Exam Questions And Correct
Answers Already Graded A+
**1. A patient with panic disorder shows reduced heart rate variability (HRV). Which
neurotransmitter system is most directly responsible?**
A) Dopamine
B) Norepinephrine
C) GABA
D) Acetylcholine
**Correct Answer: B – Norepinephrine.** Low HRV reflects sympathetic overdrive and
reduced parasympathetic tone, with norepinephrine dysregulation being central in panic
disorder.
**2. Hyperactivity of which brain region is most consistently found in PTSD
hyperarousal?**
A) Hippocampus
B) Prefrontal cortex
C) Amygdala
D) Thalamus
**Correct Answer: C – Amygdala.** Amygdala hyperreactivity to threat cues is the
primary driver of the hyperarousal symptoms seen in PTSD.
**3. A depressed patient has low CSF 5-HIAA. This metabolite comes from which
neurotransmitter?**
A) Dopamine
,B) Serotonin
C) Norepinephrine
D) Epinephrine
**Correct Answer: B – Serotonin.** 5-HIAA (5-hydroxyindoleacetic acid) is the primary
metabolite of serotonin.
**4. HPA axis negative feedback primarily occurs via which mechanism?**
A) CRH on anterior pituitary
B) Cortisol on hippocampus and pituitary
C) ACTH on adrenal cortex
D) DHEA on hypothalamus
**Correct Answer: B – Cortisol on hippocampus and pituitary.** Cortisol exerts negative
feedback on the hypothalamus and pituitary via glucocorticoid receptors, primarily in the
hippocampus.
**5. Which brain structure is the last to fully mature (into mid-20s)?**
A) Amygdala
B) Hippocampus
C) Prefrontal cortex
D) Cerebellum
**Correct Answer: C – Prefrontal cortex.** The prefrontal cortex continues to develop
into the mid-20s and is responsible for executive function, impulse control, and decision-
making.
**6. A patient with atypical depression is most likely to respond well to which
medication?**
A) Atomoxetine
,B) Loxapine
C) Phenelzine
D) Olanzapine
**Correct Answer: C – Phenelzine.** Phenelzine is a Monoamine Oxidase Inhibitor
(MAOI), a class of antidepressants that has been shown to be particularly effective for
atypical depression.
**7. Which of the following describes Methodological Congruence in qualitative
research?**
A) The theory developed from the study is logically consistent and reflective of the data.
B) The researcher presents the philosophical approach and cites references to support
the study's design.
C) The researcher clarifies the significance and applicability of the study.
D) The researcher quotes the participants' statements directly and extensively.
**Correct Answer: B – The researcher presents the philosophical approach and cites
references to support the study's design.** Methodological congruence is about
ensuring that the research methods used are a good fit for the research question and
are supported by a clear philosophical foundation.
**8. In qualitative research, which term describes the researcher's effort to describe the
data gathering process in sufficient detail that the reader can personally experience it?**
A) Methodological Congruence
B) Theoretical Connectedness
C) Analytical Precision
D) Descriptive Vividness
**Correct Answer: D – Descriptive Vividness.** Descriptive vividness is achieved when
the researcher provides such a rich and detailed account of the setting, participants,
and data that the reader feels they were there.
, **9. The decision-making process by which qualitative researchers synthesize concrete
data into an abstract that clarifies the meaning of the study is known as:**
A) Theoretical Connectedness
B) Descriptive Vividness
C) Analytical Precision
D) Heuristic Relevance
**Correct Answer: C – Analytical Precision.** Analytical precision refers to the rigor and
logic of the data analysis process, where the researcher moves from raw data to a
coherent and insightful interpretation.
**10. Which brain structure is activated in patients with severe anxiety as expressed by
the patient?**
A) Hippocampus
B) Amygdala
C) Cingulate gyrus
D) Thalamus
**Correct Answer: B – Amygdala.** The amygdala is the primary brain structure
responsible for processing fear, anxiety, and panic.
**11. A patient with schizophrenia demonstrates auditory hallucinations and
disorganized speech. Which brain region is most implicated?**
A) Frontal lobe
B) Temporal lobe
C) Occipital lobe
D) Parietal lobe
**Correct Answer: B – Temporal lobe.** The temporal lobe houses Wernicke's area
(receptive speech) and is associated with auditory hallucinations in schizophrenia.
