication domain. Patients with
ASD often struggle with back-and-forth conversation and sharing of interests or
emotions. While intellectual disability can co-occur with ASD, it is not a required
feature for the diagnosis itself.
3. To diagnose PTSD, symptoms must persist for at least how long after the traumatic
event?
A. More than 1 month
B. More than 1 week
C. More than 6 months
D. More than 1 year
Correct Answer: A
Expert Explanation: PTSD requires that the duration of symptoms be more than
one month following exposure to a traumatic event. If the symptoms last for less
than one month but at least three days, the diagnosis is typically Acute Stress
,Disorder. This timeframe is crucial for distinguishing between temporary stress
reactions and a chronic psychological disorder.
4. Which clinical feature primarily distinguishes Anorexia Nervosa (Restricting Type)
from Bulimia Nervosa?
A. Excessive exercise to lose weight
B. Frequent binge eating episodes
C. Significantly low body weight
D. Self-induced vomiting after meals
Correct Answer: C
Expert Explanation: The primary clinical distinction is that individuals with
Anorexia Nervosa maintain a significantly low body weight relative to their age and
height. In contrast, individuals with Bulimia Nervosa are typically within or above
the normal weight range. While both disorders involve body image distortion,
weight status is the defining diagnostic separator between these two conditions.
5. A patient presents with tremors, tachycardia, and auditory hallucinations 48 hours
after their last drink. What is the most likely diagnosis?
A. Alcohol Withdrawal
B. Stimulant Intoxication
, C. Opioid Withdrawal
D. Cannabis Use Disorder
Correct Answer: A
Expert Explanation: The presentation of tremors, tachycardia, and hallucinations
shortly after cessation of drinking is characteristic of Alcohol Withdrawal. These
symptoms typically emerge within 6 to 48 hours and can progress to more severe
states like Delirium Tremens. Monitoring vital signs and using the CIWA scale are
essential steps in managing this potentially life-threatening condition.
6. What is the minimum duration of symptoms required for a diagnosis of Generalized
Anxiety Disorder (GAD)?
A. 2 weeks
B. 1 month
C. 3 months
D. 6 months
