NR 546 Week 4 Midterm Exam — Questions with Rationales
10-Point Exam Coverage Summary
1. Neuroanatomy & Brain Function – Brain lobes, limbic system, basal ganglia, thalamus,
hypothalamus, and associated clinical presentations
2. Neurotransmitter Systems – Serotonin, dopamine, norepinephrine, GABA, glutamate,
acetylcholine, and their synthetic pathways
3. Receptor Pharmacology – Agonists, antagonists, partial agonists, inverse agonists, and
clinical applications
4. CYP450 Drug Interactions – Inducers, inhibitors, and their impact on psychotropic
medication levels
5. Pharmacokinetics – Absorption, distribution, metabolism, excretion, half-life, steady-
state, and first-pass metabolism
6. Antidepressants – SSRIs, SNRIs, MAOIs, atypicals, and serotonin syndrome
7. Antipsychotics – First-generation vs. second-generation, EPS, metabolic effects, and
clozapine monitoring
8. Mood Stabilizers – Lithium, valproate, lamotrigine, and therapeutic monitoring
9. Anxiolytics & Sedative-Hypnotics – Benzodiazepines, appropriate prescribing, and
weaning
10. Ethical, Legal & Lifespan Considerations – Informed consent, involuntary commitment,
and special populations
SECTION 1: NEUROANATOMY & BRAIN FUNCTION (Questions 1–15)
1. A patient recovering from a stroke has trouble with speech comprehension and works with
a speech therapist twice a week. Which part of the patient's brain has been affected by the
stroke?
1|Page
,2
A. The Broca's area
B. The Basal ganglia
C. The Limbic system
D. The Wernicke's area
Answer: D
Rationale: Wernicke's area is responsible for speech comprehension. Damage results in
receptive aphasia where the patient can produce speech but cannot understand language.
Broca's area is responsible for speech production .
2. Which lobe of the brain is primarily responsible for visual processing?
A. Frontal lobe
B. Parietal lobe
C. Occipital lobe
D. Temporal lobe
Answer: C
Rationale: The occipital lobe, located at the back of the head, is the visual processing center.
Damage can result in visual disturbances or blindness. The temporal lobe processes auditory
information, and the parietal lobe processes touch and spatial relationships .
3. The hippocampus is primarily involved in which function?
A. Emotional regulation
B. Formation of new memories and spatial navigation
C. Motor coordination
D. Visual processing
Answer: B
Rationale: The hippocampus is essential for the formation of new memories and spatial
navigation. Damage can result in anterograde amnesia (inability to form new memories). It also
regulates stress responses .
4. Which brain structure serves as the sensory relay station, receiving information from the
body (except smell) and relaying it to appropriate cortical areas?
A. Amygdala
B. Thalamus
C. Hypothalamus
D. Basal ganglia
2|Page
, 3
Answer: B
Rationale: The thalamus is the sensory relay station of the brain. It receives sensory information
(except olfactory) and relays it to the cortex. It also plays roles in motor control and
consciousness .
5. The hypothalamus is responsible for regulating which of the following?
A. Memory formation
B. Homeostasis including hunger, thirst, temperature, and sleep
C. Emotional expression
D. Fine motor coordination
Answer: B
Rationale: The hypothalamus regulates homeostasis, controlling hunger, thirst, body
temperature, sleep-wake cycles, and the autonomic nervous system. It also links the nervous
system to the endocrine system via the pituitary gland .
6. A patient presents with personality changes, difficulty controlling emotions, and impaired
executive function. Which lobe is most likely affected?
A. Occipital lobe
B. Temporal lobe
C. Frontal lobe
D. Parietal lobe
Answer: C
Rationale: The frontal lobe is responsible for movement, intelligence, abstract thinking,
organization, personality, behavior, and emotional control. Injury can result in personality
changes and difficulty controlling emotions .
7. The amygdala is involved in which of the following functions?
A. Language comprehension
B. Emotion, interpretation of expressions, and sexual stimulation
C. Visual processing
D. Motor coordination
Answer: B
Rationale: The amygdala is linked to emotion, interpretation of expressions, and sexual
stimulation. It plays a critical role in the fear response and emotional memory, and
communicates with the ventral tegmental area in addiction .
8. Broca's area is located in which lobe of the brain?
