NRNP 6635 Midterm Exam – Questions 1–50
QUESTION 1
Select the neurotransmitter involved in obsessive-compulsive disorder (OCD) in
children and adolescents, especially with tic disorder comorbidity.
A. Norepinephrine
B. GABA
C. Dopamine
D. Acetylcholine
Rationale:
OCD is associated with dysfunction in the cortico-striatal-thalamic-cortical circuitry.
Dopamine plays a key role in the reward system, and dysregulation can lead to
repetitive compulsive behaviors. While serotonin is also involved in OCD, the presence
of tics points more specifically to dopaminergic involvement.
References: Pittenger et al., 2016; Richter et al., 2019
QUESTION 2
Select the class of drugs most effective in treating pain disorder.
,A. Antidepressants
B. Opioid analgesics
C. Beta-adrenergic blockers
D. Mood stabilizers
Rationale:
Antidepressants, particularly tricyclic antidepressants (TCAs) and serotonin-
norepinephrine reuptake inhibitors (SNRIs), are effective in treating chronic pain
disorders. They modulate pain perception in the central nervous system and improve
coexisting depressive symptoms, which can exacerbate pain. Opioids are reserved for
acute or severe pain but are not first-line for chronic pain disorders.
References: Andrieu et al., 2017; Mangione & Crowley-Matoka, 2018
QUESTION 3
Select the most commonly occurring eating disorder.
A. Anorexia nervosa
B. Bulimia nervosa
C. Purging disorder
D. Binge eating disorder
Rationale:
Binge eating disorder (BED) is more prevalent than anorexia and bulimia, particularly
among adolescents and adults. It involves recurrent episodes of eating large amounts
of food with loss of control, often without compensatory behaviors like purging. BED is
strongly associated with obesity, depression, and metabolic syndrome.
QUESTION 4
Select the disorder in which inflicting injury to self or others is common.
A. Pain disorder
B. Conversion disorder
, C. Somatic symptom disorder
D. Factitious disorder
Rationale:
Factitious disorder involves intentionally producing or feigning physical or
psychological symptoms to assume the sick role. This can include self-inflicted injury
or falsifying symptoms. Patients may go to extreme lengths to appear ill, even
undergoing invasive procedures.
QUESTION 5
Select two imaging methods commonly used to study anxiety disorders.
A. CT
B. TMS
C. MRI
D. EKG
Rationale:
MRI and functional MRI (fMRI) are frequently used in anxiety disorder research to
assess structural and functional abnormalities in the amygdala, prefrontal cortex, and
hippocampus. CT is less sensitive to subtle brain changes. TMS and EKG are not
primary diagnostic tools for imaging anxiety disorders.
QUESTION 6
Select the two factors that do not cause dissociative amnesia.
A. Sexual abuse
B. Substance abuse
C. Surgical pain
D. Partner betrayal
Rationale:
Dissociative amnesia is typically caused by trauma or stress affecting memory
integration. While substance abuse and surgical pain can trigger dissociative amnesia
