NR 546 Advanced Pharmacology Midterm
Exam 2026/2027 | Psychopharmacology
PMHNP | 100 MCQs with Rationales
This comprehensive review guide is designed to prepare students for the NR546
Advanced Pharmacology Midterm Exam, focusing on psychopharmacology for
the Psychiatric-Mental Health Nurse Practitioner (PMHNP). The exam covers
neurobiology, pharmacokinetics, pharmacodynamics, and medication
management for psychiatric disorders
SECTION 1: NEUROBIOLOGY FOUNDATIONS (Questions 1–15)
Question 1
Which brain region is primarily responsible for executive function, decision-
making, and is implicated in the negative symptoms of schizophrenia?
A. Amygdala
B. Hippocampus
C. Prefrontal cortex
D. Nucleus accumbens
C. Prefrontal cortex
RATIONALE: The prefrontal cortex (PFC) governs executive function, working
memory, impulse control, and emotional regulation. Hypofunction of the
mesocortical dopamine pathway (VTA → PFC) is linked to negative symptoms of
schizophrenia (avolition, alogia, flat affect). The amygdala processes fear and
anxiety; the hippocampus is critical for memory formation; the nucleus
accumbens is the core reward center .
,Question 2
What area of the brain is most associated with cognitive symptoms (executive
dysfunction, working memory deficits) in psychiatric disorders?
A. Orbitofrontal cortex
B. Dorsolateral prefrontal cortex
C. Amygdala
D. Hippocampus
B. Dorsolateral prefrontal cortex
RATIONALE: The dorsolateral prefrontal cortex (DLPFC) is critical for executive
functions including working memory, abstract thinking, cognitive flexibility, and
decision-making. Dysfunction here produces cognitive symptoms seen in
schizophrenia, depression, and ADHD. The orbitofrontal cortex regulates
emotional impulses; amygdala processes fear; hippocampus consolidates
memory .
Question 3
The hippocampus, located deep in the temporal lobes, is primarily involved in:
A. Motor coordination and balance
B. Anxiety responses, memory formation, and converting short-term to long-term
memory
C. Visual processing and object recognition
D. Regulation of hunger and body temperature
B. Anxiety responses, memory formation, and converting short-term to
long-term memory
RATIONALE: The hippocampus is critical for declarative memory formation,
spatial navigation, and emotional regulation (via connections to amygdala and
HPA axis). It converts short-term to long-term memory and is vulnerable to stress
(cortisol), explaining hippocampal volume reduction in depression and PTSD. This
supports the neurotrophic hypothesis of depression .
,Question 4
Damage to the parietal lobe, particularly the anterior portion, may result in:
A. Visual hallucinations
B. Astereogenesis (inability to recognize objects by touch)
C. Personality changes and emotional dyscontrol
D. Impaired short-term memory conversion
B. Astereogenesis (inability to recognize objects by touch)
RATIONALE: The parietal lobe processes sensory information including touch,
pain, temperature, and spatial relationships. Anterior parietal damage can cause
astereogenesis—inability to recognize objects through touch alone—sometimes
seen after cerebrovascular accidents. This demonstrates the parietal lobe's role in
somatosensory integration .
Question 5
A patient has difficulty recognizing faces (prosopagnosia) despite intact visual
acuity. Which lobe is most likely affected?
A. Temporal lobe
B. Occipital lobe
C. Parietal lobe
D. Frontal lobe
B. Occipital lobe
RATIONALE: The occipital lobe contains primary and association visual cortex.
Bilateral damage to visual association areas can cause visual agnosia—inability to
recognize items by sight despite intact vision. The fusiform gyrus (temporal-
occipital junction) specifically processes faces. This illustrates hierarchical visual
processing .
Question 6
, The structure that connects the two cerebral hemispheres and facilitates
interhemispheric communication is the:
A. Thalamus
B. Corpus callosum
C. Basal ganglia
D. Central sulcus
B. Corpus callosum
RATIONALE: The corpus callosum is the largest white matter tract, containing
over 200 million axons connecting homologous areas of left and right
hemispheres. It integrates motor, sensory, and cognitive functions across
hemispheres. Damage causes "split-brain" syndrome. The thalamus relays sensory
information; basal ganglia control movement; central sulcus separates frontal
from parietal lobes .
Question 7
A patient presents with aggressive outbursts, impulsivity, and poor emotional
regulation following traumatic brain injury. Which brain area and connection is
most likely affected?
A. Occipital lobe and visual cortex
B. Orbitofrontal cortex and its connections to the amygdala
C. Parietal lobe and somatosensory cortex
D. Cerebellum and motor coordination centers
B. Orbitofrontal cortex and its connections to the amygdala
RATIONALE: The orbitofrontal cortex and its connections to the amygdala
regulate emotional impulses and aggression. Damage here disinhibits aggressive
responses and impairs social judgment (Phineas Gage classic case). The occipital
lobe processes vision; parietal lobe processes sensory information; cerebellum
coordinates movement .
